Dear gents,

Here's my situation: a few months ago I rebuilt my Gen V Eaton M112. New needle bearings, new coupler, new bearings and shaft seal in the snout, fresh oil.
It seems like it didn't go entirely smoothly — after 5,000 km a little oil is seeping past the front shaft seal.

At the same time, I currently have the opportunity to buy a ultra-low mileage used Gen IV supercharger, whose rotor pack coating is still completely intact,
My question is: is the Gen IV rotor pack compatible with the Gen V housing?

My idea is to swap the snout and rotor pack from the Gen IV supercharger into the Gen V housing, so that I can retain the advantage of the larger needle bearings from the Gen V.

Or was the rotor pack design also revised during the generation change?

Thanks and best regards, Alexander
