The support identified by code number K 81170 is an essential structural component used in the installation and stabilization of exhaust piping in the ZV40/48 engine. It ensures that the exhaust system is securely mounted and properly aligned to withstand thermal expansion, vibration, and operational stress. By providing a stable base, the erection support prevents displacement or misalignment of the exhaust components, contributing to a more durable and noise-reduced exhaust configuration.
