Abstract
A tire changer apparatus comprises a rotor operative to support a wheel rim. A toolhead is movable into engagement with the wheel rim during a tire changing operation. A gas distribution network is provided for routing compressed gas to pneumatic mechanisms in the tire changing apparatus. An oil injector has an outlet in fluid communication with the gas distribution network. The oil injector is operative to introduce lubricating oil into the gas distribution network. Preferably, the oil injector may include a plunger which reciprocates to inject the lubricating oil. For example, the oil injector may be operative to introduce the lubricating oil into the gas distribution network when the plunger reciprocates a selected number of times. The plunger may be moved by a foot pedal on the tire changer apparatus.
