The current published data covers 15 systems and 75 hose records. Systems with more listed records include: Control Lever (16 hoses), Attachments (14 hoses), Swivel Joint (11 hoses), Control Valve (5 hoses), Hydraulic Tank (4 hoses), Pedal (4 hoses).

What is the hose length range for Hitachi ZX240?

Based on published records with valid lengths, the range is 400–4,350 mm. Open the individual record to verify its installation position and both end fittings before fabrication.

Which hose specifications are common for Hitachi ZX240?

The most frequent raw specifications in the current published records are: DN10;1SN-06;18MPa (24 records), DN6;1SN-04;22.5MPa (16 records), DN6;1SN-4;7Mpa (7 records), DN10;1SN-6;7Mpa (5 records), DN19;4SP-12;38Mpa (5 records). Verify the specification together with length, pressure, and fitting details.

How can I identify the left and right hose fittings for Hitachi ZX240?

Each record keeps the left and right fitting descriptions separate. Current examples: 4462262: left 美制内螺纹37°内锥; right 45°美制内螺纹37°内锥; 4437938: left 美制内螺纹74°内锥; right 45°美制内螺纹74°内锥; 4254418: left American female thread, flat-face seal; right 90° elbow, American female thread, flat-face seal. Open the exact part-number or pipe-number record; do not swap ends based on appearance alone.

Can I locate a Hitachi ZX240 hose by diagram pipe number?

Yes. Current examples with a diagram pipe number are: Pipe No. 28 (4462262), Pipe No. 5 (4437938), Pipe No. 0 (4254418), Pipe No. 23 (4452037). Open a record to compare its installation position with the linked manual page.
