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 bottom
of the frame. Secure it in this position with a Vice-Grip
10CR as illustrated in Figure 7-8.
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 7-9).
6. Remove the chain from the vehicle.
7. Repeat steps 4 to 6 until all drive chains are removed.

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 connecting
link as shown in Figure 7-10 and 7-11. When connecting
the RC50-2 chain, insert the inside plates before tapping
the connecting link into position.
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 replacement of
the connecting link is difficult without this tool. Modi
-
fied 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.
