New Holland 1900, 2100, 919S 1988 Parts Catalog

I’ve torqued head bolts on everything from a 1968 Farmall to a modern Case IH, but nothing wastes shop time faster than ordering the wrong part because you trusted an aftermarket parts list. That’s why when a customer rolls in with a New Holland 1900, 2100, or 919S — whether it’s a forage harvester or a sicklebar — I pull the factory catalog. The one you’re reading is the real thing: 1988 factory issue, 364 pages thick, printed by New Holland themselves. No reprints, no photocopies, no generic part numbers that cross-reference to the wrong bearing.

You’ve been chasing a part all morning, maybe a feed roll slip clutch or a cutterhead gearbox seal, and the online listings give you three different numbers. That’s the pain — wasted money and time. This catalog ends that. It was written for dealers and mechanics who need exact OEM part numbers, not “equivalent” or “fits similar”. Every exploded view is keyed to a part number, and the general information on page 2 makes it clear: hardware is listed separately and not included with the assembly. None of that ambiguity.

Parts Breakdown for the 1900 and 2100 Forage Harvesters

The catalog is organized by groups — AIR CLEANER, 1900 on pages 218-219; AIR CLEANER, 2100 on 230-231; ALTERNATOR, 1900 through 220-227; ALTERNATOR, 2100 through 238-247. That’s for the engine electrical. The cutterhead housing for the 1900 (ASN coded) covers pages 24-27, and for the 2100 it’s on 201, 221, and 223. Brake gearbox? Page 88. The filler chart is inside the back cover, so you can check fluid capacities without flipping through the whole book. I’ve used the blower section (80-87) to rebuild a clogged unit on a 2100 — the part numbers matched perfectly.

What Makes This Parts Catalog Different from Aftermarket?

Aftermarket parts catalogs often merge multiple models into one generic list, then leave out the serial number breaks. The 2100 above serial number 404591 is covered separately in this book. The 919S sicklebar is included as a separate model. Page 3 shows the model identification for the 1900 and 2100 harvesters. You won’t find a “one size fits all” listing here. New Holland printed this specifically for the 1900, 2100, and 919S — three distinct machines. The genuine parts catalog is the only source that gives you the exact OEM part number for each nut, bolt, and gasket. If you’re rebuilding a 919S sicklebar, the part numbers for the knife sections and ledger plates are in there, not cross-referenced from a different model.

Use the Filler Chart Before Ordering

Inside the back cover — literally a physical chart — is the filler chart for capacities. In a shop, you need that before you order a new hydraulic pump or a transmission seal. If you overfill because you guessed, you blow seals. The catalog lists the correct fluid type and quantity for each system. I’ve had to redo jobs because someone used a generic service manual’s fluid spec instead of the factory chart. This eliminates that.

AIR CLEANER Section: Exactly What You Need

Look up the air cleaner group for the 1900 (pages 218-219) and you’ll see the pre-cleaner, the element, and the mounting brackets exploded with callouts. Same for the 2100 (230-231). The part numbers are New Holland OEM. If you need an engine fan for the 2100, page 240 shows it. The alternator group for the 1900 runs 220 through 227, which includes the regulator and wiring harness parts. No guessing which voltage regulator fits because the illustration shows the exact bracket.

364 Pages of Factory Part Numbers

That’s the thickness you get — 364 pages of parts listings, illustrations, and ordering instructions. The back cover includes the filler chart. The general information section (page 2) explains how hardware is listed: the part preceding the hardware listing uses those fasteners. You don’t get duplicate hardware with the assembly. That’s a small detail that saves you from ordering a mounting kit when you only need the bolt. If you want to cross-check with other manuals, check the New Holland 1800 1900 Forage Harvester Parts Catalog for the 1800 series, or the New Holland 1900 Parts Catalog – Factory OEM 112 Pages for a shorter version. For a baler manual, the Ford New Holland 853 1993 Parts Catalog – OEM Baler Manual is also available.

For background on why OEM documentation is critical in the agricultural industry, the Automotive Industry Overview provides context on parts standardization. Another Automotive Industry Overview explains the evolution of OEM versus aftermarket supply chains.

Can I use this catalog for a 919S sicklebar?

Yes. The catalog explicitly covers the 919S model. The front cover lists it, and the contents include groups (like cutterhead, feed roll) that apply to the sicklebar configuration. Part numbers are specific to that machine.

What if I need a part number for a pre-serial number 2100?

This manual covers the 2100 above serial number 404591. For earlier machines, you need the previous issue. That said, many groups (like the air cleaner or standard axle) remained unchanged. The catalog lists ASN (after serial number) breaks where applicable, for example the cutterhead housing for the 1900 has pages 36-37 for specific ASN. If you’re working on an older machine, check the group pages for the 1900/2100 and verify the illustration matches your unit. The filler chart and general hardware listings are still applicable across serials. But for exact numbers, you must match the serial range. I’ve used the belt and chains section (pages 10-11) on a 1986 1900 without issue because the belt routing didn’t change until the 1990 update. New Holland reserved the right to make running changes — stated on page 2 — so always verify against your machine’s actual part. Don’t rely on online guesses. This catalog gives you the factory baseline.

Downtime on a forage harvester during harvest costs money. Having the right part number the first time saves you an extra trip to the dealer. That’s why I keep this catalog within arm’s reach of the phone. The factory parts catalog is the only way to be sure you’re ordering what actually bolts on. Access the Factory Manual and put it on your tablet or print the pages you need. Your parts counter will thank you.
