CASE IH 2366 Parts Catalog – 881 Pages of Factory Specs

I’ve been torquing bolts since before some of you were born, and let me tell you what irritates me: guys who trust a third-party parts list when they’re rebuilding the rotor drive on a CASE IH 2366 combine. You get halfway through the job, the belt you ordered is the wrong width, the chain length is off by two links, and now you’re down a day of harvest. This CASE IH 2366 Parts Catalog is the factory document, 881 pages of nothing but the real part numbers, the exact diagrams, and the torque values that CASE IH stamped on the line. No reprints, no guesswork, no aftermarket “equivalent” that turns into a headache.

I pulled this job last week on a 2366 that had a shredded separator belt. Owner had bought a generic replacement from a farm store. Belt lasted three hours. I cracked open this catalog, found Figure 09A-06 (separator drive), cross-referenced the OEM part number, and had the right belt on order before lunch. That’s what this catalog does. It saves you the phone call to the dealer and the second trip to the parts counter.

Belt and Chain Diagrams – Figure 01-19

The first section you’ll use is 01-19, titled “BELTS – CHAINS.” This is the core of the whole machine. The manual lists each belt and chain by reference number, then directs you to the exact figure for the drive. Rotor drive? Figure 09A-03 and 09B-02. Cleaning fan drive? Figure 09C-06. Each line gives you the OEM part number, quantity, and description. Page 2 of the catalog shows belts 1–14, chains 20–28. If you’re replacing the feeder conveyor chain (chain 27), the manual says “See Figure 09A-22.” You flip to that figure and you get the exploded view with every roller, sprocket, and tensioner part number listed. That’s how you avoid ordering the wrong pitch chain.

Radiator and Fan Shroud – Section 02-01(01)

Another section I’ve used repeatedly is 02-01(01), covering the radiator and fan shroud. For the 2366 up to serial number BSN JJC0177700, the manual gives you the 15 psi radiator cap (part A170241), the shroud (251462A1), and the seals – 865 mm (34 in) cuts from 1974883CX. It also lists the shock absorbers (R29799) and the lower front support (195095A2). I’ve seen guys try to patch a leaking radiator with a universal hose clamp and some silicone. That works for about an hour. This catalog gives you the exact 660 mm lower hose (1979382C2) and the correct worm-gear clamps (214-3248). You replace it once, right.

Torque Specs and Fastener Data

This is a parts catalog, not a service manual, so torque specs aren’t listed for every bolt. What you do get is the exact hardware – bolt grade, thread size, and length – for every assembly. The radiator section lists bolts 409-7512 (5/16”-18 x 3/4”, serrated flange), lock washers 492-11031, and nuts 488837C1. When you order those, you get the correct clamp load. If you need the actual torque value for a head bolt or a main bearing cap, you’ll want the service manual, but the parts catalog is what you use to make sure you’re installing the right fastener in the first place. You can find related factory manuals like the CASE IH 7210, 7220 Parts Catalog – Factory Specs or the CASE IH JX 70U, MX 80C, 90C, 100C, MX 100 Parts Catalog if you’re working on other models.

Who Needs This Catalog?

If you own a 2366 case ih axial-flow combine (EU spec, built between October 1997 and August 2004), you need this. I don’t care if you’re a full-time mechanic or a farmer doing your own repairs in the shed. The parts breakdowns save you from disassembling half the machine just to find a part number stamped on a rusted bracket. You open the catalog, find the figure, read the part number, call the dealer. Done. For a home garage mechanic who’s never touched a combine, this catalog will still make sense – the diagrams are clear, the reference system is consistent, and every item has a quantity. Beginners can use it to cross-check their work. Pros use it to avoid billing a customer for a wrong part.

Why OEM Documentation Beats Aftermarket

Aftermarket parts catalogs often re-number parts, skip hardware, or lump different serial number breaks into one generic list. This is the original CASE IH print. Every page is scanned from the factory binder. The part numbers are the same ones CASE IH used when the combine left the assembly line. For example, the rotor drive speed adjustment on page 3 is marked “Not Illustrated” because it’s an adjustment procedure, not a replaceable part – the aftermarket catalogs I’ve seen just leave it out or invent a diagram. That kind of omission costs you time. The original also includes the correct units – imperial fasteners, 5/16”-18 bolts, 7/16”-14 carriage bolts – not metric conversions that strip out your threads. If you want to understand how the Automotive Industry Overview handles part numbering, this is a perfect case study, but for your combine, stick with the OEM spec.

Frequently Asked Questions

Does this parts catalog include torque specs for the engine?

No. This is a parts catalog, not a service manual. It lists part numbers, quantities, and reference figures. For torque values you need the factory service manual for the 2366.

Can I use this catalog to find the belt for the cleaning fan drive?

Yes. Open section 01-19, look for belt number 10. The description says “Cleaning Fan Drive” and directs you to Figure 09C-06. That figure shows the belt routing and the OEM part number for the belt. You order that exact number and it fits. I’ve done it on a 2366 that had a shredded belt – took five minutes to find the part in the catalog, two days to get the belt, and an hour to install. No guesswork.

You can also check out the STEIGER 385 / 435 Radiator and Hoses Parts Catalog if you work on those heavy tractors. For the internal combustion engine specifics on axial-flow combines, the Internal Combustion Engine article gives good background, but nothing replaces the OEM manual. This catalog is 881 pages of factory data – no fluff, no reprints, no shortcuts. Access the Factory Manual and keep it on your bench or in your tablet case. You’ll use it before every major repair on that 2366.
