Case CX20B, CX22B 2007 Parts Catalog

If you’re ordering parts for a CX20B or CX22B mini excavator and you don’t have the factory parts catalog, you’re gambling. I’ve seen mechanics pull a hydraulic line off, measure it with a tape, and order by guess – then wait three days for the wrong fitting. That’s billable hours down the drain. The Case CX20B, CX22B 2007 Parts Catalog puts 684 pages of OEM documentation in your hands. This isn’t a reprint or a third-party compilation. It’s direct from Case, with exploded diagrams and part numbers that match the assembly line.

This catalog covers both the CX20B and CX22B models. You get the same information a Case dealer uses: ordering rules, conversion charts, and the full number index. If you’ve ever tried to cross-reference a part number from an aftermarket site and ended up with a metric bolt where you needed an imperial one, you already understand why this document matters.

Parts Ordering Rules and Abbreviations

Page 4 lays out the ordering rules straight from Case. You want to know what information they need before they ship? It’s right there: model, serial number, part number, quantity. The abbreviation list on page 22 decodes every acronym Case prints on their drawings. No guessing what “CY” or “HYD” means – it’s spelled out.

I’ve watched guys order a “seal kit” without the revision letter and get the wrong thickness. The manual calls out which version applies to which serial range. If you skip that step, you own the wrong part.

Does This Manual Include Maintenance Parts?

Yes. Pages 29-31 cover maintenance parts: filters, belts, fluid specs for routine service. These are the items you’ll replace most often – air filters, fuel filters, hydraulic return filters. The catalog gives you the Case part number so you can cross it to aftermarket if you want, but at least you know the factory spec. No more asking the parts counter “is this the right one?” when the box says “fits Case excavators.”

684 Pages of OEM Documentation

That’s not fluff. The thickness comes from four languages (English, French, German, Italian) and complete exploded views for every assembly: undercarriage, swing gear, control valve, engine mounting. The identification and version list on pages 25-27 tells you which serial numbers correspond to which build changes. If your CX22B has a mid-life update, the catalog shows you the affected parts.

I run a six-bay shop. When a customer brings in a 2007 CX20B with a cracked manifold, I pull page 33 – the number index. Look up the part number, flip back to the exploded view, and verify. Twenty minutes, not three days.

Use the Number Index to Find Any Part

Page 33 is the numerical index. Every part number listed in the catalog appears here, cross-referenced to the figure and item number. If you have a part in your hand and don’t know where it goes, this is your map. You don’t need to flip through all 684 pages hunting. The index tells you exactly which assembly it belongs to.

Conversion Chart: Inch to Millimeter Specs

Page 23 has the conversion chart – inches to millimeters. Case uses both systems depending on the component. Thread pitches, seal diameters, hose lengths. Don’t assume. If the drawing calls out a 0.625” shaft, the chart gives you 15.875 mm. One less chance to order the wrong bearing.

Why OEM Documentation Beats Aftermarket Parts Catalogs

Aftermarket parts catalogs often group multiple models together and assume commonality. Case doesn’t. This document is specific to the CX20B and CX22B for the 2007 model year. Every part number has been verified against the factory bill of materials. I’ve had two aftermarket catalogs give me different numbers for the same track roller. The OEM catalog settled it in ten seconds.

If you need a repair manual instead of a parts catalog, check the CASE CX20B/CX22B/CX27B Hydraulic Excavator Repair Manual for service procedures and torque specs. For other Case models, browse the Case CX160B 2007 Parts Catalog – OEM Undercarriage Hydraulics and the CASE CX27B Mini-Excavators Parts Catalog 6th Edition.

Frequently Asked Questions

Can I use this parts catalog for repair procedures or torque specs?

No. This is a parts catalog – it shows exploded views and part numbers, not step-by-step removal or tightening sequences. That’s what the service manual is for.

How do I determine which version of the CX20B or CX22B I have?

Look at the identification and version list on pages 25-27 of the catalog. You’ll need your machine’s serial number. The list tells you the production range and any mid-life updates. If your serial number falls between two ranges, you may have a mix – order based on the specific component revision shown in the exploded view. Always verify the part number against the index before ordering; a single digit change can mean a different thread pitch or seal diameter. The catalog also includes notes on superseded parts, so check the number index on page 33 for any alternates.

Every time I hand a tech this catalog, the first thing they do is dog-ear page 33. That’s fine – it’s a work tool, not a library book. Access the Factory Manual and keep it on your tablet or print the sections you need. Your parts counter will thank you.
