How to Set Polaris RZR 900XP Cam Chain Timing 

Cam timing that's off by just a fraction means your side-by-side will not perform the way it should.

Make sure you set your Polaris RZR 900 cam chain timing correctly when servicing your engine. Here’s how to do it in 7 simple steps.

Tools Needed - Polaris RZR Cam Chain Timing 

  • Ratchet and extension
  • 8mm, 27mm sockets
  • Torque wrench
  • Polaris cam tool

NOTE: The Polaris cam tool is a special order tool that you need to call Partzilla at 877-473-4549 to order. The part # for the Polaris cam tool is PU-50563-1.

Setting Polaris RZR 900XP Cam Chain Timing

Step 1. Hold the camshafts in position using the Polaris cam tool. The camshafts will need to remain held in position for the timing to be set correctly. You may have to use a wrench to position the intake camshaft so the Polaris cam tool slides into the camshaft slot.

Step 2. First, set the timing on the intake cam. The letter "I" is imprinted on the intake cam sprocket. To set the timing position, place the intake sprocket so that its two timing marks are level with the cylinder head. Once the sprocket is correctly set, lay the timing chain over it and install the timing sprocket mounting bolt into the bolt hole that's visible, then torque it to 14 foot-pounds.

Step 3. Set the timing on the exhaust cam. The exhaust cam sprocket has the letter "E" imprinted on it. To set the timing, repeat the process outlined in Step 2.

Step 4. Remove the Polaris cam tool, and rotate the timing sprockets until the other two bolt holes are visible (one on each sprocket). Install the remaining timing sprocket mounting bolts and torque them to 14 foot-pounds.

Step 5. Put some assembly lube on the camshaft carrier and the camshaft journals, and install the camshaft carrier. Next, install the upper cam chain guide on top of the camshaft carrier.

Step 6. Torque down all the camshaft bolts to 89 inch-pounds. The bolts must be torqued in a specific order so that the pressure on the camshafts is applied evenly and won't damage them. You can see the correct order in the image below.

Step 7. Reinstall the cam chain tensioner, torque it to 29.5 foot-pounds and you're all set!
