Caterpillar 330-A FAQ

The Caterpillar 330-A is the first-generation Cat 330, a large hydraulic crawler excavator used for digging, trenching, and mass excavation on construction and earthmoving projects. It was built in the 1990s as part of Cat’s original 300-series excavator line. 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.
