Involved a couple plastic half circles and a bit of wire. I printed out the pics- check archives for the procedure. Front crank seal is easy- just pull the front cover, replace the seal and be careful to center the cover on the shaft before tightening. Re zerk on the pulley- IIRC only the older tractors, like WC, had the zerk on the end of the shaft. IIRC it lubed the outer end bearing. Don't remember if the WD45 had the zerk. [Reply]  [No Email]

The seal will go bad, if oil is not kept in the hydraulic reservoir, to lube that seal.. Ron. [Reply]  [No Email]

Vick the motor repair man at the allis chamlers factory showed me how many years ago. you don't cut on the gasket and you don't add to the gasket. If you want further imformation, email me. Rich B.

Front crank seal could maybe be done, but the rear is a 2 piece with the bottom half in the rear main cap and the top half in a casting behind the flywheel. Pan seals can be done, but to do them right I seem to recall the front and rear caps need to be lowered to add a piece of gasket. Zerk is probably to lube the bearings in the shaft.
