Pinion Clearance Adjustment (Delco-Remy)
Whenever the solenoid is installed, make an adjustment of the pinion clearance. The adjustment can be made with the starting motor removed.1. Install the solenoid without connector (1) from the MOTOR connection (terminal) on solenoid to the motor.2. Connect a battery, of the same voltage as the solenoid, to the terminal (2), marked SW.3. Connect the other side of battery to ground terminal (3).4. Connect for a moment, a wire from the solenoid connection (terminal) marked MOTOR to the ground connection (terminal). The pinion will shift to crank position and will stay there until the battery is disconnected.
CONNECTION FOR CHECKING PINION CLEARANCE
1. Connector from MOTOR terminal on solenoid to motor. 2. SW terminal. 3. Ground terminal.5. Push the pinion toward commutator end to remove free movement.6. Pinion clearance (6) must be .36 in. (9.1 mm).7. Pinion clearance adjustment is made by removing plug and turning nut (4).

PRESSURE REGULATING VALVE (TYPICAL ILLUSTRATION)
1. Adjustment screw. 2. Regulator inlet. 3. Regulator outlet.Use the following procedure to check and adjust the pressure regulating valve.1. Drain the line to the pressure regulating valve or drain the air storage tank.2. Disconnect the regulator from the starter control valve.3. Connect an 8M2885 Pressure Gauge to the regulator outlet.4. Put air pressure in the line or tank.5. Check the pressure.6. Adjust the pressure regulating valve to 150 psi (10.5 kg/cm2) (1034 kPa).7. Remove the air pressure from the line or tank.8. Remove the 8M2885 Pressure Gauge and connect the air pressure regulator to the line to the air starting motor.Air Starting Motor (Ingersoll-Rand)
Lubrication
For temperatures above 32° F (0° C), use a good quality SAE 10 motor oil.For temperatures below 32° F (0° C), use diesel fuel.Always use an air line lubricator with these Starters.Disassembly
Before disassembling an SM450 Starter, always mark adjacent parts on the Motor Housing Cover (1), Motor Housing (7), Gear Case (52), Gear Case Cover (30) and Drive Housing (48) so that these members can be located in the same relative position when the Starter is reassembled.Do not disassemble the Starter any further than necessary to replace a worn or damaged part. Do not remove any part which is a press fit in or on a subassembly unless the removal of that part is necessary for replacement or repairs. Do not press any needle bearing or bushing from a bearing recess unless a new bearing or bushing is to be installed. These members are always damaged during the removal process.Always have a complete set of gaskets, vanes, seals and O-rings on hand before starting any overhaul of an SM450 Starter. Never reuse old gaskets, seals or O-rings.Never wash a Bendix drive in kerosene or other solvent. Doing so will remove or dilute the factory applied lubricant within the drive clutch.Motor Assembly
Assemble the Multi-Vane motor as follows:1. Clean the tapered hub on the Rotor (13) and the tapered socket in the Rotor Pinion (24). Apply a small quantity
