Tong Yang Mulsan T603NC, T603NP 2008 Parts Catalog

If you’re elbow-deep in a Tong Yang Mulsan T603NC, T603NP 2008 Parts Catalog tractor and need the right part number, guessing costs time and money. I’ve seen guys order a whole hydraulic pump assembly when all they needed was a seal because they used a third-party cross-reference that had the wrong diagram. This is the original factory document – 461 pages, no reprints, no aftermarket garbage. It covers both the T603NC and T603NP models with the engine (C2,2T) and chassis groups split clearly. You get the same part numbers the dealer pulls up.

That foreword on page 3 tells you exactly how to find a part: tractor model, serial number, part number, description, quantity. Don’t skip that step. The serial number range (W050000 and up) is printed right there. If you order without it, you’re gambling. The catalog even shows the part number for the catalog itself – 1993 950 001 0 – so you know it’s official.

Tong Yang Mulsan T603NC, T603NP 2008 Parts Catalog: What’s Inside

The table of contents splits into ten groups. Group 00 is the foreword – how to read the exploded views, what the abbreviations mean (ASSY, COMP, SUB, SET), and the date of each section. Then you get Group 01 – engine (C2,2T) – with all the internal parts: cylinder block, pistons, crankshaft, the works. Group 02 covers engine accessories: water pump, fuel injection, alternator bracket. Group 03 is clutch, brake, and steering – all one section because on these tractors the steering shares the same housing as the clutch. Group 04 is the transmission – the gearbox and PTO. Group 05 is the front axle. Group 06 is the hydraulic system and 3-point link. Group 07 is sheet metal and cab. Group 08 is electricals and harness – wiring diagrams? No, this is a parts catalog, not a wiring manual. But it shows every connector, relay, and harness clip by part number. Group 09 is weight and label – decals and counterweights.

Each group has figure numbers and section pages. For example, the radiator shows up as P1 FIG 023 in the foreword sample. That’s how you navigate: find the figure, then the part number.

Engine Group (C2,2T) – Page 132 Details

Page 132 starts the detailed engine breakdown after the general index. You’ll find the cylinder head and valve train exploded view. The part numbers are listed in a table: column for figure number, reference number, part number, description, quantity, and remarks. Need a piston ring set? It’s in there. The catalog also notes LH and RH locations for parts like engine mounts. If you’re rebuilding the C2-2T engine, you need this page open on the bench – otherwise you’ll end up with a piston for the wrong bore size.

Does This Catalog Cover the Hydraulic System?

Yes. Group 06 – hydraulic and 3P link – has its own figure numbers. It includes the pump, control valve, lift cylinder, and the linkage for the three-point hitch. The part numbers are specific to the T603NP and T603NC, so if you have a T603NP with a different hydraulic valve block, the serial number will steer you to the right sub-assembly. Don’t assume the hydraulic parts are the same between models – I’ve seen a T603NC use a different relief valve spring than the T603NP. The catalog catches that.

3 Groups That Eliminate Guesswork

Group 03 (clutch, brake, steering) is one of the most useful when you’re chasing a clutch pedal issue. The exploded view shows the release bearing, fork, and the brake master cylinder – all in the same figure. Group 08 (electricals) saves you from buying the wrong alternator because you can match the part number to the harness connector. Group 05 (front axle) includes the steering knuckle and tie rod ends – critical for a tractor that sees field work. These three groups cover most of the wear items that fail on a 2008-era Tong Yang Mulsan tractor.

Stick with OEM Documentation – Why Aftermarket Fails

Aftermarket parts catalogs often use generic drawings and cross-reference tables that miss model-year splits. The original Tong Yang Mulsan catalog has the exact part numbers from the factory, including the Korean-headquarters part numbering system (e.g., 16001032000 for an air cleaner assembly). The foreword even warns that the information may be modified without prior notice – that’s why you need the 2008 version A, printed 2008/08. Any later revision could supersede this, but for a 2008 tractor, this is the right one. Don’t trust a third-party PDF that claims to be “compatible” – it’s not. Stick with this official print.

Is this a repair manual or a parts catalog?

Parts catalog only – part numbers, exploded views, no repair procedures.

Can I use this to order parts for a T603NP with serial number W050000?

Yes. The manual includes a section on how to locate parts by tractor serial number. On page 3 of the foreword, it shows the format: tractor model, serial number, part number, description, quantity. You need that serial number to match the correct chassis variant. The catalog covers both T603NC and T603NP, but there are differences in the engine group and chassis parts list version 1. If you skip verifying the serial number, you risk ordering a part that doesn’t fit. I’ve seen it happen. The factory even includes a note about using original spare parts for performance and longer life. Don’t ignore that.

That’s the difference between a parts catalog and a repair manual.
