How to choose the correct Komatsu CX20 parts catalog

Match the serial range in the catalog name with the serial number on the machine plate. A book for another range, region or modification may not be the correct version for this CX20.

Which catalog should I use?

Start with the listed book and confirm its model and serial range against the machine plate. If the page shows other variants, compare them before opening the complete catalog.

Can I search by part number?

Yes. Open the interactive catalog and enter the part number as printed in the book. The public page does not silently translate or change the number.

What is available on the public page?

The public page can show the verified model, selected book name, serial range, page and diagram counts, available variants and main section links when those facts exist in K-Part.

When is a subscription required?

Public model information is available without signing in. Opening complete working catalog materials and account features may require an active subscription.
