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 Sunward?

The current published data covers 15 systems and 1054 hose records. Systems with more listed records include: SWE155F · Control Valve (26 hoses), SWE150E · Control Valve (25 hoses), SWE150W · Control Lever (24 hoses), SWE135E-3H · Control Valve (21 hoses), SWE135E-3H · Control Lever (20 hoses), SWE150W · Control Valve (20 hoses).

What is the hose length range for Sunward?

Based on published records with valid lengths, the range is 160–4,240 mm. Open the individual record to verify its installation position and both end fittings before fabrication.

Which hose specifications are common for Sunward?

The most frequent raw specifications in the current published records are: DN6;1SN-04;22.5MPa (475 records), DN8;1SN-05;22.5MPa (204 records), DN20;6SH-12;35MPa (75 records), DN20;1SN-12;12MPa (35 records), DN25;6SH-16;35MPa (34 records). Verify the specification together with length, pressure, and fitting details.

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

Each record keeps the left and right fitting descriptions separate. Current examples: 730502002435: left 公制内螺纹24°锥带O形圈-轻型; right 90°公制内螺纹24°锥带O形圈-轻型; 730502000386: left 公制内螺纹24°锥带O形圈-轻型; right 90°公制内螺纹24°锥带O形圈-轻型; 73050200A081: left 公制内螺纹24°锥带O形圈-轻型; right 45°公制内螺纹24°锥带O形圈-轻型. Open the exact part-number or pipe-number record; do not swap ends based on appearance alone.

Can I locate a Sunward hose by diagram pipe number?

Yes. Current examples with a diagram pipe number are: Pipe No. 46 (730502002435), Pipe No. 27 (73050200A081), Pipe No. 30 (730501000454), Pipe No. 67 (730502010089). 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 "Sunward 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/brands/sunward/

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.
