If you continue to rotate the Anvil, it will cam the
Hammers out of engagement. Don't do this; merely
rotate the Anvil until it comes up solid.
3. Hold the Hammer Frame firmly and without
disturbing the hammers, gently lift the Anvil while
simultaneously rotating it clockwise about 1/8 of a
turn, from the Hammer Frame.
4. With the Anvil removed, lift out the two Hammer
Pins.
The twin hammers are now free to slide from the
Hammer Frame. Be careful do not to drop them.
Disassembly of the Motor
When pulling, disassembling or assembling the
motor, we recommend replacement of the Motor
Gasket (7).
1. Remove the Motor Assembly from the Housing (19)
by pushing on Power Management Dial (35) from the
back of the Housing. Refer to Dwg. TPD1322.
POWER
MANAGEMENT
DIAL
If the Motor Assembly cannot be removed from the
Housing by pushing, tap the Power Management
Dial lightly until the Motor Assembly is free.
2. Remove the Power Management Dial from the rear of
the Cylinder (1). Remove the Power Management
Dial Seal (5A) if it needs to be replaced.
3. Remove the Front End Plate (2) from the Cylinder by
tapping the splined end of the Rotor (5) with a plastic
hammer. If the Front End Plate does not come loose,
secure a center punch in a vise with the point angled
downward and outward from the vise. Grasp the
Cylinder and Front End Plate in one hand and position
the hole in the end of the Rotor against the punch.
Be careful not to drop the Cylinder since it can be
damaged by hitting a hard surface.
Using the other hand, tap the punch with a hammer
while pressing the Rotor against the punch. After a
few taps, the Front End Plate will slide off of the
Cylinder.
To prevent damage to the Cylinder, do not tap or
strike Cylinder on a hard or metallic surface when
removing the Rotor Bearings (3).
MAINTENANCE SECTION

To remove the Front Rotor Bearing, hold the Front End
Plate with Front Rotor Bearing down and tap the Front

Motor Gasket (7).
When removing the Motor Gasket, do not use a
