Could anyone out there tell me how to tighten the chain on a Polaris 2004 Trail Boss 330? I would appreciate any help I help as I am single Mother. Thanks

 

Welcome to the forums.

In the first diagram, loosen part #14, both the front and back. (back one is pictured)

In the second diagram, loosen part #30. (one on each side)

If you have a really big set of channel locks or a pipe wrench, you should be able to spin the axle itself forward. Sometimes you can just roll it forward a bit. That should tighten the chain. Some models say to put a pin through the sprocket when you roll it. Never had to one mine, but it was an older model. Also, some say to have someone sit on the seat to compress the shock while doing this.

Once it's to the required tightness, just tighten the bolts back and go for a ride.

 

Thank you so much for the help, I'll get out there with my son and see if we can do it. Thanks again, have a great day! Sheryl

 

It sounds a lot more complicated than it is. Biggest mistake is not loosing the brake caliper. Good luck!

 

Don't go too tight either!! The chain will appear to have too much slack as it sits. But will tighten as the suspension cycles. Just have someone sit on the machine and watch the chain, see it tighten? About an inch of play as it sits no rider or extra weight is about right.
