STEP 8
Remove the allan screw from the side of the motor housing. You
will need to use your .035” allan wrench (20115A). Once again,
unscrew the screw in a counterclockwise fashion.
STEP 9
After you remove the screw, take the drive ring retainer out of
the housing. Also remove the two narrow drive rings.
STEP 10
Insert your turbine raceway tool (00003) into the three
holes in the raceway. Unscrew the raceway from the
housing. If you cannot get the raceway to unscrew, put the
threads of the housing in a 9/16” collet. With the housing
securely held, insert the raceway tool into the raceway and
unscrew.
STEP 11
Remove the vent plug from the housing. Like all threads on this handpiece,
turn counterclockwise to unscrew. Once the plug is out, replace the o-ring
(404072) in the rear of the housing.
