The flywheel assembly is a critical rotating component bolted to the engine crankshaft. Its primary role is to store rotational energy and smooth out the power pulses produced by each combustion cycle, keeping the engine running evenly under the variable load demands of a concrete pump. A flywheel that is cracked, damaged, or out of balance can cause noticeable vibration, rough engine operation, and accelerated wear on the crankshaft and surrounding drivetrain components — making timely replacement essential to maintaining consistent pump output and engine longevity.
