Isuzu 8973026880 Oil Pump Drive Gear

The 8973026880 gear functions as the oil pump drive gear (Power Take-Off idler) within the Isuzu 4J-series engine valve train. It transfers rotational motion from the camshaft to the oil pump assembly, maintaining consistent lubrication pressure across engine operating ranges. Manufactured to OEM specifications with 25 teeth (Z=25), this component is constructed from case-hardened alloy steel to withstand high cyclic loading and wear in heavy-duty industrial applications. It serves as a direct replacement for Isuzu part numbers 8-97302-688-0 and 897302-6880. Cross-referenced as GEAR; IDLER PTO Z=25 in Mitsubishi Fuso/Isuzu joint catalog systems.
