All PM Level 3 maintenance is to be performed at the intervals specified in the Maintenance Management Schedule.Before proceeding with PM Level 3 maintenance, perform all PM Level 2, PM Level 1 and Daily maintenance requirements. You must read and understand the warnings and instructions contained in the Safety section of this manual before performing any operation or maintenance procedures.Air Compressor
Rebuild or Exchange
Visually check for fluid leaks.Our recommendation to maintain your air compressor before it fails will be less costly than repairing the air compressor after failure.If the engine is operated until the air compressor fails, additional damage to the engine could result. For example: A failed air compressor could contaminate the engine oil with particles of materials since engine oil also lubricates the air compressor. The circulation of these engine oil with particles of materials since engine oil also lubricates the air compressor. The circulation of these contaminates through the engine lubricating system could damage the engine's main and connecting rod bearings.Maintenance Options
Repair Kits - These useful kits can be obtained from your Caterpillar dealer. These kits include all the necessary parts, special tools and instructions to repair your air compressor in either your own maintenance shop or at your servicing dealer's facility. Repair kits simplify parts ordering, help speed repairs and reduce parts cost. Exchange - This is a cost cutting service that permits exchanging a worn air compressor for a dealer or OEM factory rebuilt air compressor on an over-the-counter basis. They are available when needed at a substantial savings in both time and money. New - Replace with a new air compressor.Caterpillar Recommendation
The most cost effective repair option is to rebuild the air compressor with a repair kit that can be obtained from your Caterpillar dealer.Refer to the Service Manual for your engine to remove and install the air compressor.Turbocharger
Rebuild or Exchange
The cost incurred to maintain your turbocharger before failure as recommended could be significantly less than if you wait until your turbocharger fails.By maintaining your turbocharger before failure, you will minimize unscheduled downtime and reduce the chances for potential damage to other engine parts. When you reduce the risk of unscheduled downtime and costly repairs, you conserve cash that can be budgeted for use more profitably elsewhere.If you choose to operate your engine until the turbocharger fails, your repair costs could be as much as twenty-five times or more compared to the repair before failure cost. This excessive cost is due to additional engine damage that could have been prevented.If the engine is operated until the turbocharger fails, severe damage to the turbocharger's compressor wheel and/or engine could result.For example: severe damage to the turbocharger compressor wheel could cause parts from the compressor wheel to enter the engine cylinder that could result in cracks in the cylinder head and cause additional damage to the piston, a piston seizure orother potential damage to valves and cylinder head.Our recommended maintenance intervals for performing preventive maintenance on your turbocharger are based on experience and gathered
