Frequently Asked Questions

Is an arm cylinder the same as a stick cylinder on a Cat excavator?

Yes, arm cylinder, stick cylinder and dipper stick cylinder all describe the same part on a Caterpillar excavator. It extends and retracts the stick to give the machine its digging reach and force. Broken Tractor lists parts under all three names, so search by your machine model or the Cat part number to find the right one.

What stick cylinder fits a Cat 320C excavator?

Broken Tractor carries more than one arm cylinder for the Cat 320C, including 179-9785 (also fits the 325C) and 204-3615 (also fits the 320C L, 321B and 321C). Because the correct cylinder can depend on the machine's configuration and serial number, match the part number stamped on your old cylinder or confirm fitment before ordering. We also offer a 320C stick cylinder tube (1772598), a rod assembly (1772599) and a seal kit (2590633).

Can I rebuild a Cat excavator stick cylinder instead of replacing the whole cylinder?

Yes, Broken Tractor offers stick cylinder seal kits along with individual tubes, rod assemblies and heads/glands. That lets you repair an existing cylinder rather than buying a complete group. Examples include seal kit 2590633 for the 320C, 321C and 322C, seal kit 2316844 for the 330C, 330D and 336D L, and seal kit 2426840 for the 323D, 325D and 336D2 L.

Which stick cylinder fits a Cat 336D or 330D excavator?

Several stick cylinders cover these machines, including 2898031 (325D L, 330D, 336D, 340D L and more), 357-4702 (330D L, 336D, 336E, 336F L, 340D2 L) and 3751722 (330D, 336D, 336E, 336F, 340F and more). Fitment can change by serial number, so compare the part number on your existing cylinder or call (800) 909-7060 to confirm with the parts team before ordering.

Do you carry stick cylinders for large Cat excavators like the 374F, 385C and 390F?

Yes, Broken Tractor carries stick cylinders for Cat's larger excavators. Options include 3628488 for the 374D L, 374F L and 390F L, 3631685 and 5701981 for the 390D and 390F, 3153375 for the 365C L and 385C, and 3706692 for the 345C through 352F. Match your model and part number to make sure you get the correct cylinder.
