The Arctic Cat Crossfire/M Jaguar 06 sheave adjuster is a CVT component used to fine-tune belt deflection on 2006-era snowmobiles, including Crossfire 600 and 1000, F1000, F5, F6, F8, and Jaguar models. To set belt deflection, remove the adjuster from the driven pulley and add or remove shim washers—Arctic Cat part numbers 0648-714 (0.090 in), 0648-715 (0.030 in), and 0648-716 (0.060 in)—as needed. This adjuster is referenced in Arctic Cat service notes for correcting drive belt deflection on Crossfire 600/M6 models and is part of the standard toolkit for tuning clutch performance on these 2006-era machines.
