The bush, code number K 32306, serves as a key intermediary element between housing K 32301 and the bearing insert K 32329. Its function is to provide a smooth surface for the bearing insert to operate against while also absorbing minor vibrations and accommodating thermal expansion. This enhances both mechanical reliability and component durability in the high-performance environment of the ZV40/48 engine. Its robust design ensures that operational forces are evenly distributed, contributing to reduced maintenance needs and extended service intervals.
