Case 440, 430, 21, 210B Parts Catalog

I've been wrenching on Case equipment long enough to know the difference between a parts catalog that came off a factory printer and something a third-party outfit slapped together from blurry scans. This Case 440, 430, 21, 210B Parts Catalog is the real deal – 78 pages of OEM part numbers, indexed the way Case intended. If you've ever ordered the wrong hydraulic cylinder because an aftermarket parts site gave you a “compatible” number that didn't fit, you know the pain this thing fixes.

What the Parts Catalog Actually Contains

Open the alphabetical index and you see exactly what you need: Boom on page 9, Dipper Arm on page 11, Tower on page 7. The structure is dead simple – find the assembly, get the factory part number. No guesswork. No cross-referencing to a third-party database that may or may not be up to date. Need a replacement Cylinder – Boom, Hydraulic? Pages 41-42. Cylinder – Bucket, Hydraulic? Pages 47-48. Every cylinder used on the model 21 backhoe is listed with its original Case code.

78 Pages of Factory-Coded Parts

The backhoe serial numbers are spelled out in the first few pages: Model 21 backhoe for 210B wheel tractor (serial 4023382 to 4041266) and for 430 and 440 wheel tractors (serial 4041266 to 4058655). That tells you exactly which machines this catalog covers. If your machine falls outside that range, cross-check the serial numbers first. These 78 pages are not a generic “fits all” – they're specific to production runs Case designated.

Boom, Dipper Arm, and Tower: The Backbone Sections

Any backhoe repair starts with those three assemblies. The catalog dedicates separate pages to each – Boom (page 9), Dipper Arm (page 11), Tower (page 7). You also get the full hydraulic breakdown: Hydraulics – Backhoe, Basic (page 25), Pump Drive (page 25), Hydraulics – Swing and Stabilizer Cylinders (page 33), Hydraulics – Boom, Crowd, and Bucket Cylinders (pages 27-31). If you're rebuilding a swing cylinder, you want the swing cylinder section (pages 35-36). Don't rely on aftermarket parts lists that lump everything under “hydraulics.”

How to Use This for a Cylinder Rebuild

Say you have a leaking stabilizer cylinder on a 430 tractor. Flip to page 37 or 39 – Cylinders – Stabilizer, Hydraulic. The exploded view shows every seal, piston, rod, and gland nut with a part number. Order exactly what Case spec'd. No wondering if a generic seal kit will hold pressure. The same logic applies to control valves (pages 51-59), the hydraulic pump (pages 61-63), and the cross-over relief valve (page 65). Use the numerical index on page 69 to look up a part number if you already have one – the cross-reference goes back to the assembly page.

Aftermarket Catalogs vs. This OEM Document

I've seen cheap reprints where the part numbers are blurred out or missing. This is a direct scan of the original Case Parts Catalog No. B662. No reprint house has altered the data. Every digit is legible. The mounting parts, weight boxes, decals – all included. If you're restoring a 210B or maintaining a fleet of 440s, you need the factory catalog. The CASE 440 440CT 2006 Parts Catalog covers a different series; this one specifically addresses the model 21 backhoe attachment. Pair it with the CASE 430 440 440CT Repair Manual for service procedures, and grab the Case 430 Wheel Fork Lift Operators Manual 2001 if you run a forklift attachment.

Does this catalog include part numbers for all four models?

Yes. It covers the Case model 21 backhoe when mounted on the 210B, 430, and 440 wheel tractors. The serial number ranges are printed inside.

Can I use this for a 430 tractor with a different backhoe serial number?

Only if your backhoe serial number falls between 4041266 and 4058655. Outside that range, some part numbers may differ – especially for cylinders and control valves. Check your machine's serial plate.

Why are there separate sections for boom cylinder and bucket cylinder?

Because they are different assemblies. The boom cylinder (pages 41-42) has a longer stroke and different port sizes than the bucket cylinder (pages 47-48). Ordering the wrong one means the pins won't align or the hydraulic hoses won't reach. The catalog eliminates that mistake.

What kind of diagrams are inside?

Exploded-view line drawings with each part called out to a reference number. The part number is listed in a table next to the diagram. No photos, but the drawings are clear enough to identify each seal, O-ring, and bolt.

You'll waste less time hunting down the right part if you work from this catalog. Whether you're rebuilding a swing cylinder on a 430 or sourcing a new hydraulic filter (page 64), having the OEM index in front of you saves phone calls and return trips to the parts counter. The Automotive Industry Overview won't help you here – only factory data will. Access the Factory Manual and keep it on your tablet or print a hard copy for the toolbox. Your next backhoe job will go smoother.
