Diagnostics

This week Don showed me how to pull codes using his scanner.  We were diagnosing a diesel truck that while it was warming up if you put your foot on the floor it would sound like the turbo would try to spool  up but it wouldn't accelerate it would just keep going at the same speed and start jerking.  We ended up pulling 16 codes from the truck but we still have not diagnosed the problem.  We suspect that it has something to do with the EGR valve.  I am also preparing to split a small tractor to adjust the clutch.

Starting problems

This Chevy diesel came into the shop with a starting problem.  It would start fine cold but if you let it warm up, shut it off, and let it sit for an hour and a half and then start it again it would start for about ten seconds and then die.  We thought it was getting air into the fuel system somewhere so we put a clear fuel line on the return line out of the injector pump.  Sure enough when it would start and die a large stream of air bubbles would come out of the injector pump.  We thought it might be the fuel filter housing so i pulled it off and checked the o rings on it.  Sure enough one o ring was flattened and another was bad and someone had tried to repair it with silicon.  We got new o rings for it and put it back together and i worked great with no problems.  I also replaced the bearings, seals, and brakes on one side of the rear axle of Don's service truck.

The baby tractor

This week I did a full service on this little New Holland Diesel.  I changed the oil, coolant and all the filters (all six of them).  I also did a coolant swap on a diesel pickup and learned how to use an electronic coolant tester.  It is way more accurate than the test strips.

Taking apart a Chevy

This 95  Chevy came into the shop because the owner had run the motor out of oil and seized it.  We determined that it would not be worth fixing for the customer and he decided to have us part it out for him.  We took off the entire intake assembly, the entire belt system, the gas tank, and the drive train.  We are going to be taking the heads also along with the wiring harnesses and steering unit.  I also did an LOF on a 2011 F350 Powerstroke.
