Glad I checked this nylon gear and loose as hell. probably would not have survived the planned long trip. Have a nice roller chain coming or it. This is a 64 BUICK 401, but Buick used a similar design on their other engines for the water pumps. The 1/4 bolts are notorious for breaking. If you soak them with penetrating fluid and work them easy, they usually come out.
