New Holland T8040 Parts Catalog

If you’ve ever spent an afternoon hunting for a part number that doesn’t match the bracket you’re holding, you know the frustration. This New Holland T8040 Parts Catalog — 678 pages of factory-sourced exploded views and part numbers — puts that guesswork in the rearview. I’ve been turning wrenches for 28 years, and I’ve seen more than a few jobs go sideways because somebody relied on a third-party parts list. This is the real deal: direct from New Holland, with every reference number, bolt size, and variation noted.

Radiator and Fan Shroud – Section 02-01

Section 02-01 lays out the radiator assembly and fan shroud in an exploded drawing with 57 callouts. You get part numbers for the fan itself — there are three options: an 8‑blade, 127 mm ID fan (standard performance), an 11‑blade, 711 mm fan (Mega Flow hydraulic system), and a 12‑blade variable‑pitch fan (if equipped). The pulley choices are two: 180 mm or 201 mm, each with its own shaft. Down to the M8×16 flanged bolt and the 7/16″ × 11/16″ × 1/16″ hardened washer, everything is listed. Page 1 shows the full illustration; page 2 gives the part number breakdown. If you’re replacing a fan or shroud on a T8040, you order exactly what the factory intended.

Variable Pitch Fan System – Section 02-02

This section – 02‑02 – covers the variable pitch fan system, a feature on later T8040s. It includes the compressor-to-fan hose, the variable speed fan hose, and the clamps. The exploded view on page 4 shows three main components; page 5 lists part numbers like 84140005 for the hose clamp and 84139922 for the hose itself. One note: the bolt used is a carriage bolt M8×25 class 8.8. If you’re troubleshooting a non‑variable fan, this section will tell you which parts differ from the standard setup.

Why a Factory Parts Catalog Beats Aftermarket Cross‑References

Aftermarket parts catalogs often merge design changes or leave out “If Equipped” notations. This New Holland PDF shows every variation explicitly. For example, in the fan shroud, part 84163207 (201 mm pulley) is used only on certain hydraulic system configurations. A generic cross‑reference would lump all T8040s together, and you’d end up with the wrong pulley. The factory drawing also includes supersessions – note that item 52 is a cable strap, not a bracket – information you won’t get from a third‑party list. When you’re ordering parts for a machine that costs six figures, you don’t guess.

Audience: Who Actually Uses a 678‑Page Parts Catalog?

If you own a New Holland T8040 – whether you’re a farmer, a ranch mechanic, or a dealer parts counter – this catalog is your reference. I’ve seen DIY owners try to order a radiator from a photo and end up with the wrong shroud. With this PDF, you open the exploded view, find the part number, and order the right piece. No waiting, no return shipping. The catalog covers the T8040 from 1/06 production (EU models). If you’re working on a later serial number, double‑check for updates, but 95% of the parts are identical. Pair this with the Automotive Industry Overview for broader context on agricultural equipment standards.

Three Systems You Can Cross‑Reference

Beyond the engine bay, this catalog covers the variable pitch fan system, the radiator and fan shroud, and the hydraulic system components (note the “Mega Flow” vs “Standard Flow” annotations). Each section uses the same numbering scheme: a reference number on the illustration matches a row in the parts table. You get part number, quantity, description, and any notes like “If Equipped” or “ASN Z6RW04896” (serial number break). This structure makes it possible to trace a single O‑ring or seal through multiple sections – a feature that saves hours when you’re in the field.

For a broader coverage that includes the T8010 through T8050, see the New Holland T8010 T8020 T8030 T8040 2006 Parts Catalog. Need repair procedures and torque specs? Pair this catalog with the New Holland T8010, T8020, T8030, T8040 Service Manual – 424 Pages of Factory Spe. Another option is the New Holland T8040 Parts Catalog – 627 Pages of Factory Specs which may cover a different revision.

FAQ

Does this catalog include service repair procedures like torque specs?

No, this is a parts catalog only. It lists every part and its number but does not contain step‑by‑step repair instructions or torque values.

Can I use this to identify parts for my T8040 serial number range?

Yes, but pay attention to the “ASN” (after serial number) and “BSN” (before serial number) notes in the parts table. For example, items 15 through 23 in the fan shroud section are marked “ASN Z6RW04896” – meaning those parts apply only after that serial number. If your tractor falls outside that range, you’ll need to order the earlier part. The catalog explicitly notes these breaks, which aftermarket references often ignore. Always check the production date stamp on your machine – 1/06 for EU models – and compare with the notes. If you’re unsure, call your dealer with the part number from this catalog; they can verify fitment.

Are torque specifications included in this catalog?

No. This is a parts catalog, not a service manual. For tightening values (e.g., M8×16 bolt to 28 lb‑ft), you need the factory service manual. I recommend the related model service manual linked above.

Is this a PDF format?

Yes. After purchase you get an instant access link to the full 678‑page PDF.

If you’re tired of cross‑referencing part numbers from worn‑out stickers, this catalog is your answer. Access the Factory Manual and get the exact exploded view and part number for every fastener, seal, and hose on your New Holland T8040.
