PAI 045088 Injector Rocker Cam Follower Roller – Replaces Cummins 4319027 / 3679868 – ISX15 QSX15 X15 Diesel Engine

Description

MB4A –

Interstate Mcbee is a new aftermarket injector rocker cam follower roller used in the valvetrain/rocker housing assembly on select Cummins heavy-duty diesel engines.

Cummins 4319027 is identified in engine parts catalogs as a cam follower roller, and PAI catalogs 045088 as the replacement for this injector/valve roller application. Interstate-McBee also lists its corresponding injector rocker roller as M-4319027 in Cummins ISX / QSX / X15 applications.

This roller is used in the injector rocker assembly where it rides against the camshaft and transfers cam motion through the rocker mechanism. Proper roller condition is critical because wear, pitting, flat spotting, or bearing failure can damage the camshaft and affect injector actuation.
