Tuner Bushing Press Instructions

All in one bushing installer and remover



i-0460 Updated 12/11

Before installing bushings in the peghead on a new instrument, it's best to test your bushing fit in a piece of scrap to make sure that your reamed hole is not so tight that it will crack the overlay or possibly the peghead.

Prepare the tool for installation:



Use the brass tip with the smaller step on the end for pressing. Screw it into the brass side. Gently tighten using the provided Allen wrench, through the hole in the base of the pin. Add the protective rubber washer.

Screw in the flat threaded plastic anvil into the plastic side.


1. Set the bushing into the peghole and insert the small end of the pressing pin into the bushing. Position the anvil on the back of the peghead directly over the tuner hole.

2. Turn the adjusting knob until a gentle pressure is applied to the bushing. You should be able to lock the pliers at this point without pressing the bushing in at all.

3. While holding the press in one hand turn the adjusting knob a little and squeeze the pliers shut. Don't turn the knob more than a quarter-turn at a time. This gives you more control and a better feel of the pressure being applied. This control of the pressing action is key to avoid cracking or chipping the lacquer around the bushing. Continue to alternate turning the adjusting knob and pressing until the bushing contacts the peghead surface. As soon as the underside of the bushing touches the peghead surface, STOP.

4. Loosen the adjusting knob. Repeat for each bushing.



Prepare the tool for removing bushings:



If the tuner hole is the same diameter completely through the peghead, then attach the stepped brass pin used for installation. If the tuner hole is counterbored, then use the brass expanding pin.

Screw in the appropriate brass pin and tighten with the Allen wrench. Add the protective washer.

Included is a clear acrylic caul with three different sized holes in it that helps prevent denting the finish or wood around the bushing, also minimizes cracking or chipping that can occur during bushing removal.

1. Choose the hole in the bushing caul that matches the bushing (each hole is different, so you can get a close fit). Lay it between the Bushing Press' clear sleeve and the peghead.

2. Insert the expansion pin into the back side of the tuner hole and up through the bushing until the screw head is just below the bushing (illustrated). Tighten the Allen screw, expanding the pin, until it is snug inside the bushing. You don't want this pin to slip while pressing out the bushing, but don't overtighten either. Using the expanding pin takes a bit of finesse.


3. With the expanding pin tightened in the bushing, lower the clear sleeve of the press over the bushing by closing the press, and adjust the knob until only light pressure is applied to the bushing.

4. Adjust the knob no more than a quarter-turn at a time between pressing, for greater control and feel as the bushing is being pressed out. Continue to alternate pressing and adjusting until the bushing is out.

5. Loosen the Allen screw to remove the press from the bushing.


Removing stubborn bushings



Sometimes the bushings are so tight in the peghead that the expanding pin will not be able to push them out simply by the internal gripping. In those cases, the bushings can usually be removed by getting the expansion pin UNDER the bottom edge of the bushing and expanding it there. That way, it is not depending on gripping friction, but the fact that the expanded pin diameter is larger than the bushing hole.

Most of the time there is a gap between the bottom of the bushing and the step of the hole.

Expand the pin inside the bushing just enough to feel friction when sliding, but not enough to prevent it from sliding. Slide the pin downwards until you feel the end of the pin click free of the bushing. Push back up lightly until you feel the bottom of the bushing, and tighten the expanding screw a quarter-turn.

The pin only needs to be a few thousandths of an inch larger than the bushing, just enough to keep the expanded pin from going through the bushing hole. Now press the bushing out as per the previous pages instructions.
