Disassembly
General Instructions
1. Do not disassemble the motor any further than necessary to
replace or repair damaged parts.
2. Do not remove any part which is a press fit in or on a
subassembly unless the removal of that part is necessary for
repairs or replacement.
3. Whenever grasping a motor or part in a vise, always use leather-
covered or copper-covered vise jaws to protect the surface of the
part or motor and help prevent distortion. This is particularly true
of threaded members and housings.
4. When removing the Planet Gear Shafts (26 or 38), support the
motor end of the assembly and press the Shafts out toward the
motor end. The shaft holes through the web are slightly tapered
so that the Shafts have a tighter fit in the front web.
5. Do not press any needle bearing from a part unless you have a
new needle bearing on hand for installation. Needle bearings are
always damaged during the removal process.
Disassembly of the Motor
1. Unscrew and remove one Air Strainer (1) for nonreversible
models and two Air Strainers for reversible models from the
Backhead (2).
2. Using a 3/16” hex wrench, unscrew and remove the four
Backhead Cap Screws (3), Lock Washers (4) and separate the
Backhead from the Motor Housing (15). Remove the Backhead
Gasket (6).
3. For Standard Exhaust models, slide the Exhaust Deflector (11)
with the Muffler (10) off the Motor Housing. For Piped-Away
Exhaust Models, slide the Exhaust Deflector (11) off the Motor
Housing and remove the Exhaust Deflector Front Seal (11A) and
Exhaust Deflector Rear Seal (11B) from the grooves inside the
Exhaust Deflector.
4. Using a 3/16” hex wrench unscrew and remove the three Gear
Case Cap Screws (32) and Lock Washers (4).
5. Separate the assembled Gear Case (29) from the Motor Housing
and set the assembled Gear Case aside.
6. Remove the Motor Retainer (20) and Motor Retaining Ring (19)
from the Motor Housing.
7. Grasp the pinion of the Rotor (13) and pull the assembled motor
out of the Motor Housing. It may be necessary to gently tap
the face of the Motor Housing with a plastic hammer to jar the
assemble free.
8. Grasp the Cylinder (18) in one hand and using a plastic hammer,
sharply rap the spline at the end of the spline on the end of the
Rotor to remove the Front End Plate (17) and Front Rotor
Bearing (18) which will free the Cylinder and Vanes (12). Remove
the Cylinder Dowel (14).
9. Jar the Front Rotor Bearing out of the Front End Plate by bumping
the End Plate on a wooden block.
10. Using snap ring pliers, remove the Rear Rotor Bearing Retainer (7)
from the hub of the Rotor and remove the Rear Rotor Bearing (8)
and Rear End Plate (9).
Disassembly of the Gearing
1. For all Models except 3800K, 3800M or 3840K, 3840M, grasp
the Gear Head Bearing (23) and pull the assembled
Gear Head (21) out of the Gear Case (29).
2. For all Models except 3800K, 3800M or 3840K, 3840M, using a
bearing puller, pull the Gear Head Bearing off the rear hub of the
Gear Head.
3. For all Models except 3800K, 3800M or 3840K, 3840M,
support the short hub end of the Gear Head on the table of an
arbor press and press the Gear Head Planet Gear Shafts (26) from
the Gear Head. Make certain the Shafts are pressed out toward
the short hub because the holes in the Gear Head are tapered
smaller toward the Gear Head.
4. For all Models except 3800K, 3800M or 3840K, 3840M, remove
the Gear Head Planet Gears (24) from the Gear Head.
5. For Model 3800P or 3840P, remove the Rotor Pinion (22).
6. For all Models except 3800K, 3800M or 3840K, 3840M, If the
Gear Head Planet Gear Bearings (25) must be replaced, press
them from the Planet Gears.
7. For all Models except 3800K, 3800M or 3840K, 3840M, use a
thin blade screwdriver to spiral the Spindle Bearing Retainer (28)
out of the Gear Case.
8. Holding the Gear Case, push the output end of the Spindle (33) to
move the Spindle Assembly out the motor end of the Gear Case.
9. Using a bearing puller, pull the Spindle Rear Bearing (34) off the
rear hub of the Spindle.
10. Using a bearing puller, pull the Spindle Front Bearing (39) off the
front hub of the Spindle.
11. Support the short hub end of the Spindle on the table of an arbor
press and press the Spindle Planet Gear Shafts (38) from the
Spindle. Make certain the Shafts are pressed out toward the
short hub because the holes in the gear frame of the Spindle
are tapered smaller toward the output end of the spindle
shaft.
12. Remove the Spindle Planet Gears (35) from the Spindle.
13. For Models 3800K, 3800M or 3840K, 3840M, if the Spindle
Planet Gear Bearings (36) must be replaced, press them from the
Planet Gears.
For all Models except 3800K, 3800M or 3840K, 3840M, if the
Spindle Planet Gear Bushings (37) must be replaced, press them
from the Planet Gears.

General Instructions
1. Always press on the Inner ring of a ball-type bearing when
installing the bearing on a shaft.
2. Always press on the Outer ring of a ball-type bearing when
pressing the bearing into a bearing recess.
3. Whenever grasping a tool or part in a vise, always use leather-
covered or copper-covered vise jaws. Take extra care not to
damage threads or distort housings.
4. Except for bearings, clean every part and wipe every part with a

so that the Shafts have a tighter fit in the front web.
8. Unless otherwise noted, always press on the stamped end of a
needle bearing when installing a needle bearing into a recess.
Use a bearing inserting tool similar to the one shown in
Dwg. TPD786.
