11. Using finger pressure, compress the Springs with the
Blades until the outer edges of the Blades are flush
with the drive shaft surface. Capture the Blades in this
position by installing the Liner Assembly, piston stop
end trailing, over the Drive Shaft and against the Rear
Liner Cover.
This installation can be accomplished more easily
by aligning the compressed Blades with the webs at
the narrowest portion of the opening. Keeping the
Blades on the web allows them to slide the length of
the Liner without interference.
12. Insert the hex end of the Rear Liner Cover into the
Disassembly Arbor from the Tool Kit and stand it on a
workbench with the Drive Shaft upward.
13. Install the Front Liner Cover Assembly over the Drive
Shaft and against the Liner. Make certain the Torque
Adjustment Screw (53) aligns with the proper piston
stop opening that was marked during assembly.
14. Install the two Liner Cover Seals (62) in the grooves
inside the Liner Housing (51) near the end with the
external wrench flats.
15. Place the Liner Housing, Seal end trailing, over the
assembled Liner. Make certain the notch in the
trailing end face of the Housing aligns with the Oil
Plug (56) in the Front Liner Cover. Use the Pressing
Sleeve from the Tool Kit to press the Housing over
the Seals and into position. Do not Damage the Seals
during installation.
16. Grasp the flats of the Liner Housing in vise jaws and
using the Spanner Plug furnished with the Tool Kit
and a torque wrench, install the Housing Cap,
castellated end leading. This is a left–hand thread;
rotate the wrench counterclockwise to tighten the
Cap. Tighten the Cap on model 1100P or 1410P
between 137 and 152 ft–lb (186 and 206 Nm) torque
and on model 1900P between 173 and 188 ft–lb
(235 and 255 Nm) torque.
17. Make certain the Drive Shaft rotates freely and then
fill the mechanism with fluid and reassemble the tool
as instructed in the section, CHANGING THE
MECHANISM FLUID.
MAINTENANCE SECTION
18. After assembling the tool, check the torque output
21
with a torque tester or pulse counter.
If the output is not acceptable, adjust the torque
output as instructed in the section TORQUE
ADJUSTMENT on Page 2.
If the output is acceptable, proceed as follows:
a. Using a hex wrench, remove the three Hammer
Case Cap Screws (43) and Lock Washers (44). Lift
the Hammer Case (39) off the Motor Housing (1)
over the Drive Shaft. Remove the Hammer Case
Gasket (42).
b. Lift the assembled mechanism off the Rotor (28).
c. Grasp the flats of the Housing (51) in vise jaws
with the output end of the Drive Shaft downward.
d. Insert the pins of the Spanner Plug from the
No. 700A–99 or No. 1900P–99 Tool Kit into two
holes in the Housing Cap (76). Using a wrench on
the plug, unscrew and remove the Housing Cap
from the Housing. This is a left–hand thread,
rotate the plug counterclockwise to loosen the
Cap.
e. Apply thread sealant to the threads of the Cap and
using the Spanner Plug furnished with the Tool Kit
and a torque wrench, install the Housing Cap,
castellated end leading. This is a left–hand
thread; rotate the wrench counterclockwise to
tighten the Cap. Tighten the Cap on model
1100P or 1410P between 137 and 152 ft–lb
(186 and 206 Nm) torque and on model 1900P
between 173 and 188 ft–lb (235 and 255 Nm)
torque.
f. Position a new Hammer Case Gasket (42) on the
Motor Housing and install the assembled
mechanism on the rotor shaft.
g. Place the Hammer Case Cover over the Drive
Shaft against the Housing and Gasket. Install the
three Hammer Case Cap Screws and Lock
Washers. Tighten each Screw between 45 and
50 in–lb (5.1 and 5.6 Nm) torque.
h. Install the Rubber Housing Boot on the tool.
