Hello There! Long time lurker, first time posting.
I've had a 1990 HDJ81 in California for almost a year now, and it's been a great rig. I recently had the ACSD pin shear (stupid me for not deleting it earlier) which sent a bunch of metal shavings into the IP and me chasing a couple small fuel leaks trying to solve the symptoms I was having.
The truck originally would not idle, had to have the throttle depressed about 1/4 way to get it to start, would die if the RPM was below 1200, but would run perfectly fine once it was in gear and moving faster than about 10 MPH. In fact, when the pin sheared I was on a road trip with a trailer, and the truck was perfectly happy cruising at 60MPH and I only noticed a problem when I pulled off the freeway to get a cup of coffee and the truck died as I was slowing down on the offramp.
Long story short, I fixed an air leak on the fuel filter cap(priming pump diaphragm), cleaned out all the metal on the IP overflow bolt, from around the fuel cutoff solenoid, swapped the POS ACSD for a block off plate and flushed more metal out the ACSD port on the IP, and hoped for the best. The truck runs noticable better, idles ok down at about 1000 RPM, and is generally derivable except for a hunting idle (about a 100 RPM swing), and occasionally the idle speed would stick up higher at 1200-1400 RPM. I figured this sounded like the governor was sticking and pulled the top of the IP open and found a couple more bits of metal and the small port in the little cup that rides on the governor shaft clogged. I cleaned out everything i could see, put it back together, and now the truck is pretty OK, but still has a small hunting idle when I put it in gear with my foot on the brake, and the truck wants to die when at ~600 RPM which I figure is still probably metal in and around the governor.
So, background aside, onto my question:
Does anyone have recommendations for a diesel shop on the west coast that they have experience with to do a full clean and rebuilt on my IP pump? This is my first diesel, and I do not have any friends who have had to rebuild an injection pump, and therefore do not know of a shop that can be trusted to do a good job. I have no problem pulling the pump and shipping it off to someone for a rebuild as well.
I dont have any good pics of the ACSD and subsequent destruction, but here is one of the rig.
Thanks!
