Caterpillar 322B LN FAQ

The Caterpillar 322B LN is a long, narrow-undercarriage version of the 322B crawler excavator, used to dig, trench, and load material on confined or transport-restricted sites. It is part of Cat’s B-Series, built in the late 1990s and early 2000s. 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.
