Description

There’s nothing worse than hearing your engine start to knock or finding metal shavings in your oil—signs that contaminated oil has been circulating where it shouldn’t. This Baldwin B39 filter catches dirt, metal particles, and combustion byproducts before they can damage expensive engine components. Whether you’re running an old GMC farm truck or maintaining equipment with AMC or International engines, clean oil means longer engine life and fewer headaches down the road.

What You’re Getting

Anti-drainback valve that keeps oil in the system when you shut down, giving you instant lubrication on startup
4 3/8 inch length with 3 11/16 inch diameter provides adequate filtration capacity for these engine sizes
13/16 – 16 thread size matches original equipment specifications for secure mounting
Quality Baldwin construction that handles temperature swings and engine vibration without failing
Spin-on design makes oil changes quick and straightforward

Built for Real Farm Work

This filter works across AMC, General Motors automotive applications, GMC trucks, and International engines that you’ll find in farm trucks, older tractors, and various pieces of equipment around the operation. These are the workhorses that haul feed, pull trailers, and keep your operation moving when the newer equipment is busy in the field.

Made to Last

Baldwin has been making filters since before most of us were born, and they understand what it takes to protect engines in demanding conditions. The filter media traps contaminants while maintaining steady oil flow, and the sturdy construction handles the pressure spikes and heat cycles these engines create without breaking down.

Installation Notes

This is a standard spin-on filter, so changing it is as simple as unscrewing the old one and threading on the new. Apply a thin coat of clean oil to the gasket before installation, then hand-tighten plus 3/4 turn once the gasket contacts the mounting surface. Don’t over-tighten—it just makes the next change harder.
