2015

Haven't had a chance to update this in awhile, I've been busy working and oem training has taken up most of my free time. Here's some of my projects since I last posted.

International with a 466E, would not restart after being parked at a customers loading dock. This fuse is not blown but has a 2v drop across it, that is enough to keep the engine from starting because it is in the clean power harness which supplies the injector driver module and it has a minimum operating voltage.

After attending a four day International A/C training class in Chicago I have become the A/C tech in the shop it seems. Had an interesting problem with a IH 4300, the complaint was intermittent A/C operation at speeds over 60 mph. Two of our other techs had already worked on it and not repaired the issue... I road tested the truck and found that after 14 miles at 60 mph the A/C would indeed quit cooling until road speed came down below 35 mph, no codes present. Watching live data while it occurred lead me to replacing the compressor clutch, All readings normal, compressor clutch draw steady at 3.7 amps, however after 14 miles the high side pressure dropped down to static levels while the computer said the clutch was engaged. Backprobed the connector and test drove with a meter rigged to verify that the clutch had 12v power and ground. Turns out the issue had nothing to do with road speed but operating at over 2000 rpm overloaded the weak compressor clutch and it would eventually kick out. Installed a new compressor assembly and the problem was resolved.

This is another A/C problem, 2013 with less than 7,000 miles used as a lime spreader. Found that the evaporator was completely plugged even with the factory cabin filter and an aftermarket HVAC intake filtration system. The problem is that operator was running on recirculate mode and the recirculation filters are the old wire mesh type and can't filter out the lime/dust that enters the cab. Also they did not seal the factory fresh air intake well enough so the add on filter wasn't actually doing any filtering even if he did run on fresh air mode as it should have been.

Got my CDL this spring and just finished up my ASE certifications.

Road call out for a liftgate, operator error combined with a broken chain resulted in breaking the eye off the end of the fold cylinder. I was able to weld the broken piece back into the eye so the driver could finish his route.

Adjusting the engine brake on a Maxxforce after resealing the valve cover base under warranty. The truck actually came in for a check engine light which ended up being a dead short to ground in the EGR valve resulting in EGR and intake throttle valve faults as they share a power supply.

Replaced an automated engine controller on a generator, It was shutting the engine down for an overspeed condition without an overspeed input. The overspeed input is adjustable and based on the generator frequency output.
