C. SPINDLE BELT REPLACEMENT

A worn spindle belt will affect the quality of cut from the
mower deck and should be replaced. Referring to
Figures 29 and 30, replace the spindle belt as follows:

NOTE

The two hex flange lock nuts and carriage bolts
securing the left side of the gear box mounting
bracket (See Figure 30) are removed from the
deck when replacing the belt. Clean any
accumulated grass clippings from the
underside of the mower deck to ensure proper
reassembly of these fasteners.

REMOVE SPINDLE BELT

Remove the thumb screws and bell washers se-
curing the RH and LH belt covers (See Figure 29).
Slide the tabs of the LH belt cover from the channel
bracket to remove the cover.

NOTE

Note the routing of the spindle belt to help
ensure proper installation of the new belt.

The idler bracket and movable flat idler pulley
are under spring tension. To prevent possible
injury, use caution when handling the idler
pulley.

Push the movable flat idler pulley (2, Figure 30)
toward the left side of the deck to relieve belt
tension; then roll the spindle belt off the movable
flat idler pulley.

Slide the belt off and over the LH spindle pulley.
Then pull the belt under the LH belt cover
mounting strap; off the fixed flat idler pulley and
center spindle pulley.

bolts (10, Figure 30) securing the left side of the
gear box mounting bracket to the deck.

bolts (11, Figure 30) securing the right side of the
