TYM T554ST, T554NC, T454ST, T454NC 2014 Parts Catalog

If you have ever ordered a bolt for a TYM tractor and got the wrong thread pitch, you already know why this catalog matters. That guesswork costs you time and sometimes a trip to the dealer. This is the TYM T554ST, T554NC, T454ST, T454NC 2014 Parts Catalog – the same 141-page document the factory shipped to dealers. It is not a reprint. It is not a third-party compilation. It is the original PDF from TYM, with the part number 1746 950 001 0 printed on page 1.

Every figure in this catalog corresponds to an exploded view of an assembly – engine, chassis, hydraulics, electrical, steering, brakes, and more. You look up the figure, find the part number, and order exactly what you need. No cross-referencing outdated aftermarket databases. The catalog covers the T554ST, T554NC, T454ST, and T454NC models, all in one document.

Parts Breakdown by Figure Number

The Table of Contents lists figures from FIG 101A through FIG 902. Each figure is a dedicated exploded diagram of a specific section, like the cooling fan (FIG 023) on page 3, or the air cleaner assembly you see on page 2 (part number 17461039100). You don’t scroll through a hundred pages to find a fuel filter. You go to FIG 401 or 402. The catalog uses a group illustration system – a symbol on the corner of each figure tells you which part of the tractor you’re in. That symbol matches the ones printed on the machine itself in many cases.

Every figure lists the part number, description (with abbreviations like ASSY, COMP, LH, RH), the quantity needed per tractor, and sometimes a consumption frequency class to help you decide what to keep in stock. Page 4 explains exactly how to read the columns – spec, quantity, options marked with AR (as required).

Audience Fit: Who Needs This Parts Catalog

This is for anyone who owns or services a TYM T554, T454, or their NC/ST variants. It is also for a parts manager at a dealership who needs to pull the correct number for a clutch disc or a hydraulic seal. A home garage enthusiast working on his own compact utility tractor will find this catalog more useful than a generic parts list because the drawings are model-specific. You see the exact washer and its position. Count the number of bolts in the diagram – order that many. No surprises.

If you are a mechanic like me, you use this catalog to verify you have the right part before you start the job. That saves you a return trip. Pair it with the TYM T603, T603NC, T603NP Parts Catalog – OEM Factory Manual if you service the larger chassis, or the TYM T433, T503 2010 Parts Catalog – OEM Factory Parts Breakdown for older models. The TYM lineup shares some hardware, but always check the specific figure.

Source Validity: OEM vs Aftermarket

The catalog is printed and distributed by TYM’s parts division. The OCR excerpt on page 2 says “This supersedes all our editions.” That means this 2014 version is the current release. Aftermarket websites often grab a scanned copy, blur a figure, and sell it as their own. What you get here is the original PDF with the cover page showing “TM 동양물산 기계사업부” (TYM’s manufacturing division). The page numbers match the factory printing. There is no watermark over the drawings. That matters when you are trying to read a part number on a split-screen view.

For a broader context of how these manuals fit into the industry, read the Automotive Industry Overview and the Automotive Industry Overview for background on OEM standards. But the short version: factory data is the only data you can stake a repair on.

How to Use the Parts Catalog – From Group Indication to Ordering

The catalog has a clear workflow explained on pages 3 and 4. First, locate the group symbol illustration – those little pictures in the corner of each page. They show whether you are in the engine section or the chassis section. Then find the figure number for the assembly you need, for example, FIG 201 for the engine cylinder head. The section name is printed at the top. The section page number tells you where it is. Then read down the part list: description, spec (like M10x1.25 bolt), quantity, and part number. When you order, give your dealer the tractor model, serial number (starting with H00001 on page 2), the part number, description, and quantity. One more thing – the catalog notes that AR means “as requested quantity.” Do not order 10 if you need 1.

Each figure also has a “Date” field showing when the page was last updated – 2014/04 for this edition. That keeps you from using an obsolete drawing.

7 Systems Covered in This Parts Catalog

Based on the figure numbering blocks, the catalog is organized into at least seven major systems. There is a block for engine (FIG 101A through 122B), clutch and transmission (FIG 201-208), rear axle and brakes (FIG 301-309), front axle and steering (FIG 401-418), hydraulics and three-point hitch (FIG 501-507), electrical and instrumentation (FIG 601-613), and the cab or rollover protection structure (FIG 701-719 plus FIG 801-902). Each block contains multiple figure numbers for sub-assemblies – for example, FIG 704A and 704B cover two views of the cab. That level of detail is why you do not lose a weekend hunting for a part.

Related tractor families share common figures. Check out the TYM T303, T353 2008 Parts Catalog – OEM Factory Manual if you work on the smaller chassis. The numbering convention is consistent across the TYM line.

FAQ – Parts Catalog for TYM T554ST, T554NC, T454ST, T454NC

Does this catalog include torque specifications for assembly?

No. This is a parts catalog, not a service manual. It lists part numbers, not torque values. You need the factory service repair manual for torque specs and overhaul procedures.

Can I use this catalog to order parts for a 2015 TYM T554?

The catalog was printed in 2014. TYM may have superseded some parts with newer numbers after 2015. Cross-check the part number with your dealer, but the diagrams remain accurate for the T554 architecture.

How many pages are in this PDF?

141 pages. The file is the original scan with full-color exploded views. Each figure is on a separate page or spread.

What models are covered – do I need separate catalogs for the T454ST and T454NC?

All four variants (T554ST, T554NC, T454ST, T454NC) are included in this single 2014 Parts Catalog. The figures call out differences where applicable, with option symbols next to parts that vary by model.

That PDF sits on my shop tablet right now. It saves me from calling the dealer every time I replace a seal on a TYM hydraulic pump. You need that level of accuracy on your next repair. Access the Factory Manual, print the page for the assembly you are working on, and keep it in a binder near your toolbox.
