TYM T430, T450 Parts Catalog – Factory OEM Parts Breakdown

If you’ve ever ordered a part for your TYM tractor and got the wrong one because the aftermarket catalog showed the wrong drawing or omitted the serial number break, you know what I’m talking about. That’s money thrown away and time you don’t get back. This TYM T430, T450 Parts Catalog is the factory document – not a reprint, not a scan of a scan. It’s the same 270-page PDF that TYM’s own parts counters use. Every figure, every key number, every part number came straight from the engineering drawings. No guesswork.

TYM T430, T450 Parts Catalog – What It Covers

This catalog covers the full machine – engine and chassis. Page 2 of the manual states: “This catalogue deals with engine and chassis.” It doesn’t waste space on theory. You get exploded-view figures for every major assembly: radiator (FIG 023), fuel system, steering, transmission, axles, hydraulics, electrical, and more. The table of contents lists over 100 figures. Each figure groups parts with key numbers that cross-reference to a numerical index at the back. That index is your fastest route to the right part number – if you know the part number, you jump straight to the figure. If you only know the assembly, you start with the group symbol illustration on the first pages.

Radiator Assembly (FIG 023): Identifying the Right Part

Take the radiator group as an example. FIG 023 shows the radiator, fan, shroud, hoses, and mounting hardware. Each item gets a key number, a part number, a description, and quantity. The description includes abbreviations like LH (left hand) and ASSY (assembly). If a part number ends with an alphabet code, that tells you the material or paint color – DG for black, BR for bright red, MS for metallic silver. That kind of detail keeps you from ordering a black bolt when you needed a bright red one. The figure also shows a date code (month/year) so you know when the drawing was last updated. No surprises.

Does This Parts Catalog Cover the Engine and Chassis?

Yes – the engine group is included in detail, as is the entire chassis. The catalog groups parts by functional location. For the engine you’ll find cylinder head, pistons, crankshaft, oil pump, injection pump, alternator, starter, etc. For the chassis: front axle, rear axle, transmission, PTO, steering, brakes, wheels, hydraulic system, electrical system, and sheet metal. If you need the service manual with repair procedures and torque specs, get that separately – this catalog is strictly for part identification and ordering. Pair it with the service manual and you’ve got the full picture. Check out the TYM T430, T450, T390, T400 Service Manual – Factory OEM Specs for the repair side.

3 Reasons to Use the Factory Numerical Index

First, it’s the fastest way to find a part when you already have the part number. Second, the index tells you which figure and key number that part appears on – so you can see the assembly context. Third, it’s the only way to verify supersessions; the catalog includes the latest part numbers. Don’t trust aftermarket cross-reference websites that guess. This is the actual TYM data.

Ordering Parts: Avoid the Wrong Part Number

Page 2 of the catalog gives a clear ordering procedure: give the dealer your tractor model T430 or T450, the serial number (starting W050000 for T430), the part number, description, and quantity. If you skip the serial number, you might get the wrong version of an assembly. The catalog also warns: “When replacing parts, please use original spare parts to be sure of the performance and the longer life of the product.” I’ve seen cheap aftermarket bolts snap in the field – don’t be that guy.

Check the Date Code on the Figure Page

Each figure page shows a month/year code at the top right – for example, 07/03 under FIG 023. That tells you when that section was last revised. If your tractor is newer than that date, double-check if TYM issued a later update. The catalog itself may be updated without notice, so having the latest PDF is critical. This file is the original factory release, not a later reprint with altered numbers.

Is this a repair manual or just a parts list?

It’s a parts catalog – exploded views and part numbers only, no repair procedures.

Can I use this to order parts for a T433 model?

No. This catalog is specific to T430 and T450. Other models like T433 use different part numbers and figures. Get the correct catalog for your model.

How do I find a specific bolt for the steering assembly?

Locate the steering group figure (around FIG 200 series) in the catalog. The figure shows each bolt with a key number. Write down the part number next to that key number. Then cross-check the numerical index to confirm the part number hasn’t been superseded. If the bolt is listed as “M10x25” in the description, that’s the thread size and length – but always use the part number to order, because the bolt grade (like 10.9) may be critical for safety. TYM doesn’t always list grade in the description. The part number guarantees you get the correct fastener.

What does the part number suffix like ‘DG’ mean?

DG means black paint. BR is bright red, SW summer white, PB pure black, TY tangerine yellow. It’s the finish or color, not the material.

Look, I’ve been turning wrenches for 28 years. I’ve seen guys order a radiator for a T430 and get the wrong one because they used an aftermarket catalog that merged the T430 and T440 parts. This factory catalog eliminates that mess. 270 pages, all original figures, no missing pages. If you work on TYM tractors, you need this on your tablet or laptop.
