Customer and a friend, brought me a 1949 8n front mount dist tractor a while back and
and asked me to get it running, said it had been in his family every since new,was a
very low hours tractor that had been sitting a long time but they could not get it
started.He really did't want to spend a lot of money on it, but would like to see it
running again. It had been converted to 12 V. We checked all the usual stuff,got fire,
rebuilt carb. We got it started and it had NO oil pressure. We removed the relief valve
pumped it full of 90 Wt. and started it again. No oil pressure. Finally decided to pull
the pan to see if pick-up tube was broken. Every thing looked good.Pulled oil
pump,disassembled it. Looked new. Pulled main caps. Could tell they had been dry but no
damage. Saw a little rust in a couple of the cylinders. Pulled head, knocked pistons
out, no ring groove. Miced crank. Good condition.Everything in the engine was 100%
original Ford. Ordered a set of rings ,rod and main bearings and oil pump kit. Honed
block, rebuilt the oil pump( remembering I have all the Ford tools to do this little
job),definitely not the first one I ever did either. Plasti-guaged everything and put
her back together. Filled her up with 30 wt and started her up. Guess what NO oil
pressure. Shut it down. Did the old primer trick fired her up and horray 20 Lbs of oil
pressure. A measley 20 pounds. Changed the gauge and still 20 pounds. Changed the relief
valve and spring,18 lbs. Shut her off and let it set for half hour lunch break and fired
her up, No oil pressure. Primed the pump again and 20 pounds again. If the tractor sits
for over 30 minutes it looses it's prime.We have pressure checked the suction tube. The
pan is back off the oil pump is disassembled again and I don't know what the next move
really is other than dig a hole and bury the sucker. I have way more time and parts in
this thing than I ever charge for but I hate to give up. We have rebuilt 4 tractor
engines in the last month and this one has caused more problems than all the rest put
together. Anyone else ever had a similar problem?
