Break in belt squel

Colbymh · Dec 17, 2018

Before u immediately say deflection, I know. 2nd ride on rmk got just under 100
Miles on it.. towards end of ride the belt was squeling. Cearly too tight as when I lifted ass end up the track would free spin..

Sooo question. Dont they typically loosen up vs gettng tight????

My 18 did the same thing. Had about 50 miles on it and it got tighter quick. To the point i had to hold the break to keep from moving. Adjusted deflection and about another 40 miles had to adjust it again. Only had one more ride on it and it seemed fine. Just waiting on snow to try it again this season. Hopefully im good to go.

Deflection set screw is loosening off while riding.

Ya that could be it.. i’m about to unload from trailer so I’ll check it out. Thnx

Not likely. If they are on the border line of too tight they will only squeal when hot.

If you do find your deflection screw loosened up (mine did in the first 30 miles) disassemble and put blue loctite on the adjustment hole threads and reassemble. After I placed blue loctite on the threads it never happened again.

There were several 2018 sleds with a loose deflection screw, including my sled. I believe the threads in the sheave were cut a bit too large. Blue loctite takes care of it.

That was it.. check out pics of belt and clutch shaft? Should I just clean up shaft with parts cleaner and scotch brite or leave it alone? Also what ur guys take on how the belt looks.. kinda pisses me off it backed out. It was way loose

Deflection screw definitely loosens. Mine is non stop. Got some red locktite for it.

Clean the rubber off the shaft, or it will just get smashed into the sheave bushing.
The belt should be fine once the deflection is corrected.

Smart to take belt off or is it okay to do while still on?

1. Turn key off, remove tether.
2. Open secondary as far as you can with the Polaris tool, remove belt and spray acetone or brake clean(the harsh stuff with no environmental stuff in it) on the clutches and sheaves. Rotate clutches by hand to get all around.
3. Wipe clutch sheaves till the rag comes out clean.
4. Scrub sheaves with new burgundy scotchbrite.
5. Clean again with acetone and wipe till rag is clean.
6. Carefully wipe grease off belt.
7. Not recommended but spray belt with brake clean to blow off grease.
8. Fill sink 3" deep with hot water, use palmolive or dawn and scrub with a rag to remove grease.
9. Change water and scrub again till no grease is on the rag.
10. In new clean h2o, 3" hot water and soap, turn belt inside out scrub belt with scotchbrite. Get in between cogs really good.
11. Turn belt right side in and scrub like crazy, especially the sides using new scotchbrite often.
12. Rinse off with hot tap water.
13. Squeeze dry with a towel, not wipe and hang in your warmest room to dry.
It's a ton of work but the pic shows grease on the primary clutch and belt. If every last speck of grease is not cleaned off, it will contaminate the clutches and belt and burn up a $200 belt.
Go for it!

In the cogs, both inside and outside cogs, there can be oil on the belt. If there is oil in between, it can seep out onto the clutch sheaves and cause belt slippage. The outside is not as critical and it will fling gunk onto the belt guard which is cool as you can see what gunk is collecting on the guard.
Gunk, gunkety, gunkety gunk. Gunk is the word of the day.
