Rotary Head Repair Parts
A repair kit for this Whirl-a-Way's rotary head, is available.
If you encounter problems with the rotary head after the 1 year warranty
has expired, this repair kit (part #85.790.010) allows you to replace the inner
components very quickly.
The rotary head has a snap ring on the bottom holding all the bearings inside.
By removing the snap ring and washer, you can tap off the outer shell with a
hammer while the output shaft is held in a vice. The rotary head repair kit can
then be used to replace the worn items inside the rotary head shell.
