The locking ring identified by code K 72145 is used to secure the flexible rod K 72135 within the Sulzer ZV40/48 engine system. It holds the rod firmly in place, ensuring accurate alignment and preventing unintended movement during engine operation. This is particularly important in systems where mechanical stability and precision are critical, such as fuel or lubrication controls. Constructed to withstand mechanical stress and vibration, the locking ring supports both safety and reliability across extended engine service intervals.
