Frequently Asked Questions

What pins and links fit a Cat 330B excavator?

Broken Tractor carries boom links, pins, bushings, and seal kits listed for the Cat 330B. Options include the left link with bolt holes (189-3878), the H link (212-3002), the link-to-dipper pin (189-3922), the bucket linkage pin 189-3923, bushings 137-2819 and 203-7326, and the PV7020 shim and seal kit. Some parts fit the 330B but not the 330BL, so check the listed models on each part before ordering.

Do the Cat 330, 330B, and 330C use the same H link?

Yes, the H link 212-3002 is listed for the 330, 330L, 330B, 330BL, 330C, and 330CL. We also carry matching H-link bushings, including 203-7326 for all of those models and 203-7322 for the 330, 330B, and 330C. Replacing the bushings along with the link can help keep the boom linkage tight.

Is there a shim and seal kit for the Cat 330C excavator?

Yes, Broken Tractor offers the PV7020 shim and seal kit for the Cat 330C and 330CL. The same kit is also listed for the 330, 330B, and 330BL. Pairing it with new pins and bushings during a linkage rebuild helps you get the full service life out of the new parts.

Which bucket link fits a Cat 330 or 330C excavator?

Several bucket links fit the 330 series, and fitment varies by model. For example, 4I4724 is listed for the 330, 330 L, 330B, 330B L, 330C, and 330C L, while 4I4727 and 7Y3546 cover the 330, 330B L, 330C, and 330C L but not the standard 330B. Match the part number from your old link or parts book, or call (800) 909-7060 to confirm the right one for your machine.

Do I need a special tool to replace bushings on a Cat 330 excavator?

A bushing driver makes removing and installing linkage bushings much easier and helps avoid damaging the bore. Broken Tractor offers a steel bushing driver removal and installation tool that is universal, so it works for service on your Cat 330, 330B, or 330C.
