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 Caterpillar CAT®317B L?

The current published data covers 14 systems and 75 hose records. Systems with more listed records include: Attachments (14 hoses), Control Valve (12 hoses), Attachments – Quick Coupler (11 hoses), Attachments – Lock Valve (9 hoses), Boom Assembly (8 hoses), Control Lever (5 hoses).

What is the hose length range for Caterpillar CAT®317B L?

Based on published records with valid lengths, the range is 370–4,020 mm. Open the individual record to verify its installation position and both end fittings before fabrication.

Which hose specifications are common for Caterpillar CAT®317B L?

The most frequent raw specifications in the current published records are: DN10;-6;10.3Mpa (17 records), DN6;-4;10.3Mpa (8 records), DN10;1SN-6;15.7Mpa (7 records), DN19;4SP-12;35Mpa (5 records), DN19;6SH-12;42Mpa (5 records). Verify the specification together with length, pressure, and fitting details.

How can I identify the left and right hose fittings for Caterpillar CAT®317B L?

Each record keeps the left and right fitting descriptions separate. Current examples: 172-5926: left American female thread, flat-face seal; right Heavy-series flange; 8E-0081: left American female thread, flat-face seal; right American female thread, flat-face seal; 136-7694: 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.

Can I locate a Caterpillar CAT®317B L hose by diagram pipe number?

Yes. Current examples with a diagram pipe number are: Pipe No. 7 (172-5926), Pipe No. 2 (8E-0081), Pipe No. 2 (136-7694), Pipe No. 3 (117-9097). Open a record to compare its installation position with the linked manual page.

I am checking hydraulic hose repair information for "Caterpillar CAT®317B L 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-174-317b-l--43415426233137343b33313742204c/

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.
