Polini Clutch Spring Set (DIO, GET, QMB)

Description: Polini Clutch Spring Set. Clutch springs do a couple of things. First, they supply the pressure to engage the clutch. They also determine the rate at which the CVT transmission changes from low to high gear along assisting the compression spring. Polini clutch pressure springs use a modified alloy spring providing better resilience and above-average strength for 139QMB, Buddy50, RoughHouse, and many other 49/50cc base engines.

Installation: Make sure variator drive face is seated properly and not get its teeth chewed by the Bendix: 1. Slack the belt by opening the CVT clutch gives belt slack to the variator side. 2. Then install the variator drive face while lifting the slack belt further away from the center boss if done properly should not see any splines between variator drive face slop-side and boss flat-side. Should be flushed together. 3. Then install the existing variator fan, washer, and hand-tight nut. 4. Finally, apply blue Loctite, torque nut to 30-35ft-lbs. For reassurance please consult your manufacturer's variator torque specs.
