Replacing the Head
When the Head Should Be Replaced
The head is an expendable item that eventually will wear out
and need to be replaced. Replace the head when the following
occurs:
• The head surface is torn
• Striking points are no longer detected correctly, even
when the head tension is properly adjusted.
• Slack portions remain in the head even after the head
tension is properly adjusted.

MH-8 Mesh Head: for either PD-80 or PD-80R
Replacing the Head
1.
Remove all tuning bolts and washers.
If using the PD-80R, press the lock bushing (in figure
below) in place with your finger as you remove each
tuning bolt, to prevent the bushings from being pulled off
the frame.
fig.P05.e
For more on the lock bushings, refer to the following section,
“About the PD-80R's Lock Bushings.”
2.
Remove the hoop.
3.
Remove the old head.
4.
Place the new head on the frame.
5.
Place the hoop onto the head.
6.
Pass the tuning bolts through the washers,
then attach them to the hoop and frame.
7.
Next, adjust the tension of the head. Refer to
“Adjusting the Head Tension” (p. 5).
Do not firmly tighten a single tuning bolt by itself. Doing so
will make it impossible to tension the head evenly, and will
cause malfunctions such as failure to accurately detect the
striking location.
About the PD-80R's Lock Bushings
The PD-80R is provided with lock bushings to prevent rotation
and loosening of the tuning bolts caused by vibration
transmitted from the hoop, as the result of using rim shots or
other performance techniques.
If a lock bushing happens to become separated from the frame
while the head is being replaced, position the bushing so its
four slots are aligned with the corresponding ridges in the
frame, then press down firmly on the bushing.
