New Holland T8040 Parts Catalog – 627 Pages of Factory Part Numbers

If you’re ordering parts for a New Holland T8040, the aftermarket catalogs will get you close – close enough to order the wrong fan shroud seal or miss a superseded part number. I’ve seen it happen in my shop. A guy brings in a T8040 with a leaky variable pitch fan system, he’s got a generic parts list from some website, and the compressor bracket bolt pattern is wrong. That costs you half a day and a second shipping charge. What you need is the original factory Parts Catalog – the same one the dealer parts counter uses. This document is 627 pages of exploded-view diagrams, OEM part numbers, and quantity callouts. Nothing else gets you a correct hose clamp part number like 1348264C1 for the 3/8″ ID hose on the radiator drain system.

Let me show you what’s inside and why it matters on your bench.

627 Pages of Factory Part Numbers

You don’t buy a parts catalog for the reading – you buy it to find the exact piece of metal or rubber that goes back in the hole. This one covers the entire T8040 from the radiator fan shroud to the final drive. Every section starts with a reference number on the diagram, then a table listing part number, description, and quantity. Page 2 of the manual shows the Radiator and Fan Shroud assembly: 87445032 for an 8-blade fan, 87331959 for the shroud itself, and 87615750 for the variable pitch fan (if your tractor has BSN Z7RW05000). That level of specificity is what keeps you from ordering the wrong viscous drive.

Need the variable pitch fan compressor? The catalog section 02-02 lists it as 87620726, with the correct hose clamps 87589798 and the special carriage bolts 308761 for T8010 through T8040 models. Without this catalog, you’re guessing which M8 x 25 bolt has the short neck.

Radiator and Fan Shroud: The Details Matter

Section 02-01 is a classic example of why you need the factory book. There are 55 line items in that assembly alone. Seals? You get six different ones: 87438140, 87307220, 87305705, 87386756, 426352A1, 87305704, and 87391827. They look the same on an aftermarket diagram, but the part numbers and dimensions are different. The catalog tells you which seal goes where. It also gives you the bolt torque specs? Actually no – this is a parts catalog, not a service manual. But it cross-references to the service manual for assemblies like the radiator assembly (see figure 02-02). That’s why I pair this catalog with the NEW HOLLAND T8010 T8020 T8030 T8040 Service Manual”>NEW HOLLAND T8010 T8020 T8030 T8040 Service Manual on my shelf.

Variable Pitch Fan System: What the Manual Covers

Section 02-02 is only six parts, but each one is critical. The compressor (87620726) is an expensive piece – order the wrong one and you’re stuck with a T8050 part that doesn’t fit your T8040 firewall bracket. The catalog separates the compressor mounting hardware by BSN and by model: T8010–T8040 get carriage bolts and flange nuts, T8050 gets hex flange bolts and lock nuts. That distinction prevents a stripped thread and a comeback. The New Holland T8010 T8020 T8030 T8040 2006 Parts Catalog”>New Holland T8010 T8020 T8030 T8040 2006 Parts Catalog covers the same timeframe if you need cross-referencing across the series.

Why You Need the OEM Parts Catalog

Aftermarket databases copy the original drawings in third-generation photocopies. The resolution drops, the callout numbers get rearranged, and someone transposes a digit. I’ve seen a 87445032 turn into 87445023 in a reprint. That 8-blade fan becomes a paperweight. This catalog is a direct scan of the factory print – the same one used in Turin when they built these tractors. The quality is good enough to read the part numbers even on the small font items like the 87016603 washer (7/16″ x 11/16″ x 1/16″, hardened). You won’t find that washer in a generic hardware store bin.

The New Holland T8040 Tractor Parts Catalog”>New Holland T8040 Tractor Parts Catalog is the specific manual for your machine. It covers the EU build from 1/06 onward. If you’ve got a T8040 with a BSN prefix you can match the part numbers directly. For background on how these tractors fit into the broader Automotive Industry Overview”>automotive industry manufacturing ecosystem, that’s interesting history – but for your workbench, you just need the right part number. Automotive Industry Overview”>Automotive industry standards on fastener grades matter here too: the catalog calls out M8 x 16 8.8 bolts and Cl 10 nuts. Those specs are factory-verified.

What This Catalog Won’t Do

This is a parts catalog, not a service manual. It won’t tell you how to replace the viscous fan drive or what the torque spec is for the radiator bracket bolts. For that, you need the corresponding service manual. What it will do is get you the correct part number so you can order the seal, hose, or bracket without the 30% restocking fee. It also helps you identify superseded parts when you’re at the dealer counter. I keep the PDF on a tablet in my tool box – 627 pages searchable by part number. That beats flipping through a paper catalog with my greasy hands.

Can I use this catalog to find torque specs for the T8040?

No. This is a parts catalog only – no torque values, no repair steps. You need the service manual for that.

Why are there six different seals listed for the radiator shroud area? Which one do I need?

Each seal has a unique application: the channel seal (87438139) goes between the shroud and the core, the upper and lower seals (87305705, 87386756) mount to the side brackets, and 426352A1 seals the top corner joint. Without the factory diagram, you’ll likely buy the wrong one because the aftermarket catalogs lump them under “seal kit.” The exploded view on page 2–3 shows each seal’s physical position – match the reference number to the callout, and you’ll get the exact part. I’ve used this catalog to identify a single 87391827 seal that a customer swore was “just a generic rubber strip.” It’s not – it’s a formed seal with a specific lip profile. Order the right one, and the fan shroud doesn’t rattle.

You don’t need to guess which fan blade or viscous drive fits your T8040. The factory parts catalog puts the whole assembly in front of you with part numbers that match the dealer’s system. Stop burning time and money on return shipping. Access the Factory Manual from AutoRepairManuals and get the OEM part data your tractor deserves.
