When you’ve got an Onan generator powering critical operations on your farm or worksite, keeping that engine oil clean isn’t something you can put off. Dirty oil loaded with metal particles and combustion byproducts will turn your reliable generator into an expensive repair job fast. This Baldwin oil filter does the heavy lifting to catch all that grime before it can damage expensive internal components.

- Compact 2 19/32 inch length with 4 5/8 inch diameter that fits tight engine compartments
- Quality filter media that captures contaminants while maintaining proper oil flow through the system
- Flange gasket design with 5 3/16 inch outer dimension for secure, leak-free mounting

Built for Real Work
This filter is designed for Onan engines that power generators used across farms, construction sites, and commercial operations. Whether your generator is running grain dryers during harvest, powering irrigation systems, or keeping the lights on during outages, this filter protects engines that need to run reliably when you count on them most.
Made to Last
Baldwin has been making filters for decades, and they know what it takes to protect an engine under demanding conditions. The sturdy construction handles pressure fluctuations and temperature swings that come with generator operation, while the attached gasket ensures a secure seal that won’t leak under pressure.
Installation Notes
Apply a thin coat of clean oil to the gasket before installation, then hand-tighten only 3/4 turn after the gasket contacts the mounting surface. Over-tightening can damage the gasket and cause leaks. Change this filter with every oil change to keep your Onan running clean and strong.
