(28) Spring Pin.
2. Lightly grease the (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 the (33)
Housing in the midway position. Install the (38) Retaining
Ring.
3. Install the (49) Seat, (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 DB 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) DB Retainer Assembly. Slide the DB
Retainer Assembly into the bore of the (57) Ø 1 in./28 mm DB
Swivel Exhaust Assembly or the (58) Ø ¾ in./19 mm Hose
DB Swivel Exhaust Assembly.
C. Attach the (55) DB Swivel Exhaust Assembly to the exhaust
port of the (33) Housing by means of the DB Retainer As
-
sembly and by taking the male end of the DB Swivel Exhaust
Assembly and placing it into the female end of the (54) Snap-
In Exhaust Adapter. Screw the DB 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: Make
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 centred. 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 assembled correctly, the Bearings will rotate
freely but not loosely and the Shim can be moved but will not
slide or move under 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 rod with a flattened end,
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
Press Tool Top
