The inside of my tiller had grease in it but it was dry and very thick and difficult to remove. I reused the chains on mine, not much visible wear and no rust.

After cleaning up the case, I had to weld up a little patch from the bolts being loose. Some of the carriage bolt heads were sheared off as a matter of fact.

A pic of the shafts cleaned up and of the gaskets I made. I got a piece of gasket material form McMaster-Carr and cut them out. I saw he round ones for sale but I just sliced them out. Yes I used the cork, some people will say bad things about it but the impervious stuff is ridiculously priced and I used mr. gasket upon reassembly.
