ASSEMBLY INSTRUCTIONS
NOTE: All assembling 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. Press the (46) Sleeve flush to the top of the (44) Mo-
tor Housing (if disassembled).
2. Lightly grease the o-ring and place it in the groove of
the (47) Valve Stem. Install the Valve Stem into the
(46) Sleeve.
3. Install the (49) Valve Seat, the (50) Valve and the (51)
Spring. Press the (52) Seal Assembly into the (44)
Motor Housing.
4. Install the (48) Throttle Lever into the (44) Motor
Housing with the (45) Spring Pin.
5. Install the (59) Shroud onto the (44) Motor Housing.
6. Install the (53) Gasket and the (54) NV/CV Exhaust
Nozzle using the three (55) Screws. Torque settings
to be 2.4 - 3.4 N-m (21 - 30 in-lbs). Insert the (56)
Exhaust Tubing and the (58) Inlet Tubing into the (57)
Tubing Clamp. Then insert the Exhaust Tubing into
the NV/CV Exhaust Nozzle and insert the Inlet Tubing
into the (52) Seal Assembly.
7. Install the two (38) Mufflers, (36) O-Ring, (35) Captive
Ring, (37) O-Ring into the (39) End Cap. Lightly
grease the o-rings before installation.
8. Coat the threads of the (40) Inlet Bushing Assem-
bly with 1 or 2 drops of Loctite™ 222 or equivalent
non-permanent pipe thread sealant. Screw the Inlet
Bushing Assembly into the inlet port on the (39) End
Cap until hand tight. Torque settings to be 6.8 - 8.1
N-m (60 - 72 in-lbs).
9. Insert the (58) Inlet Tubing into the (35) Captive Ring.
Make sure that the Inlet Tubing is slide all the way
to the bottom of the hole. Air will leak out if the Inlet
Tubing is not slide all the way to bottom of the hole.
10. Install the (32) Muffler and (33 and 34) Seals into the
(31) Housing.
11. Install the internal housing components into the (31)
Housing. Then install the (62) Housing.
12. Install the Torx® (41 and 63) Screws. Torque setting
to be 3.0 - 3.4 N-m (27 - 30 in-lbs) for the 15 mm

Planetary Spindle Assembly and Bearing Press Tool
Instructions:
1. Place the T-10A Spindle Bearing Pressing Tool Base
(Included in MPA0928 Kit) onto a flat, clean surface
of a small hand press or equivalent with the spindle
pocket facing upward. Place the (23 or 24) Spindle
Assembly into the spindle pocket by using its three
planetary gear shafts to align it with the three bores in
the Pressing Tool Base.
2. Place the (25) Bearing (no seals/shields) onto the
Spindle shaft. 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 the Spindle
using the T-10B Spindle Bearing Press Tool Top
(Included in MPA0928 Kit) as shown in Figure .
3. Place the (26) Shim over the Spindle shaft and onto
the face of the (25) Bearing, making sure it is on cen-
ter. Press the (two seals) (27) Bearing down using
the T-10B Spindle Bearing Press Tool Top (Included in
MPA0928 Kit), being careful to make sure the Shim is
still centered on the vertical axis of the Spindle shaft
and Bearing. Secure the (28) Retaining Ring onto the
end of the Planetary Spindle Assembly.
4. If the (20) Ring Gear was removed, press it into the
(22) Spindle Housing until it rests on the shoulder.
5. Lightly press the entire Planetary Spindle Assembly
into the bore of the (22) Spindle Housing. Secure
the (29) Retaining Ring into the groove of the Spindle
Housing.
6. Place the three (19) Needle Bearings onto the plan-
etary shafts of the Planetary Spindle Assembly. Place
the three (18) Planet Gears onto the Needle Bearings.
Set the finished assembly aside being careful to not
let the Planetary Gears or Needle Bearings fall-out.
