It’s also compatible with combines, windrowers, sprayers, and cotton equipment that use these proven diesel engines.

Made to Last

Farm equipment oil pumps take a beating from dust, temperature extremes, and long operating hours. This pump is built with quality materials and precision manufacturing to handle the punishment. The robust housing and internal components are designed to maintain proper oil flow and pressure even under the heavy loads and extended duty cycles common in agricultural applications.

Installation Notes

Installing an oil pump requires draining the oil and removing the oil pan, so plan on a complete oil change while you’re at it. This is typically an engine-out job or requires significant disassembly, so it’s often best handled by someone familiar with diesel engines. Prime the pump thoroughly before first startup by pre-filling the oil galleries and turning the engine over several times with the ignition disabled to prevent dry-start damage.
