into the spindle pocket with the shaft facing upward.
3. Place the (36) Washer on the (39) Spindle shaft with the curve
of the washer facing out so that the outside diameter of the
washer will contact the outer diameter of the (35) Bearing.
Place the (43) Shim onto shoulder of the Spindle. Place the
(35) 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 the Spindle using the (MPA0208) T-4B Spindle
Bearing Press Tool Top as shown in Fig. 3.
4. Place the (34) Spacer over the (39) Spindle shaft and onto the
face of the (35) Bearing making sure it is on center. Press the
(33) (no seals/shields) Bearing down using the (MPA0208)
T-4B Spindle Bearing Press Tool Top, being careful to make
sure the Shim is still centered on the vertical axis of the Spindle
shaft and Bearing. See Fig. 4.
5. Snap the (32) Retaining Ring onto the end of the (39) Spindle
Assembly, making sure it is completely snapped into the
groove. Place the Spindle Assembly into the bore of the (31)
Mini Random Orbital Head. Secure the (37) Retaining Ring into
the groove of the Mini Random Orbital Head.

Spindle Bearing and Shaft Balancer Assembly(5.0mm Orbit):
1. Place the (44) Spindle on the base plate of hand press with the
shaft facing upwards. See Figures 5 and 6.
2. Place the (36) Washer on the (44) 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 (35) Bearing.
Place the (43) Shim onto 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

3. Place the (34) Spacer over the (44) Spindle shaft and onto the
face of the (35) Bearing making sure it is on center. Press the
(no seals/shields) (33) Bearing down using the (MPA0208) T-4B
Spindle Bearing Pressing Tool Top, being careful to make sure
the Spacer is still centered on the vertical axis of the Spindle
shaft and Bearing. See Figure 7. Note: When the Spindle
Assembly is done correctly, the Bearings will rotate freely but
not loosely and the Spacer can be moved but will not slide or
move by gravity.
4. Snap the (32) Retaining Ring onto the (44) Spindle Assembly
making sure it is completely snapped into the groove. Set the
Spindle Assembly aside.
5. Apply a pin head size drop of #271 Loctite® or equivalent to
the outside diameter of each of the bearings on the Spindle
Assembly. Spread the drop of bearing locker around both bear-
ings until distributed evenly. Caution: Only a very small amount
of bearing locker is needed to prevent rotation of the bearing
OD. Any excess will make future removal difficult. Place the
Spindle Assembly into the bore of the (42) Shaft Balancer and
secure with the (37) Retaining Ring. Caution: Make sure that

the Retaining Ring is completely snapped into the groove in
the Shaft Balancer. Allow the adhesive to cure.
Motor Assembly:
1. Place the (41) Dust Shield onto the shaft of the (14) Motor
Shaft or (42) Shaft Balancer.
2. Use the larger end of the T-13 Bearing Press Sleeve to Press
the front (10) Bearing (with 2 Shields) onto the shaft of the (14
or 42) Motor Shaft / Shaft Balancer.
3. Slide the (9) Front Endplate with the bearing pocket facing
down onto the Motor Shaft / Shaft Balancer. Gently press
the Front Endplate onto the Bearing using the larger end of
