Mccormick B-100 Parts Catalog – What a Real Shop Needs

You’ve got a Mccormick B-100 in the bay, and the parts book your buddy handed you was printed on toilet paper. I’ve been there. The wrong part costs you a day, sometimes a head gasket. That’s why this factory Mccormick B-100 Parts Catalog matters. It’s 198 pages of original International Harvester engineering, not some aftermarket rewrite that guesses at bolt sizes. Page 1 lists the thread standard they used: UNC and UNF, every diameter from 1/4 to 1-1/2 inch. When you need the camshaft assembly, flip to page 6. That’s real data, not a reprint from a third party that swapped a part number.

I’ve seen techs strip threads because they grabbed a metric bolt for an SAE hole. This catalog tells you exactly what thread pitch goes where – National Coarse unless specified, hex nuts unless otherwise stated. You want to know if that fuel pipe takes a 5/16-18 or a 3/8-16? It’s in the fuel section. No guessing, no “close enough.” That’s the difference between a repair and a redo.

Diesel Engine Breakdown – Camshaft, Crankshaft, and Cylinder

The engine section alone covers the camshaft (page 6), crankshaft (page 7), cylinder head (page 3), and crankcase with front cover. Every part number is tied to the original IH drawing. If you’re rebuilding the bottom end, the piston and connecting rod groups are listed on page 18. The flywheel with ring gear is on page 17. You don’t have to cross-reference three different manuals – it’s all right here.

What Fastener Specs Are Provided?

Bolts are listed with diameter and thread count per inch. Page 1 gives you the full table: 1/4-20, 5/16-18, 3/8-16, all the way up to 1-1/2-6. Washers are plain unless marked, cotter pins are extended prong unless specified. This level of detail saves you from throwing a mismatched fastener into a critical assembly. I’ve seen what happens when someone uses a fine-thread bolt where a coarse belongs – it cracks the casting.

3 Reasons OEM Parts Catalogs Beat Aftermarket

First, the part numbers are direct from International Harvester – no re-indexing or translation errors. Second, the illustrations match the actual hardware on your B-100, not a generic silhouette. Third, the serial number locations are printed right in the book: engine serial on the right side of the crankcase, chassis serial on the dash panel plate, loader serial on the right carrying frame. An aftermarket book will skip that and leave you hunting.

Fuel System: Injection Nozzle and Simms Pump

The fuel section is dense. It covers the injection system (page 21), the injection nozzle (page 23), fuel pipes for the engine (page 35), oil return pipe (page 33), and the Simms injection pump (pages 27 and 32). There’s also a glow plug listing for Simms (page 23). If you’re chasing a fuel leak or replacing injectors, having the correct part number for the bowl-less fuel filter (page 34) means you order once.

Get the Cylinder Head and Crankshaft Diagrams Right

The cylinder head assembly on page 3 includes the intake manifold (page 5) and exhaust manifold (page 3). The crankshaft page (7) shows the main bearing layout. You also get the oil pump (page 34), water pump assembly (page 39), and thermostat housing (page 38). Every gasket, seal, and bolt is listed with its IH part number. That’s how you avoid buying a head gasket set that doesn’t fit the 4-cylinder diesel in your B-100.

Look, I don’t care if you’re a farmer fixing your own loader or a shop owner with a line of tractors waiting – this catalog is the only way to be sure you’re ordering the right steel. Don’t trust a photocopy or a PDF that’s been scanned twice and lost resolution. This is the original factory file, 198 pages, direct from the IH archives.

Does this catalog include torque specs or repair procedures?

No, it’s a parts catalog – no repair steps. You get part numbers, diagrams, and fastener specs only.

How are bolts and washers specified in this manual?

Bolts are UNC or UNF with thread count per inch. Washers are plain unless marked “lock” or “light.” All definitions are on page 1 of the catalog. That page explains that National Coarse thread is standard, hex nuts are assumed unless cap screws are called out, and cotter pins are extended prong. If you don’t read that intro page, you’ll order the wrong hardware. I’ve had guys grab a lock washer when the book called for plain – then wonder why the bolt backed off. Read the rules at the front, same as you’d read a torque chart before you pull out the wrench.

What models does this catalog cover?

Specifically the Mccormick B-100 tractor. It does not cover B-275, B-414, or other variants.

Is this a printed book or a digital access?

It’s a digital PDF format – 198 pages, searchable, printable. You can view it on a tablet in the shop, which beats flipping greasy paper.

You want the exact part that keeps your B-100 running without extra trips to the dealer. That’s what this factory catalog gives you.
