ya these numbers are to adjust your rpms for elevation and such. like bda said you should have something that says your opti max rpms should be. if you are under revving at full throttle try goin up a number until you hit your max at wot. if you are over revving go down a number. when i am in the mtns i am usually on clicker 3 or 4 and when i get back down to low elevation i am on clicker 1. i always run all three clickers on the same number but i have heard you can run one off number to finely tune it. but i just feel better about having them all on the same number.

That sled needs to be @ 8000 - 8100 RPM.

What elevation are you riding it at? and what are your RPM's when you hold it wide open?

The idea of the 1 - 6 numbers (called clickers) on the clutch are to help make minor adjustments for change in altitude so that you don't need to change your weights every time.

Basically, if you are at 2000 feet, and running at 8100 RPM when wide open, you are good. But if you take that sled to the mtns and ride it at 7000 feet, you won't be able to get 8100 RPM out of it anymore due to elevation. You might be at only 7500, which is not ideal. So you would look at your clickers. If you were at 2, for example, you could go up to 5 ( you can add about 150 - 200 RPM per clicker number), and you might be closer to 8100. Then when you head back down to 2000 ft, you will be over-revving like crazy, and need to go back to clicker 2.

Now, if you are not pulling 8100 RPM in the mountains and you are already on clicker 5 or 6, you will need to have the clutch taken apart and weight removed.

Adding / Removing weight is the best way to make big changes in your RPM, then use the clickers for "fine tuning."

I hope this helps. I tried to keep it pretty basic as it sounds like you don't have much clutching experience. If you have any specific questions, let me know.

I used to own an 08 X pkg and was in and out of it a lot.

Good Luck

Agreed.

Having clickers on different numbers means your clutch is not running up and down the ramps at the same rate (techinally the rollers are on different ramps).

Bad News I'd say. I've never tried it, and don't really think I would.

Ya. Never run different clicker numbers. The rollers will ride the ramps differently and will be spaced out different from the centerline and through your clutch balance extremely off!!!!

Dont do that! Seriously not good for the clutch, parts will scatter! Keep them all the same.
Ya like i said i would never do it cause like bandit said i felt like it would be out of balance with the ramp angle being diff for one but i swear i have hears from a couple dif ppl you can run one off number. Even when i did a search on dootalk a while back people where saying it doesnt hurt anything but i just dont feel comfortable doing it.

Talking about rear suspension adjusters maybe????

If you do not have clickers all the same on the clutch the bushings will be destroyed and more if u dont catch it soon enough

I figured out what all of the different numbers ment. would it make a difference witch way to turn them and how hard would it be cause mine isn't a quick clicker its just a stock clutch?

Can turn either way but sometimes need a wrench as the pivot of the ramps is stiff and takes some force to move it up the eccentric on the clicker

It's really easy and takes only about 5 minutes. Use a 10mm wrench to loosen off the nut, but don't take it right off. Just enough to get the head of the bolt out of the holes that they are in. Then use a 12mm wrench to turn the bolt to the desired clicker number.

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.
