Drive Belt Replacement
Replace drive belt when it shows signs of severe cuts, tears,
excessive weather checking, cracking and/or burns caused
by slipping. Slight raveling of belt covering does not require
belt replacement. Trim raveling with a sharp knife.
Inspect belt pulley grooves and flanges for wear. A new belt,
or one in good condition, should never run against bottom of
pulley groove except when engine is idling. Replace pulley
when this is the case, otherwise belt will lose power and slip
excessively.
Never pry a belt to get it on a pulley as this will cut or
damage the belt fibers.
Keep oil and grease away from belts and never use belt
dressings. Any of these will destroy the belt composition in a
very short time.
CAUTION: Securely support cargo box in
the up position to prevent injury when
working under the cargo box.
Make certain to keep fingers from getting
caught between belt and pulley when rotating
belt over pulley.
Refer to Figure 23:
1. Secure vehicle for maintenance. See Securing Vehicle
for Maintenance on page 24.

Driven Pulley Maintenance
Refer to Figure 23:
The driven pulley should be inspected for wear at the cam
shoes to prevent damage to pulley and pulley compression
spring.
Refer to Figure 24:
1. Secure vehicle for maintenance. See Securing Vehicle
for Maintenance on page 24.
2. Remove screws securing drive belt cover. Pull cover
back to inspect.
3. Check cam shoes on driven pulley every 100 hours or
less for wear. Cam shoes should be at least 1/16"
(1.6 mm) above aluminum hub when measuring
parallel to the cam incline.
DANGER: Do not replace cam shoes
without contacting your nearest Gravely
vehicle dealer for help. The compression
spring can cause bodily injury if replacement
is done incorrectly.
4. Replace all cam shoes if there is less than 1/16"
(1.6 mm) clearance between aluminum housings.
Make certain you contact your nearest Gravely vehicle
dealer for help when replacing them.

Engine Air Filter Maintenance
Refer to Figure 25 & Figure 26:
NOTE: Do not operate engine with a damaged air filter or
without an air filter element. Dirt will enter engine causing
dust ingested engine problems.
NOTE: Do not block air intake to air cleaner. Placing an
object on the platform in front of the air intake snorkel or
allowing loose clothing to drape over the snorkel could block
the snorkel opening.
