Scrambler Chain tightening

[catmandoes]

Had a strange issue with tighening my chain today.

I followed the instruction in the manual, loosened the concentric bolts, loosened the brake caliper bolts. Put a pin punch in the drive sprocket hole as instructed. I then rolled the quad forward slightly to tighten the chain.

However, when i re-tighted the concentric bolts the chain just went slack again (pin punch still in).

I finally reached some sort of balence by over-tightening the chain in the first place before tightening the cencentric bolts.

Does this sound a familer problem to anyone or am i doing somthing wrong.

Cheers

Danny,
You have to loosen the rear brake caliper support plate bolt as well (5/8s bolt and nut again further up the swing arm on the left hand side), otherwise the support plate won't allow the housing to move away from the swing arm thus the chain tension won't really change no matter how hard you turn it. You also end up bending the rear caliper out of alignment. Ring me I'll explain:) your also best to run the chain alot looser than Polaris recommend, they say 3/8's to 3/16's (5 - 10 mm) free play, but I'd go with actual slack on the swing arm so you end up with 10mm slack dragging not just up and down movement. A chain should always run slack you do less damage than running it too tight.

another good method is to adjust it with someone on the machine compressing the suspension, adjust it as far as you can so the chain is the tightest. when the load is off the chain will slack up, keep an eye on your swingarm bushings as when they wear out this will cause for premature chain and sprocket wear. and will not allow for proper chain tension.
