How to change the clutch on the 2008 summit x 800r? the readings on the side of the clutch are 1-6! Witch one should i have it on?

The OP have good advise, assuming all other parameters are correct.  For eg.  is your belt worn out? measure it.  what about belt deflection? have you checked that?  Track too loose or too tight? 

Also the 2008 summit X 154 and 146 came geared pretty high.   The 154 was 2.14:1 (21 top and 45 bottom) the 146 was 1.956:1 (23 top and 45 bottom)

After adjusting pin weight to gain max rpm on clicker 3  and everything else stock.  on groomed trail at 4000 ft my 154 would touch 98 mph and the 146 would hit 105 mph on gps, way too fast for mountain sleds. Both sleds hitting 8000-8100 WOT.   Put them in the deep snow though and they were all over the place, very inconsistent.  geared to 20 top, 154 and 21 top, 146 and was happier.

Manatee thank you for the information.

This is the best description of what the clickers do and why you have to adjust them.

I`m new to snowmobiling and was having a hard time wrapping my head around why you had to adjust the clutch

Glad to help.

If you any specific questions, shoot me a PM and I'll try to do what I can.


Clutching is one of the most fun and most hate things about working on a sled.  It's not like gearing where you just change from one gear to the next.  Clutches are infinitely adjustable with helix, weights, springs and clickers. 


Once you grasp the concept, you can play around a lot with your clutch and change your sled's attitude a little bit at a time.

However, if you don't grasp the concept, it's a tough one to play with to try and find troubles.

When adjusting, should one add loctite or similar once in a while? I added a little vibratite to 2 of the bolts - hopefully not an issue? If it is I can always remove using a wire brush.

Also, the washers would only fall out if the bolt comes out, not if you loosened the nut so it fell off (but the bolt stayed in place). Correct?

How often would someone typically adjust these during a ride?

Locktite won't hurt it. You should be good if the bolt didn't fall out. If you are not changing over 1000 feet elevation you don't need to change them once you get your max rpms correct. Basically if you are wide open throttle and max rpm is below 8000 rpm adjust clickers up. If you are above 8000 rpm adjust clickers to lower number. Each number changes max rpms by around 200 rpm.
