Description: The starter clutch aka starter bendix creates the link between the starter and the crankshaft and is a common problem for starting issues on a 139QMB 50cc engine. Crunching and knocking when starting often point towards a problem with the starter bendix. Leaving it could cause major damage to the engine cases.

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 Loctitetorque nut to 30-35ft-lbs. For reassurance please consult your manufacturer's variator torque specs.

NOTE: The Naraku Drive Face (Part# NK900.59), fan overlay, and kickstart star him (see Fig. 4) are not included only for placement demo. If required, please order separately. Recommendations: Use a new belt with this kit and graphite or moly grease when assembling.
