I agree the photo and text aren't perfectly clear. Here's my understanding: The winch drum (not shown) surrounds the motor and gearbox, supported on the left by the black bushing (which fits snugly over the CIM), and on the right by the versaplanetary shaft. The whole thing mounts using the silver shaft collar and maybe? another bearing on the versaplanetary shaft?

A photo of the full assembly would be helpful
