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!

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.
