Product Introduction of the 1R0739 Oil Filter
The 1R0739 engine oil filter is a full-flow spin-on filter developed for compatible heavy-duty diesel engines and construction machinery. It removes metal particles, carbon deposits, sludge, and other contaminants from circulating engine oil.
Clean and stable oil flow helps protect bearings, crankshafts, turbochargers, and other important engine components from premature wear. The durable steel housing, secure threaded connection, and oil-resistant sealing gasket allow the filter to perform reliably under pressure, vibration, and demanding working conditions.
The product is also commonly searched as 1R-0739, 1R 0739, or 1R0739 oil filter.

Product Case: 1R0739 Filter for Construction Equipment
A construction fleet operating wheel loaders and excavators found heavy carbon deposits and fine metallic particles in the engine oil during scheduled maintenance. Continuous operation in dusty conditions increased the risk of internal engine wear.
The maintenance team replaced the used filters with compatible 1R0739 oil filters. After replacement, the engines maintained cleaner oil circulation and more stable lubrication during long working shifts. Regular filter inspection and timely replacement also helped reduce contaminant-related wear and supported more reliable equipment operation.
