CASE IH 7120, 8120, 9120 2013 Parts Catalog

Back in my shop, nothing ticks me off faster than ordering a part from a third-party catalog that doesn’t match the machine sitting on the lift. You grab what you think is the right hydraulic cylinder for a CASE IH 7120, 8120, 9120 2013 Parts Catalog, find out the stroke is off by half an inch, and now the customer’s combine sits another week. That’s why this CASE IH 7120, 8120, 9120 2013 Parts Catalog is what I keep on the shelf next to my torque wrenches. 2588 pages of factory-sourced part numbers, exploded diagrams, and supersession data straight from CNH. No guessing. No wasted trips to the dealer.

Section 00 General – The Combine Breakdown Codes

Open this catalog and the first thing you’ll hit is Section 00 General. It runs over a hundred pages dedicated to the 20 series Combine 1365 through 1468 and beyond. Each entry carries the figure number 84301008, which is how CNH tracks every variation in the 7120, 8120, and 9120 line. If you need a specific bracket, panel, or wiring harness for a 20 series combine, this section is where you start. The codes are consistent across the whole machine, so once you learn to read them, you can jump to any assembly.

Section 10 Engine – Finding the Right Gasket and Bolt

Section 10 Engine breaks down the powerplant into sub-assemblies: 10.000.00 covers the cylinder head, block, and oil pan; 10.001.02 gets down to the pistons and rings; 10.012.04 deals with the fuel system. Each sub-section lists the exact part number for every gasket, bolt, and seal. Example: for a 4-3/4 inch stroke hydraulic cylinder, the catalog lists part number 396137A2 with a note that it supersedes earlier versions built before January 1985. That level of detail saves you from ordering the wrong seal kit.

How to Use This Parts Catalog – Reading the Figure Numbers

The index on page 3 of the catalog explains the numbering system. Each figure has a figure number, a sequence code, a page number, and a print date (month/year). The call-out numbers in the diagram correspond to a table with REF, FN, PART NUMBER, YR/SN range, QTY, and DESCRIPTION. For example, REF 1 is the cylinder assembly, REF 2 is the fitting, REF 3 is the breather. Pay attention to the YR/SN column – it tells you if a part was used before or after a specific serial number break. Ignore that and you’ll get a part that doesn’t fit.

OEM Parts Data: Why Aftermarket Catalogs Don’t Cut It

Aftermarket parts catalogs often leave out supersession chains or list a generic part number that crosses to fifteen different machines. This document is an original OEM print from CNH America LLC, issued March 2013. It includes the exact part numbers that CASE IH dealers use. If you see {402475A2} in brackets, that means it’s a kit – the parentheses around a part number indicate it’s not serviced separately. Third-party reprints routinely miss those details. Stick with the factory source.

Who Needs 2588 Pages of Part Numbers?

If you own a 7120, 8120, or 9120 combine and do your own wrenching, this catalog belongs on your desk. Salvage yards use it to identify pull-off parts. Mechanics rely on it to verify the correct replacement when a customer brings in a machine with swapped components. Even if you only need one filter, having the full catalog ensures you get the right thread pitch and bypass setting. Pair it with a repair manual for the full picture. Consider the CASE IH 7210, 7220 Parts Catalog – Factory Specs if you work on later models. For compact tractors, the CASE IH JX 70U, MX 80C, 90C, 100C, MX 100 Parts Catalog covers a different lineup. And if you run row-crop tractors, the CASE IH STEIGER 385, STEIGER 435 Parts Catalog – Factory OEM Manual is another factory document you can trust.

For a broader understanding of how these powertrains work, check the Internal Combustion Engine entry – it covers basics, but your parts catalog tells you which piston ring goes where. Similarly, an Automotive Industry Overview gives context on why OEM parts matter for long-term reliability.

FAQ – Common Questions About This Parts Catalog

Does this catalog cover all 7120, 8120, and 9120 models?

Yes, all three models are fully covered in the same document.

Can I use this to order parts from a CASE IH dealer?

Absolutely. Every part number in this catalog is a genuine CNH number. Hand your dealer the REF number from the table and they will pull the correct bin location. Keep in mind that some parts may have been updated since the 2013 publication, but the catalog lists superseded part numbers so you or the dealer can cross-reference the latest revision. The YR/SN columns tell you exactly which serial range each part fits, so you avoid ordering a pre-85 cylinder for a 1998 machine.

What about the 20 series combine variants listed in Section 00?

Section 00 lists individual 20 series combine codes (84301008 1365 through 1468). Each code corresponds to a specific configuration – for example, a 7120 with a certain header or wheelbase. If your machine falls under one of those codes, the part numbers in the following sections apply directly. If your serial number isn’t listed, call your dealer with the machine’s full serial number and they can match it to the correct code.

Is this the same as a service manual?

No. This is a parts catalog for ordering components. It shows exploded views, part numbers, and quantities. It does not contain torque specs, diagnostic procedures, or repair instructions. You need a separate service manual for that. But for buying parts, this is the only source you should trust.

Stop burning time on bad part numbers. Access the Factory Manual now and start ordering parts that fit.
