Proper clutch alignment is very important for belt life and performance. The standard procedure is to align the clutches with a small amount of misalignment or skew at zero load and hope when under load the motor is pulled into the correct alignment. This procedure worked okay for years but many things have changed, sleds have more torque and motor mounts have been changed to reduce vibration.
On the Ski-Doo Gen4 REV models the secondary clutch is almost directly over the primary clutch, actually pulling the motor up when under load. The old alignment procedure of using a standard amount of skew at zero load isn’t working well, so here is a better way to align your clutches using the new Clutch Preloader from Grip n Rip Racing.
The Clutch Preloader does what the name indicates – it places a load between the clutches to simulate where your clutches are positioned in different riding conditions. This allows you to measure clutch alignment under a simulated load to see what your actual alignment is. What you will find is that your clutches are not in alignment when under load. This is one of the reasons you are getting so much heat and blowing belts. With this information you can shim the motor mounts to improve alignment, reduce heat, slippage and increase performance.
