IMPORTANT:
Oil pump for International Harvester DT360/DT414/DT436/DT466 engines — covers the EARLY version of the IH diesel family (1971-1985). Fits IH 1066/1086/1466/1486/1566/1586 tractors and 3388/3488/3588/3688 articulated 4WDs. Gerotor type.

OEM variants: 1802666C91, 1802666C92 — same pump. These engines span 6.0L (DT360) through 7.6L (DT466) and ALL use this same pump. The #1 ordering mistake is confusing early (1802666) with late (1808832) IH/Navistar oil pumps. Match your engine serial number prefix to confirm early vs late build.

At 40-50 years old, inspect pump bore in block and drive gear teeth. Replace gasket set.

⚠️ EARLY version. Verify engine serial number — late DT466 uses 1808832.
