2. Lightly grease (36) O-Ring and place it on the (37) Speed
Control. Install (35) Valve Stem, (36) O-Ring (cleaned and
lightly greased) and insert the Speed Control into (33) Hous-
ing in the midway position. Install (38) Retaining Ring.
Caution: Make sure the (38) Retaining Ring is completely
snapped into groove in the (33) Housing.
3. Install the (49) Seat, the (50) Valve and (51) Spring. Coat the
threads of the (52) Bushing Assembly with 1 or 2 drops of
Loctite® 222 or equivalent non-permanent pipe thread seal-
ant. Screw the assembly into the (33) Housing. See "Parts
Page" for torque settings.
Note: If the machine is a vacuum model, proceed with the appro-
priate vacuum exhaust assembly instructions, otherwise please
continue.
4. Place a clean (48) Muffler and the (47) Plate into the exhaust
port of the (33) Housing.
5. Place a clean (46) Muffler in the (48) Muffler Housing and
screw the Muffler Housing into the exhaust port of the (33)
Housing. See "Parts Page" for torque settings.
6. Install the (53) Snap-In Vacuum Cover Plate.
For CV exhaust machines:
A. Attach the (54) Snap-In Exhaust Adapter.
B. Take the (65) Ø 1 in./28 mm SuperVAC™ CV Swivel Exhaust
Assembly or the (64) Ø ¾ in./19 mm SuperVAC™ CV Swivel
Exhaust Assembly and put the "tongue" on the male end of it
into the female end of the (54) Snap-In Exhaust Adapter. With
the swivel end of the SuperVAC™ Exhaust angled towards
the ground work the "tongue" and male end into the female
end of the Snap-In Exhaust Adapter by rotating the swivel
end up and in at the same time until it seats.
C. Place the (66) Nut into the cavity of the Housing. Place the
(67) Washer onto (68) Screw and insert into the mount-
ing hole of the (65) Ø 1 in./28 mm SuperVAC™ CV Swivel
Exhaust Assembly or the (64) Ø ¾ in./19 mm SuperVAC™
CV Swivel Exhaust Assembly and (33) Housing. See "Parts
Page" for torque settings.
D. Place a clean (46) Muffler and the (47) Plate into the exhaust
port of the (33) Housing.
E. Place a clean (46) Muffler in the (48) Muffler Housing and
screw the Muffler Housing into the exhaust port of the (33)
Housing. See "Parts Page" for torque settings
For SGV exhaust machines:
A. Attach the (54) Snap-In Exhaust Adapter.
B. Lightly grease two (56) O-Rings and place them over the two
grooves in the (55) SGV Retainer Assembly. Slide the SGV
Retainer Assembly into the bore of the (57) Ø 1 in./28 mm
SGV Swivel Exhaust Assembly or the (58) Ø ¾ in./19 mm
Hose SGV Swivel Exhaust Assembly.

C. Attach the (55) SGV Swivel Exhaust Assembly to the exhaust
port of the (33) Housing by means of the SGV Retainer
Assembly and by taking the male end of the SGV Swivel
Exhaust Assembly and placing it into the female end of the
(54) Snap-In Exhaust Adapter. Screw the SGV Retainer
Assembly into the threaded exhaust port on the Housing with
an (MPA0849) 8 mm Hex Key Wrench. See "Parts Page" for
torque settings. Move onto the section "Spindle, AirSHIELD™
and Balancer Shaft Assembly".
Spindle, AirSHIELD™ and Balancer Shaft Assembly:
1. Place the (MPA0201) T-2A Spindle Bearing Pressing Tool
Base onto a flat, clean surface of a small hand press or
equivalent with the spindle pocket facing upward. Place the
(24) Spindle into the spindle pocket with the shaft facing
upward. See Figure 3.
2. Place the (22) Washer on the (24) Spindle shaft with the
curve of the Washer facing up so that the outside diameter of
the Washer will contact the outer diameter of the (20) Bear-
ing. Place the (72) Dust Shield onto the Spindle shaft. Place
the (21) Shim onto the shoulder of the Spindle. Note: Be
sure that the Dust Shield is past the shoulder where Spacer
rests. Place the Bearing (one seal) on the Spindle with the
seal side toward the Washer. Note: Make sure that both the
inner and outer races of the Bearings are supported by the
Bearing Press Tool when pressing them into place. Press the
Bearing onto the shoulder of Spindle using the (MPA0202)
T-2B Spindle Bearing Pressing Tool Top as shown in Figure
3.
3. Place the (19) Shim over the (24) Spindle shaft and onto the
face of the (20) Bearing making sure it is on center. Press the
(18) (no seals/shields) Bearing down using the (MPA0202)
T-2B Spindle Bearing Pressing Tool Top, being careful to
make sure the Shim is still centered on the vertical axis of the
Spindle shaft and Bearing. See Figure 4. When the Spindle
Assembly is done correctly, the Bearings will rotate freely but
not loosely and the Shim can be moved but will not slide or
move by gravity.
4. Snap the (17) Retaining Ring onto the (24) Spindle Assembly
making sure it is completely snapped into the groove.
5. Take the (14) Filter and center it on the small bore of the (13)
Shaft Balancer that the original Filter was in before removal.
With a small diameter screwdriver or flat-ended rod, press
the Filter into the bore until it is flat in the bottom of the bore.
Place the (15) Valve into the bore so it is oriented correctly,
then press the (16) Retainer into the bore until it is lightly
seated against the Valve.
6. Apply a pin head size drop of Loctite® #271 or equivalent to
the outside diameter of each of the bearings on the spindle
assembly. Spread the drop of bearing locker around the
Bearing (18)
Shim (19)
