MAINTENANCE SECTION

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 exisiting 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.

5.

Set assembled hammer mechanism onto rotor shaft
spline.

6.

Place Hammer Case Gasket (41) over mechanism and
against face of Motor Housing.

7.

Grease Anvil and top of the Hammer Frame.

8.

Place the Hammer Case (39) over the mechanism
assembly against Gasket.

9.

Assemble Dead Handle (50) to Dead Handle Bracket
(51). Insert two Hammer Case Cap Screws (42) with
Lock Washers (43) through Bracket and install  two
Dead Handle Bracket Spacers (52) on the Screws.
Position the assembly against Hammer Case and
thread Screws into Housing.

10. Thread remaining two Cap Screws and Lock Washers

into Housing and using an alternating pattern for all
four fasteners, tighten Screws to between 20 and
25 ft–lb (27 and 34 Nm) torque.

11. Install a new Exhaust Silencer (30) in the Exhaust

Deflector (29) and then install Exhaust Baffle (31) in
Deflector.

12. Position a new Exhaust Gasket (32) against face of

Motor Housing. Position the assembled Deflector
against Gasket and secure it by tightening the two
Deflector Screws (33).
