CASE IH Magnum 310, Magnum 225, Magnum 250 Parts Catalog – Factory OEM Specs

You ever order a part for a Magnum 310, get it in your hands, and find it’s the wrong diameter, wrong thread pitch, or the mounting holes don’t line up? That’s the cost of guessing. A factory CASE IH Magnum 310 parts catalog kills that guesswork before you pick up a wrench. I’ve seen guys waste half a day on a radiator swap because they ordered the wrong shroud bracket. This is the document that keeps you from being that guy.

This is an original OEM Parts Catalog covering the Magnum 310, Magnum 225, and Magnum 250. It’s 59 pages of factory-issued part numbers, exploded-view drawings, and quantities. No aftermarket reinterpretation. No third-party reprints. You get the same pages the CASE IH dealer parts counter uses when you call in a VIN. If you’re rebuilding an engine cooling system or replacing a fan shroud, you want these exact part numbers — not some abbreviation from a shady online database.

7 Systems Covered in the Parts Catalog

The catalog breaks down the tractor into major assemblies. Engine, cooling, hydraulic, drivetrain — each section starts with a clear diagram and a table listing every part, its number, quantity, and description. For example, the radiator and fan shroud subsection (page 1 of the PDF) shows the fan, viscous drive, brackets, seals, and all associated hardware. Need a M8 x 16 hex flange bolt? You’ve got the part number right there. That kind of detail saves a trip back to the parts store. Other sections cover the charge air cooler, oil cooler, and mounting hardware. Everything is keyed to the Magnum 310, 225, and 250 specifically.

Radiator and Fan Shroud Section: A Closer Look

Flip to the engine section and you’ll find exploded diagrams for the radiator assembly. The catalog lists two radiator options: one for the Magnum 225 and 250, another for the Magnum 280 and 310. Each assembly breaks down into its components — core, fan blades, viscous drive, brackets, seals. You get both the standard performance fan (8-blade, 127 mm ID) and the suspended axle fan (177 mm ID) with separate viscous drive assemblies. For every seal, every bracket, every M6 or M8 nut, there’s a factory part number. That’s the level of precision you need when the local dealer only has an hour before closing.

Why Factory Parts Catalogs Beat Aftermarket Lists

Aftermarket sites cobble together parts from multiple sources. They’ll list a “replaces OEM #87390680” radiator that may or may not match the original mounting. A factory CASE IH parts catalog doesn’t guess. It gives you the OEM number, and you order directly against that. No guessing about thread pitch or whether the seal is the right durometer. I’ve seen a $20 gasket turn into a $400 job because the aftermarket cross-reference was wrong. This catalog eliminates that risk. It’s the same document the dealer pulls up on his terminal. If you want to compare, check the CASE IH 7210, 7220 Parts Catalog – Factory Specs for another example of factory-level detail.

Does This Catalog Cover the Fuel System?

The 59 pages focus on the major assemblies — engine, cooling, hydraulic, electrical, cab, and drivetrain hardware. Fuel system components (injectors, lines, filters) are included where they appear on the diagrams. The catalog is primarily a parts identification tool, not a repair manual. It won’t tell you how to time the injection pump. But it will get you the right part number for that high-pressure line. For a step-by-step procedure, pair it with a factory service manual. I’ve linked a related catalog for the CASE IH JX 70U, MX 80C, 90C, 100C, MX 100 Parts Catalog if you need smaller-frame tractor parts.

Who Needs This Catalog

If you’re a shop owner, a farm mechanic, or a serious owner-operator maintaining a fleet of Magnum series tractors, this catalog belongs next to your tool box. The 59 pages cover all three models — Magnum 310, 225, and 250 — with the same exploded views and part tables. You don’t need internet access in the field. You don’t need to call a dealer and wait. You look up the diagram, note the part number, and place your order. It also cross-references hardware like bolts, washers, and nuts — the small stuff that holds the big stuff together. For the DIY guy restoring a Magnum 225, this is the shortcut to a correct rebuild. The CASE IH STEIGER 385, STEIGER 435 Parts Catalog – Factory OEM Manual covers the bigger row-crop tractors if your operation scales up.

3 Reasons to Use Factory OEM Documentation

1. Correct part numbers – No substitution errors. The catalog lists the exact CASE IH number. Order it, bolt it on, it fits.
2. Complete assemblies – The exploded diagrams show every fastener, gasket, and seal. You won’t realize midway that you forgot a bracket.
3. Time savings – One look at the diagram and you know what you need. No backtracking, no returns. That means you’re turning wrenches, not running errands.

Frequently Asked Questions

Is this a service repair manual or just a parts list?

It’s a factory parts catalog. It doesn’t contain step-by-step repair instructions. Use it to identify and order the correct OEM parts for your Magnum 310, 225, or 250.

How many pages is the catalog?

59 pages total, covering all three models. Each page has exploded diagrams and tables with part numbers, descriptions, and quantities.

Are the diagrams specific to each model, or generic for the series?

The diagrams are specific. For example, the radiator assembly has separate figures for the Magnum 225/250 and the Magnum 280/310. The part numbers are different. This catalog captures those differences. If you order the wrong fan bracket, it’s because you didn’t check which figure applied to your tractor, not because the catalog was wrong.

Can I use this catalog if I have a Magnum 280 or 335?

Some sections include the Magnum 280 and 335 where the parts are shared (like the radiator assembly for 280/310/335). But the catalog title covers 310, 225, and 250. For a Magnum 335, you’d want a catalog specifically for that model to be certain you get the correct hardware.

You don’t need to hope the part fits. You need the part number that CASE IH designed for your machine. Access the Factory Manual now and keep your Magnum 310, 225, or 250 running with original OEM parts.
