IMPELLER BELT
The impeller belt transfers power from transmission
jackshaft to impeller.
1. Turn off machine and set parking brake.
FOR SAFETY: Before leaving or servicing machine,
stop on level surface, apply parking brake, turn off
machine and remove key.
2. Raise rear cover.
3. Disconnect batteries from machine.
4. Remove the belt guard cover.
5. Release tension on impeller belt using tension
bolt under impeller arm.
6. Repeat Steps 5 and 6 under Rear Jackshaft
(Pump Drive) Belt.
7. Remove rear jackshaft belt from front pulley.
8. Remove impeller belt.
9. Replace belt and reverse Steps 1 –6.
TO ALIGN BELT
1. Loosen impeller belt, using the tensioning bolt
under the impeller arm.
2. Loosen set screws in the impeller pulley.
3. Slide the pulley side to side to make proper
alignment.
4. Tighten set screws in pulley.
5. Retighten impeller belt.
DIFFERENTIAL DRIVE CHAIN (Refer to the
Differential Group in the Parts section)
The differential drive chain transfers power from the
output sprocket of transmission to differential
sprocket. Check the chain condition and tension
every 200 hours of operation.
REPLACING AND ADJUSTING DIFFERENTIAL
DRIVE CHAIN
1. Raise the hopper and engage the hopper safety
arm.
2. Turn off machine and set parking brake.
FOR SAFETY: Before leaving or servicing machine,
stop on level surface, apply parking brake, turn off
machine and remove key.
3. Raise rear cover.
4. Disconnect batteries from machine.
5. Remove the drive motor dust cover.
6. Loosen 4 bolts holding transmission case to
mount.
7. Locate tensioning bolt at top of transmission
mount. Tighten or loosen bolt as needed to
properly tension chain.
8. Tighten 4 mounting bolts in transmission body.
If alignment of the chain and sprockets becomes
necessary, the alignment is accomplished by moving
the entire differential assembly side to side.
TO REALIGN
1. Raise the hopper and engage the hopper safety
arm.
Raised hopper may fall. Engage hopper safety
arm.
2. Turn off machine and set parking brake.
FOR SAFETY: Before leaving or servicing machine,
stop on level surface, apply parking brake, turn off
machine and remove key.
3. Remove rear cover.
4. Disconnect battery from machine.
5. Remove the drive motor dust cover.
6. Loosen all four locking on bearings supporting
the differential.
7. Loosen the set screws in the two brake disks.
8. Loosen but don't remove the hardware attaching
the bearing flanges to the frame.
9. Make sure there is little tension on the drive
chain. Gently slide the differential in it's bearing
to restore proper alignment.
NOTE: The brake disks must remain stationary
while the differential shafts move in them.
10. Reverse Steps 1-8. Follow tensioning
instructions above.
NOTE: After aligning the differential the small
sprockets at each end of the differential may need to
be realigned with the wheel sprockets. If so, loosen
setscrews in small sprockets and slide on differential
shaft until aligned. Retighten setscrews.
