Driven Pulley Maintenance
Refer to Figure 6-6:
The driven pulley should be inspected for wear at the
cam shoes to prevent damage to pulley and pulley
compression spring.
Refer to Figure 6-7:
1.
Secure vehicle for maintenance. See "Securing
Vehicle for Maintenance" on page 25.
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”
above aluminum hub when measuring parallel to the
cam incline.
!
DANGER
Do not replace cam shoes without contacting your nearest Land
Pride vehicle dealer for help. The compression spring can
cause bodily injury if replacement is done incorrectly.

Replace all cam shoes if there is less than 1/16”
clearance between aluminum housings. Make certain
you contact your nearest Land Pride vehicle dealer for
help when replacing them.

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.
!
CAUTION
Make certain to keep fingers from getting caught between belt
and pulley when rotating belt over pulley.
Refer to Figure 6-6:
1.
Secure vehicle for maintenance. See "Securing
Vehicle for Maintenance" on page 25.
