Workshop guide

Finding the correct hydraulic hose for Caterpillar CAT®318F L Control Valve

Start with the machine and route

For Caterpillar CAT®318F L Control 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.

See all Caterpillar CAT®318F L 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.

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.

For reference only. Confirm the actual hose before fabrication.
