Ang hur sekundärvariatorn ska ligga förhållande till primären så har TRS från snowest tagit fram lämpliga mått som fungerar.

"We are finding to many variables in clutch alignment tools to get an accurate or a proper base setting for our mountain sleds.
There are major variations regarding the factory set lead in. Most of these variables cannot be adjusted out to get within the factory spec. regardless if it’s a 800 or 850 chassis.
We use an SLP bar to set our base measurements, and sadly they are no longer available. Belt life is what we strive for and is very relative to offset.
What we have found for an offset measurement, that enhances belt life on our clutch setups, doesn’t mirror the factory recommendation.
There is an easy method to accomplish offset. You will need a piece of 1/4” key stock, digital caliper, and jackshaft spacers along with float washers. Spacers and washers are available from your Polaris dealer.
Remove your belt and bridge the key stock across the backside of your primary. With your caliper measure from the key stock to the outside leading edge of your secondary. The measurement we have found that works is
Axys 850: 2.57”
Axys 800: 2.60”
You will find most sleds will need around .100” added to the shim stack.
Once you get it shimmed to this spec you can adjust float. We float the secondary outward .015-.030”. Over float causes undue belt wear. Carbon fiber belts start to stress, somewhat, around .030” of misalignment.
These measurements have been working very well for us. You can fine tune your offset, in or out, by learning how to read your witness marks on your belt. Each sled and riders belt wear pattern will be a little different in this respect. Gearing, motor mount wear, NA, turbo and other factors contribute.
I wish you all the best in belt retention.
EDIT: Thanks Tewstroke
This is for a non-ES clutch. Adjust your measurement accordingly.
Remove after market torque arms when using this method. "
