TUBE SPACER 5P1667 - Caterpillar

Do not remove any valve, hydraulic fitting or valve core, nor disassemble any parts until pressure has been released. Failure to release pressure can cause personal injury or death.
The following steps are to release the pressure in the system:a. Shut off engine.b. With operator in seat and bucket on ground, engage selector valve (pilot control) and actuate an implement control lever about ten times to release pressure in hydraulic system.c. Press the relief valve button on the hydraulic tank breather to release the tank pressure.
Hydraulic oil that is under pressure and hot can cause bodily injury. Move the control levers to relieve pressure in the hydraulic system. Let the hydraulic oil become cool before any lines are disconnected in the hydraulic system.
The 5130B Excavator has five switch assemblies (chip detector). One is located on each of the piston pumps (implement) and on the piston pump (swing). All five can be removed and installed using the procedure shown. 1. Position a suitable container under chip detector switch assembly (1) to contain any oil lost for storage or disposal. Disconnect chip detector (1) switch assembly wiring harness (2) at the electrical connection. Remove chip detector switch assembly (1) and the O-ring seal from the piston pump (swing). The following step is for the installation of the switch assembly (chip detector). Check all components for wear or damage and replace if necessary. Apply 1U-6396 O-ring Compound to all O-ring seals prior to installation, if applicable.2. Install chip detector switch assembly (1) and the O-ring seal to the piston pump (swing). Connect chip detector switch assembly wiring harness (2) at the electrical connection.3. Refill the hydraulic system with hydraulic oil. The capacity of the hydraulic system is 1600 L (423 U.S. gal). For correct filling procedures, refer to topic "Lubricant Viscosities and Refill Capacities" in the 5130B Excavator, Operation & Maintenance Manual.
