Automatic Locking Hubs Explained - Top

IH Scouts were shipped with at least two different styles of automatically-locking front hubs. These two styles were designated "Lock-o-Matic" and "Auto-Matic".

These hubs have two dial positions, labeled "AUTO" and "LOCK". ("FREE" and "LOCK" on the "Lock-O-Matic" hubs.) When in "LOCK", the hubs function just like a manually-locking hub. When in "AUTO" or "FREE", however, these hubs will free-wheel until torque is applied to the front axle shafts. When the transfer case lever is pulled, and torque is applied to the front axle drivetrain, friction pads are engaged inside the hub and the hub acts as though it were locked. This locking action is effective in both forward and reverse, just as in the case of a manually-locking hub. The only circumstance where these hubs are NOT locked (when a manually-locking hub WOULD be) is under engine- or compression-braking.

A thin coating of light grease is sufficient for the internal parts of any "selectable" hub style. Automatic locking hubs, however, are particularly vulnerable to failure from over-greasing. Packing the entire hub interior with thick grease can prevent the hub fron disengaging properly. One or more hubs that fail to unlock properly can cause the entire front drivetrain to be "driven" in reverse from the rolling tires, even when the transfer case is in 2WD
