4.Install the Bevel Gear Spacer (49).

5.Clean the threads on the Arbor; apply a film of thread locking compound to the threads. Screw the Bevel Gear Nut (48) onto the Arbor and tighten to 8.5 to 11.5 ft–lb (11.5 to 15.5 Nm) torque. Remove the Arbor from the vise.

6.Grasp the Angle Arbor Housing (43) in leather–covered or copper–covered vise jaws, angle head up. Install the Upper Bearing Spring Washer (46) and Upper Arbor Bearing (47).

7.If replacement of the Mounting Plate Pin (45) is necessary, press a new pin into the Angle Arbor Housing.

a.Thread the Depressed Center Wheel Flange (66 or 68) onto the Arbor against the Autobalancer Assembly.

b.Slide the wheel onto the Arbor against the Depressed Center Wheel Flange.

c.Thread the Depressed Center Wheel Nut onto the Arbor against the wheel and tighten the Nut using the Depressed Center Wheel Spanner Wrench (Part No. D32–26). Tighten the Nut only enough to drive the wheel and prevent slippage.

d.Using a hex wrench, install the Wheel Retaining

Screw (65) in the end of the Arbor.

For Type 27 Mounted Wheels:

a.Install two Depressed Center Wheel Spacers (63) on the Arbor against the Autobalancer Assembly.

b.Thread the wheel onto the Arbor.

c.Using the hex wrench, install the Wheel Retaining

Screw (65) in the end of the Arbor.

For Type 28 Mounted Wheels:

a.Install one Depressed Center Wheel Spacer (63) on the Arbor against the Autobalancer Assembly.

b.Thread the wheel onto the Arbor.
