Note:This is the Same as the 240-872, Except This Unit Uses the Later Rotor Shaft and Larger Rear Bearing. The 7685, Fit With a Smaller Diameter Pulley, Becomes the 8022 (160A). Output is Determined By the Correct Pulley Being Used.The 22SI Unit With Specs Virtually the Same as This 21SI Unit is the 8078 (240-4017A). 22SI Units Have Improved Physical Characteristics Over the 21SI, as Well as the Autostart Trio Feature Not Used in the 21SI. This Should Be Considered if Using the 22SI In Place of the 21SI. The Vset on this unit is 14.1 . Same with 14.5 Vset see 240-861C | The 7685, Fit With a Smaller Diameter Pulley, Becomes the 8022 (160A).
