SERVICE INSTRUCTIONS
Engine PTO Drive Belt (3 Groove Power Band) -
Model MD
1. To remove the engine PTO drive belt:
a. Remove the jackshaft drive belt from its idler
pulley (by pushing down on cold start lever)
and let the belt drop down out of the way.
NOTE: Step (a) is not essential to removing the
PTO belt, but it makes more room to work with the
PTO belt.
b. Loosen the brake band adjustment nut to
allow the clutch idler pulley to drop down
against the frame. This provides maximum
looseness of the belt to assist removal.
c. Remove the PTO drive belt by “walking” the
belt off of the engine and PTO pulleys one
groove at a time until the belt is completely
removed.
2. Install the PTO drive belt by reversing the removal
procedure. Check and make the following
adjustments:
a. Adjust clutch disengagement (brake band
adjustment) and check brake action.
b. Adjust clutch engagement for proper belt ten-
sion.
