Loop the belt and push out of the V- groove of the drive 3.

pulley on the right hand spindle assembly. Lift the belt

over the pulley and out from beneath the spindle cover.

See Fig. 7-3.

Loop the new PTO belt and slide between the top of the 4.

drive pulley and spindle cover. Maneuver the belt around

and into the V-groove of the drive pulley.

Route the back side of the belt around idler pulley and 5.

between the idler pulley and idler bracket. Re-tighten the

hex screw and flange lock nut if loosened earlier. Refer to

Fig. 7-3.

Route the belt around the fixed idler pulley as shown in Fig. 6.

7-3 and re-install the deck as described in “Re-installing the

Cutting Deck” later in this section.

Changing the Timing Belt

WARNING! Be sure to shut the engine off, remove

ignition key, disconnect the spark plug wire(s) to

prevent unintended starting before removing the

belt(s).

To replace the timing belt, proceed as follows:

Remove the deck from beneath the tractor (refer to Cutting 1.

Deck Removal).

Remove the PTO belt drive pulley of the right hand spindle 2.

assembly as described in “Changing the PTO Belt.”

Remove the hex screw, flat washer, lock washer, shoulder 3.

spacer, and flange lock nut that make up the idler bracket

backstop. NOTE: It may be necessary to clean the underside

of the mowing deck to access the hex screw. Refer to Fig.

7-4.

Applying force to either the timing belt idler pulley or the 4.

timing belt idler bracket, pivot and hold the idler bracket

against the spring tension just far enough to allow lifting

the timing belt off and above the idler pulley. Carefully

release the idler bracket. See Fig. 7-4.

Loop the timing belt and lift out of the timing pulley and 5.

over the right hand spindle assembly. Maneuver the belt

between the drive pulley on top of the spindle assembly

and the spindle cover to remove.

Repeat the above procedure to remove the belt from the 6.

left hand spindle assembly timing pulley. Refer to Fig. 7-4.

Loop the new timing belt and maneuver the belt between 7.

the drive pulley on top of the right hand spindle assembly

and the spindle cover. Lower the belt until loosely around

the right hand timing pulley. Refer to Fig. 7-4.

Note the arrows on the top of the timing pulley on the LH 8.

spindle and on the drive pulley of the RH spindle assembly.

These timing arrows MUST be positioned 90° from each

other as shown in Fig. 7-5.

Rotate the RH spindle assembly to position the drive pulley 9.

timing arrow as shown in Fig. 7-5. Then with-out moving

the RH drive pulley, pull the timing belt tight against the RH

timing pulley, above the timing belt idler pulley, and over

to the LH timing pulley.

Turn the LH timing pulley so that its timing arrow is 90° 10.

from the RH spindle assembly timing arrow. Refer to Fig.

7-5.

While making sure not to change the position of either 11.

pulley, loop the timing belt over the LH timing pulley.

After making sure the spring is hooked onto the idler 12.

bracket and screw, pivot the timing idler bracket/idler

pulley against the spring tension just far enough to allow

you to lower the backside of the timing belt onto the idler

pulley. See Fig. 7-5.

Re-check the timing arrows on the two pulleys. If they have 13.

moved from the 90º position when tensioning the timing

belt, pivot the idler pulley to relieve tension on the belt

and re-position the pulleys. The timing arrows MUST be

positioned 90° from each other as shown in Fig. 7-5.
