Technical Specifications: Caterpillar 116-3254 Piston Oil Jet TubeThe Caterpillar 116-3254 Piston Oil Jet Tube is a critical engine lubrication and thermal management component. It precisely directs targeted streams of high-pressure engine oil toward the undersides of the piston domes, transferring intense heat away from the pistons to prevent thermal deformation, optimize combustion stability, and reduce the risk of structural failure.
