MAINTENANCE SECTION
Assembling the Motor to the Handle
1. Drop the Motor Clamp Washer (48), concave side
first, into the motor bore of the Motor Housing (34).
2. For DAA and DAAT models, apply some grease to
the Shutoff Spool (73) and Valve Return Spring (74).
Install the Spring on the long stem of the Spool and
insert the short stem of the assembly into the hole in
the splined end of the Rotor (41).
3. Hold the Motor Housing horizontally and slide the
assembled motor into the Housing. Make certain the
rotor hex engages the internal hex of the Clutch Shaft
(66) or Drive Shaft (65).
4. Install the two Rotor Bearing Springs (38) in the re-
cess of the Rear Rotor Bearing Housing (37) and
place both in position against the Bearing. Make sure
that the Cylinder Dowel (44) enters the dowel hole in
the Bearing Housing.
5. Install the Motor Clamp Seal (33) on the small hub of
the Motor Clamp Spacer (32).
6. Position the Spacer in the Housing, small hub lead-
ing, so that the slots of the Spacer engage the flat on
the Bearing Housing. While pushing the Spacer to-
ward the motor, rotate the assembly until the align-
ment notch in the Spacer aligns with the pin in the
Housing and the entire assembly moves forward.
If the assembled motor is a tight fit in the Motor
Housing, it may be necessary to insert a wooden or
metal block into the exposed notches of the Motor
Clamp Spacer to rotate the assembly.
7. For DAA and DAAT models, the distance between
the large end of the Motor Housing and the top sur-
face of the large flange of the Shutoff Valve Assem-
bly is critical for efficient operation. The gap must be
between .258” and .264” (6.55 mm and 6.70 mm)
wide. (See Dwg. TPD1251).
If the Clutch Housing or any clutch components
have been replaced, the Shutoff Valv Assembly
will require adjustment.
To determine if the gap is correct, remove the Motor
Clamp Spacer (32);
insert the Shutoff Valve Assembly (31), shaft first,
into the central opening of the motor assembly and
measure the distance with a depth micrometer.
Refer to Dwg. TPD1251.
(Dwg. TPD1251)
If the gap is incorrect, proceed as follows:
a. Remove the Valve Assembly from the motor.
b. Place a wrench on the square of the valve.
c. Insert a hex wrench into the end of the shaft and
turn it clockwise to shorten the gap or counter
clockwise to increase the gap.
d. Install the Valve Assembly and remeasure the
gap. Repeat the process until the distance is
correct.
8. For DAA and DAAT models, when the gap is cor-
rect, remove the Valve Assembly from the motor.
9. Install a Reverse Valve Seal (29) into the groove on
the rear end of the Reverse Valve (28).
10. For DAA and DAAT models, insert the shaft of the
Shutoff Valve Assembly through the central opening
of the Reverse Valve from the large open end.
11. For DAA and DAAT models, insert the Reverse
Valve, large open end leading, with the Shutoff Valve
Assembly into the Handle. The Seal will hold the
parts in position against the Handle.
For DAAS models, insert the Reverse Valve, large
open end leading, into the Handle. The Seal will hold
the parts in position against the Handle.
12. Install the remaining Reverse Valve Seal in the large
opening of the Motor Clamp Spacer.
13. For DAA and DAAT models, insert the shaft of the
Shutoff Valve Assembly into the central hole through
the motor and position the assembled handle against
the assembled motor.
For DAAS models, position the assembled handle
against the assembled motor.
14. Install the four Handle Mounting Screws (26) and
Lock Washers (27) and tighten the Screws between
12 and 18 in–lb (1.4 and 2.0 Nm) torque.
15. Slide the Adjustable Grip (9) onto the Handle.
16. Spread the open end of the Adjustable Grip Latch
(10) slightly and install it on the Handle to capture
the Grip.
