Yanmar YM241D Parts Catalog – OEM Factory Specs

If you’ve ever ordered a part for a Yanmar tractor from a aftermarket catalog and got the wrong size piston ring or a transmission seal that didn’t fit, you know the pain. I’ve been wrenching for 28 years – ASE Master, running a 6-bay shop in San Antonio – and I’ve seen guys lose half a day because some reprint catalog had a mislabeled part number. That’s why I only use factory documentation when I’m pulling parts for a rebuild. The Yanmar YM241D Parts Catalog (Pub. No. K060E1293) is the real deal: 144 pages of OEM part breakdowns, no shortcuts, no generic illustrations.

This isn’t a service manual. It’s a parts catalog – but without it, you’re flying blind on part numbers. You need the correct cylinder head gasket for the ZTR20A-YP engine? You find it in the Engine section, page 9. Need the front axle bracket for the YM241D model? That’s in Chassis Parts, separate from the two-wheel-drive YM241. The catalog gives you exploded views with each part called out by figure and page. No flipping through three different books hoping the number matches.

144 Pages of Parts Breakdown

Page count matters. A cheap reprint might stuff everything into 60 pages and leave out half the figures. This factory catalog uses all 144 pages to cover the engine assembly from cylinder block to gasket kit, the chassis including the transmission and front axle, plus the wiring diagram. Every section starts with a structural drawing – power transmission, travelling transmission, front driving sectional views – so you see where each part lives before you order it.

Engine Parts: Cylinder Block to Gasket Kit

The engine section alone runs 19 chapters. You’ve got the cylinder block (page 1), gear housing, cylinder head, air cleaner with pre-cleaner, governor, camshaft, main bearing & crankshaft, piston & connecting rod, lubricating oil system, cooling water system, fuel injection system, fuel oil system, oil pump system, governor system, electric starting system, starter (12V-1.3kW type S114-14E), AC generator (12V-10A type LT15-52), thermostat device, and the full gasket kit. That’s every part Yamnar intended for the ZTR20A-YP engine. Want the oil pump drive gear? It’s in Chapter 13. Need the pre-cleaner element for the air cleaner? Chapter 4. The drawings are factory-original, not redrawn by some intern.

Transmission Sectional Views – What You Get

Transmission work on these old Yanmars is common – seals leak, bearings wear. The catalog gives you three separate travelling transmission sectional views: one for the YM241, one for the YM241D (the 4WD model), and a combined view for both. You also get a dedicated front driving sectional view for the YM241D. That means you can identify the exact input shaft, shift fork, or differential part number without guessing which variant you have. I’ve seen shops order a transmission gasket for the 2WD model and then wonder why it doesn’t seal on the 4WD. This catalog kills that mistake.

Does This Catalog Cover the Wiring Diagram?

It does — page ix shows the full wiring diagram. While this isn’t a wiring repair manual (you’ll want the factory service manual for that), the diagram helps you identify the correct harness connectors, starter relay, and alternator parts. If you’re chasing a no-start and need the starter (12V-1.3kW), the part number is right there in Chapter 16. Pair this with the service manual for torque specs and procedures, and you’ve got a complete system.

Why OEM Documentation Beats Aftermarket Reprints

Aftermarket parts catalogs for older Yanmar tractors are notorious for reusing figures from different models or leaving out the “D” variant parts entirely. I’ve seen a reprint catalog that showed the YM241 front axle bracket under both models — wrong. The YM241D has a different front axle bracket, and the factory catalog calls that out clearly in Chapter 24 (separate from Chapter 23 for YM241). If you want to avoid ordering the wrong tie rod end or hydraulic pump seal, you need the source document that Yanmar’s own parts department uses. That’s this catalog.

Get the Right Part Numbers – Every Time

The catalog’s table of contents is laid out with figure numbers and page references for each component group. You don’t scroll through a blurry scan. Each part is shown in an exploded view with a reference number that corresponds to the parts list. For the engine gasket kit (Chapter 19), all gaskets are listed with individual part numbers — head gasket, intake manifold gasket, exhaust gasket, etc. You can order exactly what you need, not a universal kit that’s missing the valve cover gasket.

For context, the Yanmar YM241D Parts Catalog Pub. No. K060E1293 is the same document you’re looking at right now. If you work on other Yanmar equipment, check the Ammann Yanmar B12 B17 Parts Catalog or the Yanmar YB271, B27 1994 Parts Catalog – OEM Factory Specs. And if you want to understand how OEM parts catalogs differ from generic automotive documentation, see the Automotive Industry Overview. You can also read more about the Automotive Industry Overview for background on factory spec standards. But for this tractor, you’ve got the exact manual you need.

Does this parts catalog include torque specifications or repair procedures?

No. This is strictly a parts catalog – exploded views, part numbers, and quantities. It does not contain service procedures or torque values. You’ll need the Yanmar service manual for repair steps.

Can I use this catalog to order parts for my YM241D tractor?

Yes. That’s exactly what it’s for. Every engine, transmission, chassis, and electrical component is listed with factory part numbers. The sectional drawings show the 4WD model specifically, so you can identify the front axle and driveline parts. Just match the figure reference numbers to the parts list, then order from any Yanmar dealer using those numbers.

Does this catalog also cover the YM241 (2WD) model?

It covers both the YM241 and YM241D in the same binding. Sections are clearly marked – for example, the front axle bracket has separate chapters for each model. The power transmission drawings also differentiate the two. You won’t confuse parts between the two models if you pay attention to the headings.

How many pages is the catalog?

144 pages, all factory original content. No condensed reprint.
