Bando CVT Belt 835-20-30 (GY6 longcase)
GY6 longcase length: 17-7/8 inches
Description: Bando Brand Premium Kevlar CVT Drive Belt size 835-20-30 is made in Japan, not China's version. Its material used is Aramid aka “Kevlar” which is used in making bullet-proof vests. Aramid characteristics reduce belt stretching and stress that can adversely affect the quality of belt engraving performance while preserving long belt life. Recommend for heavier duty off-road application. CVT Drive Belt size 835-20-30 commonly found on GY6 150cc 4-stroke ATVs and Street Scooters with 12 or 13-inch rear wheel longcase engine.
Installation: 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.
NOTE: If the distance from the center of the variator nut to the center of the clutch nut is 11", then you would use an 835 belt (most if not all Chinese long case 150cc engines). Another way to determine if you have a GY6 shortcase or longcase engine? If it has 10 bolts securing CVT cover and measures horizontal 17.875" across the CVT cover it a longcase which uses an 835-CVT belt. If it has 8 bolts securing CVT cover and measures horizontal 16.142" across the CVT cover its a shortcase that uses a 743-CVT belt.
