The bulkhead fitting flange is secured to the bulkhead on a side opposite the internal gear teeth of the slewing ring. A passage through the bulkhead fitting is provided which is capable of delivering grease through the bulkhead fitting and onto the internal gear teeth of the slewing ring. The grease assembly may include a wall fitting extending through a wall of housing supporting the bulkhead and a connecting tube capable of delivering grease from the wall fitting to the passage of the bulkhead fitting.
