Yanmar YM14 Parts Catalog

If you’re tracking down a part number for a Yanmar YM14 and you’ve been burned by aftermarket reprints that swap numbers or leave out revision levels, I get it. I’ve sent back three wrong head gaskets in one week because some online list didn’t match the factory stamp. This Parts Catalog is the OEM document – 118 pages of exploded diagrams, reference codes, and genuine Yanmar part numbers. No third-party interpretation. No guessing which bolt goes where.

Cylinder Block Assembly: Part Numbers and Reference Codes

The first figure in this catalog shows the cylinder block assembly with every stud, plug, seal washer, and bearing housing called out by part number. You see things like STUD, CYL. HEAD 105430-01200 and the exact quantity: two per block. There’s a column for revision levels – (A), (B), (C) – so if your machine has a later casting you know which part to order. Page 2 lays out the block components from the main cylinder block (705546-01561) down to the decompression wire support (105546-03900). If you’ve ever ordered a rear cover gasket (105430-01490) and got a mis-cut aftermarket version, you’ll appreciate having the factory reference.

Side Cover Components: What the 118 Pages Cover

Figure 2 covers the side cover assembly – the cover itself (705546-01501-Z), filler cap (105546-01750), breather assembly (105546-03010), and the governor lever (705546-61501). Each part has a line number, part number, description, and quantity for every revision level. The catalog uses a coded system for availability – letters like (F), (E), (D) indicate which manufacturing period the part applies to. That matters when you’re dealing with a YM14 that’s been through a rebuild. You won’t find torque specs here – this is a parts catalog, not a service manual – but you will get the exact fastener dimensions, like BOLT M8X20 PLATED 26116-080202, so you can order the right hardware.

Does This Manual Replace a Service Manual?

No. This is strictly a parts identification document. It gives you exploded views, part numbers, and quantities. For torque sequences, adjustment specs, or repair procedures, you need the factory service manual for the Yanmar YM14. But if you’re rebuilding the engine and need every seal, O-ring, and bolt listed by OEM number, this catalog is what you bring to the parts counter. Use it alongside the service manual and you won’t be chasing wrong parts.

3 Reasons to Choose OEM Yanmar Documentation

One: revision codes. Aftermarket reprints often flatten all design changes into one list, so you get a single part number for the cylinder head gasket when there were actually two different types (105546-01330 and a later version). This catalog shows you both. Two: quality marks. Factory drawings include details like “PLATED” on bolts and “SEAL WASHER” on plugs – things a generic parts list ignores. Three: you get the full 118 pages. No condensed version that cuts the governor linkage section.

Using This Parts Catalog on a Real Job

Say you’re replacing the oil pump rotor on a YM14. Open to the side cover section. You see ROTOR ASSY, LUB. OIL part number 104500-32150. Also listed: the O-ring (103338-32570), the oil pump cover (103338-32070), and the mounting bolts (M6X12 plated, 26106-060122). Order the whole set from one page. No cross-referencing between three different websites. The catalog also includes check valve and shelter plate for the breather – parts you might overlook if you’re going off memory.

Parts Catalog vs Aftermarket Reprint: The Difference

Aftermarket parts lists often copy the diagrams but leave out the revision data or substitute their own part numbers. This is a direct scan of the Yanmar publication. The page layout matches what you’d get from a Yanmar dealer, including the copyright notice: (C)Copy Rights YANMAR CO.,LTD and YANMAR AGRICULTURAL EQUIPMENT CO.,LTD. You get the full 118 pages of exploded views, part numbers, and reference tables. If you want to confirm a part number against the stamp on your old part, this is the document to use.

FAQ

Can I use this catalog to find torque specs?

No. This is a parts catalog, not a service manual. Torque values are not listed.

How do I identify the correct part number from the diagram?

Each figure has a table with line numbers and reference letters (A, B, C, etc.) that correspond to the drawing. Match the revision level of your engine – found on the block stamp – to the column labeled with that letter.

Is this the same as the Yanmar factory manuals?

Yes, this is a direct reproduction of the OEM Yanmar parts catalog for the YM14 model. It includes all original part numbers, diagrams, and revision codes exactly as Yanmar printed them. Aftermarket versions often omit the revision columns or use generic descriptions like “gasket” instead of specifying the correct part number for your production period. That can lead to ordering a part that doesn’t fit, especially on engines that had running design changes. This catalog preserves every detail, including the quantity per assembly and the specific fastener plating requirements.

What if a part is discontinued?

The catalog lists the OEM part number. You can then cross-reference that number with Yanmar’s current availability or look for NOS (new old stock) suppliers.

Don’t waste time guessing which bolt or gasket you need. Access the Factory Manual for the Yanmar YM14 and get the exact OEM part numbers straight from Yanmar.
