Is your Can-Am ATV or Side-by-Side's primary clutch making noise, slipping, or not engaging smoothly? This Caltric rebuild kit contains the most common wear items you need to freshen it up and restore performance. The kit includes 6 new Rollers, 6 Roller Sleeves, and 12 Shoe Sliders (the little pads on the clutch shoes). These parts get worn down over time from heat, dirt, and engagement forces, leading to poor shifting and power loss. This specific kit fits a HUGE range of Can-Am (Bombardier) models from the early 2000s up through recent years. We're talking the Outlander series (330, 400, 450, 500, 570, 650, 800, 1000), Renegade sport quads (500, 570, 800R, 850R, 1000), Commander and Defender utility vehicles, and even the Maverick Trail and X3. It's crucial to compare the parts in this kit (and the listed part numbers: Roller 420229585/417223767, Sleeve 420233890/417223257, Slider 420281290/420281296) to the worn parts you remove from your machine to ensure a perfect match. Rebuilding the primary clutch is a common maintenance task for experienced DIYers and can save you the high cost of a whole new clutch assembly.
