SINGLE SPEED SPUR/BEVEL GEAR TRANSMISSION
Description
2. Remove transmission belt cover.
3.
4.
Remove both rear wheels.
This basic transmission has been in use for several
years. There are minor variations, such as different
shafts on the bevel pinion gear to accommodate belt
alignment on different chassies. All use a bevel pinion
input gear which mates with a combination bevel/spur
gear, which drives a final spur gear.
Remove retaining ring, spring, thrust washer, and
pinion from both axles (Fig. 028). Refer to “Wheel
Pinion Clutch” on page 5-3 for additional information
about the clutch mechanism.
Lubrication
Proper lubrication for this transmission is 2.5 – 3 fluid
ounces (7.1cc – 9.0cc) of lithium based No. 2 grease.
Transmission Removal and Replacement
1.
Raise the rear of the mower and support with a block
(Fig. 027).
