Excavator Undercarriage Parts: Buying Guides by Brand

Each excavator brand has its own part-number conventions, its own series of models and its own common failure points, and a guide written for one is only partly useful on another. This page collects the brand guides. It sits beneath the machine index at undercarriage parts by machine.

The brand buying guides

Cat excavator undercarriage parts, Komatsu PC series, Kubota KX and U series, Hitachi ZX series, John Deere compact excavators, Case CX series, Doosan DX series, Volvo EC series, Takeuchi TB series and Kobelco SK series cover the common machines.

The wider brand references

The Caterpillar components guide and the Cat D5 to D8 dozer guide cover the crawler side; on the compact end, the best Kubota undercarriage parts, which Kubota parts you need and the KX161-3 specifics cover one brand in depth, with steel undercarriages on Kubota machines for the alternative.

Sizing a specific machine

Optimizing Cat 320 parts, sizing Komatsu PC200 parts, rebuilding a Volvo EC210 undercarriage, what fits a Doosan DX140LC and the mini excavator parts map cover individual machines.

FAQs

Why do brands need separate guides?

Because part numbers, series and failure patterns differ. A roller that fits one 5-tonne machine rarely fits another.

Should I use one supplier for several brands?

Where the supplier covers your fleet, yes - the ordering and warranty become simpler, which is the consolidation argument covered in the purchasing guide.
