Case CX225SR Parts Catalog – Factory Parts Breakdown

I’ve been an ASE Master Technician for 28 years, and I’ve seen more misordered parts than I’ve had hot meals in San Antonio. Guys grab a parts catalog from some third-party site, get the wrong spacer, and then the machine sits for a week. This Case CX225SR Parts Catalog is the real deal – 584 pages of factory-original exploded views and part numbers printed directly from Case’s own schematics. No aftermarket rehash, no guesswork.

The engine mounting section alone – page 2 of the PDF – gives you every bolt, washer, rubber block, and support bracket with the exact Case part number. Need the M16 x 140 bolt? It’s 827-16140. The spacer that sits between the engine and the frame? That’s 167984A1. If you’re replacing an engine on a CX225SR, you use this catalog to cross-check every fastener before you call the parts counter. It’s the difference between a job that gets done Friday afternoon and one that drags into next week.

Case CX225SR Parts Catalog: Engine Mounting and Air Filtration Sections

The catalog is organized by system. Two sections I rely on: engine mounting (02-003-00) and air filtration (02-005-00). The engine mounting page shows the complete assembly with reference numbers tied to a part number table. You see the rubber blocks (KRH1225, KRH1226) and the six plates (KRH1256) that isolate vibration. The air filtration section gives you the full air cleaner assembly – body KRH1248, inner and outer filter elements (KRH0652, KRH1320), and the evacuation valve KRH1250. Each part has a quantity and a description that tells you exactly what it fits.

For the air cleaner cap – that’s 165437A1. If you lose it, you’re pulling dirt into the intake. That cap is not something you can fabricate from hardware-store parts. Use the catalog number, order from Case, and move on.

If you need the step-by-step procedure for removing that engine, you want the Case CX225SR 2006 Service Manual – Section: Introduction for torque specs and sequence. The parts catalog won’t tell you how tight to turn a bolt – it tells you which bolt to turn.

What Does the Parts Catalog Cover?

This catalog covers the entire CX225SR crawler excavator – from the engine mounting through the hydraulic pumps, swing gear, undercarriage, and electrical components. Every page is keyed to a system number. You get part numbers for seals, hoses, clamps, and fasteners. No fluid capacities, no diagnostic trees, no repair procedures. That’s not its job. Its job is to make sure the box that shows up from the dealer has the right contents.

I’ve had junior techs try to order a new hydraulic hose by measuring the old one with a tape. That works until the fittings are different angles. The catalog shows the hose assembly with the correct part number – no measuring required.

Using Part Numbers: Why Factory Data Matters

Aftermarket parts catalogs renumber things for their own inventory. You call a parts house, give them a number from a third-party list, and they hand you a box that says “comparable to OEM.” Comparable is not identical. This catalog uses Case factory numbers – KRH, KHH, 827-, etc. Those numbers cross-reference directly at any Case dealer. When you open the catalog and read “Ref Part Number Qty Description,” you’re looking at data that came from Case’s own engineering drawings.

The catalog also notes serial number cutoffs. For the engine assembly, you’ll see “Until DCH22U0157” and “DCH22U0158 And After.” The parts changed. If you ignore that cutoff, you’ll get the wrong block, wrong supports, and wrong rubber isolators. That’s a few hundred dollars and a week of downtime. The catalog spells it out – you just have to check your machine’s serial plate.

4 Common Mistakes When Ordering CX225SR Parts

Mistake one: ordering the air cleaner filter from a generic catalog. The CX225SR uses a dual-stage filter – KRH0652 for the outer, KRH1320 for the inner – and aftermarket filters often skip the inner element. Mistake two: ignoring hardware. The engine mounting uses 10.9-grade bolts and M10 locking washers. You can’t substitute Grade 8.8. Mistake three: assuming the clamp from an earlier model fits. The part numbers for the large hose clamps (150902A1) changed between production runs. Mistake four: ordering without verifying the serial number. The catalog lists multiple engine part numbers based on unit range. Get the VIN before you pick up the phone.

For daily operation and safe handling, the Case CX225SR Excavator Operator’s Manual 2002 gives you load charts and controls. That’s a different document – don’t confuse the two.

Check the Serial Number Cutoffs

Look at the entry for the engine: “2 KRH1493 1 ENGINE ASSY, , Until DCH22U0157” and “2 KRH1641 1 ENGINE, , DCH22U0158 And After.” If you have a machine built before that cutoff, you need KRH1493. After, KRH1641. The same applies to supports, brackets, and even step plates. The catalog gives you the reference pages – 02-013-00, 02-019-00, etc. – so you can cross-check before you buy.

The Case CX225SR 2004 Repair Manual – Factory Specs & Procedures includes the procedures that require those parts. Use the parts catalog to source, then the repair manual to install.

The industrial standards for construction equipment documentation are defined in the Automotive Industry Overview. That same source confirms why OEM documents like this are the gold standard for accuracy. Automotive Industry Overview also covers how manufacturers control revision levels – which explains why this catalog lists both KRH1493 and KRH1641.

FAQ – Case CX225SR Parts Catalog

Is this a service manual or a parts catalog?

Parts catalog only. No repair steps, no torque specs. It’s for ordering and identifying components.

Can I use this to rebuild my engine?

Not directly. It gives part numbers for every component (pistons, rings, bearings, seals), but lacks clearances, torque sequences, and assembly instructions. Pair it with the factory service manual for a full rebuild. You’ll need the part numbers from the catalog to purchase correct bearings and gaskets – mixing up a main bearing shell could cost you a crank.

Does this catalog include serial number breaks?

Yes. Every major assembly lists the serial number range it applies to. For example, the engine assembly has separate numbers for machines before and after DCH22U0157.

How do I order parts using this catalog?

Find the system section (e.g., 02-003-00 for engine mounting), locate the exploded diagram, note the reference number, then read the part number and description from the table. Give that number to your Case dealer. Always verify your machine’s serial number against any cutoff noted.

If you need to get the right parts the first time – every time – stop relying on aftermarket cross-reference charts. Access the Factory Manual directly from AutoRepairManuals and keep this catalog on your shop tablet or printed in a binder. It’s the only parts book for the CX225SR that matches Case’s own inventory system.
