After rebuilding my 640 Ford I got it together enough to let it run. I let it run on and off for 20 minutes at a gentle idle up to 12 hundred RPM s. During this time I adjusted the valves, set the timing and played with the lift.
Today I let it run for another 20 minutes, mostly at 15 hundred RPM s (PTO speed) but a couple of times I let it run at wide open throttle while I adjusted the carb and a couple of times I let it run at enough RPM s to let it move across the shop floor in 1st and reverse.
Everything worked well, the lift goes up and down, the clutch is smooth, the engine purrs like a kitten, no smoke, no blow by.
I shut it down to find a puddle of engine oil the size of a saucer under the tractor. The rear main seal is now leaking bad. I used the Fel-Pro crank shaft seal kit with the 2 piece rubber seal (which I staggered like the instructions said) and the rubber packing material with drive in pins. I siliconed the rubber side packing sections, but tried not to get any on the round seal halves.
Unless someone has a suggestion I guess it is time to tear the tractor back apart and reinstall a seal from beneath the engine. This task I do not look forward to as it appears that I will have to remove the crank from the bottom.
Should I clean and reuse the seal and packing and really silicone the time out of it or get a new seal? I still have the oil absorbing packing and rope seal that came with the engine gasket kit, but I thought those were nothing but trouble. Any suggestions would be appreciated as I read all I could before installing the seal the last time, and now I am really bummed out.
