pontiac g6 convertible hydraulic pump manufacturer

The most common failures on these pumps are gradual pressure loss or a burnt out motor. Top Hydraulics rebuilds these pumps and makes them perform better than brand new ones. We replace and upgrade internal seals, check tolerances on check valves, pistons, rotor, and stator, as well as solenoid valve performance. Burnt out motors get rewound or replaced, and internal components get upgraded. Thorough bench testing for flow, pressure, and thermal behaviour ensure that you get back a pump that performs beyond original factory specs.

The G6 has seven hydraulic cylinders that activate and latch/unlatch the folding top, powered by one hydraulic pump. The hydraulic cylinders typically fail first in the rear (bottom) of the cylinder. The OEM (Original Equipment Manufacturer) cylinders have front and rear caps that are sealed from the cylinder bodies with a seal material that decays over time. Top Hydraulics replaces those seals with a far superior material that is not sensitive to water and is resistant to most additives in hydraulic fluid. Our seals have a larger cross section for a superior static seal.

Top Hydraulics manufactures and installs its own precision CNC machined front caps in these cylinders, so that the tiny OEM rod seals can be replaced with Top Hydraulics" own u-cup seals for a far more reliable seal and much longer service life. In addition, the size and geometry of Top Hydraulics" u-cups is forgiving to tiny scratches and imperfections in the cylinder rods (aka piston rods or shafts), caused during the original manufacture, during removal from the car, during installation into the car, or by impurities in the hydraulic fluid.

Top Hydraulics replaces the port seals (where the hydraulic hoses attach) and ships spares with each cylinder, in case your mechanic accidentally pinches an o-ring while installing the hydraulic hose.

Owning and driving a convertible with an automatic top is prestigious, convenient and exciting - let Top Hydraulics help you enjoy your beautiful car even more by making your convertible top system truly better than new!.
