Rebuild/Upgrade Service for your Corvette C6 Convertible hydraulic pump. You send us your malfunctioning pump, and we service the electric motor and the valves, plus upgrade internal seals in the pump. (Or use the core exchange option and we will ship a pump from our inventory first). Pistons get checked for tolerance, the piston assemblies get replaced if necessary, and the pump goes through a detailed test procedure to make sure that pressure and flow in both directions exceed manufacturer's specs. An extended load test ensures that the pump does not overheat. All internal seals get replaced and upgraded to make this pump better than a new one inside. Return shipping is $20 for US domestic orders, or $90 for most international orders.
The hydraulic pump is located in the tonneau compartment. The hydraulic system also utilizes two main lift hydraulic cylinders, two bow cylinders, and two tonneau cylinders. In the tonneau hydraulic circuit there is a hold valve to prevent the tonneau cover from closing when there is no operating pressure.
The hydraulic pump consists of a pump block, oil reservoir, and a 12-Volt DC electric motor to operate the pump. The fluid reservoir (with level indications on the side ) is attached to the pump with a hose clamp. Chevrolet recommends using Univis HVI 26 hydraulic fluid. Here at Top Hydraulics, Inc. we use FeBi 02615 fluid in all of our hydraulic systems.
