TYM T431, T451 2007 Parts Catalog – OEM Factory Parts Breakdown

If you’ve ever ordered a part for a TYM tractor and ended up with the wrong component because the aftermarket listing was off by one digit, you know the headache. This TYM T431, T451 2007 Parts Catalog is the exact same binder the dealer uses. 371 pages of factory exploded diagrams, OEM part numbers, and assembly breakdowns. No guesswork, no cross-referencing three different websites to confirm a seal size. You get the part number straight from the source.

Engine Group Coverage – V2203B and V2203M

The catalog splits the engine into two sections: GROUP-01 ENGINE V2203B and GROUP-01 ENGINE V2203M. These are the diesel engines fitted to the T431 and T451. Each section shows the cylinder head, block, timing gears, oil pump, and all internal components with individual part numbers. If you need a piston ring set or a head gasket, you look up the engine variant, find the illustration, and grab the number. No aftermarket guesswork.

Engine accessories are covered in GROUP-02. That includes the alternator, starter, injection pump, water pump, and fuel filters. The illustrations are clear enough that you can identify a bracket or a bolt without holding the old part in your hand. For a tractor that’s been sitting in a field for five years, that alone saves a trip to the dealer.

Get the Right Brake and Transmission Parts

GROUP-05 brake and GROUP-04 transmission are two sections you’ll use when the clutch pedal starts feeling wrong or the tractor won’t stop straight. The brake group shows the discs, plates, shafts, and return springs with exact OEM numbers. The transmission group covers the gearbox housing, gears, shift forks, and PTO drive. If you’re tearing down a T431 to do a clutch or a bearing, you need the exploded view from this catalog to order the correct snap ring and shim set. Aftermarket catalogs often skip the shims – this one doesn’t.

Clutch and Hydraulic Systems: What You Get

GROUP-03 clutch has the pressure plate, disc, release bearing, and flywheel. GROUP-08 hydraulic covers the pump, control valve, lift cylinder, and lines. For a tractor that uses implements, the hydraulic section is critical – the part numbers for seals and O-rings are listed per assembly. No aftermarket cross-reference needed. Same goes for GROUP-09 3P link (three-point hitch) and GROUP-07 front axle. If you need a tie rod end or a steering cylinder, you find it there.

Wheels and tires are in GROUP-06. GROUP-10 sheet metal covers hoods, fenders, and grilles. GROUP-11 electricals includes the wiring harness sections, switches, and lighting – though keep in mind this is a parts catalog, not a wiring diagram manual. For electrical diagnostics, you’d want the service manual. But for ordering a headlight assembly or a switch, this is the list.

What Does a Parts Catalog Do for a DIY Mechanic?

A service manual tells you how to take it apart and put it back together. A parts catalog tells you what to order before you start. If you’re rebuilding a T451 engine, you open GROUP-01 ENGINE V2203M, find the piston and ring illustration, and write down the part numbers. Then you order them. No running to the dealer mid-job because the aftermarket piston doesn’t match. This manual saves time not by making the job easier, but by making the parts procurement phase accurate. For a home garage guy who doesn’t have a parts counter on speed dial, that’s real value.

The catalog also includes the chassis section (T431-T451-chassis) and two separate engine parts lists (V2203B-TYM1 and V2203M). Those lists give you the full exploded view with callouts. Page numbers aren’t always sequential in a parts catalog – you navigate by group number and figure number. Once you get the hang of it, you can find any part in under two minutes.

371 Pages of Exploded Diagrams and Part Numbers

That’s 371 pages of factory data, printed in 2007. The document is a PDF scan of the original printed catalog – not a reprint from some third-party that guessed at the part numbers. The part number for the book itself is 1291 912 003 0. That’s the OEM identifier. The catalog covers both the T431 and T451 models. It’s organized by group, and each group begins with a divider page showing the group number and title. For example, GROUP-04 transmission starts with a page that lists all the transmission assemblies, then each sub-assembly has its own figure.

If you’re working on a TYM tractor and need to order anything from a fuel cap to a brake shoe, this is the document you want open on your tablet next to the workbench. For the broader context of why OEM documentation matters, see Automotive Industry Overview. Aftermarket parts catalogs often combine multiple models into one confusing list – this catalog keeps the T431 and T451 separate where the parts differ, and combines them when the parts are shared.

Frequently Asked Questions

Can I use this parts catalog to rebuild the engine on my T431?

No. This is a parts identification book, not a service manual. It tells you what parts to order, not how to install them.

How do I find the correct part number for my T451 transmission input shaft?

Open the transmission group (GROUP-04). Find the figure number for the input shaft assembly. Each part in the drawing has a reference number that links to a table with the OEM part number, description, and quantity. The drawing also shows the shaft orientation so you can verify you’re looking at the right part. Aftermarket catalogs often skip the orientation callouts – this one doesn’t.

Does this manual cover the V2203M engine that came in my T431?

Yes. GROUP-01 ENGINE V2203M is a dedicated section. There is also GROUP-01 ENGINE V2203B for the other engine variant. Check your tractor’s engine plate before ordering.

Why should I buy an OEM parts catalog instead of an aftermarket one?

Aftermarket parts catalogs frequently combine multiple model years into one diagram, omit sub-assembly details, and list wrong part numbers because they rely on cross-references from suppliers. This catalog was printed by TYM in 2007 – the same year the T431/T451 tractors were manufactured. The part numbers match what the factory installed on the assembly line. If you order a part by the number in this book, it will fit. That’s worth the price of the access.

If you’re tired of playing parts roulette with aftermarket listings, get the factory data. Access the Factory Manual and start ordering parts that actually fit.
