Sperry New Holland 840 Parts Catalog – Factory Part Numbers and Exploded Views

If you’ve ever ordered a part for an old round baler and ended up with a bracket that doesn’t line up or a bolt that’s half an inch too short, you know the pain. That’s exactly why I keep a Sperry New Holland 840 Parts Catalog on the shelf next to the service manual. This isn’t some aftermarket compilation with blurry scans and missing pages. It’s the actual 90-page factory document that Sperry New Holland issued for the 840 model – printed in 1975 with a parts bulletin update dated May 1982. Every part number, every quantity, every revision note is pulled straight from the OEM line.

90 Pages of Factory Part Numbers – Grouped and Figured

The catalog breaks the baler into groups (1 through 8 based on the table of contents). Each group then splits into figures that show an exploded view of an assembly. Page 2 carries the issue date and the replacement history – this 496940 issue supersedes issues 496803 and 496820. That means if you saved an older parts list, you need this updated version to catch the serial-number corrections. The parts bulletin on page 3 flags changes like the floor weld assembly (part 411411) that applies only on and above serial number 112056. Ignore that and you’ll order the wrong floor pan. I’ve seen it happen.

Parts Bulletin Updates: What Changed and Why It Matters

Page 3 of this catalog is a parts bulletin insert – printed in bold for new information. It lists old part numbers crossed out and new ones assigned. For example, hex cap screw part 120111 now replaces the old 120111? Wait, that seems the same – check the bulletin: it says “NEW DRAWING WITH CORRECTION” for that screw, meaning the fastener spec changed even though the part number stayed. That’s the kind of detail you won’t find in a third-party reprint. The bulletin also shows new brackets, supports, and hydraulic hose routings for machines built after serial number 112056. If your baler is below that, you use the original parts. Above it, you follow the updated drawing. Without this bulletin, you’re guessing.

Using This Parts Catalog on a Model 840 Round Baler

This catalog is for the Sperry New Holland 840 round baler. It does not cover the 845, the 851, or any other model. Each group – from group 1 through group 8 – is laid out with figure numbers, part numbers, quantities, and descriptions in five languages (English, French, German, Italian, Dutch). If you need to order the hex lock nut for the tailgate hinge, you flip to group 5, figure 7, and find part 140096 with a quantity of 20. That’s it. No guesswork. The catalog also includes a “N.B.” column for notes like “Used on and above serial no. 112056.”

Why OEM Parts Catalogs Beat Aftermarket Copies

Aftermarket parts catalogs often compress drawings, drop the parts bulletin inserts, and ignore the serial-number splits. This Sperry New Holland document is the real deal – printed by Sperry Rand France for the European market, but the parts are identical to the North American 840 balers of that era. The part numbers are factory-original. You can cross-reference them with your local dealer’s system. If you’ve gotten burned by a generic “universal” catalog before, this is the cure. Sperry New Holland OM 352 Parts Catalog – 48 Pages of Factory Parts Data covers a different machine but uses the same numbering scheme. Sperry New Holland OM 352 Parts Catalog – 66 Pages adds more coverage for that engine family. And Sperry New Holland OM 401 Parts Catalog – OEM Factory Parts Data is another solid reference for the larger power units.

Serial Number Splits – Don’t Ignore Them

The parts bulletin on page 3 lists several “Used on and above serial no. 112056” notes. One example: the floor weld assembly changes from part 411411 to a new drawing of 411411 (same part number, different manufacturing specs). If you order the old version for a machine built after that serial, it might not fit. The catalog also shows a new plate (358287) and bracket (439811) that appear only on later machines. Always check the serial number of your 840 baler before ordering parts. The catalog gives you the exact cut-off.

Does this parts catalog include torque specifications?

No. This is a parts catalog, not a service manual. Torque specs are in the factory service manual for the 840 baler.

Can I use this to rebuild my 840 baler from scratch?

Absolutely, if you pair it with the service manual. The parts catalog gives you every nut, bolt, seal, and hydraulic line part number. For disassembly and reassembly procedures, you need the service manual. But for ordering the correct components – especially for serial-number-specific parts – this catalog is the only source that won’t steer you wrong. I’ve used it to source floor assemblies, lever assemblies, and even the obscure seal rings that most aftermarket catalogs skip. The exploded views show how the assemblies go together, but they don’t tell you the order of assembly or the tightness of each fastener. That’s why I keep both books on the bench.

What is the publication year of this manual?

The main catalog is originally 1975, but the included parts bulletin is dated May 1982. You get the latest factory updates.

Does this cover the hydraulic system?

Yes, group 7 covers the hydraulic components. You’ll find part numbers for hoses, seal rings, and fittings. See figure 14 for the hydraulic hose assembly part 442796.

Whether you’re a farmer maintaining your own equipment or a tech who’s tired of chasing wrong parts, this Sperry New Holland 840 Parts Catalog puts the right numbers in your hands. It’s 90 pages of factory data – no aftermarket guesswork, no missing bulletins. If you want to see how the automotive side handles parts documentation, take a look at the Automotive Industry Overview for a sense of the standard. And for another perspective on parts traceability, the Automotive Industry Overview also applies – the same principles of serial-number splits and supersession apply here.
