I recently came into possession of a 1979 John Deere 950 with 1,019 hours. I have no idea how long it has sat, but the battery that I took out of it had a date from 2012.
We have redone a lot of the wiring as it was all corroded or chewed up from mice over the years.
We put a new battery in it, added antifreeze, and fresh diesel to it. The oil looked completely new as did the fuel filter.
The Tractor started right up and we let it idle for about 15 minutes. A couple of weeks later we started it and drove it for about 30 minutes. We tried to use it to pull a small tree up out of the ground and I noticed when it was under load it was spewing either diesel or coolant out of the blow by and quit once it wasn’t under load anymore. We drove it a little more and parked it. The next day it would fire up. After working on it a few days we figured out the injector pump was so gummed up that it wasn’t hardly moving and not getting enough fuel to the injectors. We got it cleaned up where it was moving freely and it started right up. After we had it idling for a few minutes we revved up the motor and it started making screeching and grinding noises like the motor was trying to lock up. It sounded like it may be coming from around the crankcase, but I’m not 100% sure. If we took the compression off the cylinders for easy starting it spins freely with no noises or issues, but Once we put the compression back on and it starts to fire up the noise would start and it would struggle to run and die. We finally got it to start and not make the noise anymore. We noticed quite a bit of smoke coming out of the blow by and also these small tar like deposits all inside the engine compartment which was also what was covering the back of the injector pump keeping it from moving. I’m afraid to run it not knowing what the sound is.
If I can get some some assistance with finding out what the tar like deposits are, why there is smoke/liquid coming out of the blow by, and what the noise coming from the engine compartment could be I would really appreciate it. I have never messed with a diesel motor before so this is all new to me.
