#1 Chain Drive Gear Ratios Explained

Details 

This is about wheel drive belts, chains and sprockets on dual belt or belt & chain models. The bigger the shaft sprocket, the more the torque or low end pulling power, while smaller provides more top speed. we offer 12 & 13 toothed hardened shaft sprockets. Wheel sprocket is the same principal. small=speed & large=torque/pull. Cobra & The Rock & Nuke are 20 tooth shaft/belt gear to 60 toothed wheel belt gear=ratio 1:3 which provides good speed on 9 inch tire. most other models are: 1:3.16 or 1:3.95 gear ratio which provides good torque. big wheel models are 1:5.1 select your factory or custom gear ratio by selecting 1 of 2 available #35 Chain Drive shaft/hub mount sprockets and many different wheel plate style sprockets. shaft sprockets have set screw, but must be welded to shaft after determining correct position & tracking. wheel sprockets are bolt on. call scooterman @ 256.468.2761 u.s.a. english for assistance in ordering custom chain drive.

Details 

585-5M-15 Belt for use with 24 tooth clutch sprockets Some Chuweng Raser or xcooter thunder THS Big Wheel scooters used this belt from factory with a 24 tooth trans sprocket. Reccomend 585-5m-15 belt if you are using a 24 tooth engine/trans 5m belt sprocket. The most common belt used for the left side or clutch belt with a 20 tooth engine sprocket and a 60 tooth shaft sprocket is a 575-5m-15. replacement of dry rotted twisted mis-shapen motor mounts can cause belt tension & alignment issues and incorrect length choice or misdiagnosis. your motor can be adjusted forward and backwards slightly to help with belt tension. we recommend replacing the motor mounts if the motor mounts are dry rotted or they stay twisted with the transmission belt removed.
