MAINTENANCE INFORMATION
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.
To remove the Drive Chains:
1. Place the gearshift in the N (neutral) position.
2. Remove the floor 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 bot-
tom of the frame. Secure it in this position with a Vice-
Grip 10CR as illustrated in Figure 7-6.
Use a pair of modified 7R Vice Grips to hold the ends
of the chain together while inserting the connecting
link. Some drive chains have no slack, and replace-
ment of the connecting link is difficult without this tool.
Modified Vice Grips can be ordered from your ARGO
dealer (ARGO Part No. 658-08) or refer to Appendix 1
for modification information.
3. Replace the outside plate and spring clip. The open end
of the clip must face rearward when it is on top of the
chain.
4. Remove the vice-grips, securing the cam assembly in its
lowest position.
5. Repeat steps 1 to 4 until all chains are replaced.
Figure 7-6. Securing tensioner cam
To install the Drive Chains:
1. Position the drive chain over the slider block and around
the drive sprockets.
2. Pull the ends of the chain together and insert the con-
necting link as shown in Figure 7-8 and 7-9. When con-
necting the RC50-2 chain, insert the inside plates before
tapping the connecting link into position.
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 7-7. Remove the outside plate and tap out the
connecting link. The inside plates will be released when
the connecting link is removed (Figure 7-8).
6. Remove the chain from the vehicle.
7. Repeat steps 4 to 6 until all drive chains are removed.
