Caterpillar 325 LN FAQ

The Caterpillar 325 LN is a long, narrow-undercarriage version of the first-generation Cat 325 crawler excavator, used to dig, trench, and load material on construction projects. It was built in the 1990s. HCI carries replacement hydraulic cylinders and parts to keep it working.

Every cylinder and part on this page lists its OEM cross-references, so you can match them against the numbers on your old unit. Still unsure? Call our team at 888-771-1894 to confirm fitment — have your serial or the number on the old cylinder ready — or browse the full Caterpillar catalog to find your model.

Any item that shows the FASTSHIP logo and is marked In Stock ships the same day when you order by 12:00 PM CST, Monday through Friday.
