i am new to this but have a question about aaen roller clutch. i have a 2003 scrambler 500 and recently purchased a roller clutch and hsp clutch kit. i set it on 2-2 like it said and results were horrible. i took it apart and redid the pretension and again terrible. i called hsp and aaen and they said it should be fine set there. what happens if you set it at 2-5 or 1-5. i am looking for a good combo for trail riding and hill climbing and just all out torque. set at 2-2 it smoked the belt just trying to load in my truck from dead stop i ahd to get a run at it. please anybody with some answers please reply. thanks

 

Sounds like you didnt preload it right.2-2 should have been great.

 

If you smoked the belt just getting in your truck, then I would agree that the preload is not set right. How close is your dealer and how good are they? If they are a good dealer, then just take it to them and have them preload it. It should only take them a minute

 

I'm with these other guys. Either you preloaded it backwards or not enough. I'm pretty familiar with the PVT and preloaded mine backwards twice myself before I got it right. It should be a great upgrade not a horrible one.

 

thanks for the advice will give another try. have question what would be the differnce in say a 2-5 setting and a 2-2. what happenens when you give the secondary more pretension. does this may it more suitable say for slow hill climbs or crawling around on rocks?

 

anybody please.

 

it will engage at a higher rpm, on the snowmobile spring needs to pretension by a 1/4 turn and hole 1 too 4 will increase engagement by 250 rpm.so I asume it should be about the same on a atv with the same type clutch.and for belt tension is adjusted by shimiing the sheaves closer together or further apart, this controls bite on the belt. you need all the specs for the atv clutch you need to know center to center and offset and belt deflection.all info can be found in a service manual. there is alot to learn to proper set up a clutch.

 

Engagement is dictated by the spring in the drive clutch not the preload of the secondary clutch. A little more preload in the secondary will slow the upshift thus causing higher rpm for a given speed. HOWEVER, secondary preload should be set with a spring scale (the hole's numbers are only for reference to use with a scale) within the recommended range and not set outside that range as an "adjustment". If proper secondary operation can't be achieved within the recommended preload range, then it's time to change the helix.
