When adjusting the belt deflection and ride height of the drive belt on most of the new Arctic Cats fitted with the ACT drive, you need to add or subtract shims to the external adjuster at the end of the shaft. Problem is, if you want to tighten the belt or get it higher in the secondary, you will need some more shims.
Here are the part numbers for the shims that are offered in three thicknesses. Part # 0648-714 is for the 0.090â€ shims. Part # 0648-715 is for the 0.030â€ shims, and part # 0648-716 is for the 0.060 shims. They’re all priced at $0.89 to $0.99 each, so order several of each size for your clutch tuning and belt fit purposes.
