We just finished rebuilding a Oliver 88RC with a Super 88 Diesel Engine. We had all the injectors redone, head work, and did a complete in frame rebuild. We replaced the Bocsh pump with a Roosa Master to correct a non-start condition we were experiencing once it got warm before the rebuild. Prior to the rebuild the tractor had operated fine until I was out running her through it's paces discing a maybe 3 acre plot. I was pulling good making good time about half throttle 5th gear. After about 3/4 of the field was done she started to have trouble and I had to shift to fourth to pull it easy. Long story short it got to the point where it wouldnt even budge it in first without stalling.
Tractor was back up at the farm and the symptoms are it will start for maybe 30 to 40 seconds running like a top then will die like you pulled the fuel shutoff. If you try to start it right after it stalls it starts very hard with a long cranking period. If you wait about ten minutes it starts up fine until it stalls like before. My first instinct told me fuel filter, I found that somehow it wasn't changed during the rebuild. I replaced it, no fix. I then cleaned and checked both sediment bowls (under tank, lift pump) and screens to find no issues. Next I removed the tank for the second time, cleaned it and installed a two inch piece of tubing in the outlet to prevent dirt from getting in to the line. All this and it didn't fix the problem. I believe it may be the lift pump now but I have heard these aren't really a common problem is this true? Also what is your guy's opinion on the situation, I hope I explained it enough. Thanks for your time.
