This Tech Tip is a number we publish regarding industrial engines. While most have focused on Perkins, Deutz, Wisconsin and other industrial engines, this one focuses on a new engine brand for us, Isuzu industrial engines. Many engine pros have complained about the difficulty they have in ordering Isuzu industrial engine parts. This Tech Tip, similar to one on how to find the Perkins engine serial number (Tech Tip #20 : Perkins Serial Numbers), shows you where to find the engine serial number on an Isuzu industrial engine.
Ordering parts for Isuzu industrial engines can be difficult because everything is based on the Isuzu industrial engine’s serial number. But Foley can help. We have listed below the location of the all-important serial number. Please note that this list DOES NOT include information about the on-the-road Isuzu truck engines. Foley Engines only supports Isuzu industrial engines used in off-road applications.
