Yanmar YM220, YM220D, YM250, YM250D 2008 Parts Catalog

I’ve lost count how many times a guy walks into my shop holding a handful of unmarked bolts, saying “I need the part that goes here.” Half the time the part number is wrong because he used a third-party diagram that conflates three model years. That’s money down the drain. If you’re working on a Yanmar YM220, YM220D, YM250, YM250D 2008 Parts Catalog, you need the actual factory breakdown. Not a reprint. Not some scanned copy that clipped the edges of the bearing diagram. This is the real deal – 116 pages, OEM-issued, the same document the dealer uses when he punches your credit card.

70 Sections of Exploded Diagrams – From Cylinder Block to Roll Bar

This catalog covers 70 separate groups. Starts at the Cylinder block (section 1) and runs all the way to the roll bar (section 70). Each section has a clean exploded view with corresponding parts list. Need the Camshaft and its associated gear? That’s section 9. Crankshaft and flywheel assembly? Section 10. Valve train components? Section 5 (Cylinder head). The indexing is straightforward – you don’t waste time flipping back and forth. Engine, cooling, fuel, drivetrain, steering, hydraulics, electrics – it’s all there. The power transmission structural drawings on page 4 and 5 show the full gear train for both two-wheel and four-wheel drive versions. That alone saves you an hour of counting teeth if you’re rebuilding a transmission.

How to Use This Catalog for a Cylinder Head Overhaul

Say you’re pulling the head off a YM250. You need gaskets, bolts, maybe the fuel injection valve. This catalog doesn’t give you torque specs (that’s the service manual’s job), but it gives you the exact part numbers for every seal, O-ring, and gasket you’ll need. Section 5 has the cylinder head assembly; section 27 is the gasket kit (A) for the engine. Cross-reference the color codes on page 3 to get the right paint for the rocker cover if you care about restoration. For the Fuel system – injection pump is section 17, injection valve is 18, strainer is 19, lines are 20. You can order everything before you even break a bolt loose. That beats the hell out of finding a leaking injector and waiting three days for the wrong line to show up.

Color Codes and Part Number Suffixes – Page 3

Yanmar used ten different color codes on these tractors. Page 3 spells them out: K (metallic calm green), M (silver), P (green), Q (cream), R (red), W (frosted black), X (black), Y (yellow), Z (celva black), U (plating). If you order a fender for a YM220D without the suffix “-R” you might get a white part instead of red. The manual also includes specification code classifications for different countries (A for America/Canada, F for France, etc.). That matters when you’re sourcing hydraulic pipes or cooling water lines – European-spec parts can differ. Don’t blame me if you skip reading that page.

Is This a Service Manual or a Parts Catalog?

It’s a Parts Catalog. That means exploded diagrams, part numbers, quantities, and color codes. No step-by-step repair instructions, no torque specs, no diagnostic trees. If you need to know how to rebuild the Engine, you want the separate service manual. But if you’re ordering parts – whether it’s a camshaft bearing, a thermostat device (section 23), or a water pump (section 14) – this is the only document you should trust. Aftermarket parts catalogs often substitute superseded numbers without notifying you. This OEM copy shows the original part numbers exactly as Yanmar defined them in 2008. That’s your safety net.

Why Factory Documentation Beats Aftermarket Every Time

I’ve seen a $3,500 mistake happen because a guy used a generic parts list and ordered a fuel injection pump that was for a different governor spec. This catalog is the same one Yanmar dealers pull up on their terminals. It’s not a reprint, not a compilation from a third party. Every gear, every seal, every wiring harness section (51 and 52) is shown with the right exploded view. The lamp assemblies for YM220/220D and YM250/250D are separate sections (53 and 54) because the housing shapes differ. If you care about your tractor running right and your wallet staying intact, you don’t guess – you use factory data.

FAQ

Does this catalog include torque specifications for head bolts?

No. This is a parts catalog, not a service manual. Look for the OEM service manual for torque values.

Can I use this catalog to order parts for a YM220D that was built in 1985?

Yes. The catalog covers YM220 and YM220D tractors manufactured since April 1982, and YM250/250D since August 1986. All those are included.

What types of tires are listed in the catalog?

The catalog includes sections for ag tires (front and rear) in multiple subsections (60, 61, 63, 64), turf tires (62, 65), and even front power take-off (66). You can find the exact OEM tire part numbers and rim sizes.

How do I find the part number for the cooling water pump?

Go to section 14 – Cooling Water Pump. The exploded diagram shows the pump assembly and each component. The parts list on the facing page gives the part number, description, and quantity. That’s the number you order.
