Fitting Pin Drive Pin
The pin drive pin is tapered, identify the small end of the broken pin and tap this small end of
the pin with a punch to remove it. Tap in the new pin gently, don’t hit it hard or you will crack
the end of the shaft. Place the big end of your pin on an anvil or something solid and round
off (or burr over) the small end of the pin ensuring it is a good fit into the shaft, finish this job
by filing the small end flush with the shaft. Make sure the big end does not protrude out past
the outer rim of the drive coupling, if it does this will rub on the tube and run hot, file off the
excess.
Adjust Centrepost using a Post Guide
The post has a notch in the bottom around from the screwdriver slot (Illustration 16). Use this
notch as a setting mark and once you have the handpiece cutting well remember or write
down where this mark is, this will enable you to reset the post to the original position should
the need arise.
