Adjusting V-Belts - Toro Greenmaster 1000 Service Manual

Adjusting V–belts
To adjust belt tension on V–belts (Fig. 5), first check ad-
justment of clutch control. Refer to Clutch Control in this
section. If unable to attain the 7 to 9 lbs (31 to 40 N) of
force that is required in adjusting the clutch control, pro-
ceed to the next step.
1. Park mower on a level surface. Make sure engine
is OFF. Remove high tension lead from the spark plug.
2. Loosen retainer securing the V–belt cover and pivot
cover open.
3. To increase V–belt tension, loosen cap screws se-
curing the engine to the engine base (Fig. 12). Move en-
gine backwards in slots. DO NOT OVER TENSION
BELTS. Tighten cap screws.
4. Check that a force of 7 to 9 lbs (31 to 40 N) is re-
quired to engage the clutch control. Adjust engine in
slots as necessary to get required tension on V–belts.
5. After tensioning V–belts, check alignment of the in-
put drive pulley and input shaft pulley with a straight
edge.
A. Inside pulley faces should be flush to each other
to within 0.030 inch (0.762 mm) maximum (Fig. 6).
B. If pulleys are misaligned, loosen cap screws se-
curing the engine mounting base to the mower
frame. Slide engine from side to side until the pul-
leys are aligned (Fig. 7).
6. Tighten cap screws and recheck alignment.
7. Close V–belt cover and secure retainer.
