Malossi Variator Boss 20mm (Honda Dio)

Malossi Variator Boss 20mm (Honda Dio)

Description: Malossi Variator Boss Stainless Steel length 35.7mm x outer diameter 20mm x inner diameter 14mm for Honda DIO 49/50cc scooter engine. 

NOTE: THIS IS NOT FOR EARLY MODEL (PRE-1994) AF05E Engines. 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. For Honda DIO require belt-size 654-18-30 (Part# BD44DIO-6541830).

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.
