Bushings are common components used in industrial machinery, electric motors, and many automotive systems, including differentials, transmissions, and engines. Sometimes used in conjunction with bearings, bushings are a “removable cylindrical liner for an opening (as of a mechanical part) that is used to limit the size of the opening, resist abrasion, or serve as a guide,” according to Merriam Webster. Bronze is a durable bushing material, providing years of service that sometimes lasts longer than the equipment in which it is installed. Depending on the component or machine in which the bronze bushing is installed, lubrication is a simple task.
Access the bushing, if it is still installed on the component. To properly lubricate bronze bushings, it is necessary to access the inside of the bushing, which requires the removal of any axle or accessory that the bushing is designed to hold. If the bushing is to be removed, a sliding hammer is needed to loosen the bushing and a properly sized bushing driver is required to reinstall the bushing.
Apply lubricating grease. Liberally coat the inside of the bushing with white lithium or graphite grease. Lithium Graphite Greases are high quality lubricants often used in automotive racing applications.
Reassemble the component. When reassembling the component, wipe off excess grease. Use a free finger to wipe off any excess grease from the bushing when reassembling the component.
