Applying force to either the timing belt idler pulley or
the 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 pul-
ley. Carefully release the idler bracket. See Figure 7-4.
Figure 7-4
Loop the timing belt and lift out of the timing pulley
and 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 left hand spindle assembly timing pulley. Refer to
Figure 7-4.
Loop the new timing belt and maneuver the belt be-
tween 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
Figure 7-4.

Note the arrows on the top of the timing pulley on the
LH spindle and on the drive pulley of the RH spindle
assembly. These timing arrows MUST be positioned 90°
from each other as shown in Figure 7-5.
Rotate the RH spindle assembly to position the drive
pulley timing arrow as shown in Figure 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°
from the RH spindle assembly timing arrow. Refer to
Figure 7-5.
While making sure not to change the position of either
pulley, loop the timing belt over the LH timing pulley.
After making sure the spring is hooked onto the idler
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 Figure 7-5.
Re-check the timing arrows on the two pulleys. If they
have 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 Figure -5.
Re-install the idler bracket backstop components as
originally installed in the deck housing, and position so
that there is a 1/8" gap between the backstop and idler
bracket. Tighten the hex screw and flange lock nut to
secure in the adjusted position. •
