INPUT SHAFT
7. Remove large double gear E, small gear F, key

shaft is NOT replaced, remove any burrs from
keyways and/or shaft ends if necessary.

replace gear if necessary). When replacing
bushings, make sure they are flush with the edge
of the gear and that the oil holes on gear are
aligned.

ring K. Install the large double gear E, with the
small gear side against the spacer.
