Hydraulic Pump + All 11 Hydraulic Cylinders - Mercedes R230 SL-Class

includes roll-bar cylinders

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 an option that closes the trunk lid from the fully open position from the key fob.

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.
