what belt can i run from polaris that has a 11.25 c-c distance between clutches
i used a cat offset tool for setting my alignment. the spacer i had with the clutch is too big and i have about 1/4 of float to the outside towards the bellypan the clutch can go, but it doesnt use it. ive talked with quite a few clutch tuners and said i can leave it as it, the belt will keep the clutch where it needs to be and the clutch wont move out that way much if any.I am guessing this is on your cat/prox ? I would think if you can get your free play in the belt down to 1 1/4" you should be fine. I have never played with a cat secondary but if its anything like a team there's more then enough adjustment to close the secondary up. lay a strait edge across the top of the belt and see what your free play is. clutch off set is the most important thing , most of the time it can be check by leaving the bolt out of the secondary and run it on a stand slowly, let the track slow down without using the brake . the float is set by the belt moving on the clutch , move your shims around to have about 1/16"~1/8" of float in and out on the jack shaft once its centered.[/b]
im going to take a few of the shims out of the clutch now and see if that does it[/b]
yeah, that worries me about what kind of top end i will get out of it now. oh well, its a start. some day this week i'll go and look for shorter belts what will work.If anything, it will give a real good sarting ratio, with the belt being pushed up the secondary so far.[/b]
tomorrow i will try to get pics if time allows and i will post them up in this thread.prox700man, do you have any pictures of your new engine /sled? would be fun to see what you have been up to... :beerchug:[/b]
i didnt just switch clutches man, i put a 900cat in my pro x, so not just a simple clutch change.your cc distence should not change by swapping the driven clutch to a Comet. the center of the jackshaft has not moved. if you are getting 11.25" cc then something is wrong with your motor mounting technique, the engine is sitting counter-clockwise from true parallel. re-set the engine to get 11.5", it's easier with both clutches off the machine, just measure the center of the crank bolt to the center of the jackshaft. then use your Cat alignment tool to set the offset left and right. it most likely will have about 3/16" side to side slack unless you shim it up with washers. also, Cat secondaries are set-up for 1.375" belts, your Polaris primary is set for 1.438" belts. be carefull that your new secondary does not bottom out the helix at full shift. there are deeper cut helixes available that allow full shift with the wide belt, or you can re-shim your primary and run an after market belt that is 1.375" x 46.625". i had the problem of bottoming out helixes on my '00 XCR 800 with an Erlandson Trackmaster secondary, same as a Cat but modded for two springs. if the helix bottoms and you have a hand full of throttle, it will snap your belt like someone cut it with a hacksaw. i broke about 10 before figuring it out.[/b]
