MAINTENANCE SECTION
6. Install the Rear End Plate Assembly (11), flat face
leading, on the rear hub of the Rotor. Make certain the
Cylinder Alignment Pin enters the hole in the Rear End
Plate.
7. Using snap ring pliers, install the Rear End Plate
Assembly Retainer (12) in the annular groove on the
rear rotor hub to secure the assembly in position.
8. Set the assembled motor aside.
Assembly of the Gearing
1. Work some IRAX No. 67 Grease into the gearing of
the Spindle Assembly (29).
2. Insert the threaded end of the Spindle Assembly into
the threaded end of the Gear Case (30) while meshing
the teeth of the gears with the spline inside the Gear
Case.
3. Support the gear end of the Spindle Assembly on the
table of an arbor press while leaving clearance for the
Gear Case. Using a piece of tubing that will clear the
shaft and contact the inner ring of the Spindle Bearing
(31), press the Bearing onto the shaft of the Spindle
Assembly until it contacts the gear hub.
4. Using snap ring pliers, install one of the Bearing Stops
(33) in the internal groove nearest the Bearing.
5. Apply some IRAX No. 67 Grease to the Bearing
Spacer (32) and slide it onto the shaft of the Spindle
Assembly with the smaller end trailing.
6. Using snap ring pliers, install the second Bearing Stop
in the internal gear case groove nearest the threaded
spindle end.
7. Stand the assembled Gear Case on the table of an arbor
press with the output Spindle upward. Install the
Spindle Cap Bearing (34) over the output shaft, and
using a piece of tubing that contacts the outer ring of
the Bearing, press the Bearing into the Gear Case
against the Bearing Stop.
8. For Series RG2C, RG2F, RG2G, RG2H and RG2J,
insert the Planet Gear Head Spacer (28) and Planet
Gear Head Assembly (25), spline hub leading, into the
open end of the Gear Case.
9.
For Series RG2F, RG2G, RG2H and RG2J,
apply
IRAX No. 67 Grease to the three Planet Gears (26) and
install them on the shafts of the Planet Gear Head
Assembly.
10. For Series RG2G and RG2F, apply IRAX No. 67
Grease to the Gear Head Pinion (27) and while
meshing the gear teeth, insert it in the opening between
the three Planet Gears.
11. For Series RG2C, install the Drive Plate (24) on the
shafts of the Planet Gear Head Assembly.
For Series RG2A, install the Drive Plate (24) on the
shafts of the Spindle Assembly.
12. For Series RG2C, RG2F, RG2G, RG2H and RG2J,
place the Gear Head Spacer (23) in the Gear Case and
secure the assembly by using snap ring pliers to install
the Gear Retainer (22) in the annular groove inside the
Gear Case.
Assembly of the Tool
1. Grasp the hex of the Inlet Bushing Assembly (4) in
vise jaws with the Throttle Valve (8A) upward. Pull
the stem of the Valve fully outward to enable proper
engagement with the trigger stem.
2. Hold the Motor Housing (1) above the Bushing and
align the two cut out slots in the inlet end of the Motor
Housing with the tabs on the Inlet Bushing Retainer
(7).
3. Lower the Housing onto the Bushing until the bottom
of the Housing contacts the retainer tabs. If necessary,
squeeze the Retainer to start the tabs into the Housing.
Push down on the Housing until the tabs engage the
two slots in the Housing. Visually inspect the Housing
to make certain that both tabs entered the slots in the
Housing.
4. Remove the Housing from the vise jaws.
5. Grasp the spline of the Rotor (15) and align the
assembled motor so that the End Plate Alignment
Dowel (18) is positioned at twelve o’clock in the
Housing. It must be aligned with the notch through the
threads in the Motor Housing. Insert the assembled
motor in the Housing. When the motor is seated
properly, the groove below the housing threads for the
Motor Seal (20) will be clearly visible.
6. Moisten the Motor Seal with o--ring lubricant and
carefully work it into the Housing against the Front
End Plate (17). Use a hex wrench, ball point pen or
other non--damaging tool to make certain it is
completely seated under the housing threads against
the End Plate.
7. Align the tab on the Motor Clamp Washer (21) with the
notch in the Housing and the hole in the Washer with
the Alignment Dowel in the End Plate and insert the
Washer into the Housing . Make certain the Dowel
enters the hole in the Washer and the Washer is flat
against the Motor Seal. Failure to have the Washer
flat, will cause the motor to lock up.
8. While engaging the spline of the rotor shaft with the
gearing in the assembled Gear Case (30), thread the
two assemblies together hand tight.
