Yanmar 2TR13 Parts Catalog – 25 Pages of Factory Part Numbers

I’ve lost count of how many times I’ve watched a guy order a cylinder head gasket by engine model and end up with the wrong one because he didn’t have the parts catalog. The Yanmar 2TR13 is a solid little diesel, but its parts numbering changed around June 1976 (E/#11485). Without the OEM Yanmar 2TR13 Parts Catalog, you’re guessing which stud, plug, or O-ring goes where. That’s a wasted trip to the parts counter and a day of downtime. This 25-page factory document is how you get the right part number the first time – no aftermarket translations, no copy errors.

What the Cylinder Block Section Actually Shows

Open to page 3 and you’ll see Section Code 01 – the cylinder block. Every bolt, stud, nut, and plug has a factory part number. Item 1 is the lower block, part number 724060-01561. Item 2 is the cylinder block itself. Next to each part you get the unit quantity and a remarks column. This isn’t a generic drawing – it’s the same chart a Yanmar dealer uses. If you’re rebuilding the bottom end on a YM1300 (D), you need those head studs (item 4, 124260-01230) and the cylinder liner (item 33, 724060-01900). The catalog even calls out the spring pin size – 6D×54 for item 8. That’s the kind of detail that saves you from ordering a standard roll pin that wallows out in a week.

Gear Case Assembly – Diagram and Part Numbers

Page 5 covers the gear case. Item 1 is the gear case assembly, coupling type, part 724060-01110. The catalog lists the studs (M8×20), spring washers, and the packing for the gear case (item 7, 124060-01512). If you’re replacing the fuel pump mounting plug assembly (item 10, 724060-01520), the exploded view shows exactly how it nests with the breather plate (item 12). This is critical because the plug has an adjust feature – a generic plug won’t seal or set the timing correctly. The manual includes both the Japanese and English part names, so you can cross-reference if you buy parts domestically or import them.

How to Use This Parts Catalog on the Job

You’re not going to find torque specs or step-by-step repair procedures here – it’s a parts catalog, not a service manual. What you get is the official Yanmar index of every replaceable component for the 2TR13 engine. When you need a new injector (item 28, 124060-34050), you match the part number against the illustration. The section codes at the top (e.g., NO. 2 for cylinder block) keep you from flipping through unrelated sections. Pair this catalog with a factory service manual, and you’ve got the complete picture. For the YM1300 tractor or any equipment using the 2TR13, this is the document that eliminates the “I think this fits” nonsense.

Why OEM Beats Aftermarket Parts Catalogs

I’ve seen aftermarket parts lists that swap “hub” for “boss” and mess up the thread pitch. This is an original Yanmar publication, scanned from the factory source – no third-party editing, no lost remarks. The OCR excerpt shows the original Japanese on the left and English on the right, with the part numbers in bold. That bilingual layout is a life-saver when you’re calling a dealer in Osaka or ordering from a US distributor. For the $20 or so you pay, you avoid a $100 mistake on the wrong cylinder liner. And because it’s a PDF, you can print exactly the page you need – I keep mine in a binder on the cart.

You’ll also want to check out related catalogs for other Yanmar models: Ammann Yanmar B12 B17 Parts Catalog, Yanmar YB271, B27 1994 Parts Catalog – OEM Factory Specs, and Yanmar YB301 YB351 1991 Parts Catalog – 248 Pages OEM. These come from the same family of factory documentation, so the layout and part-numbering system are consistent. If you work on Japanese industrial engines, the Automotive Industry Overview on Wikipedia gives background on why OEM data matters, but this catalog is the real tool.

Who Needs This Manual

If you own a YM1300 (D) tractor or any equipment that runs the 2TR13 – from generators to pumps – this 25-page catalog belongs in your glovebox. Professional mechanics will use it to verify part numbers before ordering from the dealer. Home garage guys rebuilding a blown engine need it to buy the right gaskets and seals. Even a beginner can follow the exploded diagrams to identify what’s broken. There’s no “step one remove bolt” here – it’s pure parts identification. That’s what makes it valuable: you skip the trial-and-error parts ordering.

Does this catalog include torque specifications or repair procedures?

No. This is a parts catalog – it lists every component with its factory part number and section code. Torque values, clearances, and assembly steps come from a separate service manual. You need both to do the job right.

What years and serial numbers does this cover?

The manual states it covers engines produced from June 1976 (assembly number E/#11485) onward. If your 2TR13 is older than that, some parts may differ. Always verify by the engine serial number stamped on the block. The catalog lists the part numbers, but you still need to match your engine’s generation.

Don’t spend another afternoon chasing wrong parts. Access the Factory Manual and get the same exploded view that Yanmar dealers use. Your 2TR13 will thank you, and your wallet won’t take hits on returns.
