After rebuilding my 640 Ford with the help of people on this board and parts from YT I had a rear main leak. I installed another Fel-Pro crank shaft seal kit from beneath the engine 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 in and added silicone the best I could from beneath the tractor to the seating section of the 2 piece rubber seal where the original rope seal would have been seated in the block and cap.
I applied air pressure and soap solution to the engine as instructed by HOBO and still had a rear main seal leak. Not as bad as before but nothing I was comfortable with. That was the beginning of May. I had to stop all work for hernia surgery repair. Man that sucked as I had 4 hernias and I am now just supposed to lift 20 pounds. I hate being down to doing nothing.
Yesterday my son tore the engine apart while I supervised and found that the 2 piece rubber crank seal portion that was in the block did not get enough silicone on it to seal it completely. The bearing cap portion and side packing was completely sealed as I could easily access it. I guess that is what I get for not having enough time to do it right. I ordered and received a Victor 2 piece rubber crank shaft seal kit and will try it again. This time I am going to be able to completely silicone the rubber crank shaft seal into the block. Hopefully this will stop the leak. If not Im going with a rope seal.
