Drive belt routing
Belt adjustment
The drive belt is tensioned by a spring loaded
moveable idler pulley. When the brakes are applied,
the drive belt is de-clutched. An adjustable linkage con-
nects the tensioner pulley to the brake shaft. A brake
link that is out of adjustment will prevent the moveable
idler from correctly tensioning and de-tensioning the
belt.
As the belt wears and stretches, the moveable idler
needs to push the belt in further to keep proper belt
tension. To do this, the ferrule at the end of the brake
link needs to be at the rear of the slot in the idler pulley
bracket.
NOTE: The moveable idler pulley has a damp-
ener on it. The dampener allows a slow, smooth
engagement of the drive belt. See Figure 5B.21
The brake link is adjusted to the rear of the slot in
the moveable idler bracket. This allows the brake pedal
can return rapidly when the pedal is released, while the
dampener slows the engagement of the drive belt.
To adjust this brake link:
NOTE: The belt must be on when performing
this adjustment.
1. Release the parking brake.
2. Remove the deck as described in chapter 8 Cut-
ting Decks and Lift Shaft.
