Undercarriage Parts by Machine: Models, Specs and What Fits
Browse rubber track product information.
Most undercarriage orders start with a machine, not a part: the model, the serial, and then the number. This page is the machine index - how parts are identified by brand and model, and where to check specifications before ordering. It supports the excavator undercarriage parts guide and the component guides it links to.
By brand
Kobelco: SK16MSR parts, buying SK25SR parts online, SK27SR-3 parts, 13SR options and SK005 parts.
Hitachi: ME15 parts, EX10U parts, durable EX10U parts, what fits the EX30UR-2C and commonly replaced EX60URG parts.
Takeuchi, Case and Terex: Takeuchi TB045 parts, factory-compatible Case CX28 parts and Terex HR4A parts.
IHI and the compact brands: choosing IHI 10Z parts, finding reliable IHI 10Z parts, IHI serial number lookup, CFG STE35SR features and AGT mini excavator parts.
Identifying a part before you order
Identifying KBA1141 parts and their origin, replacement options for KBA1141 components, the RD148-21700 and what the Kubota RD809-21300 is used for show the part-number-first approach; origin and quality checks matter when a number is shared across suppliers.
The machine's own specifications
Sometimes the question is the machine rather than the part. What a Cat 303.5 weighs, Kobelco excavator weights, which engines Kobelco uses, the Kobelco 35 price, the most popular Cat model, the oldest Cat excavator, the specs that matter on a mini skid steer, 12x16.5 skid steer tyres and how long a Bobcat mini excavator lasts cover that ground.
Broader machine questions
Whether Chinese loaders meet CE and EPA standards, what Terracut is, what Ashtrak is and what Contrax offers are the wider machine-and-supplier questions that come up alongside parts.
FAQs
How do I find parts for an uncommon machine?
Start from the part number on the machine, then cross-reference by model and serial. Where the number is not visible, the machine's parts book for that serial is the next source.
Are Chinese-made parts acceptable?
It depends on the specification, not the country. Ask for the dimensions and the material standard and compare them with the original.
Where does this fit in the guide set?
This page is the machine index. The component guides - tracks, rollers, idlers, sprockets, pads, link kits - are linked from the excavator undercarriage parts guide.
Guides in this cluster
Three sub-guides go deeper than this page can. Undercarriage components explained covers what the assembly is made of and how the parts differ by brand; excavator parts by size and type cuts the same question by machine class and application; and undercarriage parts sourcing covers buying, wholesale, dealer programmes and getting parts fast.
