Convertible Top Hydraulic Cylinder: Service and Repair

Power Folding Top Cylinder Replacement

Removal Procedure

Each hose consists of 1 white and 1 pink hose bundled together. The upper hose controls the left cylinder. The lower hose control the right cylinder. The pink hoses attach to the top of each cylinder. The white hoses attach to the bottom of each cylinder.

Ensure the hoses remain connected as indicated. If the hoses are switched, 1 cylinder may extend while the other cylinder retracts. This will damage the folding top.

Important: When servicing the hydraulic system, leave the folding top raised and unattached from the windshield header in order to keep the cylinder rods extended and minimize fluid leakage.

1. Turn the pump bypass valve fully clockwise to the open position.

Caution: Refer to Battery Disconnect Caution in Service Precautions.
