Extra Details

Note: New pump has a smaller flywheel. Must change motor pulley and belt due to K Breaker Pump having a 10.375" flywheel. Email us your current motor HP, RPMs, and shaft diameter in order for us to calculate the properly sized pulley.

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).
