Rebuild/Upgrade service for your Corvette C6 Right Tonneau Cylinder
P/N: 89023778
Top Hydraulics' standard warranty is 3 years on rebuilds/upgrades of convertible top cylinders and hydraulic pumps, and on new hydraulic hoses.
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.
