Although very similar to the Stuart G103 series engine and the engine in the LVT they are very different and not interchangeable. The LVT engine does have the dive shaft through the intake manifold but is still set up differently.

More Myths and track facts...M18 & M24
M24 T85E1 track can be used on the M18 Hellcat. But the entire sprocket and hub must be changed.
Detail - The M24 series tanks have a "drive hub" and sprockets. Sprockets are removable for either simple replacement or steel track or rubber track conversion. 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
