There are two options for placing your order:
1. (Most affordable) You send in your leaking Rear Lock Cylinder, and Top Hydraulics rebuilds it.
- Top Hydraulics replaces & upgrades ALL seals in your cylinder with our superior proprietary material including rod seals, gland seals, port seals, plug seals and piston seals. Top Hydraulics' u-cup seals have a far more reliable seal and much longer service life.
OR
2. (Fastest) Core Exchange Option where Top Hydraulics ships the part from our inventory first ($85 plus a $100 deposit).
- Option 2 means that you get a rebuilt & upgraded cylinder from Top Hydraulics' inventory first, then you ship back your original part for credit of your $100 core refund. You get a cylinder that has been rebuilt to outlast and outperform OEM replacements.
P/N 1298002172

Rear Lock Cylinder
This cylinder is located in the rear latch, pulling down the rear of the soft top. It is highly recommended to upgrade these actuators in pairs.
Convertible hydraulic cylinder rebuild/upgrade service for Mercedes R129 models 300SL, 500SL, 600SL, SL320, SL500, SL60, SL600, SL73.
Top Hydraulics Offers two options for upgrading cylinders for Mercedes convertible tops.
For Rebuilding The Cylinders That You Send In: We gladly accept the cylinders in their locks/latches at no extra charge -- you save the extra labor and we have all the assurance that the cylinders do not accidentally get scratched upon removal from the locks.
To order with Core Exchange: Core deposits will be refunded in full if we receive your matching cores within 90 days, and the cylinder rods are unscratched. A small "rental charge" may apply if the cores get returned later than 90 days from receipt, but we are usually extending the return period within reason without such a rental charge.
Metal parts in your hydraulic cylinders do not get damaged during normal operation. Sealing surfaces (for example the polished, chromed cylinder shafts sliding through the rod seals) can easily get scratched beyond repair by tools - especially during DIY repair attempts. Top Hydraulics can replace any damaged metal parts but has to charge extra for that service.
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 more than double the service life for your convertible car top actuators, based on scientific test data. Making your roadster/cabriolet hydraulics better than new!
Part Number - 1298002172 (AKA A129 800 21 72)
Please note that Model years 1990 and most of model year 1991 were originally equipped with p/n A1298000072 in the rear locks, which have 6-mm shafts and M5 threads at the ends of the shafts. For comparison, the shafts in the tonneau cover lift cylinders A1298002072 next to the rear locks have 6-mm shafts. The complication is that Mercedes would have sold p/n A1298002172 if anyone had tried to replace the rear lock cylinders with new ones from Mercedes. (The wisdom of that move alludes us, as Mercedes still sold the complete lock assembly with an A1298000072 in it.) P/N A1298002172 has a 9-mm shaft and an M6 thread at the end of the shaft. Thus, to install p/n A1298002172 in the rear lock of model year 1990 or 1991, you will have to tap an M6 thread where there used to be an M5 thread. Conversely, p/n A1298000072 can be installed into a lock that already has an M6 thread in it by securing it with two M5 washer and an M5 nut. If you have an model year 1990 or 1991, then best compared the shaft diameter of the cylinder in your rear lock to that of the A1298002072 tonneau cover lift cylinder next to it and order p/n 1298000072 (tonneau cover lock cylinder) instead if needed.

FedEx International Priority
For Customs clearance, you must declare a value on the package you are sending us. Please note: parcels with a declared value under US$750 enter the US without incurring taxes, duties or clearance fees. Considering that you are sending us broken parts for repair, it is most reasonable to declare a value under US$750. You can insure your parcel only up to the amount that has been declared as the value for customs, so your best insurance is good packaging. It is extremely rare that parts get lost on the way to us.
Please be sure to drain or cycle all fluid out of your parts, then wrap them in plastic, so that the parcel does not get soaked in oil. It is generally a good practice to double box pumps or sets of cylinders because heavy parcels take quite a beating in international transit unless you are using a premium carrier such as FedEx. Clearly, you don't want to just stick a part into a cardboard envelope without any further protection or buffering. Buffer your parcel well inside so that parts don't rattle around or the parcel gets crushed from others on top of it. Ideally, tape all around all surfaces of the parcel, which generally provides excellent protection against losing components that are trying to escape through small holes in the cardboard.
We use FedEx International Priority for almost all outbound international shipments, as they tend to offer the fastest and most secure service. Due to our shipping volumes, our rates for return shipping your parts via FedEx International Priority are typically equal to or cheaper than Postal Service. We cannot offer shipping labels for your shipment from you to us - you will have to shop around for the best option to ship your parts to us.
In the rare event that you feel you have to declare a value over US$750 on your parcel shipping to us, please understand that we will need to be reimbursed for any importation fees or duties incurred. You agree to this by accepting our terms and conditions when you place your order. On high value parcels, we are typically charged an Entry Prep Fee (currently about $25) plus 2.5% tax on the declared value of the package, there are oftentimes delays in customs, and it can take a while for us to receive the actual customs invoice.
Depending on the parts you are sending us, your customs declaration might say "hydraulic cylinder for repair" or "hydraulic pump" for repair. Please note that DHL does not like to carry hydraulic parts or used car parts in some countries. If your carrier asks for the "harmonized code or tariff" of the parts you are shipping, those are 841221 for linear actuators (cylinders) and 841360 for pumps.
At Top Hydraulics, we pride ourselves on providing new and remanufactured parts with unmatched quality and longevity.
It is very rare that our parts fail. Obviously, we are only human and we could have made a mistake or one of our components might indeed have had a hidden defect. Please contact us first when you suspect that you have a warranty case, so that we can try to help right away. It could be that the failure you are experiencing is caused by a different component or that the installation was not quite proper, so we like to be in touch first to go over the situation with you.
Unless stated otherwise, there is a 3 year warranty on all new and remanufactured parts provided by Top Hydraulics. This warranty is transferable. All parts manufactured or rebuilt by Top Hydraulics have unique markings, so there is no additional paperwork needed to transfer a warranty. The warranty does not cover labor, direct or consequential damages. The warranty is void when the parts have been abused or have been installed incorrectly, or when brake fluid or stop-leak additives have contaminated your hydraulic system..
You will have to send your failed part(s) back to Top Hydraulics for a warranty evaluation. In the extremely rare case of failure on rebuilds or new parts shipped or provided by Top Hydraulics, Top Hydraulics' warranty covers only parts and is limited to rebuilding the products previously shipped by Top Hydraulics, or replacing them, or refunding the rebuild fee at Top Hydraulics' discretion. If the failure was our fault, then we will refund reasonable shipping costs, as well.
