SHAFT 2095894 - Caterpillar

Before you disconnect any line from the air compressor, purge the system of pressurized air.Failure to purge the pressurized air before you service the air compressor can result in personal injury.
Hot engine components can cause injury from burns. Before performing maintenance on the engine, allow the engine and the components to cool.
Personal injury can result from rotating and moving parts.Stay clear of all rotating and moving parts.Never attempt adjustments while the machine is moving or the engine is running unless otherwise specified.The machine must be parked on a level surface and the engine stopped.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Air Induction System
One of the most important aspects of preventive maintenance is the induction of clean air. The air induction system should be inspected when maintenance is performed to the air cleaner. Check the air induction line to the compressor for leakage. The air for induction must be drawn through the air cleaner and through the air intake pipe. Be sure that the air induction line and the fittings for the air induction line do not have any leaks.Be sure that the air induction line that connects to the air compressor does not have any restrictions. Check the air intake hoses and clamps.Perform the Following Inspections at an Interval of Every 6 Months, 1800 Operating Hours, or 80467 km (50000 miles)
Cooling System
The minimum size for the coolant lines that connect to the air compressor depends on the flow. The minimum size that is recommended is 9.35 mm (0.368 inch) inside diameter. Inspect the port for the air discharge and inspect the line for the air discharge for buildup of carbon. A buildup of carbon may indicate inadequate cooling.Check the coolant lines for restrictions to flow. Check the condition of the coolant lines. Check for leaks or damage due to wear or abrasion. Check the coolant lines for clogging from rust or scale.Check the coolant flow and compare the coolant flow to the specifications for coolant flow.Lubrication System
Check the oil supply line for restrictions to flow. Refer to the Specification section for the value for minimum oil pressure.Air Compressor Drive
Check for noisy operation. Noisy operation may indicate worn drive components. Refer to the Testing and Adjusting section. Check the mounting bolts for the air compressor. Tighten the mounting bolts to the proper torque. Refer to the Specification section for the proper values for torque.Air Compressor and Unloader for the Air Compressor Governor
Test the air compressor and the governor for proper operation. Test the air compressor and the governor for proper setting
