Step 3: Install Bearing:
•
Push the handpiece bearing into the frame
bore and align the bearing flat with the
frame flat.
•
The bearing should go in with minimal
effort and not require pressing.
•
Do not force the bearing in. If the bearing
does not go in easily, check frame and
bearing for damage or build-up.
Step 4: Install Pinion:
•
Insert the pinion into the bearing bore.
•
The pinion should go in with minimal effort and
not require pressing.
•
Do not force the pinion into the bearing. If the
pinion does not go in easily, check the bearing
and pinion for damage or build-up.
•
The pinion should sit flush against the bearing.
If it does not, rotate the pinion to seat it flush
with the bearing.
