Case WX240 Parts Catalog – Factory OEM Parts Breakdown

You’ve got a WX240 wheeled excavator down in the yard. The lower carriage seal blew, and you need the exact part number for that track adjuster assembly. You flip through three different aftermarket websites, get a number that looks right, order it – and it’s the wrong revision. That’s why you need the real thing. Case’s factory Case WX240 Parts Catalog runs 568 pages of nothing but OEM part numbers, figure callouts, and serial-number-specific breakdowns. No guessing.

Lower Carriage and Upper Carriage Exploded Views

The catalog breaks the machine into two major main groups: lower carriage (page 2) and upper carriage (page 4). Each figure references a dedicated page with exploded diagrams and a table listing part number, quantity, and description. Need the drive motor seal? Look up figure 36.005/001 under upper carriage – the catalog tells you exactly which figure to flip to. That cross-reference system saves you from ordering a $200 seal kit that doesn’t fit the S/N 303501-UP range.

Part Number Format and Serial Number Breaks

Every assembly is tied to a specific serial number break. The lower carriage section starts with S/N 303501-UP. That means older machines before that break use different part numbers – and the catalog shows both. You see a reference like “NS 1 SEE FIGURE 01.200/002” – that’s a non-serviceable item, so you order the entire subassembly. Experienced mechanics know not to chase individual components that aren’t sold separately. Save yourself the phone call with your dealer.

Who Actually Uses This Catalog?

This isn’t a service manual – it’s a parts reference. If you’re a fleet mechanic rebuilding a WX240 after a hard season, or an owner-operator sourcing your own replacement parts, you need the factory part numbers. DIYers who maintain their own equipment will find the exploded views essential for disassembly order. I’ve seen people order the wrong hydraulic hose by measuring the length – only to find the banjo fitting angle is wrong. The catalog eliminates that because each hose is listed by part number with the correct fitting orientation. Pair it with Case WX210 WX240 Hydraulic Excavator Service Manual – Section: Sect. 7 for the torque specs on the swivel joint.

OEM Documentation vs. Aftermarket Lists

Aftermarket parts catalogs often combine multiple model years into one generic list. The Case factory catalog uses separate figure numbers for each revision. Look at the upper carriage listing: figure 92.020/001 is the operator cab structure, while figure 11.012/001 covers the engine mounting. Aftermarket PDFs might label them “Cab” and “Engine” without figure cross-references – then you realise the part you need is actually under figure 32.150/001 (air conditioning system). You waste hours. OEM documentation solves that because the figure numbers are the same ones your dealer uses. They don’t guess. For a broader look at how these machines fit into the Automotive Industry Overview, keep in mind the same rigorous engineering standards apply.

3 Reasons to Stick With Factory Parts Data

First, the part numbers are checked against current production – if Case superseded a number, the catalog notes it. Second, the illustrations are drawn from the actual CAD models, not a redrawn line art that omits washers and O-rings. Third, you get the same data the Case dealer parts counter uses. You can call them with a figure and reference and they’ll know exactly what you need. That saves you the markup they charge for hunting it down for you. If you need the operator’s perspective, check Case WX210, WX240 2005 Operators Manual – Factory OEM and Case WX210, WX240 2005 Operators Manual – Factory Specs.

One more thing: the catalog uses “NS” (non-serviceable) indicators on some items. Don’t try to rebuild a sealed cylinder – you’ll just contaminate the hydraulic system. Order the complete assembly. That page 2 lower carriage listing shows four major references: lower frame, travel motor, front axle, and stabiliser legs. Each of those sub-figures has its own part number table. That’s 568 pages of precise data.

FAQ

Does the Case WX240 Parts Catalog include torque specifications?

No. This is a parts catalog, not a service manual. Torque values are in the factory service manual, which is a separate document.

How do I find the part number for the hydraulic pump on a WX240 with S/N 303501-UP?

Turn to page 4 – upper carriage section. Look for figure 13.010/001 (hydraulic pump assembly) in the table. That figure shows the exploded view with each pump component (gear pump, piston pump, charge pump) listed individually. The part numbers are specific to the S/N break. If the serial number isn’t in that range, you need the earlier figure for pre-303501 machines. The catalog covers both. That’s why you need to verify your machine’s serial before ordering. I’ve seen a $1,200 pump come in with the wrong mounting flange because someone skipped that step. Don’t be that guy.
