Assembly of the Impact Mechanism
1. Coat Hammers (48) with grease and place the two together
so that the faces having the partial recess in the central
opening contact each other and the half notch in the edge of
one Hammer aligns with the wide notch in edge of the other
Hammer.
If you are installing new Hammers or want to change the
location of 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.
2. Slide the two Hammers into Hammer Frame (46).
3. Capture the Hammers inside Frame by installing two Hammer
Pins (47) in end of the Frame opposite the hub with the internal
spline.
4. Insert Anvil (49) into end of Hammer Frame opposite hub with
internal spline until it seats. It may be necessary to rotate the
Anvil while moving the Hammers. Anvil is properly positioned
when Hammers are displaced whenever the Anvil is rotated.
