Requirements

If you are replacing an older pump not with serial number beginning with G, then you will need a new belt guard and belt. This pump is 1" taller to hold more oil.

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).
