Top Lock (Front Lock) Cylinder

Mercedes part number 2098001172. Mercedes does not put this part number on the cylinders.

Engravings on the cylinder do not match the Mercedes part number - they are serial numbers and internal references. There are typically three lines of engraving on the original part. The middle line will typically be 1605-030-C

This is the cylinder that latches the front of the soft top to the windshield. It tends to leak first through the bottom mounting hole, where the mounting pin goes through the housing.

Top Hydraulics makes these parts better than new inside, with seven new, superior seals and reinforcement against the occasional "explosion" known to happen on OEM cylinders' bottoms. There is a lot of precision machining involved, new CNC-machined glands to accommodate the improved rod seals, and Top Hydraulics' signature wiper seal, which keeps dirt and water from entering the gland. Comes with new O-rings to put on the hoses when you install the cylinders, and an illustration on how exactly to install the O-rings.

You send in your cylinder for rebuild first (then we rebuild it, then we ship it back to you), or you pick the up-front shipping option (aka core exchange) which adds $30 surcharge plus $120 refundable deposit. Core exchange means we send the parts first from our inventory, then you send back your cores (original cylinders) to recover the core deposit. The deposit gets refunded in full to the original payment method once we receive a matching core without serious damage to the metal parts.

Hydraulic line hook-up: number 65 on the shaft side and number 66 on the bottom.

For Rebuilding Your Cylinders:  Once we receive your cylinders, the turn around time is up to two business days for rebuild service and we will ship the cylinders back to you by Priority U.S. Mail (2-3 days delivery time).

Seals used by Top Hydraulics, Inc. include Viton™ and Teflon™-hybrid seals, as well as enhanced Polyurethane material, which far exceed the OEM's requirements for rigidity, but provide at least double the service life for your convertible car top actuators, based on scientific test data.
