Description: Naraku Brand Premium CVT Drive Belt size 788x18x30 is made in Taiwan, not China's version. Its material used is Nylon previously used in making bullet-proof vests. Nylon strong yet it's flexible, not harsh on aluminum drive face like "Kevlar" which are recommended for heavier duty off-road applications. Nylon makes it gentle on CVT recommended for everyday riding use. Standard fit for 139QMB 50cc 4-stroke ATVs and Street Scooters with 12 or 13-inch rear wheel extra longcase engine.

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 existing variator fan, washer, and hand-tight nut. 4. Finally, apply blue Loctitetorque nut to 30-35ft lbs. For reassurance please consult your manufacturer variator torque specs.

NOTE: How tell if you have 139QMB longcase or shortcase? If the distance from variator nut to clutch bell nut is 8.75", then it takes a 669-CVT belt which makes it a shortcase. If the distance from variator nut to clutch bell nut is 10", then it takes a 729-CVT belt which makes it a longcase. For we can’t always tell by rim size alone, for example if the 139QMB Scooter has a 10" rim it can be tire size 3.50-10 (use 669-CVT belt shortcase) or have a tire size 130/90-10 (use 729-CVT belt longcase).
