I have an old sears roto spader model # 785 294450. I am looking for the roller bearings and oil seals for the gear case. The gear case number is 511684. This is a worm drive unit.

Check with Sears parts, it is one of theirs.

Any luck? I am buying an older Craftsman Tiller it's the Roto Spader with a new engine "the guy who is selling it put an engine from a different application on it and it works awesome. Let me know if you find a source for parts - they do NOT make them as solid as these anymore.
