New flywheel size is 10.375" in diameter. If you have the larger 13.25" flywheel, determine the new pulley size for the motor by measuring the outside diameter (OD) of the existing pulley and multiply this number x .75 to come up with the correct new size.
Example:

4.25
x.75
3.1875" pulley (this can be rounded to the nearest pulley size, 3.25" or 3", for instance).

New Jenny K Pump Assembly

The Jenny K pump is a single-stage, splash-lubricated, inline twin-cylinder pump that is widely accepted as one of the best contractor pumps on the market. Used on Emglo-branded units for decades, Jenny, Inc. bought the original factory in PA but didn't change a thing. New name, same fantastic pump. Fully cast-iron with easily-replaceable spring-actuated disc valves, the K pump mates to a 3/4 HP (minimum) electric motor. It produces 8 CFM @ 100 PSI (2 HP electric). The pump comes complete with flywheel and air intake filter and if you ever need them, we have replacement parts available as well! The K pump has been replicated for years, but never duplicated. This pump does not have head unloaders. Maximum pressure output is 125 PSI. There is no harder working pump with the longevity expected from an industrial-grade pump than Jenny air compressor pumps.
