New Holland 1805, 1905, 2205, 2305CP 1993 Parts Catalog – OEM Factory Specs

If you’re working on a New Holland 1805, 1905, 2205, 2305CP 1993 Parts Catalog forage harvester and need the right bearing, chain, or sprocket, a generic parts list won’t cut it. I’ve seen guys order three different pulleys because the aftermarket cross-reference was off by a half-inch. This factory catalog – all 466 pages of it – gives you the exact part numbers New Holland assigned when these machines left the line in Zedelgem. No aftermarket translation, no “compatible with” guesses. Just the OEM breakdown.

Group 2 and Group 5: Engine and Powertrain Parts Breakdown

Group 2 (page 5) covers the engine block, cylinder head, and fuel system components. Group 5 (page 15) picks up the clutch and flywheel assembly. If you’re chasing a hydraulic pump leak or a worn PTO shaft, these two groups are where you start. The drawings show exploded views with callouts matching the part number tables. I’ve used this catalog to find a $12 seal that a parts house swore was discontinued – it was sitting right there in Group 5, still available.

What Groups 16 and 21 Cover in the Forage Harvester

Group 16 (page 20) is the header drive system – knife heads, shear bars, and the main driveline. Group 21 (page 24) handles the feed rolls and crop flow. If your machine is throwing slugs or the feed roll timing is off, you’ll want the part numbers from these sections. The supplement update (Issue 04-93) adds new drawings and pages for Group 21 – pages 101 and 113 are revised. Don’t use an older issue or you’ll order the wrong roll.

Supplement Pages: Why the 1993 Issue Matters

This catalog is the April ’93 issue, replacing the ’91 version. It includes new pages for groups 1, 3, 4, 5, 7, 8, 9, 10, 11, 13, 16, 19, 21, 22, 24, 27, 32A, 33R, 34A, 37, and 39. For example, Group 39 gets a new drawing and new pages 191, 193. If you own a 2305CP built after machine serial 8819001, those new pages are critical. The bold-type part numbers in the supplement are new – ignore them and you’ll order a discontinued part.

3 Reasons to Use the OEM Parts Catalog Instead of Aftermarket

One: Factory drawings show the exact orientation of seals, bearings, and snap rings – aftermarket catalogs often flip the view or omit hardware. Two: Part numbers here include supersession history. A number in bold means it’s the latest revision; the old number is still listed behind it. Three: You get the complete machine breakdown across 54 groups – from Group 2 (engine) to Group 54 (electrical). Aftermarket catalogs only list high-wear items and leave you guessing on brackets and fasteners.

Get the Right Part Number from the Factory Drawings

Every part number in this catalog ties back to a specific illustration. Need a feed roll bearing for a 1905? Flip to Group 21, find the exploded view, and read the callout number. Then cross‑reference to the table for the part number. I’ve done this a hundred times – the only way to be sure is the factory drawing. The microfiche reference (84005661 7) on the cover matches the original dealership system, so you can verify your order against the same data the dealer used.

Audience Fit: Farm Mechanics and Owner-Operators

This catalog is for anyone who owns a 1805, 1905, 2205, or 2305CP and wants to order parts without a trip back to the dealer. If you’re a DIY farmer with a shop in the barn, you know the frustration of buying a part that looks right but doesn’t fit. The 466-page format covers every nut, bolt, and bracket. I keep a copy in my tool box for a 1905 that comes in every season – it’s saved me hours of cross-referencing. Beginners can use it too: start with the group index, find the system you’re working on, and match the drawing to your machine.

For context on how these parts catalogs fit into the broader history of agricultural equipment, you can read the Automotive Industry Overview on Wikipedia. The same engineering rigor that went into automotive parts documentation applies here.

Source Validity: OEM Original vs. Aftermarket Reprints

This isn’t a scanned third-party compilation. It’s the original New Holland Parts Catalogue 9512519 2, issued by New Holland Belgium N.V. – same document the factory sent to dealers. The supplement pages are included, so you have the latest revisions as of April 1993. Aftermarket parts lists often miss the bold-type updates or reprint old groups without the supplement. I’ve caught three different aftermarket catalogs with wrong part numbers for Group 35 (page 53) – the cam track assembly. This one has it right.

If you’re also working on other New Holland equipment, Ford New Holland 853 1993 Parts Catalog – OEM Baler Manual covers the baler line. Ford New Holland 568 1991 Parts Catalog – Factory OEM Manual is useful for hay tools. And Ford New Holland 1915 1993 Parts Catalog – Factory OEM Manual handles a different forage harvester model.

For a broader look at agricultural machinery documentation, Automotive Industry Overview provides background on how OEM standards developed.

Does this catalog include part numbers for the 2305CP model?

Yes.

How does the supplement update work, and do I need it if I have a 1991 catalog?

The supplement (Issue 04-93) replaces and adds pages for 21 groups. If you only own the 1991 version, you are missing critical revisions. For example, Group 3 has a new drawing and new pages 9,11,13 – the old part numbers for the feed roll housing may have been superseded. The supplement includes bold-type new numbers. Without it, you risk ordering obsolete parts. This catalog contains both the base groups and the supplement, so you have the complete, up-to-date reference.

I’ve been turning wrenches since before some of you were born, and I’ve seen what a wrong part number costs in downtime. This New Holland 1805, 1905, 2205, 2305CP 1993 Parts Catalog is the same book a factory-trained dealer tech uses. Access the Factory Manual and get the right part number the first time.
