5. Press out the (28) Pin from the (31) Housing and remove the
(27) Lever then press out the (30) Sleeve.
ASSEMBLY INSTRUCTIONS
Note: All assembly must be done with clean dry parts and all
bearings are to be pressed in place by the correct tools and
procedures as outlined by the bearing manufacturers.
Housing Assembly:
1. Install the (27) Throttle Lever into (31) Housing with the (28)
Pin.
2. Lightly grease (33) O-Ring and place it on the (34) Speed
Control. Install the (32) Valve Stem, (33) O-Ring (cleaned and
lightly greased) and insert the Speed Control into (31) Hous-
ing in the midway position. Install (35) Retaining Ring.
Caution: Make sure the (35) Retaining Ring is completely
snapped into groove in the (31) Housing.
3. Install the (53) Seat, the (54) Valve and (55) Spring. Coat the
threads of the (56) Bushing Assembly with 1 or 2 drops of
Loctite® 222 or equivalent non-permanent pipe thread seal-
ant. Screw the assembly into the (31) Housing. See "Parts
Page" for torque settings. Place a clean (50) Muffler and (51)
Plate into the exhaust port of the Housing. Be careful not
to lose the Plate and Muffler out of the exhaust before it is
secured in one of the following steps.
4. Note: If the machine is a vacuum model proceed with the
appropriate vacuum exhaust assembly instructions, otherwise
please continue. Place a clean (50) Muffler in the (52) Muffler
Housing and screw the (52) Muffler Housing into the exhaust
port of the (31) Housing. See the "Parts Page" for torque
settings.
For CV exhaust machines:
A. Take the (67) Ø ¾ in./19 mm SuperVAC™ CV Swivel Exhaust
Assembly or the (66) Ø 1 in./28 mm SuperVAC™ CV Swivel
Exhaust Assembly and put the "tongue" on the male end of
it into the female end of the (42) CV/SGV Shroud. With the
swivel end of the SuperVac™ Exhaust angled towards the
ground, work the "tongue" and male end into the female end
of the CV/SGV Shroud by rotating the swivel end up and in at
the same time until it seats.
B. Thread the (70) Screw and (69) Washer into the mounting
hole of the (67) Ø ¾ in./19 mm SuperVAC™ CV Swivel
Exhaust Assembly or the (66) Ø 1 in./28 mm SuperVAC™ CV
Swivel Exhaust Assembly and (31) Housing until the end of it
is flush with the inside surface of the Housing. Place the (68)
Nut into the cavity of the Housing and thread the Screw into
them. See "Parts Page" for torque settings.
C. Place a clean (50) Muffler in the (52) Muffler Housing and
screw the Muffler Housing into the exhaust port of the (31)
Housing. See the "Parts Page" for torque settings.

For SGV exhaust machines:
D. Lightly grease two (57) O-Rings and place them over the two
grooves in the (58) SGV Retainer. Slide the SGV Retainer
Assembly into the bore of the (59) Ø 1 in./28 mm SGV Swivel
Exhaust Assembly or the (60) Ø ¾ in./19 mm Hose SGV
Swivel Exhaust Assembly.
E. Verify that the (51) Plate and (50) Muffler are still in the
exhaust port. Attach the SGV Swivel Exhaust Assembly to the
exhaust port of the (31) Housing by means of the SGV Re-
tainer and by taking the male end of the SGV Swivel Exhaust
Assembly and placing it into the female end of the (42) CV/
SGV Shroud. Screw the (58) SGV Retainer into the threaded
exhaust port on the Housing with an (MPA0849) 8 mm Hex
Key Wrench. See the "Part Page" for torque settings. Move
onto the section "Spindle, AirSHIELD™ and Balancer Shaft
Assembly".
Spindle, AirSHIELD™ and Balancer Shaft Assembly:
1. Place the (MPA0203) T-3A 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 washer facing out so that the outside diameter of the
washer will contact the outer diameter of the (20) Bearing.
Lay the (21) Shim on the shoulder of the Spindle. 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 (MPA0204) T-3B 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 (MPA0204)
T-3B 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.
