final post

I am really sorry Jeff but these are the only three pictures that my computer would transfer from email to the hard drive. That's the only way I know how to get them onto blogger. Any way I completed the 3516 tearing it totally down and rebuilding the head. I completed all of my measurements did well. I also worked some with my group to get the measurements on our engine as well. I completed all of my assignments that were given for using the computer to diagnose problems and pull codes and run tests. I helped Lucas a little bit on the Pete and many people on the 3516. I really enjoyed my time at BTC and feel like I have retained a lot from the program. I have gone from a farm boy who could do little more than get things kinda going to get them out of the field to some one who can actually fix things the right way the first time. It was fun Jeff and I'll have a big box of broken electrical parts for you to have when fall comes around :).

I have over 400 hours for the spring quarter.

quiz

This is the diagram that I had to draw for the quiz.

3516

This week I started tearing down a cylinder head on out Cat 3516. I took it apart and am in the process of taking all of the measurements that you would do if you were to actually repair it back to running condition. I have also diagnosed two hydraulic leaks at work on an Alamo mower.  It just turned out to be two cracked lines so it was a simple fix. I learned how to take the required measurements on the 3516.  I also relearned how to use a micrometer.

compact

This week I took apart and a front hub on a 3038 compact tractor.  It came in that the hub was leaking oil and when I pulled the tractor in I noticed that the top seal was leaking. I blew it apart and sure enough the seal had fused with the casting causing a leak. I replaced and reassembeled the hub. I also learned how to rebuild a perma clutch in a 4020 tractor and plan to install it today.  I also got a refresher and relearned how to wire up elcectical circuits on the final test.

PTO clutch

First off here is the rest of the electrical test boards that you have assigned. Also I found this site really helpfull when I was learning how diodes work, ( http://electronics.stackexchange.com/questions/54977/how-does-a-diode-work.  I think that it is really cool that they work like a check valve and only let current flow in one direction. At work I have been told to figure out why a PTO will not work properley on a 4240. I started by checking the hydraulic oil and I found that it was black and reaked of burned clutch material.  So I decided I needed to split the tractor to check out the PTO clutch and the evidence is in the picture above.  It was fried.

electrical

This week I have been working through the electrical test boards and have completed all that have been set up.  I also completed the twenty five question online pre test that was asigned to us. At work I have rebuilt a hydraulic cylinder.  I have also split two tractors for a clutch replacement and to rapair a transmition. I also tracked down why four work lights on a tractor had quit working.

repairing wiring

I'm sorry this is so late I posted it last week but it didn't upload for some reason.  This week I started to repair the wiring damage that was done to our vehicles at school.  I built a new positive cable and put a new end on the negative cable of the grey dodge 2500.  I also started tracking down what all the other cut wires were.  Lastly I got a job at Washington Tractor in Lynden as an intern in their diesel shop.

fixing a priming pump

This week I rebuilt the filter and priming pump system on the diesel drum at school.  The old one was a one piece system and the pump wore out and was leaking everywhere so we replaced it with this two piece one.  We had to refurbish the mount to fit the new filter and figure out a couple fittings that needed to be added to the new system.  I also learned how to reset the gauges on an air filter.

splicing cable

This week I was shown how to splice cable.  I know that what the picture shows isn't the best way to attach two cables but it would work in a pinch.  We also got the frame cut on the semi and got part of the new exaust pipe on.  We are waiting on parts to do the rest. I have also serviced some implements on my own time and did more research on removing that dozer transmission.

taking apart a semi 3

This week we pulled the back axle off the semi and prepared to set it on is stands.  We also prepared to cut the frame so we can make the motor mobile.  We also built the legs for the motor stand and are just waiting on the casters to show up.  I learned that no matter how long the an extension is it will apply the same amount of torque to the fastener.

A variety of things accomplished

This week we finally got the cummins running. We wired in the key switch so we can use the key to start it.  We also wired in the throttle peddle off of another truck in the shop so there is a working throttle on it.  We used an electronic pressure gauge on a quick coupler that was on the block to make sure that the motor was building oil pressure and it built up a steady 45 psi.  I also figured out why the engine on a tow behind brush hog would not start.  I started by testing the battery which was shot.  I replaced that and there was still no power going to the starter.  So i took my multimeter and found that there was power going to and from the key switch but not through the starter solenoid.  I tested it and found that there was way too much resistance in it replaced it and the motor fired right up. Finally we had a bearing go out on one of the hubs on our manure spreader on the farm.  The inner bearing had totally been destroyed and the seal didn't exist anymore.  The inside of the hub had also been badly worn by this along with the spindle so it all needs to be replaced. I am hoping to get parts for this soon.

taking apart a semi part 2

This week we continued to disassemble the semi.  We successfully pulled the drop axle and got it all set and in place to weld onto stands.  We also pulled all the extra hoses and wires off of the motor and plan to try to get it running this week.  I also learned how to use a tire hammer to dismount tires from the wheels.  Once the hammer was used to break the beads and remove the snap ring we took the tires in and set them on the bare frame of the truck and used it as a stand for beating the rims out of the tires. If there is anything good to say about this job it is that it is a good workout. I also have been doing research on a tranny problem on a John Deere 455G dozer that a local farm wants me to work on for them.

Taking apart a semi

I spent this week working with a couple of classmates to dismantle and International truck.  We tore it all the way down to the frame, axles, and motor.  I also learned how to use an inductor to heat up an individual nut.  It is way easier to use but not quite as fast as a torch.
