Throttle Valve Spring Seat - Ingersoll Rand CD Serie Manual De Uso Y Mantenimiento

Assembly of the Throttle and Inlet
1. Insert the Throttle Valve Plunger (8) into the Motor
Housing (5).
2. Position the Throttle Lever (6) on the Motor Housing
and using an arbor press, press the Throttle Lever Pin
(7) into the Housing and Lever. The Lever will retain
the Plunger in the Housing.
3. If the Throttle Valve Case (4) was removed, lubricate
the outside and the throttle stem end of the Case with
O–ring lubricant. Using a wooden dowel, push the
Case, open end trailing, into the Motor Housing.
4. If the Throttle Valve Seat (4D) was removed, use a
5/8" wooden dowel with a flat end to push the Seat
into the Motor Housing.
5. Push the small end of the Throttle Valve Spring (4B)
onto the end of the Throttle Valve (4C) with the short
stem until the Spring snaps into position around the
hub and remains there. Install the dish end of the
Throttle Valve Spring Seat (4A) onto the large end of
the Throttle Valve Spring.
6. Holding the Housing with the Lever downward, make
sure the Plunger is out of the way and insert the
assembled Throttle Valve, long stem end leading, into
the housing recess.
7. Push the Inlet Screen (2), closed end leading, into the
bushing of the Inlet Assembly (1). After moistening
the Inlet Seal (3) with o–ring lubricant and being
careful not to nick the Seal on the threads of the Inlet,
install the Seal on the Inlet.
8. Thread the Inlet Assembly into the Housing and
tighten it between 20 to 25 ft–lb (27.1 to 33.9 Nm)
torque.
Assembly of the Motor
Steps common to ALL models
When installing a Rear Rotor Bearing, press the
Rotor Bearing onto the shaft with the shielded side
of the Bearing leading (shield toward the Rotor).
1. If the Rear Rotor Bearing (9) was removed, stand the
Rotor (12) upright on the table of an arbor press with
the threaded end downward. Make sure the threaded
end passes through a hole drilled in a block so that the
Rotor rests against the large rotor body. Press the
Rear Rotor Bearing onto the hub of the Rotor.
2. Install the Rear Rotor Bearing Retainer (11) in the
groove on the hub of the Rotor.
3. Install the Front End Plate (14), counterbored end
trailing, onto the threaded hub of the Rotor. Press the
Front Seal Cup (16), dish end trailing, onto the end of

the Front End Plate Spacer (15) that has the central
hole beveled. Continue pressing until the dish end is
flush with the end of the Spacer. Place the assembled
Spacer, Seal Cup trailing, onto the threaded hub of the
Rotor. Make sure the Seal Cup enters the recess in
the Front End Plate.
Be aware that in the next step, the Front Rotor
Bearing is a double flush ground bearing and must
be installed in a specific manner. The end of the
Bearing with a black stain or hash marks must be
away from the Spacer.
Stand the Rotor on the table of an arbor press with the
threaded end upward and press the Front Rotor
Bearing (17) onto the hub of the Rotor.
Grasp the assembled Rotor in copper–covered or
leather–covered vise jaws with the threaded rotor hub
upward.
Inject approximately 3/4 cc of Ingersoll–Rand No. 68
Grease into the small recess at the bottom of the
motor housing bore. Drop the two Rear Rotor
Bearing Spacers (10) into the bottom of the motor
housing bore.
Assemble the Flow Ring (18) with the Flange (19)
before installing the Flange on the Housing. Mate the
Flow Ring to the end of the Flange without
perforations. The positioning of the Flow Ring is
dictated by the desired exhaust. To set the tool
exhaust, proceed as follows:
a. For front exhaust tools, align the notched
projection on the edge of the Flow Ring with the
letter "F" on the Housing.
b. For rear exhaust tools, align the notched
projection on the edge of the Flow Ring with the
letter "R" on the Housing.
Install the assembled Flange, Flow Ring leading, onto
the front of the Motor Housing.
Position the Flange Clamp (20) against the Flange.
Thread the Arbor Bearing Nut (30) onto the Rotor
(12) and using a torque wrench, tighten the Nut
between 14 and 19 ft–lb (19 and 26 Nm) torque.
Wipe each Vane (13) with a light film of oil and insert
a Vane into each vane slot in the Rotor.
Grasp the Arbor Bearing Nut and insert the assembled
Rotor into the Motor Housing (5).
Grasp the Motor Housing in copper–covered or
leather–covered vise jaws with the Arbor Bearing Nut
upward. Do not distort the Housing.
