Case 580CK Series B 1979 Parts Catalog

You’ve got a Case 580CK Series B 1979 Parts Catalog in your hands – or you should. If you’ve ever stood at a parts counter guessing which dipper cylinder seal kit fits a 4” bore with a 35-1/8” stroke, you know the pain of aftermarket cross-reference lists that don’t match. This catalog ends that. Straight OEM part numbers, exploded views, and quantities. No reprints, no guesswork.

The dipper cylinder assembly (G32079) is the heart of the backhoe, and page 1 gives you every piece: tube assembly (G32831), gland assembly (G33190), the split piston halves (G33159 and D46930), and the V-type packing set (D47204). The seal kit asterisk (*) items are all listed – order G34594 and you’ve got the complete set. That’s the kind of detail that keeps a machine digging instead of sitting.

580CK Series B Cylinder Breakdown

The catalog splits the dipper cylinder into two configurations: two-piece piston design for the G32079 (page 1) and the G101175 (page 5). Part numbers are specific to each. The gland assembly G33190 has an identification ring – note that. If you’re rebuilding, you need the correct gland O-ring (A27507), backup ring (G32175), and piston rod seal (D36971) or the severe-duty option (G100778) for extreme heat or cold. These aren’t generic dimensions – they’re Case factory numbers with exact thread specs and grade 8 hardware (hex bolt 28-2040, 1-1/4”-12 NF x 2-1/2”).

Why the 1979 Parts Catalog Beats Aftermarket Parts Lists

Third-party catalogs often lump multiple years or models together, leaving you with a part that almost fits. This 100-page book is year-specific: April 1979, printed in U.S.A. Every bushing, washer, wiper, and grease fitting has its own part number. The dipper cylinder rod assembly (G33154) is 2” diameter – if you grab a rod from a later model, the bushing bore changes. You won’t catch that in a generic cross-reference. Case 580CK Series B & Model 35 Loader Backhoe Parts Catalog covers the entire loader and backhoe grouping (section 35), not just the cylinder.

7 Systems Covered in 100 Pages

The catalog doesn’t stop at the dipper. It breaks down the loader bucket, backhoe swing frame, stabilizer legs, and hydraulic lines. Each subsystem gets its own exploded diagram with part numbers and required quantities. For the backhoe dipper cylinder alone, you get the tube, gland, piston, rod, bushings, wiper, seal, and both grease fittings (90-degree Q-55 and straight 219-1). That’s 20 line items on one page. Multiply that across the entire machine – loader arms, bucket cylinders, control valves – and you’ve got a complete reference for ordering anything from a bushing to a full cylinder assembly.

Using the Dipper Cylinder Parts List

Page 1 is your go-to for the G32079 assembly. The illustration shows the cross-section of the cylinder with callouts for each reference number. The seal kit (G34594) replaces all asterisk items – wiper, piston rod seal, backup ring, gland O-ring, and V-packing set. If you’re rebuilding, order the kit and the two split piston halves separately unless the piston is scored. The bolt (28-2040) is a 1-1/4”-12 NF grade 8 – torque it to the factory spec printed in the repair manual, not to “feel tight.”

Source Validity: Factory OEM vs Third-Party Reprints

This isn’t a scanned copy of a scanned copy. AutoRepairManuals holds the original OEM publication from 1979. The part numbers match Case’s own system – no substituted aftermarket equivalents. The dipper cylinder tube assembly G32831 is listed as quantity 2 on page 1; a reprint might drop that detail. For anyone who has been burned by a misprinted part number on a shady PDF, this is the difference between a correct rebuild and a return trip to the parts counter. Case 580CK Series B Tractor Parts Catalog F1179 and Case 580CK Series B, 35 Loader, 35 Backhoe 1979 Parts Catalog cover related models if your machine is a variant.

Who Needs This Catalog

Home garage mechanics pulling a backhoe off a 580CK – you need the dipper cylinder seal kit part number. Shop owners who bill by the hour – you need to know the correct bushing (D33047) before you tear down. Even a beginner can follow the diagrams: each part is labeled with a reference number that ties directly to the table. There’s no interpretation required. If you’ve ever spent an afternoon hunting down a greasable bushing because the parts store gave you the wrong one, this catalog stops that.

Most of the backhoe cylinder components – the gland, the piston rod wiper, the V-packing – are wear items. Order the seal kit (G34594) once, and you’ll have everything for a full rebuild. The catalog even lists the severe-hot-climate seal as a service option; if you’re in Texas like me, that’s the one you want.

A note on the Automotive Industry Overview – heavy equipment follows the same principles of cylindrical component rebuild. The Automotive Industry Overview covers the broader context, but for the Case 580CK, you need the factory parts list.

FAQ

Does the catalog include the loader bucket cylinders?

Yes. Section 35 covers the entire loader and backhoe. The dipper cylinder is the most detailed, but the bucket and boom cylinders are in separate subsections with their own part numbers and seal kits.

What page has the dipper cylinder seal kit number?

Page 1. The seal kit G34594 is listed at the bottom of the table, replacing all asterisk items.

If your backhoe dipper cylinder leaks after a rebuild, it’s because the gland O-ring or wiper wasn’t replaced. That’s on you if you didn’t use the factory parts list. Access the factory manual – the 1979 Case 580CK Series B Parts Catalog – and get the right parts the first time.
