TYM T723 2007 Parts Catalog – Factory Parts Breakdown for the T723

You know the drill. Tractor down, customer waiting, and you’re staring at a pile of parts that don’t match the hole in the transmission housing. Aftermarket catalogs give you a drawing that looks close, but the bolt pattern is off by 3 mm. That’s when you start wasting billable hours ordering the wrong part, then waiting for the return, then ordering again. The TYM T723 2007 Parts Catalog kills that guesswork cold. This is the exact same 269-page document the dealer uses to order genuine TYM parts. It’s printed from the factory file, not a scanned copy that lost the edge details. Every part number, every illustration, every group symbol matches what came off the assembly line in 2007.

I’ve been wrenching on tractors longer than most of you have been alive. The difference between a job that goes smooth and one that turns into a nightmare is having the right part number before you pull the first bolt. This catalog gives you that. It covers the engine (1103C-33T), the clutch, brake, steering, transmission, front axle, hydraulics, sheet metal, electrical harness, and even the weight and label groups. You get exploded views with callouts keyed to a parts list. No aftermarket re-interpretation. No “this should fit.” Just the factory’s own data.

Engine Group (1103C-33T): Identifying the Correct Parts

GROUP 01 is the engine section. It lists every gasket, piston, ring, bearing, and bolt for the 1103C-33T diesel. The catalog shows the assembly breakdown from the oil pan up to the rocker cover. If you need a cylinder head gasket, you find the part number in the illustration, cross-reference it with the table, and order. That’s it. No chasing supersessions through a parts counter. The 2007 printing date means this is the original spec – before any mid-year revisions that might have changed the part. If you’re rebuilding a T723 that’s been sitting in a field for ten years, this is the catalog you need.

One thing that catches people: the part number format. TYM uses a 10-digit number like 1733 950 001 0 for the book itself. Each part in the catalog has its own alphanumeric code. If you try to cross-reference with an aftermarket list, you’ll get mismatches because the aftermarket renumbers everything. Stick with the factory numbers. Your dealer will thank you.

What’s the Difference Between a Parts Catalog and a Service Manual?

This is a parts catalog, not a repair manual. It tells you what part goes where and how to identify it. It does not contain torque specs, disassembly procedures, or diagnostic flows. If you need to know how to pull the transmission, you want the service manual. But if you want to know the exact part number for the transmission input shaft, this is the document. For operating procedures, grab the TYM T723 Operators Manual – Factory Specs for Tractor Operation. And for the best experience with the power shuttle version, the TYM T723 Operators Manual – Factory Specs for Power Shuttle Tractor covers the specific controls. If you’re working on a different model, the TYM T603, T603NC, T603NP Parts Catalog – OEM Factory Manual follows the same format.

Match the Part Number to the Assembly

Open the catalog to any group. You’ll see a page with an exploded view on the left and a parts table on the right. The table lists the item number, the part number, the description, and the quantity. No extra clutter. The group symbols are printed at the top of each page – GROUP 03 for clutch, brake, steering, GROUP 04 for transmission. If you’re ordering a brake disc, flip to the brake section, find the illustration, note the item number, and read the part number. Write it down. Order it. Done.

I’ve seen guys order a brake assembly from an aftermarket catalog and end up with parts that are for a different TYM model because the book didn’t specify the serial number break. This catalog is specific to the T723. The part numbers are locked to that chassis. No ambiguity.

269 Pages of Verified Part Numbers

269 pages. That’s the count. Every page has a purpose. The foreword explains how to use the catalog – where to find the group symbol illustrations, how to reference the chapters, and how to order parts. The groups are numbered 00 through 09. GROUP 00 is the foreword. GROUP 01 is the engine. GROUP 02 engine accessories. GROUP 03 clutch, brake, steering. GROUP 04 transmission. GROUP 05 front axle. GROUP 06 hydraulic and 3-point link. GROUP 07 sheet metal and cab. GROUP 08 electricals and harness. GROUP 09 weights and labels. If you need a part that sits under the cab, you’re looking at GROUP 07. If it’s a wiring harness, GROUP 08. Simple.

The automotive industry relies on accurate part numbers, and the Automotive Industry Overview confirms the importance of OEM documentation. But I’ll tell you from experience: aftermarket parts catalogs are a gamble. The factory one is a sure thing. That’s why I keep this PDF on my tablet in the shop. When a customer brings in a T723 with a blown hydraulic cylinder, I pull up the catalog, find the part, and order it before I even touch the tractor. No wasted trips to the dealer.

Transmission and Brake: Where Factory Specs Matter

Transmission internals are not forgiving. One wrong bearing can wipe out the gearset. The brake section in GROUP 03 lists every disc, spring, and seal. The part numbers are the same ones the factory used when the tractor was built. If you’re replacing the brake assembly, you need the exact disc thickness and material. The catalog gives you that. The Automotive Industry Overview may talk about standardization, but in the real world, TYM uses its own specs. Don’t trust a generic cross-reference.

Short paragraph: That’s the truth.

Does this manual include torque specifications?

No. This is a parts catalog, not a service manual. Torque specs are in the TYM T723 Service Manual.

Can I use this to rebuild a transmission?

It will tell you every part number you need for the rebuild – bearings, shafts, synchros, seals, gaskets. But it won’t show you the order of assembly or the clearances. For that, you need the service manual. This catalog is your shopping list, not your recipe. You still need to know how to cook. The 2007 edition covers the transmission group (GROUP 04) with fully exploded views. If you’re ordering a transmission overhaul kit, you can pull the part numbers from this catalog and order exactly what came from the factory. That’s critical because aftermarket kits often substitute parts that change the gear mesh or the shift feel. I’ve seen it happen. The tractor comes back with a grindy second gear because the aftermarket bearing was a different thickness. Don’t be that guy.

Is the part number format consistent with current TYM parts?

Yes, but always check with your dealer for supersessions. Some parts have been updated since 2007. The catalog gives you the original part number, which the dealer can cross to the current version.

What is the part number of this book itself?

1733 950 001 0.

You need the factory part numbers to get the job done right the first time. Don’t trust a third-party list that might have been scanned from a photocopy of a photocopy. Access the Factory Manual and keep it on your phone, tablet, or computer. When you’re standing in front of a T723 with a blown engine, you’ll have the exact part number for the piston, ring, and liner. That’s the difference between a two-day job and a two-week wait.
