6. Remove the transmission access cover from the
rear of the housing by pressing from underneath.
7. Loosen the gear selection control cable clamp
screw until the cable comes free.
Do not attempt
to remove the gear selection cable from the
control arm
at this time.
8. Turn the mower onto its right side and remove
the four flanged head self-tapping screws
securing the end caps to the housing.
Do not
remove the transmission at this time. See Figure
64.

9. Slowly pull the transmission from the housing
being very careful not to damage the gear
selection cable. Once clear of the housing, rotate
the assembly until the cable can be safely
removed.
Transmission Disassembly
Most repairs to this 'Series 2” transmission can be
accomplished without removing the pivot arm
assembly from the output shaft. Only
if components on
the output
shaft require replacement will pivot arm
removal
be necessary.
1. Remove the six flanged head self-tapping
screws securing the transmission cover to the
transmission case and remove the cover. See
Figure
65.
Figure 65
2. Before disassembling further, check for proper
operation of the input system, the gear reduction
system and gear selection system.
For more
information on this, see Transmission
Oper-
ation, page 41.
3. Removal of the input shaft and pulley assembly
can
be difficult because the input pinion will have
a tendency to turn as the pulley nut is loosened.
Address this situation by using an impact wrench
or by removing the 20 and 25 tooth gears from
the intermediate shaft and then putting the
intermediate shaft assembly back onto the
transmission. The hexagonal intermediate shaft
can then be held with a
7/16' end wrench while
the pulley
nut is loosened.
NOTE: Using a cut-away transmission cover to
hold the intermediate shaft
in place may facilitate
pulley
nut removal. See Figure 66.
4. Remove the intermediate shaft from the
transmission and clean.
Inspect all gears for
cracks and/or broken teeth. Inspect the
bushings
for excessive wear. Replace any parts
necessary. Be careful not to lose the two spacers
that fit between the bevel gear and the bushing.
