Engine Oil Filter 1R-0739 Spin-On for Caterpillar Excavators & Industrial Engines
1R-0739 oil filter for Caterpillar 320D excavators and 3300/3400 series engines. OEM cross-reference verified. Orders from IXIN Filter.
Description
This 1R-0739 oil filter is a standard-efficiency spin-on engine oil filter engineered as a direct replacement for the Caterpillar 1R-0739, sharing the same specifications as the widely used 1R-1807 part number. It’s designed to remove contaminants and metal particles from engine oil, protecting bearings, pistons, and other critical components across CAT’s excavator and industrial engine lineup.
Product Overview
The 1R-0739 oil filter uses cellulose filter media designed to capture particulate contamination from engine oil while maintaining consistent oil flow. As a full-flow spin-on filter, it’s built for straightforward installation and reliable sealing. Each unit is dimensionally verified against OEM measurements and tested for filtration performance before shipment — not just matched by part number.
