More Myths and track facts...M18 & M24
M24 T85E1 rubber track can be used on the M18 Hellcat. But the entire sprocket and hub must be changed (from original). This is a post war modification just as the M24 was modified post war for rubber track (by replacing the sprockets). M24s came from the factory with T72 Series Steel Track.
Detail - The M24 series tanks have a "drive hub" and sprockets. Sprockets are removable, either for steel track or rubber track. They BOLT to this "drive hub". Because as mentioned above there are two different sprockets & tracks available for the M24.
M18 Hellcat does not have a drive hub and bolt on sprockets. It has two separate halves that bolt together to make one complete drive sprocket assembly. The "sprocket" (toothed part) is welded to the hub as an assembly. This is not just an M24 sprocket welded to a hub it is an entirely different component.
M18 Steel track is NOT the same as M24 steel track. M24 steel track will not run on any M18 sprocket assembly
M41 Series tank tracks, Sprockets and hubs do not fit M24 or M18
