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 EX100M-3?

The current published data covers 12 systems and 51 hose records. Systems with more listed records include: Boom Assembly (12 hoses), Control Valve (10 hoses), Control Lever (9 hoses), Attachments – Breaker (7 hoses), Pedal (3 hoses), Grease Lines (3 hoses).

What is the hose length range for Hitachi EX100M-3?

Based on published records with valid lengths, the range is 260–2,750 mm. Open the individual record to verify its installation position and both end fittings before fabrication.

Which hose specifications are common for Hitachi EX100M-3?

The most frequent raw specifications in the current published records are: DN10;1层纤维-6;14MPa (19 records), DN6;2层纤维-4;14MPa (7 records), DN10;1SN-6;7Mpa (6 records), DN12;4SP-08;34.5Mpa (3 records), DN12;4SP-8;34.5Mpa (3 records). Verify the specification together with length, pressure, and fitting details.

How can I identify the left and right hose fittings for Hitachi EX100M-3?

Each record keeps the left and right fitting descriptions separate. Current examples: 4288438: left 英制内螺纹30°外锥; right 英制锥形外螺纹30°内锥; 4260263: left American female thread, flat-face seal; right American female thread, flat-face seal; 4323030: 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 EX100M-3 hose by diagram pipe number?

Yes. Current examples with a diagram pipe number are: Pipe No. 22 (4288438), Pipe No. 13 (4260263), Pipe No. 4 (4323030), Pipe No. 22 (4297977). Open a record to compare its installation position with the linked manual page.

I am checking hydraulic hose repair information for "Hitachi EX100M-3 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/ex100m-3--45583130304d2d33/

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.
