Finding the correct hydraulic hose for Excavator Hydraulic Hose Directory
Start with the machine and route
For Excavator Hydraulic Hose Directory, 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
- 43867393,000 mm · DN10;2SN-6;34.5MPa · 分配阀左~控制阀(推土铲)
- 4372796310 mm · DN10;1SN-6;7Mpa · 破碎器踏板~过渡阀块(踏板)
- 43511921,800 mm · DN10;1SN-06;7Mpa · 右手柄~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.

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 Excavator?
The current published data covers 22 systems and 37582 hose records. Systems with more listed records include: Attachments (86 hoses), Attachments (85 hoses), Attachments (83 hoses), Control Lever (79 hoses), Control Valve (76 hoses), Attachments (75 hoses).
What is the hose length range for Excavator?
Which hose specifications are common for Excavator?
The most frequent raw specifications in the current published records are: DN6;1SN-04;22.5MPa (6553 records), DN10;1SN-6;7Mpa (4267 records), DN10;1SN-06;18MPa (4243 records), DN10;1SN-6;10.4Mpa (1944 records), DN10;-6;10.3Mpa (1545 records). Verify the specification together with length, pressure, and fitting details.
How can I identify the left and right hose fittings for Excavator?
Each record keeps the left and right fitting descriptions separate. Current examples: 4386739: left 美制内螺纹37°内锥; right 90°美制内螺纹37°内锥; 4372796: left 美制内螺纹37°内锥; right 美制内螺纹37°内锥; 4351192: left 美制内螺纹37°内锥; right 美制内螺纹37°内锥. Open the exact part-number or pipe-number record; do not swap ends based on appearance alone.
Can I locate a Excavator hose by diagram pipe number?
Yes. Current examples with a diagram pipe number are: Pipe No. 1A (4386739), Pipe No. 16 (4372796), Pipe No. 24 (4351192), Pipe No. 0 (4649317). Open a record to compare its installation position with the linked manual page.
Which PDF pages can help locate Excavator hoses?
Available manual references include: Doosan DX140LCR Excavator Parts Manual, page 138 (Fig. 1240 OIL COOLER PIPING(3)); Doosan DX140LCR Excavator Parts Manual, page 182 (Fig. 1330 PILOT PIPING(5); S/N 5001-5226); Doosan DX140LCR Excavator Parts Manual, page 182 (Fig. 1330 PILOT PIPING(5); S/N 5001-5226).

I am checking hydraulic hose repair information for "Excavator Hydraulic Hose Directory". 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/equipment/excavators/ 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.
