This week I learned how to use a plasma cutter. I also learned how to disassemble an air break canister  easily.  I successfully trouble shot an air brake failure. I learned how to find the possible leak points in the schematic and how to pin point the issue. I also have disassembled a control modulating valve for ABS but that post is for tomorrow and I will also take that opportunity to post the pictures I have taken in class throughout the week.

This week I learned how do disassemble, inspect hand reassemble air breaks on truck trailer drive and steering hubs. After following the recommended Wheel bearing adjustment 618. Here is a video of me using the dial indicator to test the free play to make sure it is to specification.

Last week I learned what cavitation is like and the symptoms it produces. I also learned how debilitating a leak in a hydraulic system can be over time. This week I did a lot of my own research because I felt like I needed to know more on breaks before I felt comfortable enough to disassemble and inspect them. I read good portions of the references I was given by Jeff, which helped much. I understand the mechanics of it now… those break-apart diagrams I was seeing in class didn’t make any sense to me at the time, now I can identify the parts and functions easily. I also spent some time finding a couple of heavy-duty break jobs to do outside of school (haven’t done them yet)…. Too bad my camera died I will have pictures before the end of next week. I haven’t yet flushed the hydraulic fluid in the Kubota because I haven’t gotten the proper fasteners to fix those damned leaks.

 This is the tractor I am using to flaten my yard and dig a ditch for my electric.

I helped attach the back end digger it has its own hydralic system. This is the damned pin took quite a while of struggling to get in. I had to use a four by four and a brick..... But you gotta use what you got right?

I found two leaks this is one of them.

Here is the pump on the backend attachment.

Here is the rest of the system.

I went through and checked all the fluids

Here is leak number two under the hood.

Wow the oil is black.

This is one of the before pictures.

Here is the other tractor I have been using to pull everything out of the bushes. I love this thing look at all the sweet attachments.

So I successfully found the key off parasitic drain on the peterbilt... I have to say I found quit a bit of difficulty when I tried to use the same tactics I used on the international. I found it by checking the load on the fuses. Then used my meter to check the outlet (where the fuse box lead me). The outlet had no power so I pulled covers off and found a damned resistor behind the ash tray.       Hours this week:15.                                 Hours total:40

FQ 2013

This week was my first week back in class. It was intimidating at first because summer had taken its toll on my memory but for the first day we did a great exercise and brushed up on all the things the class I felt fuzzy about; connecting to the vehicles computer and deciphering codes, finding a short to ground, short, open and properly testing a battery. I have already tackled the key off parasitic drain problem on the shop's international. I am pretty comfortable with the amp clamp now and I doubt I will have too much problems (knock on wood (excluding extenuating circumstance)) finding the root of a parasitic drain. I also learned how to crimp connections on both large and small wires.

Hours this week and total: 25
