Chaincase Gearing (if equipped)

A speed sensor reads the speed of the brake disc on the jackshaft. The engine management system uses this signal to determine vehicle speed.

If changes are made to either the upper or lower chaincase sprocket, the engine management system must be updated to set the new drive ratio. Please see your POLARIS dealer to reprogram the speedometer offset calibration if you install different chaincase sprockets.
