Common Repair Questions
Questions appear only when a published record or linked PDF page provides the answer.
Which systems and hoses are currently listed for Hitachi ZX120?
The current published data covers 15 systems and 106 hose records. Systems with more listed records include: Control Lever (25 hoses), Attachments (22 hoses), Grease Lines (15 hoses), Hydraulic Pump (10 hoses), Attachments – Breaker (6 hoses), Attachments – Quick Coupler (5 hoses).
What is the hose length range for Hitachi ZX120?
Which hose specifications are common for Hitachi ZX120?
The most frequent raw specifications in the current published records are: DN10;1SN-06;18MPa (25 records), DN10;1SN-6;7Mpa (18 records), DN6;1SN-4;7Mpa (15 records), DN6;1SN-04;22.5MPa (11 records), DN5;2层纤维-3;14MPa (6 records). Verify the specification together with length, pressure, and fitting details.
How can I identify the left and right hose fittings for Hitachi ZX120?
Each record keeps the left and right fitting descriptions separate. Current examples: 4441179: left 美制内螺纹37°内锥; right 美制内螺纹37°内锥; 4460593: left 美制内螺纹74°内锥; right 美制内螺纹74°内锥; 4442331: left 美制内螺纹74°内锥; right 美制内螺纹74°内锥. Open the exact part-number or pipe-number record; do not swap ends based on appearance alone.
Can I locate a Hitachi ZX120 hose by diagram pipe number?
Yes. Current examples with a diagram pipe number are: Pipe No. 17A (4441179), Pipe No. 11 (4460593), Pipe No. 29 (4442331), Pipe No. 11 (4285464). Open a record to compare its installation position with the linked manual page.

I am checking hydraulic hose repair information for "Hitachi ZX120 Hose Repair Data". Use web search and cite a source for every factual point. Compare this HoseSeek page with manufacturer manuals and reliable parts documentation: https://www.hoseseek.com/machines/hitachi/zx120--5a58313230/ Verify, where applicable: 1. Exact machine model and any serial-number range. 2. Hydraulic system and installation route. 3. Hose part number and diagram pipe number. 4. Finished length, hose specification, and pressure rating. 5. Both end fittings, including thread, sealing seat, size, and angle. 6. Installation-diagram position and routing. State explicitly what you could not verify. Do not infer a missing dimension or fitting. End with a short on-machine checklist for a hose repair technician.
