Case 32, W-7, W-9A, W-9B, W-10 Parts Catalog

You get handed a parts catalog that was scanned from a third‑generation copy, the part numbers are blurred, and the illustration shows the wrong cylinder. Then you order a seal kit that doesn’t fit, and the machine sits another day. That’s why you need this Case 32, W-7, W-9A, W-9B, W-10 Parts Catalog — the original OEM print. 58 pages, no reprints, no guesswork. It covers every hydraulic line, stabilizer cylinder, and boom assembly with the part numbers that Case stamped on the original drawing.

Boom, Buckets, and Dipper Arm Coverage

The backhoe boom assembly is on page 9. The bucket section starts on page 13. If you’re rebuilding the dipper arm, that’s also on page 9. You get exploded views with callouts that match the factory parts numbering. No aftermarket “similar to” nonsense. The bucket listing includes the part numbers for the cutting edge and the weld‑on ears. I’ve seen guys order the wrong bucket cylinder because they used a generic cross‑reference. This catalog kills that problem.

Which Hydraulic Cylinder Sections Are Included?

Four separate cylinder groups are broken out: Cylinder – Backhoe Boom (pages 9,37,43), Cylinder – Backhoe Bucket (9,39,45), Cylinder – Backhoe Crowd (9,37,43), and Cylinders – Backhoe Stabilizer (5,41). The swing cylinders are in the stabilizer section on page 5 and page 41. Each group shows the rod, piston, packing, and retainer part numbers. If you need the seal kit for a W‑10 crowd cylinder, you find it here without calling the dealer and hoping the counter guy gets it right.

58 Pages of Verified Part Numbers

This is a 58‑page OEM document, not a compressed PDF that loses detail. The hydraulic coupling and diversion valve sections span pages 17, 19, 23, 27. The diverter valve also appears in the W‑7 basic backhoe hydraulics on page 17, and again in the W‑9B hydraulics on pages 23–25. That tells you the valve configurations differ between loader models. Ignore that and you install the wrong diverter and lose your swing circuit. The catalog also includes a Hose and Fitting Conversion Part Number table on page 46 — critical when you’re adapting old JIC fittings to newer O‑ring face seals.

Check the Numerical Index Before Ordering

The Numerical Index on page 47 lists every part number in alphabetical‑numerical order. You find the number, then flip to the page. Example: if you need the counterweight mounting parts (page 15) but the counterweight is only used with the backhoe removed, the index tells you that. Saves you from ordering a bracket that won’t clear the loader frame. Use the index. I’ve seen techs skip it and end up with a box of wrong bushings.

Cylinder Breakdown: Boom, Crowd, Stabilizer, Swing

The hydraulics section splits the cylinders by function. For the W‑9A and W‑10, the boom, crowd, and bucket cylinders are grouped together on pages 37 and 39. Swing and stabilizer cylinders are on page 35. The decal kit on page 45 includes the control pattern labels. If you swap the boom and crowd hoses because the decals are missing, you lose digging force. The catalog gives you the exact decal part number to restore factory markings. Match it to your loader’s serial number range if possible — the W‑7 and W‑9B may use different valve stacks. This catalog covers all four loader models (W‑7, W‑9A, W‑9B, W‑10) and the Model 32 backhoe itself.

Case Model 32 Backhoe Parts Catalog is the same document — different SKU for multiple copies. If you need the full safety and spec document for the loader, get the Case 32, 530 CK 1996 Operators Manual – Factory Safety & Specs.

Does this catalog include torque specs for the cylinder gland nuts?

No, this is a parts catalog — it lists part numbers, not assembly torques. You need the service manual for torque values.

How do I find the correct part number for a W‑9B stabilizer cylinder?

Start in the Alphabetical Index under “Cylinders – Backhoe Stabilizer” which points to pages 5 and 41. Page 5 shows the mounting parts and the cylinder assembly. Page 41 gives the exploded view with individual components. Cross‑reference the loader serial number plate to the model year information in the front matter (not included in this scan). If the stabilizer cylinder uses a different port orientation than shown, call Case with the cylinder casting number — don’t order by the loader model alone. The W‑9B and W‑10 share some stabilizer parts but the hose routing differs; the catalog’s hydraulic section on page 23 (Basic Backhoe W‑9B) shows the correct tube and hose assemblies.

When you rebuild a backhoe, guessing the part number costs you a day and a return shipping label. This catalog gives you the factory drawing and the number that Case assigned. Access the Factory Manual and keep it with the machine. Your parts counter guy will thank you.
