Yanmar EF200H Parts Catalog

I’ve been turning wrenches for 28 years, ASE Master since ‘96, and I’ll tell you straight: nothing wastes more time than ordering the wrong part because you trusted a blurry aftermarket diagram. You’re pulling a Yanmar EF200H engine apart, you need the exact bolt, bushing, or seal – not some generic cross-reference. This Yanmar EF200H Parts Catalog is the OEM factory book. 191 pages. No guesswork.

Cylinder Block Assembly – Fig. 1 Breakdown

Page 2 lays out the cylinder block for the 3TNV82A-NRE engine. Every plug, main bearing, head bolt, and spacer is listed with its Yamaha part number. You get the STD and undersize (U.S 0.25) and oversize (O.S 0.25) options. The table tells you which revision level (A through F) each part applies to – critical when you’re dealing with engine serial number variations. I’ve seen guys order a head gasket for the wrong revision and end up with a leak. This catalog kills that.

Gear Housing & Oil Pump – Fig. 2

Moving to page 3, the gear housing assembly includes the oil pump cover, relief valve spring, rotors, and all those o-rings that dry out after ten years. The catalog gives you the exact o-ring size (1A P-32.0, 1A S-24.0) so you don’t have to guess at the hardware store. Also lists the knock pipe (L=18) and the F.I.P pump o-ring. If your EF200H is leaking from the front cover, you need this diagram.

Mounting Flange & Oil Sump – Fig. 3

Page 4 covers the mounting flange, oil sump, and parallel pins. The flange is where the engine bolts to the tractor frame – get the wrong bolts and you’re chasing a vibration. This section shows the exact stud lengths and bolt grades. The oil sump gasket isn’t listed in the OCR snippet, but the full catalog will have it. The point is: every nut, washer, and seal has a factory part number. No aftermarket reprints here.

3 Reasons to Choose OEM Documentation

Aftermarket parts catalogs re-draw the diagrams and often transpose letters on the callouts. You end up ordering a part that looks right but doesn’t fit. The OEM Yanmar catalog uses the same numbering system the factory used when the tractor was built. You can call your dealer, read them the part number from page 3, and get the genuine part. That’s reliability. Also, the catalog includes the “effective machine no.” notes – tells you which engine serial numbers use which parts. That’s something no third-party source bothers with.

Who Needs This Manual?

DIY tractor owners rebuilding an EF200H engine after 5,000 hours. Home garage guys who want to keep their Yanmar running without paying dealer markup on parts. If you’re restoring an old EF200H and can’t find a parts source, this catalog gives you the numbers to search eBay or salvage yards. It’s also the right reference for a shop technician who needs to verify a part number in the middle of a job. I keep a copy on my tablet; beats flipping through microfiche.

Source Authenticity – OEM, Not Aftermarket

This is a direct scan of the Yanmar Agricultural Equipment Co., Ltd. publication. You can see the copyright notice on every page – Yanmar CO.,LTD. The part numbers follow the format 719802-01560, not some renumbered cross-reference. If you’re used to aftermarket catalogs that list “equivalent” parts, throw that habit away. This is the factory document. Use it to order genuine parts or to find the exact aftermarket match by cross-referencing the OEM number.

Does this catalog include engine specifications like torque values?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded diagrams. For torque specs, you need the operator or service manual.

How do I find a specific part if I don’t know the name?

Flip to the figure that matches the area you’re working on – cylinder block (Fig.1), gear housing (Fig.2), mounting flange (Fig.3). Each figure has an exploded view and a table with part numbers. The catalog is organized by engine sub-assembly. If you have the old part, match the shape to the diagram. The pages are numbered sequentially; you can also search the PDF for keywords like “bush” or “seal”.
