New Holland W170B Parts Catalog – OEM Factory Parts Breakdown

You’ve got a New Holland W170B wheel loader down in the yard. The hydraulic hose blew, and you need a replacement. You check the old hose, guess the length, and order from a third-party supplier. It arrives two inches short. Now you wait another week, the machine sits, and the job slips. That is the exact problem this factory Parts Catalog solves. It gives you the precise OEM part number, the right size, the correct variant, and the ordering codes. No eyeballing. No guessing. Fact sheet.

This is the official New Holland W170B Parts Catalog, 2nd Edition, published February 2009. It runs 882 pages and covers the Tier III version of the W170B for the European market. The document is printed under New Holland copyright, print number 6040435100. It is a genuine factory document, not a scanned copy from a third-party seller. The catalog is available in English, French, Italian, and German, so you can work in the language you trust.

What the 882 Pages Cover

The catalog is structured around the parts ordering process. Section one starts with Instructions for Ordering Spare Parts on page 3, followed by Ordering Rules on page 4. These are critical. They tell you how to read the exploded diagrams, how to reference the version of your machine, and what information your dealer needs to process the order correctly. Skip these pages and you risk ordering parts for the wrong sub-model. After that, page 22 gives Abbreviations – useful when you see codes like “HYD” or “ELEC” on the diagrams. Page 23 has a Conversion Chart (Inch-mm). Do not assume the bolt is metric just because the loader came from Europe. The Identification and Version List on pages 25-27 is where you match your machine’s serial number to the correct parts group. The Maintenance Parts section begins on page 29, listing filters, belts, and fluids. The Number Index on page 33 lets you look up a part number directly and see which diagram page it appears on.

Ordering Parts Without This Catalog Is a Gamble

I have seen too many technicians order a hydraulic pump for a W170B only to get the wrong displacement because they didn’t verify the version code. The catalog includes multiple versions – the W170B EU Tier III is one, but there may be running changes within that. The version list tells you which revision of the boom arms, the cab, or the transmission your serial number corresponds to. If you skip that step, you are rolling dice. The ordering rules on page 4 also explain how dealer part numbers relate to the factory codes. If you use this catalog, you walk into the parts counter with the exact item number. No back-and-forth. No “I think it’s this one.”

Factory OEM Documentation vs. Aftermarket Parts Catalogs

Aftermarket parts catalogs often use generic part numbers or re-index numbers that don’t match the New Holland system. That is a recipe for getting a part that looks right but has a different bolt pattern or a different thread pitch. This manual is the original factory print, copyrighted by New Holland. The diagrams are the same ones the dealer uses. The Automotive Industry Overview confirms that OEM-sourced data eliminates the variation that aftermarket rebuilders introduce. The 2nd Edition from 2009 incorporates all updates up to that date. If New Holland released a service bulletin that changed a part number, this catalog reflects it.

Who Needs This Parts Catalog

This is for equipment owners who do their own maintenance, fleet managers who have a W170B in the shop, and independent mechanics who work on construction loaders. If you are a home garage enthusiast working on a W170B that you bought at auction, this catalog is the foundation of your parts ordering. You can also use it to identify components that are no longer available and find superseded part numbers. The exploded diagrams show every bolt, washer, and seal. You will know exactly what you need before you pull the wrench.

3 Reasons to Use the Identification and Version List

First, the W170B has multiple cab types – open ROPS, enclosed AC, and low-profile. Each uses different glass, seals, and wiring. The version list on page 25 tells you which group your machine belongs to. Second, the engine variant (Tier III vs later aftertreatment) changes the fuel system parts. The version list matches the engine serial number range to the correct injector and pump. Third, the transmission version affects the torque converter and clutch discs. Ordering the wrong clutch pack means pulling the transmission twice.

Frequently Asked Questions

Is this a service manual or a parts catalog?

This is a parts catalog, not a service manual. It does not contain torque specs or repair procedures. It lists every factory part with exploded diagrams and order numbers.

How do I use the number index on page 33?

If you have a part number in hand – either from a previous order or from the old part itself – look it up in the Number Index. The index gives the page number where that part appears in the exploded view. Then go to that page, find the part in the diagram, and verify the description and quantity. This is the fastest way to confirm compatibility.

Can I use this catalog to order parts from a New Holland dealer?

Yes. The catalog follows the same numbering system the dealer uses. Provide the part number from these pages, and the dealer can cross-reference it. Keep the version list handy – the dealer will ask for the serial number.

Does this manual cover all W170B models, including older machines?

This 2nd Edition covers the W170B EU Tier III models built up to 2009. Earlier non-Tier III machines may have different part numbers for the engine and emissions components. For those, check the version list on page 25-27. If your serial number falls outside the ranges listed, you need the earlier edition catalog. We also carry related documents like the Ford New Holland 853 1993 Parts Catalog, the Ford New Holland 568 1991 Parts Catalog, and the Ford New Holland 1915 Tractor 1993 Parts Catalog – Section: Supplement for older equipment.

When you have the factory part number in your hand, you stop the cycle of ordering wrong parts. The automotive industry (see Automotive Industry Overview) runs on precision, and this catalog gives you that precision for your W170B. Access the Factory Manual from AutoRepairManuals and get the exact part numbers you need. Don’t let a two-inch misalignment cost you a week of downtime.
