Workshop guide
For Caterpillar CAT®M318 Solenoid Valve, 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 most frequent raw specifications in the current published records are: DN10；1SN-6；15.7Mpa (5 records), DN10；6SH-6；42Mpa (5 records), DN10；2SN-6；33Mpa (2 records), DN13；1SN-8；14Mpa (1 records), DN13；2SN-8；27.5Mpa (1 records). Verify the specification together with length, pressure, and fitting details.
Each record keeps the left and right fitting descriptions separate. Current examples: 131-0957: left 90° elbow, American female thread, flat-face seal; right American female thread, flat-face seal; 123-0062: left American female thread, flat-face seal; right American female thread, flat-face seal; 145-2582: left American female thread, flat-face seal; right 90° elbow, 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. 18 (131-0957), Pipe No. 4 (123-0062), Pipe No. 16 (145-2582), Pipe No. 4 (115-7997). Open a record to compare its installation position with the linked manual page.
