Bando CVT Belt 743-20-30 Kevlar (GY6 shortcase)
Description: Bando Brand Premium Kevlar CVT Drive Belt size 743-20-30 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 743-20-30 commonly found on GY6 125/150cc 4-stroke ATVs and Street Scooters with a 10-inch rear wheel shortcase 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: 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 which uses a 743-CVT belt, here.
