Part of the New Holland Parts Manuals.
What's inside: the New Holland factory illustrated parts catalogue for the TB100 4-cylinder ag tractor, build 12/02 onward, 1,232 pages. Every figure is an exploded drawing with its own Ref / Part Number / Qty / Description table, so you match a callout to the number you order. Be clear on the split before you buy: pages 5-300 are the TB100 tractor itself, laid out the CNH way - front and rear axles, steering and brakes, the tandem hydraulic gear pump and lift, the emissionized engine with block, pistons and rods, radiator and water pump, fuel and injection, transmission and PTO, wiring harnesses and instruments, seat, hood and decals. Pages 301-1216 are something else: nine complete FARM LOADER parts catalogues bundled behind the tractor - 32LA, 33LA, 46LB Ag Loader, 52LA, 7210-Series Quick Attach, 7310, 7312, 7314 and 7511 - shared across the TB, TL, TN and TS tractor series. If your TB100 wears one of those, that half of the book is worth as much as the first. If it does not, it is a tractor parts catalogue with a large loader library attached. This is a parts-identification book: no repair procedures, no torque values, no troubleshooting.

New Holland TB100 Common Problems This Manual Covers
Rear brakes fading or pulling to one side, and you need discs, actuators or linkage parts without splitting the tractor twice.
Pull up the Brakes And Brake Controls breakdown in the wheels and axles section before you crack the housing. It shows every disc, plate, seal and linkage piece with quantities, so you order the complete stack in one hit and only open the axle once.
Manual Section: Wheels, Axles, Steering and Brakes - Brakes And Brake Controls p. 15Coolant weeping from the water pump or a crusty radiator on a 20 plus year old tractor, and parts counters keep asking for numbers you don't have.
The engine and cooling section has separate exploded views for the Radiator And Related Parts and the Water Pump And Related Parts on the emissionized engine, including the pump gaskets and hardware, so you walk in with exact part numbers instead of a description.
Manual Section: Engine, Cooling and Fuel System - Water Pump And Related PartsThree point hitch drops under load or the lift shaft bushings are sloppy, and you need to know what wears inside the cover before ordering.
Use the hydraulics section: the Cover & Related Parts and Lift Shaft & Related Parts diagrams show the shaft, bushings, seals and cover hardware piece by piece, and the Tandem Hydraulic Gear Pump breakdown covers the pump end if pressure is the real issue.
Manual Section: Hydraulics, Lift and Three-Point Linkage - Lift Shaft & Related Parts p. 58Loader joystick on a 7210 or 7310 series quick attach is leaking or sticking, and single lever control valves came in half a dozen part number variants.
The 7210 series loader section breaks out each Single Lever Control Valve by its specific assembly number, with the mounting parts listed separately, so you can match your exact valve variant instead of gambling on a lookalike spool assembly.
Manual Section: 7210-Series Quick Attach Farm Loaders - Single Lever Control Valve p. 518Frequently Asked Questions
Is this a repair manual with procedures and torque specs?
No. This is the illustrated parts list only - exploded drawings with Ref / Part Number / Qty / Description tables. There are no repair procedures, no torque values, no troubleshooting charts. If you need to actually split the tractor or set clutch adjustment, the separate TB110/TB100/TB120 Repair Manual is the book for that. This catalogue is what you open when you need the correct part number before ordering.
Why is the file so big when the TB100 is a fairly simple tractor?
Because most of the book is not the tractor. Only the front portion covers the TB100 itself. The rest - about 73 percent - is nine complete New Holland loader parts catalogues bundled behind it: 32LA, 33LA, 46LB Ag, 52LA, the 7210 series quick attach, 7310, 7312, 7314 and 7511. If your TB100 wears one of those loaders, that is a genuine bonus. If it runs bare, that back section is dead weight you can ignore.
My TB100 has a loader on it. How do I know if it's covered here?
Check the loader model plate, usually on the mainframe crossmember or a boom arm. If it reads 32LA, 33LA, 46LB, 52LA, 7210, 7310, 7312, 7314 or 7511, you are covered down to mounting kits, control valves, cylinders and hydraulic lines. These loader books were shared across the TB, TL, TN and TS series, so the same section also serves a TL90 or TN75 wearing the same loader. p. 301
Does it cover both 2WD and 4WD front ends?
Yes. The wheels, axles, steering and brakes section carries separate breakdowns for the 2WD front wheels and the 4WD front wheels, plus the 4WD front axle and transfer box. That matters because almost nothing interchanges between the two front ends - kingpins, hubs, seals and bearings are all different part numbers, and guessing from a 2WD diagram on a 4WD tractor is how you end up with the wrong seal on the bench.
Will this work for a North American / Mexican built TB100 wiring harness?
Yes, and this is one place the catalogue earns its keep. The electrical section lists the main front harness for the 4/6 cylinder tractors in both the standard version and the NHNA/Mexico version, plus the separate NHNA/Mexico front lights harness. Harnesses are the classic wrong-order part because they look identical in a photo listing - the diagrams here let you match connectors and routing to your actual tractor before you spend the money.
