 selectable pulley ratio Explanation:A text dealing with pulley ratios: Finding Pulley Ratio (The correct pulley ratio is very important for correct alternator performance) 1. A pulley ratio of 3 to 1 is preferred, or a ratio as close to 3 to 1 as possible. It is recommended not to use a ratio less than 2.5 to 1. 2: To find the pulley ratio: Measure the diameter of the crankshaft pulley (or the pulley driving the alternator) and the diameter of the alternator pulley. Note: Measure V belt pulleys on total outside diameter. Measure serpentine belt pulleys across the top of the grooves the belt rides on. 3. Divide the diameter of the crankshaft pulley by the diameter of the alternator pulley. This will give you the pulley ratio. 4. The power curves show alternator RPM . You must multiply engine RPM by the ratio to get alternator speed. http://www.e-marine-inc.com/products/alternators/pulley.html

Finding Pulley Ratio
(The correct pulley ratio is very important for correct alternator performance)

1. A pulley ratio of 3 to 1 is preferred, or a ratio as close to 3 to 1 as possible. It is recommended not to use a ratio less than 2.5 to 1.
2: To find the pulley ratio: Measure the diameter of the crankshaft pulley (or the pulley driving the alternator) and the diameter of the alternator pulley.
Note: Measure V belt pulleys on total outside diameter.
Measure serpentine belt pulleys across the top of the grooves the belt rides on.
3. Divide the diameter of the crankshaft pulley by the diameter of the alternator pulley. This will give you the pulley ratio.
4. The power curves show alternator RPM . You must multiply engine RPM by the ratio to get alternator speed.
