Case 310, 310C Parts Catalog – Factory Parts Breakdown for Crawler Tractors

Street-level parts catalogs from third-party reprint houses waste your time. You get blurry diagrams, mismatched part numbers, and no clue which cylinder seal kit fits a 310C boom. That’s why I only use factory copies when I’m rebuilding a Case backhoe. The Case 310, 310C Parts Catalog you’re looking at is an authentic OEM document—60 pages of exploded-view illustrations and genuine Case part numbers, not some scanned mess.

Hydraulic Cylinder Breakdowns – Boom, Bucket, Crowd, and Swing

Five different cylinder types live inside this catalog. The boom Cylinder covers pages 8, 46, and 48. The bucket cylinder hits pages 10 and 52. Crowd cylinder shares pages 10 and 50. Swing and stabilizer cylinders have dedicated spreads on pages 6, 42, and 44. If you need to rebuild any hydraulic component on a 310 or 310C, this index tells you exactly which assembly drawing to pull up. No flipping randomly through sixty pages.

Hose and Fitting Conversion Table: Cutting to the Correct Length

The OCR excerpt shows a table that converts original equipment assembly numbers into bulk hose numbers, cut lengths in inches, and fitting part numbers. For example, assembly number 35194 uses hose A21573 cut to 66 inches with two A220-205 fittings. Another line shows 35214 uses A21572 cut to 14-7/8 inches with a A220-203 and a A220-223. If you’ve ever fought a pre-made hose that’s two inches too long, this table alone justifies the access.

That table is the reason you buy this catalog.

Case 310, 310C Parts Catalog – What the Alphabetical Index Covers

The alphabetical index (page 3) lists every major group: Boom, Buckets, Cylinders, Dipper Arm, Hydraulics, Levers, Mounting Parts, Pump, Stabilizers, Swing Linkage, Tower, Transfers, Valves. The numerical index on page 54 cross-references every part number back to its page. This structure is identical to what Case dealers used when these machines were new. If you’re buying a Case 310 Crawler Operator’s Manual or a Case 26 Backhoe Operators Manual, this parts catalog completes the set.

Why OEM Documentation Beats Aftermarket Reprints

Aftermarket catalogs often re-photograph copies, lose resolution on part numbers, and omit the conversion table. This is a clean factory file. Every part number came from Case’s own parts system. The hose table alone—with its fractional-inch cut lengths—is something a reprint house would skip. If you need a Case 310, 310B Parts Catalog – OEM Factory Parts Breakdown for a slightly older model, that document exists too. But for the 310C, this is the exact spec. The Automotive Industry Overview has standardized part numbering conventions, but Case’s own system is the only one that guarantees fit.

Who Needs This 60-Page Parts Catalog?

Farmers maintaining their own crawler loader. Equipment dealers cross-referencing NOS parts. Wrench owners who want to order seals without pulling the cylinder first. If you work on Case 310 or 310C machines, this catalog eliminates the back-and-forth with parts counters. The index lists every valve, every pump, every cylinder group.

Does this catalog cover the engine or just the backhoe attachment?

This is strictly a parts catalog for the backhoe attachment and related hydraulic systems. Power train and engine parts are not included. For engine specs, you need the separate service manual.

Can I use this catalog to order replacement hydraulic cylinders?

Yes. Each cylinder — boom, bucket, crowd, stabilizer, and swing — has its own section with individual part numbers. The Boom cylinder appears on pages 8, 46, and 48. Use the index to find the exact assembly.

Are there torque specs in this catalog?

No. This is a parts catalog, not a service manual. It lists part numbers and assembly breakdowns only. You need the factory service manual for torque values.

How do I use the hose conversion table?

Find your original equipment assembly number in the left column. The table gives you bulk hose number, cut length in inches, and two fitting numbers. That lets you build a replacement line without buying a pre-made assembly. For example, assembly number 19178 uses hose A21573 cut to 30 inches with two A220-205 fittings.

You’ve got two options: keep guessing which seal fits your boom cylinder, or grab this OEM catalog and look it up. I’ve rebuilt more Case backhoes than I can count, and I wouldn’t touch a 310C without this document on the bench next to the parts washer. Automotive Industry Overview covers the big picture, but for a specific 310 or 310C, the factory parts catalog is what you actually need.
