Assembly of the Reverse Valve
1. Coat a new Reverse Valve O-ring (6) with O-ring lubricant and
install it in the groove on the Reverse Valve (10).
2. Install the Reverse Valve in the reverse valve bushing with the
slotted end trailing, making sure that the index mark on the
Reverse Valve is aligned with the index mark on the Bushing. See
Dwg. TPD2024-1.
(Dwg. TPD2024-1)
The Reverse Valve must be installed and indexed with the
bushing as directed in Step 2 and Dwg. TPD2024. Failure to do so
will cause improper operation of the Reverse Valve.
3. Insert the Reverse Lever (8) into the Handle (1).
4. Slide the Reverse Lever Spring (7) over the shaft of the Reverse
Lever and secure the Spring and Reverse Lever by installing the
Reverse Lever Snap Ring (9) in the groove in the shaft of the
Reverse Lever. Rotate the Reverse Lever so that it is pointing
to the symbol for FORWARD (clockwise) operation. See Dwg.
TPD2024-1.

1. Coat the Hammers (39) with a light film of Ingersoll Rand No. 170
Grease.
2. Replace the Hammers in the Hammer Frame (37) exactly as they
were when you marked them prior to disassembly.
If you are installing new Hammers or want to change the location
of the existing Hammers to utilize both impacting surfaces, slide
the Hammers in the Hammer Frame so that the half-round notch
on one Hammer is located on one side of the Frame and the half-
round notch on the other Hammer is located on the other side
of the Frame. These Hammers must be installed with the wide
bevels facing the web of the Hammer Frame as illustrated.
3. Replace the Hammer Pins (38).
4. Examine the base of the Anvil (40) and note its contour. While
looking down through the Hammer Frame, swing the top
Hammer to its full extreme one way or another until you can
match the contour of the Anvil. Enter the Anvil into the Hammer
Frame and through the first Hammer. Swing the bottom Hammer
in the opposite direction from the top Hammer and maneuver
the Anvil slightly until it drops into the bottom Hammer.
