Drive clutch belt clearance
Dan,
Any pointers/tricks to performing proper belt clearance adjustment on the primary over and above the service manuals instructions??
Thanks in advance,
Glen
Glen, my main concern,.
If your a crazy weight changer and you jump around to all different brands of drive clutch weights then the belt clearance has to be checked EVERY time you jump ship.
My advice to the novice clutch tuner..........pick a brand of clutch weight and STAY with it............if this surprises you then your a novice.
If you check and adjust your belt clearance everytime you change weights then you are no average tuner.
changing styles and brand clutch weights in high HP sleds is for EXPERTS ONLY!!!!!
800 cc and above you should stay with OEM weights period. ( unless your an expert ).
My prefered drive clutch belt clearance is ZERO to a brand new belt ( the belt I am going to be running NOT one with the same part number ) belt runs vary in width and length.
I shim to the narrowest part of the belt I can find then I do NOT let the sled idle until the belt is broke -in and wide part is woren off.
And scrub your belts in HOT soapy water with a brass brush until it starts to look alittle white and all the loose black compound is gone.
If you have never scrubbed a belt, You should try it and see how much better then work and last ( AND ) how much cleaner your clutches stay.
I have said this same thing many times.
Best to do a search and see if you can find clutch threads and read them.
with todays high HP sleds, 95% of the people are totally in the dark about belt care and clutch set-up.
And, if you have ever blowne a belt on a sled your clutch set-up is either wrong or your running the belt to many miles.
If a belt is Blowen on one of my torque master bottom-ends I will know it the second I take it apart and the warranty will be void.
When you blow a belt on a 800 at WOT or close to wide open throttle the crank flexs and the center seal hub hits the case and the crank is most likely now bent.
You heard me right, if you blow a belt on an 800 Polaris it most likely is now bent.
Engine heat soaking & Drive clutch set-up and belt care are the most things you can do to todays high output motors.
