8a. For SGV machines: Insert the (47) Inlet Tubing into the End
Cap Assembly. Install the (63) Hose Seal into the (60) End
Cap.
8b. For NV and CV machines: Insert the (47) Inlet Tubing into the
(59 or 60) End Cap.
9. Install the (17) Muffler and (19) Seals into the (16) Housing.
Lightly grease the seals before installation.
10. Install the internal components into the (16) Housing. Then
install the (51) Housing.
11. Install the (48 and 50) Screws using a T-20 Torx® driver.
Torque setting to be 27- 30 in-lbs (3.0-3.4 N-m) for the 15 mm
long Screw. Torque setting to be 29- 33 in-lbs (3.3-3.7 N-m)
for the 30 mm long Screw.
12. Lightly grease the (53) O-Ring and place it in the groove on
the (52) Speed Control. Insert the Speed Control into the
(26) Motor Housing in the full on (horizontal) position. Install
the (54) Retaining Ring. Caution: Make sure the Retaining
Ring is completely snapped into groove in the Motor Housing.
13. Install the (24) Spacer Ring into the (25) Hanger. Secure
the Hanger by screwing in the (15) Plug(s) and/or install the
(48) Side Handle. Disregard this step if these parts were not
purchased with the tool.
Motor Assembly:
1. Place a new (13) Front Bearing Dust Shield onto the (14)
Shaft Balancer. Be sure that the Dust Shield is flat against
the Shaft Balancer.
2. Lightly grease the (11) O-Ring with a light mineral grease and
place it in the groove of the (12) Lock Ring, then place it on
the (14) Shaft Balancer with the O-Ring facing towards the
keyway.
3. Use the larger end of the (MPA0494) T-13 Bearing Press
Sleeve to press the front (10) Bearing (with two Shields) onto
the shaft of the (14) Shaft Balancer.
4. Slide the (9) Front Endplate with the bearing pocket facing
down onto the motor shaft. Gently press the Front Endplate
onto the (10) Bearing using the larger end of the (MPA0494)
T-13 Bearing Press Sleeve until the front Bearing is seated
in the bearing pocket of the Front Endplate. Caution: Only
press just enough to seat the Bearing into the pocket. Over-
pressing can damage the Bearing or Front Endplate.
5. Place the two (8) Keys into the grooves of the (14) Shaft
Balancer. Place the (7) Rotor onto the shaft of the Shaft
Balancer, making sure that it is a light slip fit.
6. Place the (5) Cylinder Assembly over the (7) Rotor with the
shorter end of the spring pin in the Cylinder engaging the
blind hole in the (9) Front Endplate. Note: The spring pin
must project .060 in. (1.5 mm) above the flanged side of the
Cylinder. Oil the five (6) Vanes with a quality pneumatic tool
oil and place in the slots in the Rotor. One or two drops of oil
should be sufficient.
7. Press fit the rear (2) Bearing (two shields) into the (3) Rear
Endplate with the T-1B Bearing Press Tool. Make sure the
T-1B Press Tool is centered on the O.D. of the outer race of
the Bearing. Lightly press fit the Rear Endplate and Bearing
over the (14) Shaft Balancer using the small end of the
(MPA0494) T-13 Bearing Press Sleeve. The Sleeve should
press only the inner race of the Bearing. Important: The Rear
Endplate and Bearing is pressed correctly when the Cylinder
is squeezed just enough between the endplates to stop it
from moving freely under its own weight when the motor
assembly is held horizontal, but be able to slide between the
Endplates with a very light force. If pressed too tightly the
motor will not run freely. If the pressed assembly is too loose,
the motor will not turn freely after assembly in the (26) Motor
DOC 2624
Housing.
8. Secure the assembly by placing the (1) Retaining Ring in the
groove of the (14) Shaft Balancer. Caution: The Retaining
Ring must be placed so that the middle and two ends of the
hoop touch the Bearing first. Both raised center portions
must be securely "snapped" into the groove in the Shaft
Balancer by pushing on the curved portions with a small
screwdriver.
9. Lightly grease the (4) O-Ring and place in the air inlet of the
(5) Cylinder Assembly.
10. Lightly grease or oil the inside diameter of the (26) Motor
Housing, line up the spring pin of the Cylinder Assembly
with the marking on the Motor Housing and slide the Motor
Assembly into the Motor Housing. Make sure the spring pin
engages the pocket in the Motor Housing.
11. Carefully screw the (12) Lock Ring into the (26) Motor Hous-
ing with the (MPA0025) T-6 Motor Lock Ring Wrench/Spindle
Puller Tool. Torque settings to be 55-65 in-lbs (6.2-7.3 N-m).
Note: A simple technique to assure first thread engagement
is to turn the Lock Ring counter-clockwise with the T-6 Motor
Lock Ring Wrench/Spindle Puller while applying light pres-
sure. You will hear and feel a click when the lead thread of
the Lock Ring drops into the lead thread of the housing.
12. Press the (30) Bearing into the bore of the (29) Pad backing.
13. Take the assembly of the (29) Pad backing and (30) Bearing,
with the Bearing facing towards you, place the (31) Spacer
and (32) Spindle Bearing Dust Shield on the Bearing.
14. Install the (33) Belleville Washer by screwing in (44) Screws
using a 2.5mm L wrench. Torque setting to be 21-30 in-lbs
(2.4-3.4 N-m).
15. Install the (34) Balancer by screwing in (35) Screw. Torque
setting to be 95-105 in-lbs (10.7-11.8 N-m).
16. Place the tool on top of the (36) Pad. Be sure that the (29)
Pad backing is fully engaged into the studs on the Pad.
17. Secure the (36) Pad to the tool by screwing in (28) Screws
using a T-20 Torx® driver. The Screws will have to be in-
serted thru the access hole on the outside of the (27) Shroud.
Torque setting to be 21-30 in-lbs (2.4-3.4 N-m).
18. Close up the access hole in the (27) Shroud.
Testing:
Place 3 drops of quality pneumatic air tool oil directly into the
motor inlet and connect the machine to a 90-psig (6.2 bar) air
supply. A 10,000 RPM tool should run between 9,500 to 10,500
RPM when the air pressure is 90-psig (6.2 bar) at the inlet of the
tool while the tool is running at free speed. This free speed will
be about 500 RPM to 1,000 RPM less when a Vacuum or Hook
Face Pad is used because of wind resistance. This will not affect
performance when sanding.
