Bronze Lifter Bushings


 
 

The material used to make a lifter bushing plays a major factor in the longevity of a lifter. Jesel’s bronze lifter bushings are the most durable on the market. They are CNC-machined to exacting tolerances out of high-strength A-45 bronze material. It is specially formulated to work in conjunction with the DLC coated lifter bodies, as it not only provides for an excellent bearing property it also resists abrasive wear. CNC machined to exacting tolerances, Jesel bushings are available in several sizes and diameters. Jesel Keyway bushings feature an outside diameter radial groove for continuous oil flow through the lifter galley and can be installed with the keyway at the 9 or 3 o’clock position. Oil supply is metered to the lifter through an .080” feed hole and circulates internally through a .031” groove milled into the inside diameter of the bushing. The accuracy of the bushing installation is critical to the life of a keyway lifter and it is recommended to have the bushings installed by a Jesel authorized installer. Jesel bushings for Tie-Bar and Dogbone lifters are available with either a .375” through hole for oiling or non-drillled for custom oil feed location. Several styles and sizes are available to accommodate most applications.

Jesel also has the ability to custom machine bushing to your specifications. Whether it’s a custom outside diameter, length or oil feed hole, Jesel can quickly design, machine and deliver bushings.

Proper lifter to bore clearance must be maintained. Check clearance at all engine teardowns. See chart below for the correct clearances.

For aluminum blocks Jesel recommends preheating the engine block before startup.
