D.
Reinstall the belt cover by placing the
cover in position. While maintaining a
slight gap between the cover seal and the
side plate, install each mounting bolt until
the threads engage in the insert. The gap
will allow visual alignment of the bolt to
the threaded insert. After all bolts are
installed, tighten until the stand offs inside
the cover contact the side plate. Do not
overtighten.
Primary v-belts (Fig. 32–33)
1.
To adjust belt tension on primary V-belts, first
check adjustment of the traction control. Refer
to
Adjusting The Traction Control
. If unable to
attain the 4–7 Nm force required in adjusting
traction control, go to next step.
2.
Loosen the retainer securing the V-belt cover
and pivot the cover open.
3.
To increase belt tension, loosen the engine
mounting bolts and move the engine backwards
in slots. DO NOT OVER TENSION THE
BELTS. Tighten the mounting bolts.
4.
After tensioning the primary V-belts, check the
alignment of the engine output shaft pulley and
countershaft pulley with a straight edge. If the
pulleys are misaligned, loosen the screws
securing engine mounting base to the mower
frame and slide the engine from side to side
until the pulleys are aligned within .0l76mm.

To push or pull the machine easier without
starting the engine, adjust the belt guide
(Fig. 33, inset) as follows:
A.
Engage the clutch.
B.
Loosen the capscrew securing the idler
pulley and belt guide to the idler arm.
C.
Rotate the belt guide clockwise until a gap
of approximately 1.52mm is obtained
between guide finger and backside of
drive belts.
D.
Tighten the capscrew and lock nut
securing the idler pulley and belt guide to
the idler arm. The 1.52mm dimension is a
starting recommendation the actual gap
may vary per machine.
Differential Belt Replacement
1.
Remove the capscrews securing the traction
drive and reel drive belt covers to the right side
plate and remove the belt covers.
2.
Loosen the idler pulley mounting nut on each
idler pulley and pivot each idler pulley
counterclockwise away from the backside of
each belt to release belt tension. Remove the
belts.
