The ratio between the crankshaft of the engine to the transmission is a constantly variable belt drive - the actual ratio is not published but in therory it is 0 at idle and 1:1 at full throttle and at maximum speed. The 'transfer case', is a transmission and there is a fixed gear reduction with the choice being low range, high range and reverse and I do not know the overall reduction of the gear box to the final drive or what the reduction to the tire surface would be.Hi Everyone,
I am trying to mod a Sportsman (most likely 500) to drive off of an electric system. However, I am hovering above a few options of motors. I just wanted to know, what is the approximate gear ratio between shaft that exits the engine to the shaft that enters the transfer case? Is it a larger gear on the transfer case and a smaller one on the engine, or vice versa, or are they the same? Also, when they say for example, the engine has a power of 44 horsepower, is that coming directly out of the engine or at the wheels?
The power is typically BHP at the rear wheels the engine probably has appx 15 to 20 crankshaft HP, but that depends on RPM.
