Case 108 Parts Catalog – What You Need on the Bench

I’ve been wrenching for 28 years, and I’ve lost count of how many times I’ve seen a guy hold up a greasy part, squint at a blurry aftermarket diagram, and order the wrong piece. That costs time and money. When you’re working on a Case 108 Compact Tractor, you need the factory parts catalog – not some reprint, not a digital copy of a copy. This is the real thing: Case 108 Parts Catalog No. A1226, 23 pages, original OEM print. It replaced the previous issue – 1226 – which is obsolete. Throw the old one out.

Engine Section: Camshaft, Crankshaft, Cylinder – Page 5

If you’re tearing down the engine – and on a 108, you probably will be – the engine section starts on page 5, grid A6. That’s where you’ll find the Camshaft, Crankshaft, Cylinder Block, Connecting Rod, Piston, and Valves. Each part comes with a reference number that matches the exploded view. No guesswork. The Cylinder Head is on page 7 A8, along with the Breather, Flywheel, Muffler, and Governor. Need Oil Pan? Same page. But pay attention: the Engine Block & Attaching Parts span pages 5-9, A6-A10. If you order a gasket kit, those are listed on pages 9-13, A10-A14. Don’t assume a kit covers everything – check the catalog.

Fuel System Parts on Page 11

Fuel problems kill more small tractor engines than anything else. The Fuel System section lives on page 11, grid A12. You’ve got the Fuel Tank, Fuel Strainer, Carburetor, and Throttle Linkage. Also on that page: the Air Cleaner and Breather Filter. I’ve seen guys replace a carburetor when all they needed was a clean strainer. The catalog gives you exact part numbers – no aftermarket cross-reference that may or may not fit. Order from the numbers in this book.

Electrical System: Starter, Battery, Points – Pages 31-33

The Electrical System covers pages 31-33, grids C6-C8. You get the Battery (31 C6), Breaker Points (31 C6), Spark Plug (9 A10 – wait, that’s in engine section, but points are here), and Starter (33-33B C8-C12). If your 108 won’t start, start here. The manual shows exploded views of the starter assembly – you can identify the solenoid, armature, bushings. Don’t replace the whole starter when a bushing is shot. Refer to the reference numbers.

3 Reasons an OEM Parts Catalog Beats Any Third-Party List

First: accuracy. Aftermarket catalogs often merge multiple model years or leave out revisions. This catalog replaced the previous issue because Case updated parts. I trust the OEM because it came from the factory that built the machine. Second: exploded views show how parts stack. You’ll see the relationship between the Crankshaft and the Cylinder Block on page 5 A6. Third: the index. This catalog has an alphabetical index at the front and a numerical index at the back. If you know the part number, flip to the numerical index to find which page it’s on. That’s how a professional finds parts fast.

Alphabetical Index: Find Any Part in Seconds

Open the catalog, look at the first page. Alphabetical index – from Air Cleaner to Wheels. Each entry has a page and grid reference. Need the Implement Lift? Page 29 C4. PTO Clutch? Page 29 C4. Transmission? Pages 25-27 B14-C2. The index is your map. I don’t waste time flipping through 23 pages – I hit the index. That’s what the manual is built for.

Who Needs This Manual?

If you own a Case 108, you need this. DIY owners restoring a compact tractor, farmers maintaining equipment, home garage enthusiasts trying to keep a vintage machine running. The 108 is a solid tractor, but parts are getting harder to find. With this catalog, you can order exactly what you need – no returns, no hassle. Professional mechanics: keep this in the shop library. When a customer brings in a 108, you don’t waste billable time hunting part numbers. The catalog gives you the reference numbers to pull up exploded views and order correctly.

Source Authenticity: Factory Original, Not a Scan

This is an original OEM Case Parts Catalog, not a reprint. The page you see is the same one that came from Case’s own print shop. Aftermarket copies often lose detail in the exploded views or mislabel grids. I’ve been burned by third-party PDFs that were missing pages. The 23 pages here are complete – engine section, basic tractor section, decals, headlamp kit, weight box. The note on page 2 says: “It is imperative that revised Parts Book pages be inserted… Failure to do so will lead to confusion.” That’s how serious Case was. You get the genuine article.

FAQ

Does this catalog cover the Model 108 Compact Tractor only?

Yes. This A1226 catalog is specifically for the Case 108. It does not cover 110 or 118 models, though many engine parts overlap.

Are torque specifications included in the parts catalog?

No. A parts catalog lists part numbers and exploded views – it does not include service procedures or torque values. For torque specs you need the service manual. The parts catalog helps you order the right Crankshaft, Camshaft, or Cylinder Head gasket.

How do I use the grid references like “5 A6”?

Each page in the catalog is divided into a grid of letters and numbers. Look at the page – find the letter along the top (A, B, C…) and the number along the side (6, 8, 10…). Where they intersect, that’s where your part illustration lives. For example, page 5 A6 shows the Crankshaft and Camshaft.

Can I use this catalog to order parts from a Case dealer today?

Yes. The part numbers in this original OEM catalog are genuine Case numbers. Many are still available from dealers or aftermarket suppliers who cross-reference Case numbers. But always verify with your dealer – some parts have been superseded. This catalog gives you the starting point.
