Workshop guide

Finding the correct hydraulic hose for Caterpillar CAT®319D

Start with the machine and route

For Caterpillar CAT®319D, 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.

  • 199-19651,750 mm · DN13;1SN-8;10.4Mpa · 进回油阀~
  • 212-5403300 mm · DN10;1SN-6;10.4Mpa · 电磁阀(分配阀左下)~过渡阀块(分配阀右下)

Manufacturer references to compare

  • 087-65832,530 mm · 0.38 in ID · Thermoplastic Reduced Outside Diameter Hose

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.

Which systems and hoses are currently listed for Caterpillar CAT®319D?

The current published data covers 11 systems and 74 hose records. Systems with more listed records include: Control Lever (18 hoses), Control Valve (16 hoses), Solenoid Valve (9 hoses), Hydraulic Pump (8 hoses), Attachments (8 hoses), Grease Lines (5 hoses).

What is the hose length range for Caterpillar CAT®319D?

Based on published records with valid lengths, the range is 300–3,100 mm. Open the individual record to verify its installation position and both end fittings before fabrication.

Which hose specifications are common for Caterpillar CAT®319D?

The most frequent raw specifications in the current published records are: DN10;1SN-6;10.4Mpa (46 records), DN10;-6;10.3Mpa (10 records), DN13;1SN-8;10.4Mpa (5 records), DN10;1SN-6;15.7Mpa (2 records), DN10;6SH-6;42Mpa (2 records). Verify the specification together with length, pressure, and fitting details.

How can I identify the left and right hose fittings for Caterpillar CAT®319D?

Each record keeps the left and right fitting descriptions separate. Current examples: 4I-0800: left American female thread, flat-face seal; right 90° elbow, American female thread, flat-face seal; 199-1965: left American female thread, flat-face seal; right American female thread, flat-face seal; 212-5403: 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®319D hose by diagram pipe number?

Yes. Current examples with a diagram pipe number are: Pipe No. 1 (4I-0800), Pipe No. 33 (199-1965), Pipe No. 5 (212-5403), Pipe No. 24 (087-5783). Open a record to compare its installation position with the linked manual page.

Which manufacturer hose part numbers are listed for Caterpillar CAT®319D?

The manufacturer reference currently lists 1 hose part numbers, including 087-6583. Use the exact part number as the first lookup key.

What finished hose lengths are published for Caterpillar CAT®319D?

The published manufacturer references range from 2,530 mm. Match the length to the exact part number and machine before ordering or fabrication.

Do the manufacturer references include both end fittings for Caterpillar CAT®319D?

No. These reference rows provide part number, finished length, hose inside diameter, and hose type or service class where published. Confirm both end fittings on the removed hose or an applicable parts drawing.

Optional cross-check

Ask an AI search tool to check this repair data

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.

See the exact question being sent
I am checking hydraulic hose repair information for "Caterpillar CAT®319D 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-174-319d--43415426233137343b33313944/

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.
