Clutch alignment 09 M8, is this correct ?

[Rprecision]

Last time I was out I gernaded a belt running wide open down the trail, first in almost 600 miles. I am a little concerned as there are no shims between the secondary and D Drive. I wouldent put it past my dealer to have never aligned them.

I have a alignment tool and shims coming

Anyways I found this thread, its a little hard to read but I think I got most of it.

Offset is suposed to be .060 "

The Parallelism description dosent make any sense or explain how its adjusted?

What do I need to know ?

Thanks

Offset can be adjusted with shims behind the secondary.

But Parallelism is pretty much locked down. You don't have any slotted holes in the mount plate that attaches to the end of the block.

I believe the .060" is the difference that you target between the leading edge of the primary and the trailing edge of the primary measured on the fixed sheeve against your alignment bar. You want it to pull back into perfect alignment under load.

Again you don't have the adjustment like we did with the old 900's.

Luckily mine came out right on.

Ok so I understood the .060 clearence correct

Thanks

I'm in the same boat. I just checked mine and it's probably .060 off and I too have no shims behind the secondary.

Yet, I had no belt related issues last year, so I am a bit reluctant to change the alignment.

The Arctic cat manual says:

CHECKING OFFSET
1. Open the left-side access panel; then remove the
belt guard.
2. Install the appropriate clutch alignment bar (see
chart) between the drive clutch sheaves.
3. Allow the bar to rest on the drive clutch shaft and
against the outside edge of the driven pulley stationary
sheave.
��NOTE: The alignment bar must extend beyond
the front edge of the drive clutch.
4. With the bar against the outside edge of the driven
pulley stationary sheave at points A and B, the bar
should just clear the inside edge of the stationary
sheave of the drive clutch and rest on the stationary
shaft at point C. If the bar either will not clear
the inside edge or is more than the specified
amount, the offset must be corrected.

Yet, the measurement in the manual is 1.655" for the M series sleds. I think this is supposed to be measured from the back (engine side) of the primary fixed sheave to the front of the alignment bar?

Is this correct?

mountain sleds running wide open down the trail= blown belts. probably not an alignment problem at all, have seen sooooooooo many mt. sleds grenade belts with people thinking they are lake racers....

I agree with you

Truth is I was testing a new clutch setup, and due to out lack of snow, thats the best I could find!

I didnt have any problems last year, I just thought it would be good to check

Pray for snow

simple secondary fix for cats

quite simple to fix these secondary Cat woes
I changed it to a 11" STM old style cat clutch, the belt issues are simply gone! costs a few dollars however, I keep it with me from sled to sled
its on my 2009 M8 162 SP right now, I plan on putting it on my 2010 when i decide on getting one!
BTW my sled with a 162" goes 90mph on the lake! LOL

What does being a mountain sled have to do with running down the trail fast? The motor and clutches don't know the difference if you are on a lake or on a trail? The track maybe, but the engine and clutches? Not.......

mountain sleds have lower gearing. Some where between 80 and 90 mph your clutches will be fully shifted out and any more speed will result in the belt being pulled into the bottom of the secondary and belt failure. If you want to do 90 down the trail youll have to gear up

This is the first time doing this on a M con somone confirm this is correct ?
