Hydraulic Pump + All 11 Hydraulic Cylinders - Mercedes R230 SL-Class
There are two options for placing your order:
1. (Most affordable) You send in your failed components, and Top Hydraulics rebuilds them.
- Top Hydraulics replaces & upgrades ALL seals in your cylinders with our superior proprietary material including rod seals, gland seals, port seals, plug seals and piston seals. The pump rebuild includes electric motor replacement or rewinding if needed, a new high-current relay, service of hydraulic valves, and upgrade of internal seals in the pump to eliminate current or future pressure loss or internal bypass.
2. (Fastest) Core Exchange Option where Top Hydraulics ships parts from our inventory first ($2300 plus a $1000 deposit).
- Option 2 means that you get a set of rebuilt & upgraded parts from Top Hydraulics' inventory first, then you ship back your original set for credit of your $1000 core refund. You get a full set that has been rebuilt to outlast and outperform OEM replacements.
R230 SL-Class | Years: 2003 - 2012
Mercedes offered the “Remote Trunk” option in model years 2006-2012. It is not to be confused with the soft close or load assist function in all R230 trunk lids or the trunk lid popping up when it is released, but it is a rare option that closes the trunk lid from the fully open position, using the button in the driver's door.
If the trunk button in your driver's door has an up/down arrow on it as pictured below, then you have the remote trunk option. If your trunk button does not have the up/down arrow, then you don't have the rare remote trunk option.
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.
The R230's hydraulic vario roof pump aka hydraulic unit is a complex, high-performance pump with integrated valve block, two different output pressures, high-end electronic noise suppression, and high flow rate. Intermittently working pumps are often mistaken for internal leaks in R230 hydraulic cylinders. While internal leaks do occur in OEM vario roof cylinders on occasion, almost every hydraulic pump will fail eventually on account of a design flaw that Top Hydraulics fixes with its upgrade.
The upgrade service for hydraulic convertible top pumps replaces sensitive parts inside the pump with re-designed, precision machined aluminum ones, improves fluid filtering, services the valve block, solenoids and check valves, upgrades electronic components, upgrades internal seals, and replaces the electric motors if needed. Early model year vario roof pumps p/n 2308000030 aka A 230 800 00 30 fail very frequently at this point, and should be upgraded proactively. Top Hydraulics' service makes these high-performance pumps better than brand new ones!
Pump P/N 2308000030, 2308000088, 2308000330, 2308000348, aka A 230 800 00 30, A230 800 00 88, A230 800 03 30, A230 800 03 48.
Do not ship the rollbar-related cylinders (pawl lock cylinders 2308001672/2308001772 and roll bar lift cylinder 2308001872) mounted inside the roll bar support assembly - they are easily removed from the assembly which is heavy, awkward, and expensive to ship. Please ship the hydraulic pump without the mounting frame, or we will have to charge extra for return shipping. Shipping charge within the US is $30, shipping via FedEx 2-Day Service.
International shipping rates vary, please contact us for an exact shipping quotes. We ship internationally via FedEx International Priority, which delivers to most locations within 3-7 days. Shipping to most countries is in the $150 range.

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.
