TWH Secondary Sliding Sheave Assembly (Honda Dio)

TWH Secondary Sliding Sheave Assembly (Honda Dio)

Description: TWH Secondary Sliding Sheave Assembly for Honda DIO 50cc-90cc scooter engines. This adjustable secondary slider plus sliding sheave from TFC will give you quicker takeoff and higher top speed. The 2 different linear options mean you can give more emphasis to acceleration.

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.

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.
