- 1. Lubricate the cutter clutch drive shaft bearings.
- 2. Lubricate the cutter slip joint drive shaft.
- 3. Check the engine air inlet and exhaust systems.
- 4. Service the compressed air system.
Lubricate those points shown in the service chart.
Lubricating The Cutter Clutch Drive Shaft Bearings
 |
INADVERTENT ENGAGEMENT OF THE CUTTER COULD CAUSE PERSONAL INJURY. SHUT THE ENGINE DOWN, LOCK THE CUTTER CONTROL AT "OFF", AND REMOVE THE KEY FROM THE IGNITION SWITCH. |
 |
- 1. Remove the plug from the clutch adaptor.
- 2. Apply lubricant through the fitting until lubricant flows from the hole from which the plug was removed.
- 3. Reinstall the plug.
Lubricating The Cutter Slip Joint Drive Shaft
The slip joint drive shaft has two universal joints (U-joints) and a sliding spline section. Each U-joint has four bearings. All four bearings and the sliding spline section must be properly lubricated if trouble is to be avoided.

INADVERTENT STARTING OF THE ENGINE COULD CAUSE PERSONAL INJURY. SHUT THE ENGINE DOWN AND REMOVE THE KEY FROM THE IGNITION SWITCH. |
|
To ensure proper lubrication of all four bearing assemblies in the universal joints, it is essential that lubricant be added until it appears at all journal cross bearing seals. This assures removal of dirt particles and other contaminants that may find their way into the bearings and indicates that the bearings are fully lubricated.
Do not assume that bearing cavities have been filled with new lubricant unless flow is noticed around all four bearing seals!
The journal cross seals are designed to relieve. However, if not all the seals "pop" when being lubed, move the drive shaft laterally in all four directions and pull or push on the drive shaft in the direction opposite to the journal cross seal not relieving, while lube gun pressure is being applied to the lubrication fitting. An increase in line pressure may also be necessary.
To ensure proper lubrication of the sliding spline section, apply grease gun pressure to the lubrication fitting until lubricant appears at the pressure relief hole in the welch plug at the sleeve end of the spline.
Then cover the pressure relief hole with a finger and continue to apply grease until it appears at the sleeve yoke seal.
Checking The Engine Air Inlet And Exhaust Systems
|
HOT EXHAUST DUCTING CAN CAUSE SERIOUS BURNS. INADVERTENT STARTING OF THE ENGINE COULD CAUSE PERSONAL INJURY. SHUT THE ENGINE DOWN, REMOVE THE KEY FROM THE IGNITION SWITCH AND ALLOW THE ENGINE TO COOL. |
|
With the engine shut down, check all clamps, bolts and ducting on the engine air inlet and exhaust systems. Service as necessary to prevent any leaks and to ensure that the air cleaners are securely mounted.
Servicing The Compressed Air System
|
HOT EXHAUST DUCTING CAN CAUSE SERIOUS BURNS. INADVERTENT STARTING OF THE ENGINE COULD CAUSE PERSONAL INJURY. SHUT THE ENGINE DOWN, REMOVE THE KEY FROM THE IGNITION SWITCH AND ALLOW THE ENGINE TO COOL. A WEAK FITTING OR LINE UNDER AIR PRESSURE COULD FALL WITH EXPLOSIVE FORCE AND CAUSE PERSONAL INJURY. COMPLETELY DISCHARGE THE AIR PRESSURE BEFORE ATTEMPTING TO REPAIR ANY LEAKS. |
|
- 1. Shut the engine down and check air distribution system for leaks. Repair any leaks found.
- 2. Clean the finned cooling surfaces of the compressor.
