The crankshaft and the jackshaft must be parallel at all times. MAX. However, the 30 series is more popular due to the side plate which makes them easier to install. Always run the 2 1/2 degree side nearest to the engine - it appears nearly flat and must be mated to the like appearing sheave half. The drive belt will then be forced to a larger diamter within the clutch sheaves, thus pulling it to a smaller diameter within the driven unit sheaves. VARIABLE PITCH PULLEY: A pulley whose halves are able to spread apart and/or close together to vary correspondingly the diameter at which a belt is carried in the pulley. This is the only system designed to operate this way, thus providing the proper alignment for the final drive chain to be on the same side of the vehicle as the P.T.O. Copyright 2022 BMI Karts & Parts. Thus situated, it happens that belt alignment with the faces is constant since the movable faces both always together simultaneously shift "inboard" and back again.

Recommended Torque for bolt: 24 ft. lbs. 99. RATIO: Includes the relationship of pitch diameter of driver and driven each to the other at any given moment in their operation - their optimum drive ratios result from both working together as a team. The main differences between centrifugal clutches and torque converters are: Centrifugal clutches connect the engine to the transmission, while torque converters allow the engine and transmission to run independently from one another. Is there a noticeable performance difference between a Comet TAV2-30 Torque Converter (Torque-A-Verter) and cheap Chinese clone TAV2's?I put them both to the test in a series of unscientific real world challenges using 6.5hp gx200 clone, Baja Mini Bikes.

(Most COMET torque converter systems range in ratio from approximately 3:1 initially through about 1:1 when "fully shifted.") On a stock motor running at 3600 rpm you will not see much difference in performance, running 4000+ rpm is where the Juggernaut shines. Ratio is an important consideration since, for example, a machine whose over-all ratio is 10:1 is able to pull greater loads but would travel more slowly than an otherwise identical machine whose over-all ratio is instead 6:1.
