Mercedes part number A209 800 07 72
Engravings on the cylinder do not match the Mercedes part number - they are serial numbers and internal references. There are three lines of engraving on the original part. The middle line will typically be 1648-030-B or 1648-030-C or 1648-030-D or 1648-030-E
This is the left side cylinder that lifts the main portion of the soft top (together with the right side cylinder - note that the left side cylinder is different with three ports for hydraulic lines, as opposed to two ports on the right side cylinder. Left side and right side tend to fail at almost the same time.
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 $200 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 11 on top, number 15 in the middle and number 12 on the bottom.
If your cylinder has a white ring of corrosion at the top of the shaft where it meets the clevis then it likely has some rust damage.
The corrosion and rust damage is most often caused by water intrusion due to a failed weather seal on the vehicle.
If your cylinder has a rust damaged shaft we can replace it, but there is an additional charge of $100 for a replacement shaft.
We will only subtract $50/ea from the core refund for corroded shafts if ordered with core exchange method.
