Disassembly
General Instructions
1. Do not disassemble the tool any further than necessary to replace
or repair damaged parts.
2. Whenever grasping a tool or part in a vise, always use leather–
covered or copper–covered vise jaws to protect the surface of
the part and help prevent distortion. This is particularly true of
threaded members and housings.
3. Do not remove any part which is a press t in or on a
subassembly unless the removal of that part is necessary for
repairs or replacement.
4. Do not disassemble the tool unless you have a complete set of
new gaskets and O–rings for replacement.
Maintenance Procedure
1. Keep the air strainer clean. Periodically, as experience indicates,
unscrew the Air Strainer Body (94) from the Air Strainer Cap (91)
and wash the Air Strainer Screen (92) in a clean, suitable, cleaning
solution. Push the prongs on the Air Strainer Screen Support (93)
into one end of the Screen and insert the Screen, support end
rst, into the Body when assembling the strainer.
2. For ReversibleTools, remove the throttle body set screw from the
side of the Motor Housing (1 or 252) before attempting to pull
the Throttle Body (84) from the Housing.
3. The thread on the Governor Assembly (21) is a left–hand thread;
turn it clockwise to unscrew it from the Rotor (27).
WARNING
Never clamp the Cylinder (32) in a vise.
4. When disassembling the motor, grasp the Cylinder in one hand.
Insert a 5/16” diameter rod into the bore of the Rotor (27) and
drive the rotor hub out of the Rear Rotor Bearing (29). Unscrew
the Rotor Pinion (35) from the Rotor and screw a 3/8”–24 thread
bolt in its place. Support the Front End Plate (33) and press the
rotor front hub out of the Front Rotor Bearing (34).
5. The front hub of the Rotor contains a tapered socket.The rim of
the Front End Plate is atted, one at on Series 2X; two on Series
22. When assembling the motor, slip the Front End Plate, crescent
grooved side rst, over the rotor front hub and retain it by
pressing the Front Rotor Bearing shielded side rst, onto the rotor
hub as far as possible without binding the End Plate against the
rotor face. Clean and dry the tapered surfaces of the Rotor and
Rotor Pinion and screw the Pinion tightly into the Rotor. Insert a
Vane (31) into each vane slot in the Rotor. Place the Cylinder over
the Rotor and onto the End Plate. Align the air ports and dowel
hole in the Cylinder and End Plate. If they cannot be aligned,
invert the Cylinder. Install the Rear End Plate (30), crescent
grooved side rst, and Rear Rotor Bearing (29), shielded side rst.
6. When applying the Backhead (12 or 260), draw it evenly against
the Backhead Gasket (11) on the face of the Motor Housing (1 or
252) by turning each Backhead Cap Screw (36) a little at a time
until all are tight.
For All Models Except 22N
1. Insert a small screwdriver through one of the holes in the Spindle
Gear (62) and pry the Bearing Retainer (61) out of the groove in
the Gear Case (54) before attempting to withdraw the Spindle
Assembly from the Gear Case.
2. Press the Spindle (55) out of the Spindle Gear and remove the
Spindle Gear Key (63) from the Spindle before attempting to
press the Spindle out of the Thrust Bearing (60), Spindle Bearing
Spacer (59) and Spindle Bearing (58).
3. Press the Intermediate Gear Front Bearing (68) into the Gear Case
before installing the Spindle Assembly.
4. In the order named, press the Spindle Bearing, sealed side rst,
Spindle Bearing Spacer and Thrust Bearing, shielded side rst,
onto the Spindle.
5. Lay the Bearing Retainer on the web of the recessed hub side of
the Spindle Gear and press the Spindle into the Spindle Gear.
6. Slide the Spindle Assembly into the Gear Case and install the
Bearing Retainer in the groove in the Gear Case with a small
screwdriver inserted through one of the holes in the Spindle
Gear.
For Model 22N
1. Rotate the Spindle Gear (7l) until one of the holes in the gear
web aligns with the notch in the gear case wall. Insert a small
screwdriver into the notch and pry the Bearing Retainer (73) out
of the groove in the Gear Case before attempting to remove the
Spindle Gear Shaft (70) from the Gear Case.
2. Press the Spindle Gear Shaft out of the Spindle Gear and remove
the Spindle Gear Key (72) from the Shaft before attempting to
press the Shaft out of the Spindle Gear Bearing (69).
3. Support the short hub end of the Spindle (55 or 251) and press
on the front end of the Planet Gear Shafts (64) when removing
the Shafts from the spindle gear head. The Planet Gear Rollers
(66) and Roller Retaining Plates (67) are free to drop out when the
Gears are removed from the Spindle. Use care to prevent loss of
these small parts.
4. When assembling the Spindle, coat the inner wall of the Planet
Gears (65) with the recommended grease and insert a Planet
Gear Shaft through each gear bore. Slide twenty–one Planet Gear
Rollers into the space between the gear wall and Shaft. Slip a
Roller Retaining Plate over each end of the Shaft and against the
Rollers. Carefully withdraw the Shafts and insert the Gears into
the gear frame on the Spindle.
5. Install the Spindle Bearing shielded side rst on the Spindle. On
the shielded side, the face of the bearing inner ring is slightly
lower than that of the outer ring. On the opposite side of the
Bearing the faces are ush.
6. Press the Intermediate Gear Front Bearing into the Gear Case
before installing the assembled Spindle Gear Shaft.
7. Lay the Bearing Retainer on the web of the recessed hub side
of the Spindle Gear and press the Spindle Gear Shaft into the
Spindle Gear. Slide the assembled Spindle Gear Shaft into the
Gear Case. Insert a small screwdriver through the holes in the
Spindle Gear and install the Bearing Retainer in the gear case
groove.
