Avoid damaging the auxiliary driveshaft bushings or journals while removing the shaft.
Note the oil feed hole in the oil metering plug at the rear of the auxiliary shaft. If this hole is plugged up, the raw water pump may fail from oil starvation. Also, the loss of oil pressure that results from a missing plug can cause damage and problems in other components and parts. Make sure the plug is not missing or the metering hole is not plugged. If replacing the auxiliary driveshaft, make sure to install a new plug.
