Parts and Product Categories
We source and quote steel and rubber undercarriage, bolt-on rubber pads, rollers, idlers, sprockets, track chains and shoes; bucket teeth, adapters, side cutters, pins, retainers and cab glass. Products shown online represent available catalog categories, but stock status, lead time and compatibility can change by part number and application.
Shop undercarriage and rubber-track products, bucket teeth and adapters, or excavator cab glass.
Model, Serial Number and Fitment Guidance
Before ordering, provide the full PC model, dash series and serial number, LC/US/MR configuration, track width and pitch, link count, bucket or coupler details and any OEM or casting number. A model decal alone is not enough when a manufacturer revised a machine within the same family. For undercarriage, measure both sides and inspect mating components; for ground-engaging tools, confirm the complete edge, adapter or holder system.
Availability, Shipping and Quote Support
Some products can be purchased online, while oversized, heavy or application-specific parts may require a freight or special-order quote. Shipping method, cost and lead time depend on product weight, dimensions, destination and supplier availability. We will confirm compatible options and current availability before finalizing a quote. Review our shipping and returns information, submit a Part Finder Request for identification help, or request pricing and availability. Photos and measurements often prevent delays.
Komatsu Excavator Parts FAQs
Can a PC model use more than one track configuration?

What should I send for Komatsu bucket tooth fitment?
Send photos of the tooth and adapter, pocket width and height, pin or locking style, bucket width and the machine model and serial number.
