JD MODEL A, styled. I believe it is the transmission shaft cover on the left side of the main case behind the flywheel. It is the cover with the mark for lining up the flywheel to time the mag. Anyway, I poked a hole in it with needle scaler, can I remove that cover, repair it, make gasket and replace simple as that? Also, I am kind of picky about oil/ grease leaks. Behind that cover on same side is a bearing holder with 3 bolts. I have gear lube leaking out from under that bearing holder. Can I remove the bearing holder and I believe the shim clean it up dope up etc without gutting the whole transmission to fix that leak. Thanks guys for the help.
