Excavator Parts Catalog
This catalogue lists the OEM part numbers we hold for excavator rubber parts, with the machine each number fits. Every number below is a live part in our range and links to its product page. If your number is not listed, send it to us: we hold numbers that are not yet published here.
How to use this catalogue
- Find your OEM part number in the table below (Komatsu numbers look like 20Y-03-42250, Caterpillar like 230-7800, Hitachi like 3055716).
- Check the machine model in the same row matches yours. Where a model has more than one engine variant, the engine code is shown in brackets and the part is not interchangeable between them.
- Open the product page, or send us the number with your machine serial number range and we will confirm the fitment.

Frequently asked questions
Why does the same machine appear under several part numbers?
Because the cooling and mounting parts change within a model series. A Komatsu PC200-6 with the 6D95 engine takes a different lower water hose from the PC200-6 with the 6D102 engine, and the numbers are not interchangeable. Always match on the engine code as well as the model.
My part number is not in the table. Can you still supply it?
Send it to us. This catalogue covers the numbers we have published product pages for. We hold additional numbers, and we can cross reference Komatsu, Caterpillar, Hitachi, Kobelco and Kato numbering.
Do you have a downloadable version?
The table above is the catalogue. It prints from the browser, and we will send a PDF copy with your quotation if you need one for your records.
Are prices shown?
Not in the catalogue, because price depends on quantity, packing and shipping destination. Send your part list and quantity and we will quote.
