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: For locking cylinders, we will usually ship a custom made loaner wrench for easy removal of the cylinder from the lock. 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 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!

How to remove and replace your R129 Main Lift Cylinders


FedEx 2-Day Delivery
Most orders placed within the USA will ship via FedEx 2-Day Service.
FedEx Priority Overnight Service
Orders placed with FedEx Priority Overnight Service can typically ship same day as long as the order is received before 11AM Pacific Standard Time
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.

Renovated hydraulic cylinders for Mercedes SL320
Ordered on a Tueday morning - delivered Friday morning in the UK.<br /> Items installed and working - now have a convertible top that I can open and close<br /> <br /> Given that Mercees can no longer supply replacements this was a brilliant alternative<br />
