Can the oil seal behind the cast aluminium fan be removed without removing the crankshaft? I am having problems removing the lube oil pump pressure relief valve and the main bearings seem to be OK, so was just going to change the big end bearings and the seals on the output shafts. I only intend to use the engine as a display so it won't see a lot of work.

Hi, As I'm new here I'm trying to put a handle on the term Listeroids, just what are they, what does the term mean?

I have a lister shearing plant to restore, and I'm wondering about the date of production. Although it consists mostly of angle iron the bearing housings and tumbling tommy clutch assembly all have lister in the castings or engraved on the brass covers. I have most of the plant, frame, engine and cooling water tank, but I'm told they didn't all start life together. The complete plant photo is from a museum, not the unit I have. Any information about these plants of leads to parts such as the down tubes would be much appreciated.
