Workshop guide

Finding the correct hydraulic hose for Caterpillar CAT®318F L Swivel Joint

Start with the machine and route

For Caterpillar CAT®318F L Swivel Joint, 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.

Records to compare

  • 4I-17391,020 mm · DN10;1SN-6;10.4Mpa · 回转接头~
  • 269-95851,190 mm · DN19;6SH-12;42Mpa · 回转接头~分配阀前
  • 269-9920950 mm · DN19;6SH-12;42Mpa · 回转接头~分配阀前

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.
