Information:

Pinion Clearance Adjustment (Delco-Remy)
CONNECTION FOR CHECKING PINION CLEARANCE
1. Connector from MOTOR terminal on solenoid to motor. 2. SW terminal. 3. Ground terminal.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.
PINION CLEARANCE ADJUSTMENT
4. Shaft nut. 5. Pinion. 6. Pinion clearance.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).Shutoff Solenoid
Two checks must be made on the engine to give proof that the solenoid adjustment is correct.1. The adjustment must give the piston enough travel to move the sleeve control shaft to the shutoff position.2. The adjustment must give the piston enough travel to cause only the "hold in" windings of the solenoid to be activated when the sleeve control shaft held in the fuel closed position. Use a thirty ampere ammeter to make sure the plunger is in the "hold in" position. Current needed must be less than one ampere.
ACTIVATE TO RUN
1. Shutoff solenoid. 2. 9L6588 Spring. 3. 3N2835 and 7N9635 Shaft.
ACTIVATE TO SHUTOFF
1. Shutoff solenoid. 4. Distance from face of piston to inside face of shaft (5). 5. 3N2836 and 6N591 Shaft.Air Starting System
Pressure Regulating Valve
PRESSURE REGULATING VALVE (TYPICAL ILLUSTRATION)
1. Adjustment screw. 2. Regulator inlet. 3. Regulator outlet.Use the procedure that follows 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 according to Chart For Air Pressure Setting.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. Each engine application will have to be inspected to get the most acceptable starting results. Some of the factors that affect regulating valve pressure setting are: attachment loads pulled by engine during starting, ambient temperature conditions, oil viscosity, capacity of air reservoir, and condition of engine (new or worn).The advantage of setting the valve at the higher pressures is increased torque for starting motor and faster rotation of engine. The advantage of setting the valve at the lower pressures is longer time of engine rotation for a given reservoir capacity of supply air.Lubrication
Always use an air line lubricator with these Starters.For temperatures above 32° F
