The World American WA902-03-2119 is an aftermarket replacement belt tensioner for compatible Cummins ISB/C applications.
This tensioner replaces Cummins 5270678 and is designed to maintain proper belt tension in the belt drive system. Replacing a worn tensioner helps prevent belt slip, squealing, uneven belt wear, and poor belt tracking.
A failing belt tensioner can cause noise, vibration, belt misalignment, or reduced performance from belt-driven components. The WA902-03-2119 is a direct replacement option for repairs where Cummins 5270678 is called for.
