I am checking hydraulic hose repair information for "4377481 Hose Repair Specifications". 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/hoses/hose_35a3f75a99f70a228c64f388/ HoseSeek currently shows: part number: 4377481; diagram pipe number: 1; installation route: Swivel joint → travel motor; hose specification: DN25;4SP-16;32Mpa; finished length in millimetres: 2400; left fitting: American female thread, flat-face seal; right fitting: 90° elbow, American female thread, flat-face seal. 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.
For reference only. Confirm the actual hose before fabrication.
