With about 2 hours on all the work I did on this tractor last week, which included a new rear main seal and a crank sleeve, my tractor was
running oil out of the bell housing from the seal again (I had it split and the flywheel/clutch assembly off in less than 90 minutes, I'm
getting good at this!). I took it apart, and it appears the seal lip has basically burned off (see pictures) and burned onto the
speedisleeve (hopefully it will scrub off without damaging the sleeve, as they are a bit pricy!). Here is how I installed everything:
1) clean crank with brake cleaner, installed speedisleeve with loctite 515 anaerobic gasket maker per the instructions
2) Pressed in new seal into the seal housing until it bottomed out on the flange machined into the retainer housing (about 1/8 inch below
flush from the front face of the seal retainer) all done with a press and a flat board so as not to distort the seal. It went in straight
and easy
3) Lubed the seal with EP grease.
4) Put a plastic wrap over the crank
5) installed the retainer (with new gasket and silicone around the oil pan gasket on the bottom) and everything slid on easily. Pulled the
plastic out from between the seal and the crankshaft, and it came out smoothly.
Did I do something wrong? I used an aftermarket seal, is this a problem with them? I have never had one do this in this short of a time.
Would the speedisleeve be messing up oil flow to the seal to keep it lubricated? I thought that might be it, but if that was the case, how
would it pour oil from the rear seal after the seal burned up. I didn't remove the installation flange from the speedisleeve because it is
usually only removed if there is an interface issue, which there doesn't appear to be on this crank. Plus, I get nervous removing them on
these thin little sleeves.
