The Reverse Button (left) (33) must be pushed in
before the Trigger can be installed. Otherwise, the
Trigger will be damaged during installation.
4. Install the Trigger by pushing it into the handle until a
click is heard indicating that it is properly engaged.
Assembly of the Motor
When disassembling, assembling or pulling the
Motor, we recommend replacement of the Motor
Gasket (7).
1. Install the Motor Gasket in the Housing making sure
that the grooves in the tab of the Motor Gasket fit
around ridge in the Housing. See Dwg. TPD1336.
2. Install the Rear Rotor Bearing (3A) into the rear of
the Cylinder (1).
3. Install the Rotor in the Cylinder and secure with the
Rear Rotor Bearing Retainer (6).
4. Install Vanes (4) in the slots in the Rotor (5).
5. Install the Front Rotor Bearing (3) into the Front End
Plate (2). Install the Front End Plate on the Cylinder
by pressing on the inner race of the front Rotor
Bearing until the Bearing is seated on the Rotor Shaft.
6. Install the Power Management Dial (34) through the
front of Housing into smaller diameter at rear.
Position the Dial so that the arrow lines up with one
of the power setting indicators. Install the Dial Seal
(35) at the beginning of the same diameter.
7. Insert the motor assembly into the front of the
Housing so that the smaller diameter at the rear of the
motor will seat the Dial Seal when the motor is
pushed into it's final location.

Pneumatic Grease.
3. Replace the Hammers in the Hammer Frame (12)
exactly as they were when you marked them prior to
disassembly.
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. See Dwg. TPD1535.
Assembly of the Air Wrench
1. Position the Motor Housing (19) in leather–covered
vise jaws with the splined shaft of the Rotor in a
horizontal position.
2. Place the assembled impact mechanism down onto
the splined hub of the Rotor.
3. Position the Hammer Case Gasket (18) against the
face of the Motor Housing.
Be sure that the flat on the bottom of the Hammer
Case Gasket is installed in the corresponding flat in
the Housing. If the Hammer Case Gasket is not
installed correctly, the Air Wrench will not
function properly.
See Dwg. TPD1335–1.
4. Apply a thin film of Mac Tool Pneumatic Grease on
inside surface of the Hammer Case Bushing (16), and
place the Hammer Case (15) down over the Anvil and
against the Motor Housing.
