Case CX40B 2010 Parts Catalog

If you are ordering parts for a Case CX40B mini crawler excavator, you need the factory part numbers. Aftermarket catalogs mix up supersessions. I have seen a mechanic order a hydraulic pump seal kit using a third-party number, and it was the wrong size. Wasted a day. This OEM Case CX40B 2010 Parts Catalog from CASE gives you the exact part numbers, exploded views, and supersession history. 799 pages of verified factory data.

Printed in 2010 under Print No. 6-85074, this catalog replaces the earlier edition 6-85073. It covers the CX40B mini crawler excavator in eight languages. You get the same information a CASE dealer uses. No aftermarket guessing.

What 799 Pages of Factory Data Gets You

This catalog is organized by functional groups. You get exploded diagrams for every major system: undercarriage, swing mechanism, engine, hydraulics, electrical, and cab components. Each illustration shows the part number, description, quantity required, and any supersession notes. Page 1 carries the multi-language title; page 2 lists the edition and copyright date. The indexing lets you cross-reference a part number against the illustration quickly.

Need a sprocket for the undercarriage? You will find the exact CASE part number and any later replacements. The catalog uses the single-item numeration method – each part gets a unique reference. Do not trust a generic online search that returns three different numbers. Use this factory source.

Source Validity: OEM Factory Print, Not a Copy

This is an original CASE publication – Copyright © 2010. The information is intended for use by dealers and service technicians. I have seen too many aftermarket parts catalogs that copy the images but change the part numbers. They get the thread pitch wrong on a fitting, and you have a leak. CASE reserves all rights. You are getting the same data that a CASE dealer pulls up on his terminal. No reprints, no third-party editing.

Who Needs This Parts Catalog?

Any shop or owner working on a CX40B. If you are a DIY mechanic trying to rebuild the final drive, you need these part numbers to match the bearing and seal kit. If you run a repair shop, you will save time looking up the correct part instead of ordering three versions. The catalog also includes the supersession chain – if CASE changed a part number after 2010, the old number is listed with the new one. That alone prevents returns.

3 Reasons to Use the Factory Part Numbers

• Accuracy: Every number in this catalog was verified by CASE engineering. Aftermarket catalogs often reuse illustrations from older models. A 2008 CX40B may have different seals than a 2010. This catalog matches your machine by serial number range.
• Time saved: When you order the correct part the first time, you are not waiting for a return and reorder. The exploded views show how components fit together, so you can spot if you need a gasket kit along with the cylinder.
• Safety: Wrong parts in a hydraulic or brake system can cause failures. This catalog ensures you get the correct pressure ratings and thread sizes.

Common Pitfalls When Ordering Parts for the CX40B

Parts catalogs are only as good as the data inside. Many online parts sites use flat-rate listings that omit supersessions. I have seen a shop order a final drive motor using a number that was discontinued and replaced with a different flange pattern. The part arrived, did not bolt up, and they lost a day. This catalog includes the supersession notes directly in the parts list. Always check the “Replace” note on each page. Page 1 shows the catalog replaces print 6-85073. That means parts from the older edition may have changed.

Another trap: assuming a component is the same across the CX40B and CX50B. While some parts are shared, the undercarriage and boom geometry differ. Use the correct model catalog. For related manuals, see CASE CX40B CX50B 2004 Workshop Manual for repair procedures, CASE CX40B CX50B Mini Excavator Operator’s Manual for daily operation, and Case CX160B 2007 Parts Catalog – OEM Undercarriage Hydraulics for a larger machine reference.

Does this catalog include actual torque specs for assembly?

No. This is a parts catalog, not a repair manual. It lists part numbers and exploded views. For torque values, you need the workshop manual. But the parts catalog does tell you which bolts and washers are used, so you can order the correct hardware kit.

Can I use this catalog to order parts for a 2012 CX40B?

The catalog is based on the 2010 release. CASE may have updated parts through service bulletins after that year. The supersession data in this catalog only covers changes up to the print date. For a 2012 machine, check the serial number against the groups in this catalog. Most undercarriage components remained the same, but check the hydraulic pump section.

Are the exploded diagrams resolution enough to read part numbers?

Yes. The PDF is scanned from the original print. Each numbered callout is clear. If you zoom in on a typical 24-inch monitor, you can read every number. Some older digital copies have poor quality; this one is direct from the factory binder.

How do I use the single-item numeration method to find a part?

Each part gets a unique code in the index. Look up the functional group (e.g., Swing Mechanism), find the illustration, and read the number next to the arrow. Cross-check that number in the parts list. If the part is superseded, the list shows the replacement number directly below. This method prevents ordering the wrong revision.

Stop wasting time on mismatched part numbers. This factory catalog gives you the exact data a CASE dealer uses. Access the Factory Manual now and keep your CX40B running with the right components.
