BRACKET 1313255 - Caterpillar

Alternate Procedure
Personal injury can result from hydraulic oil pressure and hot oil.Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system.Make sure all of the attachments have been lowered, oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.
Follow this procedure if a 4C-9710 Hand Pump is not available.
Release the hydraulic system pressure. Refer to Testing and Adjusting, "Hydraulic System Pressure - Release" for the correct procedure.
Raise the cab. Refer to the Operation and Maintenance Manual for your machine.

Install the 8T-0855 Pressure Gauge to the charge pressure tap (4) with a 177-7861 Hose .
Lower the cab.
Sit in the operator's seat. Fasten the seat belt. Lower the armrest.
Start the engine and run the engine at LOW IDLE.
Look at the pressure gauge. The pressure should be 3100 200 kPa (450 29 psi) within 15 seconds after start-up. If the pressure is low, stop the engine immediately. Check the hydraulic oil level in the tank. Determine the cause for low charge oil pressure before you restart the engine.Note: If charge pressure is not reached within 15 seconds, damage to the hydrostatic system will occur. Do not allow the hydrostatic system to operate with incorrect charge system pressures.Flushing The Hydrostatic System
Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact skin.
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 Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
Flushing of the entire hydrostatic system should be performed after a failure of a component or the replacement of a component.Note: If the oil becomes contaminated, premature component failure could result. Contaminated oil can also contribute to overheating. Use the following procedure to flush the oil in the system.Flush the Drive Lines
Block the machine. Raise the cab. Refer to the Operation and Maintenance Manual for your machine.
