45 FRONT AXLE - 4 X 4 2. Introduction When 4-wheel drive is selected, the automatic hub locks the axle shaft to thewheel hub.This occurs if the vehicle is driven in either forward or reverse direction. The hub unlocks when 2-wheel drive is selected, and the vehicle is driven in the opposite direction for a few feet. 2.1 Construction &Operation (See Fig. 1 & 2) Construction TheTangedwasher is held in place on theWheel Spindle. The cut-outs on the drag sleeve (26) fits over the tangs on thewasher,preventing the drag sleeve fromrotating.The brake band (24) fits over the serrated portion of the drag sleeve.The tangs of the brake band are fitted through the window in the steel inner cage (21). The plastic outer cage (20) fits over the inner cage. Each tang of the brake band fits through each cutout in the outer cage.The cam follower (19) is attached to the clutch gear(15). The follower profile on the cam follower (A) ride against the cam faces or ramps of the steel inner cage. The clutch gear slides on the splines on the hub sleeve (16).The axle shaft (C) is splined to the inside of the hub sleeve. The large teeth on the outside of the clutch gear can engage the teeth inside the outer clutch housing (9). The outer clutch housing is bolted to thewheel hub. An end cap (2) fits over thehubassembly.The endcapcontains abearing assembly (6) that supports theother endof thehubsleeve. The EndCap is fittedwith anAluminiumDecorative Plate for better aesthetics. Fig. 2 A D Operational Summary Briefly, this is what happens when the hub locks, The clutchgear (15) and cam follower (19) rotate up the cam face of the inner cage (21). This causes the clutch gear to move outward on the hub sleeve (16). The out side teeth of the clutch gear engage the inside teeth of the outer clutchhousing (9). locking thewheel hub to the axle shaft. When the hub un-locks. The clutch gear and camrotate in the opposite direction, backdown the camfaceof the inner cage. Springpressure forces the clutch gear inward, unlocking the wheel hub from the axle shaft.
