Workshop guide
For Caterpillar CAT®M317F Attachments, 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.
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.
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.
Optional cross-check
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.
I am checking hydraulic hose repair information for "509-4741 Hydraulic Hose Replacement 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_f264dd84fea52cc040e4e7d3/ HoseSeek currently shows: part number: 509-4741; diagram pipe number: 6; installation route: Installation route — English review pending; hose specification: DN32;6SH-20;42Mpa; finished length in millimetres: 1380; left fitting: 45° heavy-series flange; right fitting: Heavy-series flange. 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.
