Position the Front Rotor Bearing (47) onto the rotor
hub so that the red stained end will be visible when
the Bearing is in the end Plate. Pressing on the inner
race of the Bearing, press the Bearing onto the hub
and into the Front End Plate.
The Clutch Assembly or Drive Shaft Assembly
must be assembled with the motor before attach-
ing them to the Handle. If the Clutch or Drive
Shaft is not assembled, set the motor aside and
assemble the clutch as instructed in the section,
ASSEMBLY OF THE DAA and DAAT CLUTCH
or ASSEMBLY OF THE DAAS DRIVE SHAFT
MECHANISM.
Assembly of the DAA and DAAT Clutch
1. Install two Shutoff Balls (76) into each of the three
holes located radially in the Cam Shaft (78) and then
slide the assembly into the Cam Block (79). Fill the
cam shaft holes with grease to retain the Balls.
2. Press the Clutch Bearing (82) onto the spindle end of
the Clutch Shaft.
3. Install the Reset Spring (75), tapered end leading,
onto the small hub of the Cam Shaft and insert the
assembled parts, Spring first, into the central opening
at the non–threaded end of the Clutch Shaft (66).
4. Apply pressure to the assembly to keep it in the Shaft
and install the three Cam Pins (77) into the radial
holes in the Clutch Shaft and into the slots of the Cam
Shaft to capture the assembly.
5. Position the Clutch Spindle (80) in the bearing end of
the Clutch Shaft and secure it by using a thin blade
screwdriver to spiral the Spindle Retainer (81) into
the groove inside the Clutch Shaft.
6. Fill the holes in the Clutch Shaft near the large flange
with grease and install the three clutch Balls (72) in
the holes. Slide the Cam Follower (71), large end
first, onto the threaded end of the Clutch Shaft and
pull it forward to capture the Balls between the flange
and the Follower.
7. Slide the Clutch Spring (70) and the Clutch Adjusting
Nut Lock (69), notched face trailing, onto the
threaded end of the Clutch Shaft.
8. Secure the components by threading the Clutch Ad-
justing Nut (68), notched face leading, onto the
Clutch Shaft. Insert a #1 Phillips head screwdriver
into the notch of the Nut Lock and one of the notches
in the Nut. Insert the screwdriver far enough to
create a gap between the Nut Lock and Adjusting
Nut. Turn the screwdriver clockwise as you would to
tighten a screw to move the Nut along the Shaft until
it clears the groove for the Clutch Adjusting Nut Stop
(67).
9. Insert the jaws of snap ring pliers into the holes of the
Clutch Adjusting Nut Stop and expand the Stop only
enough to release any pressure against the Clutch
Shaft. While keeping the pressure relieved, screw the
assembled clutch onto the Stop, as you would screw a
nut onto a bolt, until the Stop enters the groove. Ex-
panding the Stop sufficiently to clear the Shaft in a
normal manner will distort the snap ring beyond ac-
ceptable limits.
10. Install the Rear Motor Housing Seal (36), Front Mo-
tor Housing Seal (49) and Hole Cover O–ring (53) in
the grooves in the Motor Housing (34).
11. Slide the Housing Sleeve Assembly (50), large end
first, onto the Motor Housing. Slide the the Clutch
Adjusting Hole Cover (52) onto the Motor Housing
against the Sleeve Assembly.
12. Insert the assembled clutch, Spindle first, into the
Clutch Housing (84).
13. Thread the assembled clutch and Housing onto the
Motor Housing and tighten the joint between 20 and
25 ft–lb (27 and 35 Nm) torque.
When assembling the Gear Case with the Clutch
Housing, make certain the spline of the Clutch
Spindle properly engages the Drive Coupling,
Rotor Pinion or Planet Gears. Improper
engagement will damage the splines and may force
the Clutch rearward causing the Shutoff Valve
Assembly to move out of correct adjustment.
Assembly of the DAAS Drive Shaft Mechanism
1. Press the Drive Shaft Bearing (83) onto the spindle
end of the Drive Shaft (65).
2. Insert the assembled Drive Shaft, spindle end first,
into the Clutch Housing (84).
3. Thread the assembled Drive Shaft and Housing onto
the Motor Housing (34) and tighten the joint between
20 and 25 ft–lb (27 and 35 Nm) torque.
When assembling the Gear Case with the Clutch
Housing, make certain the spline of the Drive
Shaft Assembly properly engages the Drive
Coupling, Rotor Pinion or Planet Gears.
Improper engagement will damage the splines.
