TO DISASSEMBLE TRANSMISSION
ASSEMBLY (Refer to Figure 44 for assembly
sequence).
a. Place transmission in a vise with input shaft
end up. Clamp only the case, not the shaft.
NOTE: Supporting transmission in this manner
will allow oil to collect in the transmission case.
b. Before disassembling transmission halves,
mark outer edge of transmission case and
cover so two can be reassembled in the same
position.
c. Place transmission in vise so three of the
eight screws hOlding transmission case and
cover together are in the twelve, four, and
seven o'clock positions.
d. Loosen three screws, mentioned in step "c",
approximately two turns. DO NOT remove
these three screws at this time. Remove
remaining five screws and lockwashers
completely.
e. Remove transmission assembly from vise.
f. While holding transmission by cover end,
gently tap each of the three remaining screws
until two halves separate. Place assembly
back into vise (cover end up) and remove
three screws and lockwashers.
g. Remove screw and washer holding
reduction gear to transmission cover and
remove gear.
h. Remove special screw, lockwasher and flat
washer holding drive pinion to input shaft.
NOTE: To prevent input shaft from turning during
removal of spe<:ial screw, place an old helix onto
shaft and hold helix with a locking pliers.
i. Remove drive pinion from input shaft using a
hammer and punch to drive shaft out of
pinion.
j. Remove input shaft from transmission cover.
IMPORTANT: Carefully examine area inside cover
tube (seals, bearing, roller clutch, etc.). If oil is
present between seals and bearing, or roller
clutch is bad, it will require replacing complete
transmission cover assembly. These components
are not available separately.

TO REASSEMBLE TRANSMISSION
ASSEMBLY
IMPORTANT: Wash all components in a cleaning
solution (mineral spirits). Wipe inside of

dampened with cleaning solution, to remove any
impurities. DO NOT allow cleaning solution to
come in contact with bearings and seals in
transmission case and/or cover.
a. Carefully insert output shaft and washer into
transmis~ion
case.
b. Place agitator pinion on splines of output
shaft and press onto shaft.
