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.
