Grease or Ingersoll–Rand No. 105–8LB Grease to the
jaws of the Anvil (8).
3. Replace the Hammers in the Hammer Frame (12)
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.
4. Replace the Hammer Pins (13).
5. Examine the base of the Anvil (8) 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. Refer to Dwg. TPD1535.
