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 (28) Sleeve into housing. Install (25) Throttle Lever into
(29) Housing with the (26) Pin.
2. Lightly grease (31) O-Ring and place it on the (32) Speed
Control. Install the (30) Valve Stem, O-Ring (cleaned and
lightly greased) and insert the Speed Control into (29) Hous-
ing in the midway position. Install (33) Retaining Ring.
Caution: Make sure the (33) Retaining Ring is completely
snapped into groove in the (29) Housing.
3. Install the (51) Seat, the (52) Valve and (53) Spring. Coat the
threads of the (54) Bushing Assembly with 1 or 2 drops of
Loctite® 222 or equivalent non-permanent pipe thread seal-
ant. Screw the assembly into the (29) Housing. See "Parts
Page" for torque settings. Place a clean (48) Muffler and (49)
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 (48) Muffler in the (50) Muffler
Housing and screw the (50) Muffler Housing into the exhaust
port of the (29) Housing. See the "Parts Page" for torque
settings.
For CV exhaust machines:
A. Take the (63) Ø ¾ in./19 mm SuperVAC™ CV Swivel Exhaust
Assembly or the (62) 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 (40) 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 (66) Screw and (65) Washer into the mounting
hole of the (63) Ø ¾ in./19 mm SuperVAC™ CV Swivel
Exhaust Assembly or the (62) Ø 1 in./28 mm SuperVAC™ CV
Swivel Exhaust Assembly and (29) Housing until the end of it
is flush with the inside surface of the Housing. Place the (64)
Nut into the cavity of the Housing and thread the Screw into
them. See "Parts Page" for torque settings.
C. Place a clean (48) Muffler in the (50) Muffler Housing and
screw the Muffler Housing into the exhaust port of the (29)
Housing. See the "Parts Page" for torque settings.

grooves in the (56) SGV Retainer. 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.
Verify that the (49) Plate and (48) Muffler are still in the
exhaust port. Attach the SGV Swivel Exhaust Assembly to the
exhaust port of the (29) 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 (40) CV/
SGV Shroud. Screw the (56) 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".
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
(22) Spindle into the spindle pocket with the shaft facing
upward. See Figure 3.
Place the (20) Washer on the (22) Spindle shaft with the
curve of washer facing out so that the outside diameter of the
washer will contact the outer diameter of the (18) Bearing.
Place the (72) Dust Shield on the Spindle Shaft. Note: Be
certain that the (72) Dust Shield is past the shoulder when
(19) shim is assembled. Lay the 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.
Snap the (17) Retaining Ring onto the (22) Spindle Assembly
making sure it is completely snapped into the groove.
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.
