MAINTENANCE INFORMATION
5. Ease the belt over the fixed half pulley of the driven clutch
starting from the bottom of the clutch, while turning the
clutch counterclockwise until the belt is off. (Figure 7-3).
6. Remove the belt from the driver clutch.
Figure 7-3. Removing the drive belt
To install the Drive Belt:
CAUTION
If this procedure is not carried out as described, the edge
of the fixed face may cut or damage the drive belt.
1. Position the belt around the driver clutch first.
2. Ease the belt over the edge of the fixed face on the driven
clutch and at the same time, turn the inside, movable face
clockwise.
Drive Belt alignment and tension are pre-set at the factory
and are not adjustable. They are critical for proper operation
of the drive system. Return the vehicle to an ARGO dealer if
rapid belt wear occurs.
7.2.2 CLUTCH MAINTENANCE
Disassembly and repair of the driver and driven clutch re-
quires special tools. Return the vehicle to an ARGO dealer
if the clutch units need servicing. The following indicates
that clutch service is required:
•
a drop in vehicle performance
•
the clutch does not shift smoothly
•
the clutch sticks during vehicle operation
•
the drive belt wears rapidly
•
the vehicle vibrates severely during operation
•
the vehicle does not accelerate when the engine speed is
increased with the transmission in gear
•
transmission will not shift smoothly into gear at engine
idle.
Figure 7-4. Location of the sliders
Clutch Inspection
Inspect the nylon sliders every 50 hours. The nylon sliders
are mounted in the driven clutch moveable pulley. (Figure 7-
4). When the clutch shifts, the cam moves on the nylon sliders.
Replace the nylon sliders
before
there is aluminum to
aluminum contact between the cam and the movable pulley.
Driven clutch disassembly is required to replace the nylon
sliders properly. Return the vehicle to an ARGO dealer for
service.
7.2.3 DRIVE CHAINS
Roller chain “stretch” results from wear to the chain pins
and bushings because of the loss of lubricant.
To prevent sprocket damage and unnecessary breakdowns,
replace the chains when:
•
the chain tensioner can no longer take up the chain slack.
•
the chain is rubbing on a frame cross member.
•
the chain is seized due to rust and lack of lubrication.
•
the chain climbs the sprocket teeth, especially noticeable
when turning.
