Workshop guide

Finding the correct hydraulic hose for Hitachi ZX330LC

Start with the machine and route

For Hitachi ZX330LC, identify the exact model and hydraulic system on the machine first. A part number or diagram pipe number is the fastest way to narrow a replacement hose; if neither is visible, compare the installation route and the existing hose.

Read the dimensions before cutting

Check whether a listed dimension is finished assembly length, hose-only length, or cut length. These are not interchangeable. Confirm hose specification and pressure rating, then compare both ends separately: thread, sealing seat, size, angle, and orientation.

Records to compare

  • 46272763,850 mm · DN10;1SN-06;18MPa · 行走踏板~分配阀上右
  • 43983673,830 mm · DN5;2层纤维-3;14MPa · Left boom-cylinder grease line
  • 44565571,800 mm · DN10;1SN-06;18MPa · 左手柄~中转接头

Use the drawing as a location check

Where an installation drawing or manual figure is available, match its callout to the part number and physical route. A hydraulic circuit diagram explains connections but does not show the exact routing of a hose on the machine. Take the old hose or clear end-fitting photographs to the workshop if any dimension is missing.

Based on current published data

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 ZX330LC?

The current published data covers 16 systems and 240 hose records. Systems with more listed records include: Attachments – Breaker (36 hoses), Control Lever (31 hoses), Control Valve (29 hoses), Swivel Joint (25 hoses), Attachments (21 hoses), Attachments – Quick Coupler (19 hoses).

What is the hose length range for Hitachi ZX330LC?

Based on published records with valid lengths, the range is 230–9,100 mm. Open the individual record to verify its installation position and both end fittings before fabrication.

Which hose specifications are common for Hitachi ZX330LC?

The most frequent raw specifications in the current published records are: DN10;1SN-6;7Mpa (48 records), DN10;1SN-06;18MPa (43 records), DN6;1SN-04;22.5MPa (28 records), DN25;4SH-16;34.5Mpa (17 records), DN10;2SN-6;34.5MPa (16 records). Verify the specification together with length, pressure, and fitting details.

How can I identify the left and right hose fittings for Hitachi ZX330LC?

Each record keeps the left and right fitting descriptions separate. Current examples: 4627276: left 美制内螺纹74°内锥; right 美制内螺纹74°内锥; 4398367: left 美制内螺纹37°内锥; right 90°公制卡套式; 4456557: 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 ZX330LC hose by diagram pipe number?

Yes. Current examples with a diagram pipe number are: Pipe No. 4 (4627276), Pipe No. 22 (4398367), Pipe No. 20 (4456557), Pipe No. 0 (4390646). Open a record to compare its installation position with the linked manual page.

Optional cross-check

Ask an AI search tool to check this repair data

The question is already written for this machine or hose. Use a tool with web search enabled; treat its answer as a starting point and verify on the machine.

See the exact question being sent
I am checking hydraulic hose repair information for "Hitachi ZX330LC 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/zx330lc--5a583333304c43/

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.
