Hatz Diesel Engine Parts

Hatz Diesel Engine Parts

Hatz air-cooled diesel engines have a devoted following in the construction trades — they're light, reliable, and built to outlast the equipment they're bolted to. They're also famously hard to find parts for in North America. T&L Equipment stocks Hatz service parts that most U.S. dealers don't carry, and we keep cross-references current on the supersession history that makes Hatz part lookups tricky.

Why Hatz Parts Are Hard to Find Elsewhere

Hatz is a German manufacturer and its U.S. dealer network has thinned considerably. Most parts houses won't bother stocking these. T&L Equipment maintains stocking relationships with Hatz parts distributors precisely because Vegas-area contractors run a lot of European-import equipment that uses Hatz powerplants. If we don't have it on the shelf, we usually can get it within 5 business days.

Need Hatz Lookup Help?

Hatz uses both numeric and alphanumeric part numbers, and supersession histories are sometimes only documented in German manuals. Call our parts counter at (702) 798-4149 with your Hatz engine's serial number (silver plate on the engine block) and we'll cross-reference any part.
