ADJUSTMENT FOR REEL AND DRIVE BELTS
Belt tension may need adjusting due to run in and
normal wear. Inspect belts daily to ensure proper
operation of the unit.
NOTE: Reel and drive belt adjustments are guide-
lines only. The reel drive belts should engage with-
out slipping and disengage completely. The drive
belt should engage without slipping and disengage
so that the unit will not creep.
Remove the transmission drive belt cover.
REEL DRIVE BELT.
Engage the reel drive clutch. Measure the
distance between the reel drive belts and the
forward edge of the idler assembly belt stop.
Measurement D should be 3/4" (19 mm). If the
Reel belt requires adjustment the Transmission
Drive Belt must also be adjusted. (Figure 1)
TRANSMISSION DRIVE BELT
Engage the drive clutch. Measure the distance
from the top edge of the idler pulley F, to the top
edge of the drive belt G. The measurement E
should be approximately 1-1/4" to 2" (32 to 50
mm). The Transmission Belt may be adjusted
independent of the Reel Drive Belt. (Figure 2)
REEL DRIVE BELT ADJUSTMENT:
1. Loosen the transmission mounting plate A
and chain idler sprocket hardware. Slide the
transmission/mounting plate assembly as far
rearward as it will go to provide slack in the
transmission drive belt.
2. Clean the underside of chassis to allow
movement of the engine and loosen the engine
mounting hardware.
3. Loosen the set screw in the locking collar C on
the drive shaft. Insert a punch in the small hole
in the collar and use a hammer to tap the collar
clockwise (opposite direction of engine rotation)
until it's loose (approx. 1/4 turn).
4. Loosen the hardware securing the mounting
plate B (supporting the reel drive pulley) and the
pillow block.
