HATZ 4M42 2008 Parts Catalog – 40 Pages of OEM Spare Part Numbers

Description

If you’ve ever tried ordering a part for a HATZ 4M42 off a generic cross-reference list and ended up with the wrong gasket or filter, you know the frustration. That waste of time and money stops here. The HATZ 4M42 2008 Parts Catalog is the original factory document – 40 pages of exact part numbers, exploded views, and maintenance specs. No aftermarket shortcuts, no guessing what fits.

Engine Identification: 4M42.10 and the EPA Tier IV Interim Variant

Page 2 of this catalog shows the engine designation format. Your engine serial number tells you which variant you have – for example, 1431008123456 breaks down to a 4M42.10. That .10 suffix identifies the EPA Tier IV Interim configuration, which has specific emission-control parts. Those parts don’t cross to older 4M42 models. This catalog lists the correct part numbers for that exact build. Without it, you risk ordering a piston ring set meant for a different emissions package.

What Parts Are Listed in This 40-Page Catalog?

Everything from the cylinder head down to the oil pan drain plug. The catalog is arranged by engine system groups – injection, cooling, lubrication, starting system, and more. Each group has a exploded diagram with numbered callouts that reference the part numbers below. You get the HATZ factory part number, description, and quantity per engine. For example, the oil filter housing assembly includes the filter cartridge, O-rings, and bypass valve – each with its own part number. That level of detail is what saves you from buying a seal kit that doesn’t include the right-sized O-ring.

Maintenance Schedules and Oil Specs Straight from HATZ

Page 3 of the catalog reproduces the official HATZ maintenance chart. It lists service intervals at 500 and 1,000 hours, with oil change recommendations based on ambient temperature. You see SAE 5W-30, 5W-40, 10W-30, 10W-40, and 15W-40 grades – all with temperature ranges in both Fahrenheit and Celsius. The chart also shows valve clearance check intervals (0.1 mm or 0.004″) and the required tool numbers (M00, M34, etc.). If you ignore these specs, you’ll either over-maintain or miss a critical inspection. The catalog gives you the factory reference, not some third-party summary.

Page 2 Warning: Why You Use Original HATZ Parts

That page isn’t filler. HATZ states directly: “The installation of inappropriate spare parts may cause problems. We cannot accept any liability for damage or consequential damage resulting therefrom.” This isn’t a marketing pitch – it’s a liability statement backed by years of field data. Aftermarket parts may look the same but differ in metallurgy or tolerance. I’ve seen aftermarket injectors fail within 50 hours on these engines. The catalog gives you the original HATZ part number so you can order the real thing from any HATZ dealer. The page count is 40 pages because every part is listed with its genuine number, not condensed into a generic list.

3 Reasons a Parts Catalog Beats a Generic Cross-Reference

First, you get the exact supersession history – HATZ updates part numbers, and this 2008 edition captures them. Second, the exploded-view diagrams show how parts fit together, which helps identify hidden components like dowel pins and snap rings. Third, the multi-language format (German, English, French, Spanish, Italian) means you can hand this to any parts supplier and they’ll read the same number. Generic catalogs often drop the diagrams and merge multiple engine families into one confusing table. This is the original, 40-page document that HATZ printed for its dealers.

Source Validity – What Makes This Different?

This is a direct scan of the HATZ factory-printed catalog, not a re-keyed or translated version. The PDF includes the original page numbers, copyright, and part numbers as they appear in HATZ’s system. Aftermarket parts catalogs are notorious for copying old data and missing supersessions. I’ve personally seen an aftermarket source list a part number that was discontinued in 2005 – for a 2008 engine. That doesn’t happen here. For more background on how diesel engine parts are standardized, you can reference this Wikipedia article on diesel engines. Or go straight to the source: this Wikipedia article on diesel engines provides a good overview of common fuel-system layouts.

FAQ

Does this catalog include torque specs?

No, this is a parts catalog; torque specs are in the service manual.

What languages are the parts lists in?

The catalog includes German, English, French, Spanish, and Italian. Page 1 shows the title in all five languages, and every page lists part descriptions in these languages. This is helpful for international shops ordering parts from HATZ directly. The part numbers are numeric and consistent across languages, so you can order from any HATZ dealer worldwide. The multi-language format also reduces errors when communicating with suppliers who speak different languages. If you work with a distributor that prefers German, you have that option. For a 40-page document, this level of localization is rare and shows HATZ’s commitment to global service.
