Splitting Wd45, what all should I replace

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Finally found someone to help me with splitting my Wd45. I'm assuming this has never been done on this tractor before and much should be replaced based on everything else I've done so far. Anyone willing to chime in and provide me with a good list of what I should definitely replace or check while it's split since this is such a hassle and I don't want to have to do it again in my lifetime?

	Because I have a hydraulic leak coming into the bell housing from that seal between the two, along with a few other hydraulic seals I want to replace. I also removed the inspection plate under the bell housing and founds shards of metal so likely need to replace the throw out bearing too.

	So, you are basically looking at a clutch shaft seal replacement (the oil leak) and possibly a foot clutch/pressure plate/throwout bearing/pilot bearing replacement as well. Engine removal to do this isn't that tough. Remember, overfilling the hydraulic compartment will cause hydraulic oil to leak into the flywheel area. The vent for the hydraulic compartment actually goes into the flywheel area. Edited by DrAllis - Yesterday at 7:41am

	YOu just need to pull the engine. No splitting required. Before you pull the engine, do some checking and try to figure out if in addition to leaking oil into the bell housing, oil is transferring between hte read end and hydraulic oil compartments. There's a double seal between them that goes bad after 70 years. While pulling the motor you may want to actually split the torqu tube from the transmissing and replace those seals. About 10 years ago I replaced the seal in the bell housing and the next year I was pulling it apart again and replacing the seals in the torque tube. I have an old thread on here about it but the pictures may be gone now.
