DISASSEMBLY INSTRUCTIONS
Motor Disassembly:
To prevent damage to the motor assembly the following
sequence must be followed:
1. Remove the (35) Pad with the (34) Pad Wrench.
2. Unscrew the (12) Lock Ring with the (MPA0025) T-6
Motor Lock Ring Wrench/Spindle Puller Tool. The
motor assembly and Lock Ring can now be lifted out
of the (32) Motor Housing.
3. Remove the (1) Retaining Ring and the (7) O-Ring
from the (8) Cylinder.
4. Remove the (3) Rear Endplate. This requires sup-
porting the Rear Endplate using a (MPA0416) Bear-
ing Separator and lightly pressing the shaft through
the (2) Bearing and the Rear Endplate. Remove the
(8) Cylinder and the five (5) Vanes and (4) Rotor from
the shaft of the (13) Shaft Balancer. Remove the two
(6) Keys, and then press off the (9) Front Endplate
(with Bearing). Remove the (11) O-Ring and the (12)
Lock Ring. It may be necessary to remove the (10)
Bearing with a Bearing Separator if it came out of the
Front Endplate and stuck to the shaft of the Shaft Bal-
ancer.
5. Remove and discard the (62) Dust Shield from the
(13) Shaft Balancer.
6. Remove the Bearing(s) from the Endplates by using
the (MPA0036) T-8 Bearing Removal Tool to press

(22) Retaining Ring and prise it out.
2. Screw the threaded end of the (MPA0025) T-6 Mo-
tor Lock Ring Wrench/Spindle Puller Tool into the
(21) Spindle until hand tight. Apply gentle heat from
a propane torch or hot air gun to the large end of the
(13) Shaft Balancer until it is about 100 °C (212 °F)
to soften the adhesive. Do not over heat. Remove the
spindle assembly by using the slider to pull the spin-
dle assembly outward. Allow the parts to cool until
they are safe to handle. Do not knock out the spindle
assembly using the T-6 Motor Lock Ring Wrench/
Spindle Puller Tool because this could damage the
(18) Bearing.
3. The AirSHIELD™ components are held in place by a
light press fit against the (16) Retainer. These compo-
nents can be damaged during removal and may need
to be replaced if removed. To remove the Retainer,
use an O-Ring pick or a #8 sheet metal screw to grip
and pull out the Retainer. Remove the (15) Valve and
(14) Filter from the bore in the (13) Shaft Balancer. If
the Retainer and Valve were not damaged, they can
be reused. However, the Filter should be replaced on
re-assembly.
