Case WX145 Parts Catalog – What You Need to Order Correct Parts

If you’ve ever ordered a hydraulic filter for a Case WX145 and gotten the wrong one because you guessed the serial number range, you know the frustration. That’s exactly why this Parts Catalog exists. Not a service manual – a parts catalog. 597 pages of OEM part numbers, reference codes, and version lists so you stop wasting money on returns. I’ve been a tech for 28 years, and I’ve seen guys order three different cylinder seals because they didn’t have the version code. This book fixes that.

Filters and Maintenance Parts – Page 2 Breakdown

Right at the start, page 2 lists the maintenance parts section under “0 – FILTERS(00)”. You get part numbers like 8904039, 6915572, 6915571 with quantities and descriptions. If you’re servicing the hydraulic oil or fuel system on a WX145, you cross-reference those numbers against your machine’s serial number. Don’t assume one filter fits all – the version code matters.

Version Identification: Which WX145 Do You Have?

Page 4 shows the version table. Two variants: WX 145 WM (serial NSU0WX145, version code 01) and WX 145 WT (version code 02 with engine F4GE9484E*J600). The manual tells you exactly where to find the machine serial number and engine serial number. Write them down in the space provided on page 4. I’ve seen guys swap a WM hydraulic pump into a WT machine and blow seals because the part numbers are different. This page stops that.

3 Key Reasons to Use OEM Parts Listings

First, aftermarket catalogs often merge multiple model years. This is a genuine Case PDF, original factory print. Second, every part number ties to a specific version code – no guessing. Third, the exploded view diagrams (not shown in excerpt but present in full catalog) let you verify the shape and position of each component. Third-party databases sometimes substitute superseded numbers without marking them. Not here.

Does This Catalog Include Service Procedures?

No. This is a parts catalog, not a repair manual. If you need torque specs for the swing gearbox or hydraulic pump removal steps, you want the Case WX145 WX165 WX185 Service Manual – Section: Section 8 or the Case WX145 Wheel Excavator Parts Catalogue for the full parts breakdown. For undercarriage hydraulic components on a similar machine, check Case CX160B 2007 Parts Catalog – OEM Undercarriage Hydraulics. But for ordering the right bolt, seal, or filter cartridge – this catalog is the authority.

How to Use the Version Code System

Flip to page 4. Find your machine’s model code (WM or WT). Match the version code (01 or 02). Then look up the part number in the corresponding section. The catalog uses a numbering system that groups parts by function: 0 for filters, 0 for version identification, then later sections for engine, hydraulics, etc. If you don’t know your version code, stop and find it. The catalog gives you the locations.

Page Count and Document Authenticity

This is a full 597 pages, scanned from the OEM Case publication. No reprints, no copy-paste from third-party aggregators. The PDF is layer-searchable. You get the same tables a dealer parts counter uses. For background on why OEM documents matter, see the Automotive Industry Overview. Another read on that topic: Automotive Industry Overview.

FAQ – Common Questions About This Catalog

Will this catalog help me repair a hydraulic leak?

No. It lists the seals and O-rings you need, but not how to install them. For that, get the service manual.

How do I find the right part number for my machine’s version?

Locate the version code (01 or 02) on page 4 using your serial number. Then cross-reference that code in the part tables. Each table includes the version column. If you skip this step, you risk ordering parts for the wrong variant.

Does this cover Tier 2 machines?

This catalog is for Tier 3 WX145 models built from 6/07 onward. Earlier Tier 2 machines use different filter part numbers and some different hydraulic components. The version list on page 4 only shows Tier 3 engine codes.

Can I print pages from the PDF?

Yes. The PDF is not locked. Print the version page and the filter section for your machine. Keep them in the cab.
