Workshop guide

Finding the correct hydraulic hose for Caterpillar CAT®319C Attachments

Start with the machine and route

For Caterpillar CAT®319C 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.

See all Caterpillar CAT®319C systems

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

4I-1025300 mm · DN10；-6；10.3Mpa · 左踏板~进回油阀

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.

How many hoses are currently listed for Caterpillar CAT®319C Attachments?

There are 30 published records. 30 include a length, both end fittings, and a part number or diagram pipe number.

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

Based on published records with valid lengths, the range is 300–5,800 mm. Open the individual record to verify its installation position and both end fittings before fabrication.

Which hose specifications are common for Caterpillar CAT®319C Attachments?

The most frequent raw specifications in the current published records are: DN10；1SN-6；10.4Mpa (12 records), DN10；-6；10.3Mpa (7 records), DN25；6SH-16；42Mpa (5 records), DN19；6SH-12；42Mpa (3 records), DN10；2SN-6；33Mpa (1 records). Verify the specification together with length, pressure, and fitting details.

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

Each record keeps the left and right fitting descriptions separate. Current examples: 087-6583: left American female thread, flat-face seal; right American female thread, flat-face seal; 108-7372: left American female thread, flat-face seal; right 90° elbow, American female thread, flat-face seal; 4I-1025: left 90° elbow, 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®319C Attachments hose by diagram pipe number?

Yes. Current examples with a diagram pipe number are: Pipe No. 2 (087-6583), Pipe No. 4 (108-7372), Pipe No. 9 (4I-1025), Pipe No. 8 (240-5718). Open a record to compare its installation position with the linked manual page.
