Pressure Regulating Valve Adjustments
The regulator can be adjusted by turning the adjusting screw (1) located on top of the chamber. Disconnect the regulator from the control valve. With the regulator connected to the air supply line, connect an 8M2885 Pressure Gauge to the regulator outlet (3) and check the pressure. In cold weather it may be necessary to raise the pressure delivered by the regulator. The pressure should not exceed 90 to 110 psi (6,2 to 7,7 kg/cm2). After the pressure has been set, install the regulator.

Air Starting Motor Rotor Assembly End Clearance Adjustment
ROTOR ASSEMBLY END CLEARANCE ADJUSTMENT
1. Rotor. 2. Spacer. 3. End plate. 4. Bearing. 5. Shims.
Place shims (5) between the bearing (4) and spacer (2) so there will be .002 in. (0,05 mm) clearance between the rotor (1) and the end plate (3).
Heating the gear will aid installation. Tighten the nut and check the adjustment. Measure end play between rotor and end plate assembly by using a thickness gauge.
If rotor shaft end play is not correct, the thickness gauge is used to determine how many shims (5) should be removed or added to obtain correct clearance. Upon assembly fill gear compartment with lubricant.
