Auto P ump Rebuilding Kit (with bearing) for 091-9 Auto-Pump is a small air compressor designed to mount on vehicles with air brakes to maintain the air pressure in the air brake system while the vehicle is not in use. A pressure switch senses when the system pressure drops and starts the compressor which then runs until pressure is restored. All ball bearing construction, lubricated for life, assures reliable operation and requires no servicing.
