TYM T700, T680 2007 Parts Catalog

You ever order a part off a generic exploded diagram, wait two weeks, and get something that doesn’t fit? I have. Waste of billable hours and customer patience. That’s why I keep a factory parts catalog on the bench – not some third-party reprint that guessed at the dimensions. This TYM T700, T680 2007 Parts Catalog is the original OEM document, 309 pages of factory-verified part numbers and exploded assembly drawings. TYM printed this in 2007 for their T700 and T680 tractors, and it covers everything from the CD3029TF270 engine to the cabin trim.

If you’re turning wrenches on these tractors, you need a catalog that shows you exactly which bolt, seal, or hydraulic fitting goes where. This one does. Each GROUP corresponds to a major system, and the part numbers are the same ones TYM uses at the factory. No guesswork. Let me walk through what’s inside and why this beats scrolling through a dealer’s website.

Engine Parts – Group 01 and 02

Group 01 covers the engine itself – the CD3029TF270 diesel. Pistons, rings, cylinder head gaskets, timing gears, injection pump components – all laid out in exploded views. Group 02 adds the accessories: starter, alternator, mounts, belts. If you’re rebuilding the top end, you can look up the exact part number for the valve stem seals without pulling the wrong one off a shelf. The catalog gives you a figure number and a reference to the page where the assembly is drawn. I’ve used this to order a crankshaft pulley for a T680 – matched the factory stamping, no returns.

Transmission and Clutch – Groups 03 and 04

Group 03 is the clutch system: disc, pressure plate, release bearing, pilot bearing. Group 04 is the transmission – the entire gear train, shift forks, synchronizers, seals. These tractors use a manual gearbox, and getting the wrong synchro hub can lock the whole thing up. The catalog lists each gear with its tooth count and sleeve dimensions. When you call a supplier with the OEM part number from this book, they don’t ask “are you sure?” – they ship the right item.

Brake System – Group 05

Group 05 is the brake assembly. Wet disc brakes on these tractors – you need the exact friction discs, steel plates, and return springs. The exploded view shows the order of assembly. I’ve seen a DIY guy stack the plates wrong because a cheap aftermarket diagram flipped the sequence. This catalog keeps you from making that mistake. Also lists the brake pedal linkage parts if you’re dealing with a pedal that won’t release.

Hydraulics and Three-Point Link – Groups 08 and 09

Group 08 covers the hydraulic system: pump, control valve, cylinders, lines. Group 09 is the three-point hitch – lift arms, draft links, top link, stabilizers. If a hydraulic cylinder leaks down, you can find the seal kit number without pulling the entire assembly. The catalog includes the O-ring sizes for the quick-couplers. Group 08 also lists the steering hydraulic parts – power steering cylinder and hoses.

Electrical System and Cabin – Groups 11 and 13

Group 11 is the electricals: wiring harness, switches, gauges, lights, starter relay. Group 13 is the cabin – seat, floor mats, glass, door hardware. The electrical diagrams in this catalog are not wiring schematics – they’re parts location diagrams showing where each sensor and connector lives. If you need a replacement turn signal stalk, the part number is there. Group 13 includes the cabin filter and blower motor parts for the HVAC system.

OEM Factory Documentation vs Aftermarket Catalogs

I have a stack of aftermarket parts books that are wrong. Blurry scans, part numbers that don’t cross, assemblies that were merged from different model years. This 2007 parts catalog is a direct scan of the TYM factory document. The file name says “ko-47214008309.pdf” – that’s the internal TYM part number for the book. Page 73? Not here – but the TOC shows Group 05-brake, Group 06-tire rim, Group 07-front axle. Every part number starts with the TYM prefix. Automotive Industry Overview covers the broader context, but for TYM parts, this catalog is the authority.

Related manuals that complement this one: TYM T700 Operators Manual – Factory Specs for Tractor Operation shows operating procedures. TYM T603, T603NC, T603NP Parts Catalog – OEM Factory Manual for smaller models. TYM T433, T503 2010 Parts Catalog – OEM Factory Parts Breakdown for the later generation. All factory originals, no reprints. Automotive Industry Overview – external reference if you want to see how these tractors fit into the market.

Does this catalog include torque specs for assembly?

No. It’s a parts catalog, not a service manual. It gives you part numbers and exploded views, not fastener torque values. You need the separate service manual for that.

Can I use this to rebuild the transmission?

You can use it to order the correct bearings, seals, and gears. But the step-by-step disassembly and reassembly procedures are in the service manual. This catalog shows you what the parts look like and where they go in the assembly.

Does it cover both T700 and T680 models?

Yes. The front cover says Model: T700, and inside it references the T680. The chassis parts list and engine sections include both. The T680 has a different wheelbase, so check the group 06 tire rim section and group 07 front axle for variations.

How do I find a part number if I don’t know the group?

Use the table of contents. Each group is labeled (Group 01-engine, etc.). If you have the machine serial number, start with the engine group for engine parts, transmission for drivetrain, brake for brakes. The catalog also has a figure index on the first pages that lists assembly illustrations by group and figure number.

I’ve been turning wrenches since before some of you were born. I don’t waste time on guesses. When a customer brings in a T700 with a blown brake seal, I grab this catalog. I look up the friction disc part number. I call the dealer. I get the right part in two days. No returns. No makeshift parts. That’s what you get when you Access the Factory Manual – the actual OEM document that TYM printed for their dealers in 2007. 309 pages, every group, every part number. If you work on these tractors, this is the reference you need on your bench.
