Nov 26th "freightliner"

You can identify the problem of the freightliner with the scan tool. I found a few codes.Engine 1 108 Barometric pressure sensor.
-voltage above normal or shorted high.
-no count.
Brakes powerunit 5 wheel sensor ABS axle 3 left
-current below normal or open circuit.
-no count
Brakes 11 pressure modulation valvle ABS axle 3 left.

The switch turns on and off to give a signal. It turns off for a bit longer then cycles 3 more times and does two long off cycles which is the top dead center. the first on is to let it know that TDC is coming up.

I thought it was pretty cool to be a able to see everything like this. So simple and i bet in the future you will be able to tell the computer to sit at TDC and it will and we will have plug ins on every sensor without have to unhook anything.

Nov 25th " first split"

So this is my first tractor split on a Kubota b7500 ill have more info later on how it all goes.

Nov 14th "day 33 sheet"

1 The affect of antifreeze on the radiator size is that with more glycol it has less ambient capability, about 1.8F for each 10% up to 50%. So with more antifreeze in the system you would need a larger radiator.

2 Detonation is when the fuel/air ignites and the flame front travels across the chamber. The end fuel gets too hot from compression from the flame front, a hot spot, bad fuel and combusts.The two flames collide and create a ping or "knock".

 

3 Deciding on when to service your machine should come from usage. how much how many hours and what conditions your working in.

 

4 “Combustion air flow requirements will vary, depending on the specific engine model and rating. Specific air flow data for Caterpillar engines is given in both…” Volumetric and mass readings.

Nov 13th "Dodge"

    So today i worked on the dodge. looking up the intake heaters and fuel control and using the scan tool on the truck itself.
    The FCA is the fuel control actuator. it controls the pressure of the fuel to atomize the fuel. The minimum psi it can run at is 9.5psi below that the warning comes on. There are two intake heaters, each heater gets 95 amps at 12 volts to heat.
    On the Dodge The codes for inj. 1-6 were on that they aren't working properly. Also the code for the intake heaters was on.
Turning the wipers and horn on were under the Body(fcm) section.
It was actually a lot of fun to work with the scan tool to do those things. really amazing how much you can get to on the vehicle from the computer even in a 2003. I learned that with the right tools and in the right situation you don't have to open the hood and get led astray to diagnose the problem.

Nov 4th " finding my place"

This week at work I got to finish sprucing up an old John Deere with alot of new paint. Learning that i do like to pay attention to the details alot. Also cleaning up some tractors and learning how the new company likes things done. you have to take note of everything and not just assume. At school i did some work with sensors when i had time outside class time. i worked with a position sensor and a pressure sensor. i still need to mess with the pressure sensor and how to hook up to the wires. WOndering if there is a general plan for color coding so i can know what to go to right away and not just try and guess my way through it. Also at work i have been doing some small put together stuff like excavator thumbs and buckets. its all just good progress in the right direction for where i want to be.

10/29 " hours & first tractor work"

This is really the first tractor i have worked on to any extent other than maintanence. I got to take off the front axle to get to the pinion seal and im replacing that and i might get to split it to get to the other leaks it has. Its so great working on these smaller tractors getting a feel for everything. i picked up the axle and put it on the table. its much less intimidating that way.

Oct 21st "First week"

    This was my first week at my new job with Scholten Equipment in Burlington. Its another tractor dealership shop. they mainly deal with Kubotas. My first week went so great. I am doing some chores but getting to see how some of these tractors are split and how they work on the inside. I dont know if this applies to everyone but i have see tractors split and talked about them time and time again and still felt confused to an extent. But with these three cylinder Kubotas split and helping split them it feels so much more possible. Maybe just the size of them or that these dont have all the a/c and other auxilary functions but i undeerstand the inside much better. I have done some small put together stuff like putting a tailgate on an rtx 500. and putting the tall stack back on a larger tractor. But all in all i have realized that the atmosphere of your workplace greatly affects how you learn. even the smaller things you dont see so always have that in mind when your working. Are you learning everything you can? Can you learn faster? and do you even feel like your accomplishing anything? If not you better think about that.

Oct 17 "Lethal strike"

I knew that this could happen with air and water but i never thought of oil. Also your body probably rejects the oil alot more and causes way more damage. to think all those times i was messing with pressurized hydraulic lines. Its amazing how fast it happens. I have seen stuff like that happen in my work place where small accidents never get reported. and if that happened i think someone would blow it off for sure.

Oct 14th "engine disassembly"

These were the First stages of disassembly. Where we brought the engine over to our working area and starting taking the head off. These are beforew we got the pistons out and started taking to crankshaft out. We found that there was heat on the connecting rod that may have caused the blowout of the bearing. We cleaned all the parts that were in the bottom of the pan to see if there was heat or anything else of significants. Im learning that nothing can be overlooked when doing failure analysis. Its not just about finding the part and replacing it! Alright if you just do that then it may happen again and wont you feel stupid! Find the problem Problem solve dont be a parts thrower. I really like doing this kind of diagnosing becuase its challenging and always interesting.
    We took off all the other connecting rods and found no heat and are trying to figure out if maybe the oil flow had a probelm and let the bearing get too hot.
    I am all done at Farmers EQ. company.  I am moving onto scholtens equipment.

    So the first picture is what i did on saturday. I repainted the jacks and rewrote the tonnage on them. just a small job that occupied my saturday.

This is a video of the lighting board after i completed it and testing it.

This week i put in my notice and im moving to Scholtens eqiupment in Burlington. I learned to do things that i need to that are not easy sometimes. Figuring out the light board was fun too. Im still learning about the two stroke motors some but i have learned alot this week.

"Week two working" 9/30

This week we worked on the DC motors and in class we actually made one! Ill post a video. at work i was working on a G30R. its a cool little tractor and i did a full service on it. i changed all the oils and changed the glow plugs. the mower deck hooked to it got new blades. the last thing to replace is the engine belt and i will be doing that on monday then test running it. I helped put a rake together and helped on a tranmission job. I learned this week about diagnosing with electrical. when i did the glow plugs and testing the glow plugs.

This is a really old video but the first 10 or 15 minutes are really helpful. and they talk about all the thengs that effect your power produced.

"First week back" Sep 23rd

    The first week back at school has been great. really getting to dive head first into electrical has been awesome. being able to pull stuff apart and test it and see the process is perfect for me to learn. i did like going through the lighting boards to map out how a truck works. also at work on Saturday i pulled a glow plug and hooked it up to test it. and before i pulled it i tested the voltage and the resistance between the plug and the ground to see if they were burnt out or not.

8/5 Hours and more Updates

    I have finished the power unit now all thats left is a couple fittings. I got to run it and it works great I wish I could see it actually pump to make sure everything works. I got to go out on two service calls  with other mechanics. one to pull the front drive case and take some picture and that went great i learned some tricks of working in the field. Like how to have buckets set up ways to stay organized and how to work faster.
    The other service call i went on was to get the suction end of the crap pump to stay close to the surface so they can flush out the barns. The old float had a hole in it and took on water. First we were tasked in finding the dam thing with a metal pole. We could find anything from the shore. So we got in the boat  to float out into the lagoon. I was so scared to be out in the lagoon growing up the was the one thing you never ever did was go in the lagoon. so we paddled out and drug the pole from one end to the other until we hit something. We found it had to pull it up above the water and it was full of crap and very heavy. But we got it up and i went elbow deep in the crap to tie on two sealed buckets for floats.

July 15th "SAFETY"

So i hate to be the one to bring this report but everyone makes mistakes. i had a power unti with pump and radiator attached on stands. i went to cut a support out out to move it down between the frame holding the rubber mounts to the engine. when i cut it the fram pieces kicked out and it tipped off the stand right in front of me. so obvious but easy to miss. Maybe if the engine was centered perfectly on the stands it might not have come off the stands but it wasnt. so in the end i didnt have a back up plan i should have had the A frame over it .

june 30th " hours and electrical"

    The last few days i worked on alot but most notable was an electical problem. they thought they had it figured out and the problem was fixed or at least gone... i went out to give a check over before it was sold. and i got the problem to come back up. it was an intermitent problem where you turn on the flashers and turn them off but they stay on. and some times with the key off they would work. after some trouble shooting here and there. i thought it was a relay  becuase i had tested the switch.  but i looked in the books and asked the boss and could not find anything about relays. i got help from a more experienced employee. and he found the relays and they were green with corrosion! replaced them problem solved. think basic basics basics.

6/10 " Learning Need To Report"

I have done so much and not even realized what im learning being so into my work. The other day i used the highlighting method on an electrical diagram for finding a problem in the circuit for an over the phone fix. We couldnt even see it. I also got to take apart and put back together a cvt clutch pack. I have seen them an helped with them but never really done it all with my own hands. I feel like i have much more confidence in tearing into things. I just wired up a new cb an antenna to our new truck. Learning how and where to wear add ons was challenging especially for how new the truck was. Another new thing was getting to see the planetary gear set i always just said oh ya that thing but seeing gear set work was great and helped with understanding the allison transmission for sure. Earlier i got to do a clutch replacement on our boom truck. and we ended up putting the clutch on the transmissioon first and then bolting to the flywheel so i hae learne ho to get past that challenge. But it is another beast all together working under a truck i enjoy tractors a bit more these days. In conclusion i need to notice the little stuff that really isnt all that little.

Hours to date 264!

5/30 Hours update

    I have Been working in the shop and getting a few of my own things to do. I did a full 1000 hour service on a skidsteer and learned some tricks and also things that i did wrong or the hard way. Also I Replaced a gas tank in one of our service trucks. someone put in a new sending unit and never put the gasket in so we had to get a new gasket and put it back together.

May 10th "Brake Job"

 First we get the wheel off fast with the impact gun. Remove the wheel.

 Next take off the drum. Inspect the brake pads and the inside of the drum.

 Take off th axle end cap.

 Pull out the pin or lock washer and nut and take bearing out with wheel hub.

 Inspect the wheels seal and remove if damaged.

 If you remove wheel seal check bearing and bearing race for wear.

 Inspecting....

 Take off the brake pads to be replaced etc..

 we removed the s-cam and inspected it.

 Neat and tighty!

 Driving the new seal.

 We put the s cam and shoes back on. to check the s-cam you measure end play and the vertical play and they must be under 30 thousandths.

 the wheel bearing setting goes as this. torque to 200ft lbs back off a full turn torque again to 50 ftlbs the depending on the wheel end back off betweem 1/2 and 1/6 turn. the end play for the bearing adjustment is between 1 and 5 thousandths.

Replace the axle cap and torque to a general torque by bolt situation. then replace the drum and wheel and torque wheel lug nuts to between 300 an 500 ft lbs

as of 5/5

This week at work we tore into a transmission and i got to see how some clutches work and how one of the transmissions work. just trying to keep up on everything in brake and make sure im getting the most out of it.

April 29th "Work At Home"

These week at work i learned abou assembly of new parts. Being very careful is important when things can be fragile and nu dont do preventative need to be kept clean. In school we started learning about air brakes and alot about what can happen to them if you dont do preventative. So the main thing i have been pulling from the last week or so is maintaning what you have be it new or old. With the time away from school i worked on my car to clock some time. I set the rocker arms and adjusted the air/fuel mixture the best i could and the idle. now i can say my old 71' wont die at every stop sign.

April 22nd "little things"

    Sometimes its just the little things left to pickup on. for me i really feel like iunderstand  pretty well general electrical systems. at least cicuit boards :/ .  But on my test i didnt know what there was a "dead post" so i learned what that was. i also saw that there was a small draw when i turned the key on in the truck.  At work i learned to always check if somethings works before you let the customer take it...  I thought i knew electrical well but after the large boards we did im excited to dicuss the results.

April 15th "oem test sheet"

    This week we went more into the circuit boards and I was trying especially hard to figure out the shorts to make sure i understood how they worked. I think i have the short figured out and the open and high resistance have come pretty easily other than a few mix ups. But now comes the interesting times when we start adding relays and outher components to complicate the boards and make them more like working on a machine. The learning about how relays work was cool. before i just thought oh cool it lets the big power through with a small amperage switch. But them when we got to see the inside and see how it really operated and what can go wrong with them it was very ineresting. I think the hardest part coming up will be dealing with multipl line circuits where there are more places to test and more places to get lost. The OEM sheet i need to do a test today on my car and another at least early this week. And i need to keep in mind that this test is to save time to get the most electrical information quickly. so if you cant do a test or can get to something skip it but remember at the end when viewing results that anything you missed can be the problem.

April 7th "back at school"

Starting back at school learning so electrical technical! I am just now learning the basics ohms voltage and amps. I tested out the first 16 boards and i think i have the basics down pat. and reading all about electrical schematics.

March 19th "Hours"

    Its been a long road or kinda short in my eyes but the first internship is over and its just about time to go back to school. Recently i have gotten to jump on with other mechanics with big projects to get an idea of how to do things and step to do them and alot of the easily forgotten things like tagging stuff as you take it off and ways to remember stuff. its been great and i have learned more then i thought i could in the time i was there. The sprayer project is almost done. today i buttoned it up and got rid of all the leaks and made sure the nozzles worked.


Hours total as of 3/19/12    325 hours

March 15th "nearing the end"

    Well the internship is coming to an end and has flown by. I have learned alot and gotten a few of my own projects in the past few weeks. Lately ive been working on a little john deere sprayer. The concept behind me doing this was learning about plumbing. But not only that but somehow at the same time learing hydralics and elctrical. They all have to flow they have filters and bypass' and can be learned through each other. I have learned about how to do simple things properly like just removing parts from a tractor the right way and helping speed up my time. Fabbing has been really fun learning about the welders and cutters. just learning so much from talking to people and asking questions like why not weld straight across a tube? or how does that work? get me more than i can chew sometimes. all in all i think i have takin a great leap into the feild and cant wait to dig into my first tractor project of my own!

March 1st " busy busy'

    I have gotten to work full time this week and last week as well except for the holiday. I am still learning how to do rolling torque on bearings. today i got to cut u-joints out of a drive line and tomorrow hopefully start putting it back together. Im doing alot of small fab work to help out the other mechanics like making one inch spacers for a big projects on the rear end of a tractor. or the brackets i put pictures of up to hold the oil radiators on with. But in the process im learning so much valuable information from the guys im working with and everyday im learning how to use a new tool or an old tool differently. all in all you can tell im absorbed in what im doing by lack of posting on my blog. Just feeling like im really out there in my career.
My total hours accumulated in Jan and Feb are 209.6

Feb 23rd "Seriously!"

Man time flies. I have been doing so many cool things! I helped finished the first Kuhn tiller with the radiators to cool the oil. I have started working on the second one and might even get to lead the projects a bit more. I have helped other mechanics tear into things and have learned a ton. Im in the process of learning how to preload bearings. I have read up on the procedure now i just need to watch it be done and then help and get a feel for it. Im running forklifts unloading trucks, fixing flat tires on random guys coming in just to pick up a forklift. A cool projects i have been doing on the side is makeing the mounts for  the vice on the back of a van truck and most rercently making the same application for a hose press. Some small things i have been picking up on but dont think about very often are... learning how to crimp my own hose fittings with the hydraulic press. I also learned how to press on hose fittings for other applications such as low pressure oil.

    Learning all the right times to ask questions, who to ask what question, where things are for everyday use, all of these things im still picking up on. One really cool thing that i have experianced a bit is just the fact that guys will ask me to help them. Hopefully that means it will help them speed up whatever it is there doing and also when i am helping them they are very eager to teach me all the tricks. I really love all of it and im having the time of my life. So much fun that i forget im even in school and im supposed to post on my blog...

    Thats all the recent updates i can think of at work. But everything is going great and everyday i learn ten new things.

"Fabbin" Feb. 16th

    This is some fabrication work i have been doing this week. They are going to mount two oil coolers on the back of this rototiller. I will have more pictures later of the finished product. I did all the welding on this job and am still learning welding so I had to grind them smooth but im getting alot of practice. also i am hoping to start getting some more hours and being paired with mechanics to help on jobs and learn.

Feb 13th Busy busy busy

I have been getting to do ALOT of fabricating in the shop lately. Im starting to get alot more responsibility for things to do task to finish. My plate is definitely full for now. I have almost completely replumbed the 2 50gallon oil drums for the new electric pumps with metering guns. Also i have been running errands like picking things up for people and dropping stuff off getting to know all the places we do business. Its getting exciting and interesting and i cant wait to see whats next!

Feb 6th

Today i did alot of small odd jobs mostly wrapping up loose ends of previous jobs. I finished rehanging a door and installed a light and vent on a company truck. We got our new Electric oil pumps that im installing in place of the pnuematic ones I installed about a month ago. Just alot of little things on my way to becoming well rounded. I hope to be able to handle anything!

Jan 28th "Been Lazy"

    Alright so lately i have been super lazy about reporting my info and my daily do's sorry.
But here we go the past week 23-27 I did some fun stuff and some not so fun stuff but i have really been learning alot from my job. Even if its know where stuff is in the shop or know when to just stop and ask for help! I have pressure washed some vehicles done alot of cleaning, i put together and tried to put togethere some machinery for the sales department and done some welding. the best part so far was the welding becuase its mostly new to me and fun to actually put something together that someone else is going to use later. so here are some pictures but not as much as id like to include.




These are plumbings that ive done.

Also some welding, cutting and tearing apert ive done.

Jan 13th "wrapping it up"

    All i did this morning was wrap up some projects that i started earlier this week. Then after lunch i started putting together some equipment from the lot. At the end of the day i started helping with a flail chopper, pulling it apart to get to a blown out panel.
    Just starting to get into the groove of things, having projects to finish and fitting in with the mechanics.

Jan 12th "Plumbing"

    Im finally punching in on work orders so we can keep track of what im doing and if im helping the compnay. I finished installing the pneumatic pumps from yesterday and labeled them for hytrans and 15-40w. Then boss sent me on a mission to plumb in an extra lina off the fill tank to fill our 50 gallon barrels faster, which took me the rest of the day and an extra hour even.
    What i take home for today is no matter what it is you cant just stop when its time to go home. get to a safe and careful place to stop before you go home.

Jan 11th Dues

    Clean Clean Clean. Cleaned around the shop  oil here metal shavings there. helped chris put back together his split john deere and he helped explain how the gears have to mesh. Tested two small water pumps and tagged one as not running. Right before i left i started mounting pneumatic pumps to 50 gallon drums. One for Hytrans and the other for 15-40 motor oil.
    This was a pretty slow day for me but i still had a great time. I reminded myself all day to keep moving becuase when you on the clock you better be doing something worth your wage.

Jan 10th Big first day

    Today was definitely a nerv-racking day for me. Not knowing what to expect never wanting to say i could do too much and then eatingmy words but not belittling myself. All in all the first day was amazing and let me know i chose the right place to be.
    Starting the day slow with paperwork and going through an orientation. Finally getting into a John Deere 790. We removed the rear wheels and disassembled the rear brakes. Inspecting the brakes finding oil which was causing chattering. i drained the hydralic fluid and put a new filter on. Greased the loader on the 790 and had to pull 4 pins to fix the zirks.
