NCY Secondary Sliding Sheave Assembly (Honda Dio)
Description: NCY Secondary Sliding Sheave Assembly for Honda DIO 50cc-90cc scooter engines. This NCY adjustable secondary sliding sheave has two sets of ramp angles, one steeper than the other. These allow you to adjust how quickly the pulley engages. A quicker engagement means more power off the line, and more gradual engagement gives you more power at speed
NOTE: 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. 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 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.
