Case IH Parts Lookup: How to Find the Right Part Number

A Case IH parts lookup starts in MyCNHStore, the CNH catalog that also holds CASE Construction parts in a separate storefront: farm equipment under Case IH, backhoes, skid steers and excavators under CASE. Search by serial number, open the catalog that covers your serial range, and match the diagram callout to the part number before you order.

Key Points

• The official catalog: MyCNHStore, run by CNH. Diagram pages open without an account, and orders go through a dealer you choose.
• Which storefront: Case IH for tractors, combines, hay and tillage equipment, including pre-1985 J.I. Case and International Harvester machines. CASE for backhoes, skid steers, track loaders, excavators, wheel loaders and dozers.
• Ways to search: part number, part name, model or serial number.
• Reading a page: the reference number on the drawing points to a row with the part number, quantity and notes.
• Why one model has two catalogs: CNH splits catalogs where the build changed, such as the 1070 Agri-King at serial number 8675001.
• Before you order: confirm the serial range, compare the old part, and measure glass and springs.

Where Is the Official Case IH Parts Catalog?

Case IH's own parts and service page sends you to MyCNHStore, the genuine parts store CNH runs for its brands. CASE Construction's site does the same: "Visit MyCNH Store for CASE parts and order now for pick up or shipping." It is one platform with a storefront per brand, and Case IH describes the diagrams in it as model diagrams direct from the manufacturer.

What the store lets you do:

• Search four ways: by Genuine Part number, part name, model or machine serial number.
• Browse diagrams: numbered callouts and exploded views for each assembly.
• Save your machines: registered users keep an equipment list with serial number or PIN, model code and production date, then search by those saved models.
• Order through a dealer: pick a dealer, add parts to a pick list, and choose pickup or delivery.

One tool on the Case IH site causes confusion. The box that asks you to "enter your make and model" is the Lube Lookup, which matches fluids and lubricants. For parts, go to the catalog itself.

Is Case IH the Same as CASE Construction for Parts?

No. The two share a history and a parent company, but CNH runs them as separate brands: Case IH in agriculture and CASE Construction Equipment in construction. Case IH was formed in 1985, when the J.I. Case and International Harvester (McCormick) legacies were united in one brand. In the catalog, that history decides where an older machine is filed.

A J.I. Case farm tractor built before the merger, such as the 1070 Agri-King, sits under Case IH. An older Case loader backhoe such as the 580C Construction King sits under CASE. If a search comes back empty, switch storefronts before assuming the machine is missing.

What Do I Need Before I Start a Case Parts Lookup?

Gather four things before you open the catalog. In our experience, most fitment questions start with a lookup done from the model name alone, and the model name is the least precise piece of information you have.

• Model designation: from the decal or the operator's manual.
• Full serial number or PIN: from the machine's plate. Our guide to finding the serial number, year and model on your Case equipment covers where the plate is and what the characters mean.
• Engine identification: the engine is identified separately. The 580SN Tier 4a catalog, for example, lists its engine by its own code, F5HFL413B A001.
• The old part: any number cast, stamped or printed on it, plus photos and measurements.

With those in hand, the lookup takes minutes instead of guesswork.

How Do I Search the Case IH Parts Catalog by Model or Serial Number?

The catalog takes a serial number, a model name or a part number in the same search bar. A serial number search is the most precise, because it points you toward the catalog for your build. A model search is a fine start, but one model can return several catalogs.

1. Open the right storefront: Case IH for farm equipment, CASE for construction machines.
2. Search the full serial number or PIN. If you only have the model, search that instead.
3. Pick the catalog whose title matches your machine. Titles carry serial and date ranges, for example "580SN - Backhoe Loader - Tier 4a - From Pin NCC564000 (07/11 - 04/15)".
4. Work down to the section and page for the area you are repairing.
5. Save the machine to your equipment list if you will come back to it.

If you already have a part number from the old part, search it directly. A part number search skips the catalog tree and is the fastest route to a single item.

How Is a Case IH Parts Catalog Organized?

Each catalog is a tree. On the Case IH 695 tractor, the path reads Case IH, North America, Tractors, Agricultural, Under 100 HP, 695 Case IH Tractor, Pictorial Index, then page 1-02, Product Identification and Serial Numbers. Newer catalogs use longer codes: the 580SN WT backhoe opens with section 00, General and Pictorial Index, and page codes such as 00.000.00.

• Brand and region: Case IH or CASE, then a region such as North America.
• Equipment type and model: tractors, loader backhoes and so on, down to your model.
• Catalog: one per serial range or emission tier where the build changed.
• Section and page: numbered groups of diagrams, with one assembly per page.

Watch the region level. Catalogs are tagged by region, so a machine built for another market may be filed in a different regional catalog.

How Do I Read a Case Parts Diagram?

Every diagram page pairs a drawing with a parts list. The numbers on the drawing are reference numbers, not part numbers. Each one points to rows in the list, which on MyCNHStore has columns for Ref., Qty, Part #, Alts and Description. Here are real rows from the 580CK Series B backhoe control valve page:

A reading routine that works on any page:

• Find the component on the drawing first, then note its reference number.
• Filter the list to that callout. MyCNHStore can show the rows for one callout only.
• Read the quantity before you assume a part is single.
• Read the description to the end. Production notes and "order" instructions sit there.
• Check the Alts column for alternative numbers listed against the row.

Rows marked NSS trip people up most. The drawing shows the part, but it is sold only inside an assembly or a kit.

Why Does One Case Model Have Several Catalogs or Part Numbers?

Because parts change at serial numbers, not at model names. When the build changes mid-run, the catalog either splits at that serial or lists both versions under the same callout.

The Case 1070 Agri-King shows the first pattern. It has two catalogs: "Prior to S/N 8675001 (01/69 - 12/78)" and "S/N 8675001 & After (01/72 - 12/78)". Both date ranges include 1972 through 1978, so the build year cannot tell you which one to open. The serial number can.

• Catalog splits: separate catalogs by serial range, like the 1070, or by emission tier, like the 580SN Tier 4a catalog that starts at PIN NCC564000.
• Early and late production rows: one callout with two numbers, like the 580CK control valve above.
• "Order" notes: an older number that tells you to order a newer one. Treat the newer number as the one to buy and verify.

The 580 line shows how many builds can sit behind one model name. Our guide to Case 580 backhoe specs and parts by generation walks through them.

How Do I Confirm a Case Part Fits Before I Order?

A number from the catalog is a candidate until you have checked it against the machine. These checks catch most mismatches:

• Serial range: confirm your serial number falls inside the catalog title or row note you used.
• The old part: compare it with the drawing, including mounting points and connections.
• Measurements: glass, springs and seals are where measuring matters most. Our 580M Upper Rear Glass replacing Case 352208A1 lists 42.5" x 32.5", and our Rear Window Spring replacing Case 1343825C1 lists a 12.785" overall length.
• The OEM number: match it against the aftermarket listing you plan to buy, then read that listing's fitment.

Listing fitment is where to start, not where to stop. The 352208A1 listing shows fitment for the 580M tractor-loader-backhoe, and the 1343825C1 listing shows fitment for 7110 to 7150, 7210 to 7250 and 8910 to 8950 agricultural tractors. Customers are responsible for verifying fitment, so send your serial number and the OEM part number to sales@partsonline.com and we will check it against your build.

What If My Case or IH Machine Is Old or Not Listed?

Older machines are better covered than most owners expect. The CNH catalog still holds 1970s machines such as the 1070 Agri-King and the 580C Construction King backhoe, plus International Harvester equipment such as moldboard plows under Case IH.

When a search still comes up empty:

• Try the other storefront, and try the model with and without names such as "Agri-King" or "Construction King".
• Search the number on the old part. Numbers often survive on castings and housings long after decals fade.
• Use the engine identification for engine parts.
• Search aftermarket catalogs by the OEM number. Our Quarter Window Glass replacing Case 1250436C2 lists fitment for International tractors from 1976 to 1987, including the 786 to 1586 and the 3088 to 3788.

Can I Get a Case IH Parts Catalog as a PDF?

We found no official free PDF download of Case IH or CASE parts catalogs. The official parts catalog is the online one, and it is free to browse. Manuals work differently:

• Case IH operator's manuals, 2007 and newer: free through Case IH's online owner portal.
• Case IH operator's manuals before 2007: sold through CNH's Document Management Center.
• CASE Construction: its site links to the same Document Management Center for operator manuals and specifications.
• Parts lists: save parts to a pick list in the catalog and take the numbers to your dealer or supplier.

If you buy an unofficial reprint of an older parts book, check that the serial range printed on it covers your machine.

How Do Aftermarket Parts Cross-Reference to Case Part Numbers?

An aftermarket cross-reference maps a Case or Case IH OEM number to a replacement built to the same specification. The OEM number is the anchor, which is why our listings are titled by the number they replace rather than by machine.

Case numbers come in several shapes: letter-prefixed numbers such as R52880, numbers with a suffix such as 338429A1 or 1250436C2, and eight-digit numbers such as 84226258. CNH does not publish a decode of these shapes, so treat the shape as a way to recognize a Case number, never as proof of fitment.

Cross-references also show how much the two brands share. Our Hydraulic Filter replacing Case 84226258 lists fitment on both sides:

• Case IH tractors: Maxxum, Magnum 225 to 335, Puma AFS Connect, CVX, CS, MX, MXM, MXU, Quantum and Vestrum models.
• CASE backhoes: 580SM+, 580 SLE Serie III and 590 SLE.
• CASE wheel loaders: 721D, 721E, 721 E T3 and 821 E T3.

Quality aftermarket parts are built to meet or exceed OEM specifications. Browse the full range in our Case parts collection, and verify by serial number before ordering. Consult a certified mechanic for complex repairs.
