Removal Procedure
| NOTICE |
|---|
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. |

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 to the ground, and the 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. |

- Use the following procedure to release the pressure in the hydraulic system:
- Lower the implements to the ground.
- Shut off the engine.
- Move the control levers through the full travel distance of the levers. This will relieve any pressure in the pilot system.
- Slowly loosen the filler cap on the hydraulic oil tank in order to release the pressure.
- Tighten the filler cap on the hydraulic oil tank.
- The pressure in the hydraulic system has now been relieved. Lines and components can now be removed.
Note: Put identification on all lines, hoses, wires, and tubes for installation purposes. Install a cap or plug on all lines, hoses, and tubes that are disconnected. The caps and/or plugs prevent the loss of fluid and contaminants cannot enter the system.
- Remove clamp (1) that holds the two hose assemblies in place.
