Filling Motor Oiler
Never allow the oiler bowl to become empty. The starting motor will be damaged by lack of proper lubrication.
The vanes of the starting motor are lubricated with a fine oil mist from the motor oiler while the motor is operating.When the oiler bowl becomes half empty, remove the oil filler plug and fill the bowl with clean oil. Refer to the Lubrication and Maintenance Chart for proper oil.Adjusting Oiler Feed
If necessary, adjust the oiler feed to release approximately four drops of oil per minute into the starting motor air stream.1. Be sure the fuel supply to the engine is turned off.2. Pull up on the air start control lever and crank the engine.3. Count the drops of oil released per minute into the air stream.a. Turn the valve needle (the uppermost knob is the oiler) counterclockwise to increase the number of drops per minute.b. Turn the valve needle clockwise to decrease the number of drops per minute. Drip rates should only be made under an average steady flow condition. Once established, the lubricator will automatically adjust the drip rate proportionally to variations in air flow.Servicing Oiler Bowl
To service the oiler bowl:1. Shut off the air supply to the starter control valve.2. Open the drain valve at the bottom of the bowl. This valve depressurizes the bowl and allows oil to drain.3. Remove the bowl and clean using warm water only.4. Dry the bowl. Inspect for cracks. Replace if necessary.5. Install bowl and close the drain valve.6. Fill bowl with clean oil. Refer to the lubrication and maintenance chart for proper oil.7. Turn on the air supply to the starter control valve.Clutch
Check - Adjust if Necessary
While engaging the clutch to pick up the load, check the clutch adjustment. The clutch should engage with a hard push and distinct snap. If engagement is "soft," adjust the clutch.1. Stop the engine and remove the clutch inspection cover. 2. Turn the clutch until the lock pin, engaged in the locking ring, is visible.3. Pull the lock pin out and rotate the locking ring clockwise until the lock engages the next notch. 4. Test the clutch adjustment. If still too "soft," rotate the ring to the next notch. If the adjustment is too tight, turn the ring back one notch.5. Install the cover.Glow Plugs
Inspect - Replace If Necessary
1. Disconnect the wire lead from the glow plug terminal on the HEAT-START switch.2. Install an ammeter with a capacity of over 75 amps, in a series, between the disconnected lead and the terminal on the HEAT-START switch.3. Turn HEAT-START switch to HEAT.4. Observe the ammeter. Each 12 volt glow plug draws approximately 12.5 amperes and each 24 volt glow plug draws approximately 6.5 amperes. The ampere draw of one glow plug multiplied by the number of engine cylinders will be the total ampere draw of the glow plugs in the engine. A low reading indicates one or more defective glow plugs.5. If a defective glow plug is indicated, disconnect one glow plug lead at a time.6. Turn switch to the HEAT position. Observe the ammeter. Reconnect the lead.7. The glow plug that does not change the reading on the ammeter, when the switch is turned on, is the defective glow plug.Installing Glow Plugs
1. Disconnect the lead wire at the defective glow plug.2. Remove the defective glow plug.3. Apply anti-seize compound to the threads of the new glow plug.4. Install the new glow plug and tighten to a torque of 45 to 50 N m (10 to 12 lbs ft).5. Turn the HEAT-START switch to the HEAT position and observe the ammeter reading.6. Release the switch.7. Install the lead wire.8. Turn the HEAT-START switch to the HEAT position. The reading should be increased. If the reading is the same, check the glow plug wiring.9. Disconnect the test ammeter.
