Disassembly
General Instructions
Do not disassemble the tool any further than necessary to replace
or repair damaged parts.
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.
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.
Do not disassemble the tool unless you have a complete set of
new gaskets and O-rings for replacement.
Disassembly of the Tool
1. Keep the Air Strainer Screen (67) clean. Periodically, as experience
indicates, unscrew the Air Strainer Body (69) from the Air Strainer
Cap (66) and wash the Air Strainer Screen in a clean, suitable,
cleaning solution. Push the prongs on the Screen Support (68)
into one of the Screen and insert the screen end rst, into the
body when assembling the strainer.
NOTICE
The external thread on the Outer Feed Screw (43) or Motor
Mounting Stud (217) is left-hand.
2. Rotate the Feed Screw Cap (72) or Motor Mounting Stud
Cap (218) clockwise to remove.
3. Do not pry the Backhead (115, 210) from the Motor Housing (1,
200, 202). Grasp the Oil Chamber Plug (19, 211) in a copper-
covered or leather-covered vise jaws and pull on the Housing if
the Backhead cannot be lifted o with the ngers.

NOTICE
The Governor Assembly (27) has left-hand threads.
4. Rotate the Governor Assembly clockwise to remove it.
5. Never clamp the Cylinder (41) in a vise. When disassembling the
Motor:
Grasp the Cylinder in one hand.
Insert a small rod into the rotor bore and drive the hub on the
Rotor out of the Rear Rotor Bearing (36).
Support the Front End Plate (39) and press the rotor front hub
out of the Front Rotor Bearing (37).
6. Remove the Throttle Body Set Screw (52) or Forward Inlet Stud
Set Screw (204) from the side of the Motor Housing before
attempting to pull the Throttle Body (55) or Forward Inlet
Stud (203) from the Motor Housing.
For Drills and Motors with Planetary Gearing.
Unscrew the three Planet Gear Frame Set Screws (86) from the Planet
Gear Frame (85) before attempting to press the Spindle out of the
Planet Gear Frame.

Assembly
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. Unless otherwise noted, always press on the stamped end of a
needle bearing when installing the needle bearing in a recess.
4. Whenever grasping a tool or part in a vise, always use leather-
covered or copper-covered vise jaws. Take extra care with
threaded parts and housings.
5. Always clean every part and wipe every part with a thin lm of oil
before installation.
6. Apply a lm of O-ring lubricant to all O-rings before nal
assembly.
7. Check every bearing for roughness. If an open bearing must be
cleaned, wash it thoroughly in a clean, suitable, cleaning solution
and dry with a clean cloth. Sealed or shielded bearing should
never be cleaned. Work grease thoroughly into every open
bearing before installation.
Assembly of the Tool
1. Press the Rear Rotor Bearing (36), shielded side rst, into the
recess in the Rear End Plate (38) with an arbor that will contact
only the bearing outer race. Press on the bearing inner race when
installing the assembly on the hub of the Rotor (33).
2. Press the Front Rotor Bearing (37), shielded side rst, onto the
front hub of the Rotor with a sleeve that will clear the pinion and
contact only the bearing inner race.
3. After installing one End Plate and Rotor Bearing on the rotor hub,
insert a Vane (40) into each slot in the Rotor. Place the Cylinder
(41) over the Rotor and against the installed End Plate being sure
the Cylinder is positioned with its attened rim toward the pinion
end of the Rotor so that the ats will coincide with those on the
Front End Plate when the motor is assembled.
NOTICE
The Governor Assembly (27) has left-hand threads.
4. When installing a new Governor Assembly, screw the Adjusting
Nut onto the governor stem until the proper dimension “A” as
shown in Dwg.TPD497. This will usually result in the proper
governed free speed. However, this is only an approximate
setting and further adjustment may be necessary. Screw the
nut farther onto the stem to increase the speed; back it o to
decrease the speed.
Governor Adjustment
A=1-29/32” (48 mm) For Drills and Motors with Standard Throttle
A=1-1/32” (52 mm) For Motors with Remote Control
A
(Dwg. TPD497)
The correct governed free speeds for these Models are:
Model Speed
rpm
33H, 33H-EU, 33H51 and 33H51-EU 800
33J, 33J-EU, 33SJ, 33SJ-EU, 33J51 and 33J51-EU 450
33SKA, 33SKA-EU, 33SK51 and 33SK51-EU 300
33SM, 33SM-EU, 33SM51 and 33SM51-EU 185
5. Be sure both rubber Air Port Gaskets (8) are in good condition
and are positioned, lip side rst, in the air ports in the Motor
Housing (1, 200, 202) before installing the Multi-Vane motor in
the Motor Housing.
6. Draw the Backhead (15) evenly against the Backhead Gasket (14)
on the face of the Motor Housing by turning each Backhead Cap
Screw (22, 23) a little at a time until all are tight.
NOTICE
The two sets of Housing Studs, Nut and Lock Washer have been
replaced by two Backhead Short Cap Screws (22) using Copper
Washers (24A).
7. If the Housing Studs need replacing in an old Motor Housing,
order two Backhead Short Cap Screws R3H-57 and two Copper
Washers DLC-504B.
8. Note the stamping “THRUST HERE” on one side of the Spindle
Thrust Bearing (92). Install the Bearing unstamped side rst on
the spindle hub.
For Drill and Motors with Spur Gearing
Install an Intermediate Gear Bearing (96) at each end of the
Intermediate Gear (95). Mesh the small gear of the compound
Intermediate Gear with the gear on the Spindle (81, 208) and install
the Spindle Assembly and Intermediate Gear simultaneously in either
the Gear Case (102, 212) or the Motor Housing (1, 200 or 202).
For Drills and Motors with Spur Gearing
Assemble the Spindle (81 or 208) and gearing in the Gear Case (102)
and Gear Case Cover (113 or 214). Install this assembly as a unit on
the Motor Housing.
