Stage6 Secondary Sliding Sheave R/T Oversize Torque Boost Assembly (Aprilia, Piaggio, Vespa 50)

Stage6 Secondary Sliding Sheave R/T Oversize Torque Boost Assembly (Aprilia, Piaggio, Vespa 50)

Description: Stage6 Secondary Sliding Sheave R/T Oversize Torque Boost Assembly for Aprilia, Piaggio 50, Vespa 2-stroke engines. The Stage6 Oversize CVT. Different from conventional torque drivers that are manufactured from steel, this part consists of forged aluminum halves that are screwed to a guide piece. The halves have been CNC-machined, which guarantees high precision, especially of the surface angle. Special attention has been paid to ensuring an ideal surface roughness, as this has major influences on shifting characteristics. At the end of the manufacturing process, the surface structure is protected by applying a thick ceramic coating, so that the surface characteristics can be preserved as long as possible. Advantages of modular construction include reduced heat built-up, the noticeably lower weight, and the possibility to replace individual worn components. The CVT uses a guide piece with 38/41

NOTE: Recommend using a new belt with this kit. The belt and the belt drive-facing plates KEEP DRY. All, other areas apply moly-graphite grease when assembling. For example, lubricate slider grooves, slider pins, ball bearing seat, and inner funnel area with heat-resistant moly-graphite grease.

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 giving 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.
