Workshop guide
For Caterpillar CAT®EL200B, 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.
Based on current published data
Questions appear only when a published record or linked PDF page provides the answer.
The current published data covers 3 systems and 6 hose records. Systems with more listed records include: Boom Assembly (4 hoses).
Each record keeps the left and right fitting descriptions separate. Current examples: 085-4610: left American female thread, 37° cone seat; right American female thread, 37° cone seat; 096-4916: left American female thread, flat-face seal; right American female thread, flat-face seal; 099-5589: left American female thread, flat-face seal; right American female thread, flat-face seal. Open the exact part-number or pipe-number record; do not swap ends based on appearance alone.
Yes. Current examples with a diagram pipe number are: Pipe No. 4 (085-4610), Pipe No. 12 (096-4916), Pipe No. 161 (099-5589), Pipe No. 5 (099-5589). Open a record to compare its installation position with the linked manual page.
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 "Caterpillar CAT®EL200B 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/caterpillar/cat-174-el200b--43415426233137343b454c32303042/ 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.
