Workshop guide

Finding the correct hydraulic hose for Caterpillar CAT®320C U

Start with the machine and route

For Caterpillar CAT®320C U, 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.

Read the dimensions before cutting

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.

Records to compare

  • 207-66412,500 mm · 13II · Installation route — English review pending

  • 175-61211,490 mm · 25II · Installation route — English review pending

Use the drawing as a location check

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

Common Repair Questions

Questions appear only when a published record or linked PDF page provides the answer.

What is the hose length range for Caterpillar CAT®320C U?

Based on published records with valid lengths, the range is 1,230–2,500 mm. Open the individual record to verify its installation position and both end fittings before fabrication.

Which hose specifications are common for Caterpillar CAT®320C U?

How can I identify the left and right hose fittings for Caterpillar CAT®320C U?

Each record keeps the left and right fitting descriptions separate. Current examples: 207-6641: left 13/16″ 0°; right 13/16″ 0°; 184-9285: left 11/16″ 0°; right 11/16″ 80°; 175-6121: left 1 7/16″ 0°; right 1 7/16″ 90°. Open the exact part-number or pipe-number record; do not swap ends based on appearance alone.

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.
