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.
To remove the Drive Chains:
1. Place the gearshift in the N (neutral) position.
2. Remove the oor pans.
3. Turn the tensioner cam assembly in the direction which
winds up the torsion spring and push the assembly down as
close as possible to the cam follower block in the bottom
of the frame. Secure it in this position with a Vice-Grip
10CR as illustrated in Figure 7-4.
4. Roll the vehicle until the connecting link on one of the
chains is visible.
5. Remove the spring clip from the connecting link as shown
in Figure 7-5. Remove the outside plate and tap out the
connecting link. The inside plates will be released when
the connecting link is removed (Figure 7-6).
6. Remove the chain from the vehicle.
7. Repeat steps 4 to 6 until all drive chains are removed.

MAINTENANCE INFORMATION
2. Ease the belt over the edge of the xed 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 requires
special tools. Return the vehicle to an authorized ARGO
dealer if the clutch units need servicing. The following indi-
cates that clutch service might be 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.
Clutch Inspection
Inspect the nylon sliders every 50 hours. The nylon sliders are
mounted in the driven clutch moveable pulley. (Figure 7-3).
When the clutch shifts, the cam moves on the nylon sliders.
Replace the nylon sliders before there is aluminum to alu-
minum 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.
