Case CX240B Parts Catalog – Factory OEM Part Numbers and Exploded Views

If you are ordering parts for a CX240B, you need the exact part number. Aftermarket catalogs might get you close, but close means a cylinder that doesn’t seal or a bearing that’s 0.005″ off. I’ve seen it. This is the genuine Case Parts Catalog – 467 pages, direct from the factory. It covers every system on the CX240B crawler excavator, both LC and NLC undercarriage variants. You want the right seal kit for the boom cylinder? You find the figure reference, match the part number, order it. Done.

Let me walk through what is actually in here so you understand why this catalog belongs on your bench, not buried in a drawer.

Engine and Hydraulic Systems: Where This Catalog Saves You Time

The TOC starts with the component index – 35 major groups. Section 16 covers the engine mounting and oil circuit, figures 02-001-00 01 through 02-286-01 01. Section 13 is the hydraulic reservoir and system, figures 08-001-00 01 to 08-067-00 01. If you need a hydraulic pump, turn to section 14. Each figure is an exploded view with callouts and part numbers. You don’t guess. You look up the figure number referenced in the index. That’s it.

What’s Inside the 467-Page Catalog?

Thirty-five numbered sections, each with its own set of figures. Bucket, bucket cylinder, dipper, dipper cylinder, monoblock boom, boom cylinder – all with their own figure sets. Section 5 covers the undercarriage and hydraulic circuit, but note there are two separate listings: one for CX240B LC and one for CX240B NLC. That matters. Track frame parts, rollers, idlers, sprockets – they differ between the long and normal track frames. Section 24 deals with travel motor and reduction gear. Every fastener, every seal, every bushing is there.

Undercarriage Breakdown: LC vs NLC Variants

Look at section 21: “UNDERCARRIAGE, HYDRAULIC CIRCUIT For CX240B LC” and the same for NLC. These are not interchangeable. If you order a chain guide for the LC and install it on an NLC, the track alignment will be off. The catalog shows separate figure numbers – 05-001-00 01 vs 05-001-01 01. That level of detail is what keeps a job from turning into a two-day headache. Cross-reference the serial number of your machine to confirm which variant you have, then pull the parts from the correct figure.

3 Reasons You Need Factory Part Numbers

First, supersession history. Case updates part numbers. Aftermarket catalogs often list old numbers. This catalog shows the current number as of the printing date. Second, exploded views show exactly how parts fit together. You see the orientation of seals, the order of washers. Third, when you call a dealer, you give them the exact number and they don’t ask “Are you sure?” – they order it. Saves hours on the phone.

Cylinder Identification: Bucket, Boom, Dipper

Three separate cylinder sections. Bucket cylinder – section 3, figures 08-021-00 01 and 08-303-00 01. Dipper cylinder – section 5, figures 08-017-00 01, 08-018-00 01, 08-302-00 1, and 08-302-01 01. Boom cylinder – section 7, figures 08-013-00 01 through 08-015-00 01, plus 08-300-00 01 through 08-301-01 01. Each figure lists every internal component: piston, rod, seals, bushings. If you are rebuilding a cylinder, this catalog gives you the seal kit part number. Pair it with the service manual for torque specs, but the catalog gets you the parts.

Electrical system is covered in section 19 – batteries, wiring harnesses, alternator, starter. Air conditioning in section 34. Operator’s compartment, cab, seat, control levers – sections 31 through 33. Even the side instrument panel – section 35. Everything is broken down into figures.

Case CX160B CX210B CX240B CX290B AC Troubleshooting Manual if the AC is acting up. Case CX Series Electrics Layout Diagram Training Manual for wiring schematics. These complement the parts catalog – the catalog gives you the part numbers, the service manual tells you how to install them.

Is this the same as a service manual?

No. This is a parts catalog for part numbers and exploded views only.

Can I use this to rebuild the hydraulic pump?

Yes, for identifying parts. It lists every component in the pump assembly – gears, bearings, seal kit – with figure references. You will see the exploded view and callouts. However, it does not contain disassembly procedures or torque specs. You need the separate service manual for that. I recommend ordering both: the parts catalog to get the correct seal kit and the service manual to know how tight to torque the end cover. Without both, you risk a leak on a $3,000 pump rebuild.

Bottom line: 467 pages of factory-correct part numbers, organized by system, with cross-referenced figure numbers. No aftermarket guesswork. If you are working on a Case CX240B, get the right parts the first time. Access the Factory Manual from AutoRepairManuals today and keep it within arm’s reach of your toolbox.
