Products – Mercedes-Benz SL/SLK Vario-Roof Front Latch Cylinder Fix

Mercedes-Benz vario-roof front latch cylinders are located under the front edge of the roof and above the top center portion of the windshield frame of the R170, R171, and R230 chassis. The front latch cylinder can now be easily removed from the car by cutting the hoses near the cylinder. This will significantly reduce the amount of labor that is normally required to remove the cylinder with the attached hydraulic hoses all the way back to the pump. Our rebuilt cylinders will be shipped back with the couplers already attached, allowing for quick installation. Hoses are permanently reconnected via the couplers* with basic hand tools including 3/8” box wrench, vise grips, and pliers. Mercedes-Benz vario-roof front latch cylinder part numbers include:

Our rebuilt cylinders carry a 3-year warranty. If a cylinder fails within the 3-year warranty period, we will repair the cylinder at no charge.

Not covered by the warranty: hydraulic cylinder and/or hose damage caused by mishandling, improper installation, and malfunctioning convertible top system components.

Cylinder Packing Instructions:

Point the cylinder hose ports or hose ends (where applicable) into a bucket and remove fluid by extending and retracting the cylinder rod end-to-end several times. Be sure to point the cylinder ports into the bucket and away from yourself.

Push the cylinder rod completely into the cylinder. Wrap the exposed cylinder rod with bubble wrap, foam or anything else that will protect it from getting damaged. Place in a plastic bag to contain any residual hydraulic fluid. Wrap each cylinder individually before placing it in the shipping box. Pack plenty of space filler to keep the cylinders from shifting around.
