Clutch Maintenance - Polaris 2003 Pro X Service Manual

CLUTCHING
MAINTENANCE
The driven clutch operates in conjunction with the drive clutch. Its function is to maintain drive belt tension pre-
venting slippage, and sense variations in load requirements necessary to maintain optimum engine torque output
and load requirements from the track. Output torque is transmitted through the chaincase jackshaft and chain-
case to the front drive shaft and track.
When the load on the driven clutch is increased and becomes greater than the torque delivered from the engine,
the driven clutch becomes dominant and overrides the drive clutch. The driven clutch downshifts into a ratio which
will match the increased load.
Because the driven clutch can sense and shift into the proper ratio, engine RPM will remain within the specified
range.
Driven Clutch Adjustments
The driven clutch has a provision for varying the torque required to change its ratio. It can be readjusted by relocat-
ing the spring in the helix which in turn increases or decreases the amount of load required to change the ratio.
