Installation Centering Tool
Mack

The Installation Centering Tool is a precision instrument designed to align components during assembly and service procedures, ensuring that bores, shafts, and mating surfaces meet true centerlines before fasteners are torqued. By providing a stable reference point, it minimizes misalignment that can cause interference, uneven wear, or premature failure in heavy-duty drivetrain and suspension assemblies. This tool helps technicians reproduce accurate positioning across multiple service intervals, reducing the risk of damage from sloppy fits and costly rework. It supports proper concentricity when seating bearings, bushings, or sleeves, which translates into smoother operation, lower vibration, and extended service life for critical components. The robust construction—typically hardened steel with precise machining—offers repeatable performance in demanding shop environments and field settings alike. Using the centering tool can shorten maintenance cycles by eliminating guesswork and enabling consistent, repeatable assemblies, even when working in tight spaces on Mack trucks. For reliability and efficiency, this tool is a practical investment that pays dividends through lower labor time and improved component longevity. Source One Parts Center.
