NCY Drive Face CNC-Machined +Star Him (139QMB)
Description: NCY Drive Face CNC-Machined aluminum plus kickstart star him for 139QMB 49cc-50cc scooter engines. This set allows you to mount the original variator fan overlay and use NCY kickstart star him. The CNC-machined running surface of the disc allows for a clean, low-vibration belt operation.
NOTE: Must use existing variator fan overlay, washers, and nuts - not included. If required, please order separately. Recommend using a new belt with this kit. Belt and the belt drive facing plates KEEP DRY. All, other areas apply moly-graphite grease when assembling.
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 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 variator torque specs.
