OK, I've got 44 hand start A. Oil has been leaking out on the flywheel and slinging it over myself and the tractor and in a hour or so everything is an oily mess. I ordered both the rubber seal and the cork one. Parts book shows the same spacer for either seal but the rubber one was thinner with a smaller outside diameter so it fit pretty loosely in the spacer. I used the cork seal and let it soak in oil for half an hour and then put it on. After the engine was running for about 5 minutes oil started flying off the flywheel again. I pulled it off and all looked good, the inside showed some signs of the spines on the crank from when it slid over them but no depressions or cracks. The crank itself has some slight discoloration where the seal goes but is smooth. Thinking I may gotten the endplay too close and that may have an effect and not having ready access to another seal, I put a light film of silicone on the crank where the seal goes and put it back together with about 5/1000 of endplay. Same result, five minutes of run time, oil all over. So I ordered 2 more cork seals because they take 4 to 5 days and put one in when I got them. Again, same result.
I'm thinking either there is something wrong in my procedure or something else is amiss. The key slot on the spacer is wallered out a bit on the outside for about an eighth of an inch but them is good. Could this possibly have worn on the bearing cover and made the hole for the spacer too large and allow oil to leak out? The drain hole to the crank seems clear and I checked the crankcase breather to see if it was blocked and that seems clear, so I don't think it is a problem with the crankcase building pressure.
Other than that the tractor is running great and and I just got a 10' JD mechanical lift cultivator to play with, so I would like to not be an oily Ole while doing that. Any information on what I might be doing wrong or missing would be greatly appreciated.
