The chain on my Scrambler 500 seems like it's loose nearly all the time. I tighten it, using a torque wrench on the bolts to match Polaris specs, and a few miles down the trail it's loose again. (Loose enough to rest on the small plastic plate that prevents it from rubbing on the swingarm). When it becomes loose, I hear a rubbing noise that I'm assuming to be the chain rubbing against the plastic chainguard. I do some small berm jumping while out on the trails, but I don't think that a chain becoming this loose so fast is normal -- even for a Scrammy. Would the HPD chain tensioner fix the problem (or is installing this even a good idea)? Is there something else I may be doing wrong before I spend money on an aftermaket part?

Thanks in advance!

 

Both HPD and Hot Seat offer good quality chain tensioners. They work good.

Some people say it puts extra drag onto the chain/drive assembly. I like mine, it keeps the "slop" out of the chain. Mine is an HPD I believe.

 

I have a shop manual that says the torque for the eccentric
locking bolts are 30 ft.lbs. but my owners manual says they
are 60 ft.lbs. My guess is you are not torquing them enough!
And----the chain tensioner will <u>not</u> help. I have one
on a 00 TB and it did not make any difference. It goes keep
the slack out when you jump. I'm jumping mine alot more now
with know problems at all.

 

When I read the shop manual for my TB it seemed like the torque was way too low. Now I just use two box end wrenches and tighten them to my liking. These bolts can be bought at any hardware store. So even if you break one, they are easily replaced.

 

Yea, the shop manual says 30 ft/lbs w/o trailer hitch, and 40 ft/lbs with one. Make sure you're torquing the nut side, not the bolt side. Also, just a tip, when replacing the bolts make sure those hardware store bolts are at least grade 5, preferably grade 8. Grade 5 is same thing as stock. You're right, good inexpensive replacements.
