The bush coded K 32304 is a precision-engineered insert used inside the housing K 32301 of the ZV40/48 engine. It acts as a protective and low-friction interface between moving mechanical parts, especially where shafts rotate or slide. Manufactured from a wear-resistant, self-lubricating material or a high-grade metal alloy, the bush reduces metal-to-metal contact, extending the lifespan of the housing and adjacent components. Its role is vital in maintaining alignment, minimizing wear, and ensuring the smooth operation of the engine’s gear systems.
