Tong Yang T233, T273 2007 Parts Catalog – Factory Specs for Tractor Parts

If you have ever ordered a part for a tractor and ended up with the wrong bracket, seal, or bolt because the parts diagram was from a third-party reprint, you understand the frustration. I have seen guys pull a head off a Tong Yang T233 only to find the replacement gasket set doesn’t match because the aftermarket catalog used a generic illustration. That costs time, money, and sometimes a cylinder head. This is the factory Tong Yang T233, T273 2007 Parts Catalog — 249 pages of OEM exploded views, part numbers, and assembly groupings straight from the manufacturer. No guesswork, no generic clip art. You see the actual bracket, the exact bolt, and the correct quantity.

Engine Coverage: GROUP 01-engine(S3L2-S3L)

The first major section in this catalog covers the engine — specifically the S3L2 and S3L variants used in the T233 and T273. You get over 40 figure references (FIG 101 through FIG 145) that break down every component from the cylinder block to the injection pump. Each figure includes a callout with the Tong Yang part number, description, and quantity. For example, if you need a piston ring set for a T273, you find the figure, cross the description, and order the exact factory number — not a “universal” set that leaves you one ring short. This is the same catalog a dealer parts counter uses.

Chassis Groups: Clutch, Brake, Steering, and More

After the engine section, the catalog moves to chassis groups: GROUP 03-clutch,brake,steering, GROUP 04-Transmission, GROUP 05-front axle, GROUP 06-hydraulic & 3p link, GROUP 07-sheet metal & cab, and GROUP 08-electrical. Each group has its own set of figures (e.g., FIG 201–207 for clutch/brake/steering). If you are rebuilding a steering box on a T233, you pull up that group, find the figure, and identify every seal, shim, and bearing by factory number. No need to call the dealer and hope the kid behind the counter guesses right.

7 Systems Covered – Full Group Breakdown

The catalog is organized into nine numbered groups plus foreword. The engine group alone covers 45 figures. The hydraulic group includes FIG 601–614. The electrical group covers FIG 801–805. Having the complete set means you can restore a tractor from frame up without ever wondering if a part number is correct. I have used parts catalogs like this to source $2 seals that saved a $2,000 hydrostatic pump. You do that when you have the right figure in front of you.

How to Use This Parts Catalog – Factory Instructions

The manual includes a section titled “How to use parts catalogue” (page 4 of the PDF) that explains the group indication symbols, figure numbers, and how to decode the description abbreviations. For example: “ASSY” means an assembly that can be broken into individual parts; “COMP” is a non-serviceable assembly. “LH” is left hand, “RH” is right hand. This matters when you order a tie rod end that says RH and you accidentally order the LH side. The catalog shows exactly which figure and column to read. Also, the front matter lists the part number of the catalog itself (1315 912 003 0) so you can order a replacement if you spill coffee on it. That is how precise this document is.

OEM Original vs. Aftermarket Catalogs – No Comparison

I have seen aftermarket parts catalogs that merge two different model years into one drawing, or skip a critical hardware row because the publisher didn’t have the original film. This is the original 2007 Tong Yang file, scanned from the factory release. The part numbers match what Tong Yang stamped on the metal. When you call a dealer and give them a number from this catalog, they say “that’s the one.” Aftermarket copies often use different numbering schemes or omit the supersession notes. Stick with the factory file.

Who Needs This Catalog and Why

If you own a Tong Yang T233 or T273 tractor — or maintain a fleet — this catalog is your parts bible. I have used OEM parts catalogs to locate a single bushing that kept an entire 3-point hitch from slopping around. Without the factory figure, you end up pulling three different bushings from a bin and hoping one fits. With this catalog, you order the right one the first time. It is also useful for a shop that does restoration work: the exploded views show correct assembly order, which helps when you have a box of parts and no idea how they stack together.

For ordering parts, the manual gives the exact procedure: tractor model, serial number, part number, description, quantity. Hand that to your dealer and the transaction takes two minutes. I have seen parts counters hold up a whole job because the paperwork didn’t have the serial number. This catalog saves that headache.

Frequently Asked Questions

Does this catalog include torque specifications for assembly?

No. This is a parts catalog, not a service manual. It does not list torque specs. You need the separate service manual for bolt tightening values. What it does give you is the exact factory part number for every nut, bolt, and gasket on the engine and chassis.

Can I use this catalog to identify parts for a T273HST model?

Yes. The catalog covers both T233 and T273, including the HST (hydrostatic) variants. The engine section is specifically labeled S3L2-S3L, and the chassis groups apply to both models. Check the figure notes for model-specific callouts.

How many pages is the catalog and what year was it published?

249 pages. Published in 2007 by Tong Yang Moolsan Co., Ltd. The part number printed inside the cover is 1315 912 003 0.

Is this a scanned copy or a digital PDF?

It is a digital PDF reproduction of the original factory printed catalog. The pages are clear, the figures are readable, and the text is searchable for part numbers and descriptions.

If you are tired of playing “guess the part number” and want to get your Tong Yang T233 or T273 back in the field with the right pieces, get the factory document. Access the Factory Manual from AutoRepairManuals and keep it on your tablet or printed at the workbench. It will pay for itself the first time you order a $5 retaining ring instead of an entire hub assembly.
