Case WX145 Parts Catalog – 1015 Pages of OEM Part Numbers and Exploded Diagrams

You order parts for a Case WX145 Parts Catalog job, and when the box shows up, the bracket doesn’t fit, the seal is the wrong diameter, and the hydraulic line hits the frame. That’s the cost of guessing. I’ve seen that cost run into four figures on a single machine, plus lost rental time. A Parts Catalog is your insurance against that – if you use it right.

This is the factory Case WX145 Parts Catalog, printed from the original OEM files. 1015 pages of part numbers, reference numbers, quantity breakdowns, and exploded diagram callouts. Not a reprint of a third-party scan, not a generic illustration book. This is what the Case dealer pulls up when you call. I’ve used these catalogs in my shop for years; they save you from the “that looks about right” moment that costs you a week of downtime.

1,015 Pages – What’s Inside the Parts Catalog

Every section of the WX145 wheel excavator is broken out by assembly group. For example, the Lower Carriage Excavator section (00.200) starts on page 2 and gives you the main frame assembly with mount parts, including reference numbers to sub-figures like 01.200/2988268000. You get the part number, description, and quantity per assembly. Need a catseye reflector? Part 2900948, quantity 2. Frame support? See figure 04.012/2987492002. That level of detail repeats for every system on the machine.

Frame Lower Carriage with Mount: A Closer Look

The catalog splits lower carriage variants by serial numbers. Page 3 shows the WX145 (from 5/04-) with frame part 2992642 and references to two different frame assemblies depending on the suffix. This matters because a 2005 machine may have a different lower carriage than a 2008. The catalog flags those differences so you order the correct weldment, not a close match. If you skip that check, you’re buying a $2,000 part that doesn’t fit.

How to Cross-Reference Part Numbers

Each assembly figure has a table with Ref, Part Number, Qty, and Description. The column format is consistent across all 1015 pages. You find the part, write down the number, call your supplier or check it against your service manual. If you already have the Case WX145 WX165 WX185 Service Manual – Section: Section 8, you can match the part numbers to the torque specs and repair procedures. That combination – a parts catalog and a service manual – is the only way to do it right.

Why OEM Parts Catalogs Beat Aftermarket Lookups

I’ve had it up to here with aftermarket sites that throw a blurry diagram and a list of “compatible” part numbers. They don’t tell you the serial number split, they don’t guarantee the revision level, and they’ll sell you a generic seal that fails after ten hours. This catalog is Case factory data, verified against the production date and machine series. The part number you get here is the part that came on the machine from the factory. You can look up parts for the Case WX145 Tier 3 Wheeled Excavator Parts Catalogue or cross-reference with other models like the Case CX160B 2007 Parts Catalog – OEM Undercarriage Hydraulics. The format and numbering scheme are consistent across the Case lineup.

3 Reasons a Parts Catalog Belongs in Your Toolbox

One: You stop wasting time on wrong orders. Two: You know exactly which fasteners, seals, and brackets go where. Three: You can plan your rebuild ahead of time instead of tearing down and then discovering you need a part that’s on backorder. The industrial equipment world runs on part numbers; if you don’t have the right one, you’re in the dark. This catalog puts the light on for you.

Frequently Asked Questions

Does this parts catalog include torque specifications?

No, this is a parts catalog. Torque specs are in the service manual. Get both.

Can I use this to order parts for a 2005 WX145?

Yes, the catalog covers machines from 5/04 production with parts grouping references. Pay attention to the serial number suffixes in figures like 00.200/2988620000 versus 00.200/2990469000 to get the correct revision.

Are the diagrams clear enough to identify small components?

Diagrams are scanned from OEM originals at high resolution. Each component is referenced with a callout number that matches the part table. You can identify seals, pins, bushings, and hardware down to the washer.

How does this differ from the service manual?

The service manual gives you removal, installation, and diagnostic procedures with torque values and tolerances. The parts catalog gives you the part numbers and assembly breakdowns but no repair steps. You need the service manual for the “how,” and the parts catalog for the “what.” Together they form the complete factory documentation set for the WX145. That’s why I keep both on the workbench.

If you work on these machines, you know the difference between a job that flows and one that turns into a parts chase. The Case WX145 Parts Catalog stops the chase before it starts. Access the Factory Manual now and put the right part numbers in your hands.
