Cleveland Wheels & Brakes 40-77G Nose Wheel Assembly

The nose wheel assembly is located under the nose of the aircraft and is the third wheel of the landing gear system. The nose wheel design consists of two halves bolted together with a tire mounted and ultimately mounted to the nose gear fork. Nose wheels are designed to support a portion of the load requirements for the aircraft along with the main wheels. The nose wheel provides a means of steering control, if so equipped. The main wheels transmit stopping forces from the brake to the ground. Wheels are made from either aluminum castings, magnesium castings or aluminum forgings. The wheel is of the divided type, incorporating inner wheel half and outer wheel half, which are fastened together with tie bolts, washers and nuts. The wheel rotates on two tapered roller bearings which seat in bearing cups, shrink fitted into the hubs. Molded grease seals provide protection and lubricant retention for the bearings. Hubcaps, when used, are secured to the outboard wheel half by a snap ring and screws.
