SERVICE NOTES
DRIVE BELT SLIPS
1. Lubricate contact surface under idler pulley bracket
2. Check idler pulley bracket mounting bolts for excessive
tightness. Idler pulley brackets must be mounted securely
but still must move freely.
3. Check control rod for improper assembly. If adjustment
tube is attached to lower end of control rod instead of
upper end, it may bind on control pivot lever and prevent
full use of tension spring.
4. Check belt guards. Belt guards must clear all points of
the ti^tened belt.
5. Check belt clips. These must not touch belt when belt
is tightened.
6. Check control rod adjustment. Adjusting the adjustment
tube on the control rod lengthens or shortens control
linkage.
7. Belt must be mounted on engine pulley. When assembling,
it is often mounted between pulley and reverse drive
wheel. It must also be mounted inside the stationary
belt guards.
REVERSE DRIVE
1. Reverse drive wheel should line up with its matching
pulley. Check mounting bolt in engine pulley for proper
tightness.
2. Matching pulley for reverse drive wheel must be assem­
bled as shown on diagram. The deeper groove matches
the reverse drive wheel. The shallow groove matches
the “V” belt.
3. Belt guards and belt clips must not touch the tightened
belt.
4. Reverse idler bracket must move freely. Check mounting
bolts for excessive tightness. Lubricate contact surface
under idler bracket.
5. Reverse should operate only when control handle
assembly is held in reverse position. Adjust control
rod for proper operating position.
NOTE: If belts are excessively stretched, replacement
will be necessary.
