output side so that they can be reassembled
correctly. Using a soft hammer, tap case on the
tabs to break the seal, and pull halves E & F
apart.

spacer C. Also remove the bearings D and
grease seals.

INPUT SHAFT
7. Remove large double gear E, small gear F, key
G, and spacer H from input shaft J.

the existing snap ring K on new shaft). If the
shaft is NOT replaced, remove any burrs from
keyways and/or shaft ends if necessary.

(or replace gear if necessary). When replacing
bushings, make sure they are ush 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.
