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:

Cylinder Packing Instructions

Place the cylinder hose ends into a bucket and remove fluid by extending and retracting the cylinder rod end-to-end several times. Be sure to point the cylinder hose ends into the bucket and away from yourself.

Retract the cylinder rod into the cylinder housing and place in a plastic bag to contain any residual hydraulic fluid. Wrap the cylinder with bubble wrap, foam or anything else that will protect it from getting damaged.
