Yes, this manual provides both the hydraulic pressure specifications and the component layouts necessary for identifying test port locations used during diagnostic and maintenance procedures.
In the General Specifications section, the manual lists detailed pressure values for key components in the hydraulic system. This includes:
- Main relief pressure (normal and power boost)
- Pilot system pressure
- Overload and swing brake valve relief pressures
- Cracking pressures for multiple subsystems (e.g., oil cooler bypass, swing and travel parking brakes)
Additionally, the manual includes labeled component layout diagrams that clearly indicate the position of the pilot pump, pilot relief valve, and both delivery pressure sensors for Pump 1 and Pump 2. These are typically the key locations where pressure measurements and diagnostics are performed using test ports.
Supporting this, the hydraulic system schematics show the complete flow of pressure and return oil through the circuit, allowing technicians to trace hydraulic lines to and from the control valves, actuators, and filters. These diagrams are instrumental in locating where test ports are usually installed or recommended for pressure testing.
For technicians performing system diagnostics or troubleshooting, the manual also outlines how pressure values relate to functional performance, and how to verify or replace components such as pilot valves, regulators, and pressure sensors.
In summary: if you're servicing this model's hydraulic system, this manual gives you all the pressure ratings and visual guidance needed to identify test locations, evaluate system performance, and verify proper operation. For detailed replacement procedures and specific test instructions, refer to the relevant sections within the manual’s hydraulic and component operation chapters.
