Ingersoll Rand — Assembly of the Arbor
Repair & overhaul
From a Ingersoll Rand service manual — check it applies to your exact model before use.
Before you start
- Slip the flanges onto the arbor so the keys are opposite each other.
Procedure
- Press the Arbor Bearing (59) onto the Arbor Shaft (56).
- Grasp the Arbor Shaft in a vise, spline end up.
- Install the Bearing Lock Washer (58) and Bearing Locknut (57). Tighten the Locknut snugly, then bend the tangs of the Bearing Lock Washer into the grooves of the Locknut.
- Grasp the Arbor Housing (29) in a vise, guard end up.
- Coat the splines of the Rotor Shaft and Arbor Shaft with 3 to 4 cc of Ingersoll Rand No. 28 Grease and install the Arbor Coupling.
- Place the Wheel Guard (55) onto the Arbor Housing and install the Guard Screw Lock Washers (54) and Guard Screws (53). Tighten to 15 ft-lb (20.3 Nm) torque.
- Install a Wheel Flange (52), Wheel and the other Wheel Flange (52) onto the Arbor (56) with keys opposite each other.
- Hold the arbor with a spanner wrench in the flange pin hole and install the Wheel Nut (51) with an open-end wrench; tighten only sufficiently to drive the wheel and prevent slippage.
- Fill the oil chamber with the recommended oil and insert the Oil Chamber Plug (24). Tighten to 4 ft-lb (5.4 Nm) torque.
