Tong Yang Moolsan T254NC 2014 Parts Catalog

You need the right part number the first time. On a tractor like the Tong Yang Moolsan T254NC 2014 Parts Catalog, guessing gets you a box of wrong bolts, a week of return shipping, and a pissed-off customer. I’ve seen guys spend three hours cross-referencing aftermarket lists that don’t match the actual castings. This catalog kills that. It’s the original factory print from Tong Yang Moolsan – 102 pages, published 2014, with every screw, seal, and sub-assembly called out by OEM number.

Page 1 lists the book’s own part number (11139120030) so you know it’s genuine. The rest is pure parts data: FIG 101 through FIG 901 covering engine, chassis, and everything in between. No generic diagrams. No “compatible with” labels. You get the exact exploded views and part numbers Tong Yang uses on the assembly line.

What You Get With 102 Pages of OEM Parts Data

Nine major figure groups. FIG 101 starts the cylinder block. FIG 201 moves to the transmission housing. FIG 301, 302 – hydraulics. FIG 401 is the front axle. FIG 501 covers steering. FIG 601 dives into the PTO clutch assembly. FIG 701 is the electrical system. FIG 801 handles sheet metal. FIG 901 wraps up with accessories. Each figure has a numbered callout, a description column, and quantity. You see “BOLT, FLANGE – 11111008100 – QTY 4” and you know exactly what to order.

FIG 101 Through FIG 901: How the Manual Organizes Parts

The manual uses a group symbol system. On page 3 of the catalog, the instructions explain: find the symbol illustration (like a cylinder icon for engine), go to the relevant figure, then look up the part. The figures are grouped logically but not by system name – you need the symbol key. That’s fine because the index on page 4 shows each figure number and its section. For example, FIG 601 is labeled “P1 CYLINDER CASE” with a note that the date 2014 indicates the last revision. That level of specificity means you’re not deciphering a third-party translator’s guess.

Why Aftermarket Parts Lists Fail on the T254NC

I’ve seen aftermarket catalogs that list a “hydraulic filter” without telling you it’s LH or RH, left/right orientation, or whether it’s part of an ASSY or a SUB. This OEM document uses abbreviations: ASSY means you can break it apart, COMP means it’s a sealed unit. LH, RH, FR, RR – all defined on page 5. No ambiguity. If you order an aftermarket part using a generic cross-reference, you risk getting the wrong thread pitch or the wrong-length bolt that bottoms out before it torques. This catalog gives you the Tong Yang Moolsan part number, and that’s what you give your dealer.

Audience Fit: Who Needs This Catalog on the Bench

If you own a T254NC – whether it’s a 2014 model or a later serial number starting H00001 – this catalog is your parts bible. DIY mechanics rebuilding a blown motor need to know which main bearing set to order. Workshop owners stocking shelves need the exact quantities per assembly. Even a dealer parts counter should have this PDF open instead of scrolling an outdated price list. The serial number range starts at H00001, but Tong Yang uses these catalogs across multiple years – the 2014 edition is the reference for all T254NC tractors built to that spec. Pair it with the related Tong Yang Moolsan T293HST 2009 Parts Catalog if you service the HST variant, or the Tong Yang Moolsan T254NH 2014 Parts Catalog for the NH model. Those use different front axles and PTO configurations. For older machines, the Massey-Harris-Ferguson FF 30 GS 1957 Parts Catalog | OEM Fastener Guide shows how OEM fastener documentation has been done right for decades.

Source Validity: Printed in 2014 by Tong Yang Moolsan

This is not a scan of a photocopy. It’s the original PDF from Tong Yang Moolsan Co., Ltd., with the factory stamp on page 2 – KTB network B/D 12F, Yeoksam-dong, Seoul. The part number of the book, 11139120030, is printed right on the cover. Every figure, every callout line, every quantity – it’s exactly what the factory uses to assemble the tractor. The automotive industry in general benefits from that kind of traceability; see the Automotive Industry Overview for how standards matter. On this specific tractor, the catalog supersedes all earlier editions – so if you have a 2012 version, throw it out. This one is current.

Does This Catalog Include Engine Part Numbers?

Yes. The engine section starts at FIG 101 (cylinder case) and runs through FIG 116 (cylinder head and valve train). Every gasket, piston ring, and oil seal is listed with a Tong Yang Moolsan part number and quantity. No torque specs – that’s the service manual’s job – but you get the components you need to order.

How to Order Parts Using This Catalog

Find the figure for your assembly (e.g., FIG 401 for front axle). Read the callout numbers. Write down the part number, description, and quantity. Call your dealer with the tractor model T254NC and serial number. That’s it. One phone call, one order, no returns.

Can this catalog help me identify bolts I already took out?

No. This catalog lists factory installed components. If you have a bolt that corroded or got swapped, you need to measure thread pitch, length, and grade. The catalog won’t tell you that. It tells you what originally went there.

How do I know this is the correct catalog for my tractor’s serial number?

The factory says the T254NC serial number starts at H00001. The catalog covers all serial numbers from that range up to any changes in later revisions. If your tractor is a 2014 model or earlier, this catalog applies. For later models, cross-check the book part number 11139120030 with your dealer. The manual itself states on page 3 that specifications may change without notice, so always verify with the spare parts department if you have an unusual serial number. That said, in my experience, Tong Yang updated these books every few years and the 2014 edition is the most common reference for T254NC tractors sold in North America. If you’re ordering parts for a very late production unit, you might need the 2016 revision. But for 90% of you, this is what you need.

Don’t waste time on generic parts lists. Access the Factory Manual and keep it on your tablet or laptop right next to the tractor. Every time you order a part, open the PDF, find the figure, read the callout. Your parts bin will thank you.
