TYM T303, T353NH 2008 Parts Catalog

If you’ve ever ordered the wrong part for a TYM tractor because some aftermarket catalog showed a generic image, you know the frustration. I’ve been there. This TYM T303, T353NH 2008 Parts Catalog is the real deal – factory printed, 213 pages, covering every group from the engine to the weight label. That means you pull the right part number the first time, not after three returns and a week of downtime. I’ve torqued enough head bolts to know that guessing costs hours. This catalog kills the guesswork.

Engine S4L and S4L2: Part Numbers You Can Trust

Group 01 is the engine section for the S4L and S4L2 diesels. You get exploded views with every gasket, piston, ring, and bearing labeled. Page 1 shows the official title and part number of this book – 13019400020. If you need a cylinder head gasket or an oil pan bolt, you find the exact factory number. No aftermarket cross-reference that might be wrong. This is the same document the dealer parts counter uses.

Transmission Group: What the Manual Covers

Group 04 is the transmission. Spindles, gears, shift forks, seals – all drawn out with callouts. The T303 and T353NH share some driveline components, but the catalog shows which parts differ. I’ve seen guys order a T303 input shaft for a T353NH and wonder why it doesn’t fit. That doesn’t happen when you use this catalog. Every part number is specific to the model and serial range. TYM T303 T353 2008 Parts Catalog is the companion to the service manual – you need both for a full rebuild.

3 Critical Groups for Your TYM Tractor

Group 05 front axle, Group 06 hydraulic 3-point link, and Group 07 sheet metal. The front axle section shows kingpin and steering arm parts. The hydraulics group covers the lift arms and cylinder seals. Sheet metal includes hood, fenders, and fuel tank brackets. If you’re piecing together a tractor from two machines, these groups save you from ordering duplicate parts. Each group has its own figure number – you flip straight to the assembly you need.

Does This Parts Catalog Include the Clutch and Brake?

Group 03 covers the clutch and brake assembly. That’s right – clutch disc, pressure plate, release bearing, brake shoes, and linkage. A lot of parts catalogs lump everything into one blurry diagram. This one separates the clutch from the brake with clear exploded views. You can identify the correct throwout bearing for your T353NH without pulling the transmission first. TYM T303 T353 Operator’s Manual for Tractors gives you the operating specs; this catalog gives you the part numbers to order.

Check the Weight Label Group Before You Order

Group 09 is the weight label section. It lists the decals and placards – safety warnings, model designations, and PTO caution labels. You might think a decal is trivial, but OSHA and local regulations care. If you’re restoring a tractor for resale or farm use, missing weight labels can fail an inspection. The catalog shows the correct part number for each label. Don’t guess. TYM T303 / T353 Parts Catalogue also includes the electrical group (Group 08) with wiring harness part numbers and switch assemblies.

Why OEM Documentation Matters

Aftermarket parts catalogs often redraw the diagrams and lose detail. I have seen a misaligned arrow point to the wrong bolt in a reprint. This manual is the original 2008 factory scan from TYM (Tong Yang Moolsan). The part numbers are the ones stamped on the OEM packaging. When you order a part using this catalog, you get the exact piece TYM designed for that tractor. That keeps your repair solid and your customer off your back. The automotive industry runs on accurate parts data – read the Automotive Industry Overview to see why standardization matters. Automotive Industry Overview is a good background read, but this catalog is the tool you need on the bench.

Frequently Asked Questions

Is this parts catalog specific to the TYM T303 and T353NH tractors?

Yes. It covers both models with separate part number callouts where they differ. No generic coverage of other TYM models. 213 pages, published 2008.

How do I find a part number if I don’t know the assembly name?

Look at the group symbols at the beginning of the catalog. Each group has a symbol (engine, transmission, etc.). Flip to the group that matches the area of the tractor where the part lives. The diagrams are arranged by physical location – engine at the front, sheet metal around the body, electricals last. If you still can’t find it, the table of contents lists every subgroup. For example, the clutch is in Group 03, not buried under transmission. The indexing is straightforward, but you have to read the part numbers exactly – one wrong digit and you get the wrong seal. I always double-check the figure number against the part number list. Takes thirty seconds and saves a week of waiting for the correct gasket.

Access the Factory Manual now and keep a copy on your tablet or printed binder. When a customer walks in with a T303 that won’t engage the PTO, you can look up the hydraulic linkage parts in Group 06 and have the order placed before lunch. That’s the difference between working smart and working twice.
