Not sure if I should post here or start a new one. I have a C20B - looks the same as this. The driveshaft seal is leaking - red fluid in both sides of this assembly. I've pulled the whole assembly out and see the seal behind a plate with four studs. Can't seem to get the plate loose. Is it just a cover plate or is it a capsule holding seal + bearings? I think I can pull it with an internal puller w/ slide hammer. ANyone been in that far? Is there another way to get that plate loose?
