sl55 hydraulic pump supplier

Top Hydraulics" cylinder rebuild service is widely known as the best possible option, even if you are an excellent Do-It-Yourselfer. Note also our rebuild service for hydraulic valve blocks, distributors, and pumps, as well as manufacture new, superior hydraulic hoses.

Model years 1990-1996 have twelve hydraulic cylinders, while 1997-2002 models have eleven hydraulic cylinders that move and lock the roadster soft top. (The left tonneau cover lock was omitted after 1996.) The original seals in the hydraulic cylinders, aka rams or actuators, will eventually fail in every R129, unless it gets wrecked prematurely, even if you never drive the car or have never used the top before. Rebuilding these cylinders is NOT a matter of changing o-rings. Every R129 cylinder has one o-ring, and those rarely ever fail. What fails most frequently, are the other seals, which have special shapes for proper function.

2) Piston seals. They seal the input and output sections from each other, as the piston slides through the cylinder. The piston seals have been made of different materials and sizes even in the same p/n cylinders throughout the years. Failing piston seals will cause internal leaks, which result in a pressure drop in your hydraulic system. Early model years have the added problem that the piston seals swell up and make it very hard to move the piston inside the cylinder. Crumbling piston seals can block valves or pinholes inside the hydraulic system, and it can be difficult to diagnose a piston seal failure without testing several cylinders once you find that your top is moving slowly or not at all.

4) Port seals. They seal the hydraulic lines where they are pushed into the cylinders. Port seal failure is becoming more and more common as the R129s age. It also applies to the front distributor p/n 1298000022. Port seals have a special shape that makes them seal under pressure. O-rings wouldn"t do the trick. They are secured by precisely machined brass rings (accuracy about 1/100 mm). DIY removal of the brass rings will almost certainly destroy the brass rings. Top Hydraulics installs port seals that are tighter than the originals, just in case the hydraulic line fittings have been scratched. Cylinders and distributors upgraded by Top Hydraulics should easily outlast your car!

For Rebuilding Your Cylinders: You must send your convertible hydraulic top cylinders to us. Once we receive your cylinders, the turn around time is up to two business days for rebuild service and we will ship the cylinders back to you by Priority U.S. Mail (2-3 days delivery time).

Model years 93-95 have eight hydraulic cylinders that move and lock the convertible soft top. The original seals in the hydraulic cylinders, aka rams or actuators, will eventually fail in every W124, unless it gets wrecked prematurely, even if you never drive the car or have never used the top before. Rebuilding these cylinders is NOT a matter of changing o-rings. Every W124 cylinder has one o-ring, and those rarely ever fail. What fails most frequently, are the other seals, which have special shapes for proper function.

Top Hydraulics" cylinder rebuild service is widely known as the best possible option, even if you are an excellent Do-It-Yourselfer. Note also our rebuild service for hydraulic valve blocks, distributors, and pumps, as well as manufacture new, superior hydraulic hoses.

We have two order methods: Either you send in your cylinders first, or choose to "Order now with Core Exchange".  Core exchange currently available for the R171 SLK front lock cylinder, the full set cylinders, and the hydraulic pump unit. There is a $30 surcharge per cylinder for this service, PLUS a refundable deposit of $1000 for the full set. Core deposit will be refunded after we receive your old front lock cylinders back with lines attached and intact, as well the shaft not being scratched by tools. Either scratched shaft or damaged lines result in reduced core refund. Top Hydraulics manufactures replacement shafts and replacement hoses, but there is significant cost involved.

If you send your cylinders in for rebuild service, Top Hydraulics averages a 2-day turn around time. Front lock and main lift cylinders must be received with lines attached and intact. The lines on the trunk lid cylinders are detachable.

The Vario Roof hydraulic system has eight or nine actuators and/or latch cylinders (depending on model year), including the trunk"s load assist, PLUS two pawl lock cylinders and one roll bar lift cylinder. All cylinders have the hydraulic lines attached and must be shipped in that condition.

The seals in ALL these cylinders fail with time. Usually, the roof lock cylinder 2308000872 aka A 230 800 08 72 is first to leak. If you live in a hot climate and you have noticed a hydraulic leak, then having Top Hydraulics upgrade all eleven cylinders and the pump at the same time is the best choice - you will have to deal with the hydraulics only once, you save a lot of labor in the end, and the convertible top hydraulic system will outlast your car.

Top Hydraulics" rebuild service is a true upgrade, since the rebuilt cylinders will last much longer than the originals under the same conditions, and a design flaw gets eliminated from the otherwise excellent hydraulic system.

The hydraulic lines are not detachable from the cylinders. That means the cylinders have to be shipped with lines attached and intact. Top Hydraulics can replace cut lines on the cylinders, but there would be an additional charge.

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. The upgrade service for your hydraulic top pump replaces heat 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 and 2308000348 aka A 230 800 00 30 and A 230 800 03 48 fail very frequently at this point, and should be upgraded proactively. Top Hydraulics" service makes these high-performance pumps better than brand new ones!

The R231"s hydraulic 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. The upgrade service for your hydraulic top pump replaces heat 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.

The W208 CLK-Class convertibles have seven hydraulic cylinders for convertible top actuation and latching. The two aluminum latching cylinders 1298001672 and 1298000072 are usually the first ones to fail, and should be upgraded at the same time. The five black lift cylinders 2088000x72 usually follow as a second stage.

We upgrade your 2088000x72 cylinder(s) by replacing the tiny OEM rod seal with a much larger one made of superior material, and adding custom caps made of CNC machined stainless steel to accommodate these superior seals. Our seals are not sensitive to water and are resistant to most additives in hydraulic fluid. This results in a much longer service life than the standard OEM cylinders, for a fraction of the price.

Owning and driving a convertible with an automatic top is prestigious, convenient and exciting - let Top Hydraulics help you enjoy your beautiful car even more by making your convertible top system truly better than new!

These cylinders typically fail first in the rear of the cylinder. The OEM (Original Equipment Manufacturer) cylinders have front and rear caps that are sealed from the cylinder bodies with a seal material that decays over time. Top Hydraulics replaces those seals with a far superior material that is not sensitive to water and is resistant to most additives in hydraulic fluid. Our seals have a larger cross section for a superior static seal.

Top Hydraulics manufactures and installs its own precision CNC machined front caps in these cylinders, so that the tiny OEM rod seals can be replaced with Top Hydraulics" own u-cup seals for a far more reliable seal and much longer service life. In addition, the size and geometry of Top Hydraulics" u-cups is forgiving to tiny scratches and imperfections in the cylinder rods (aka piston rods or shafts), caused during the original manufacture, during removal from the car, during installation into the car, or by impurities in the hydraulic fluid.

Top Hydraulics replaces the port seals (where the hydraulic hoses attach) and ships spares with each cylinder, in case your mechanic accidentally pinches an o-ring while installing the hydraulic hose.

Various options are available - please inquire if you do not find the exact match in our online offering. Top Hydraulics services and upgrades pumps, upgrades the seals in the cylinders, and replaces hydraulic hoses if necessary with far superior material. Why buy new parts - you will get a superior product back from Top Hydraulics at a fraction of the dealer price.

The seals inside these cylinders are similar to those in other convertibles and lift gate cylinders: they decay with time. Otherwise, the cylinders do not normally wear out (unless they are grossly mistreated and get damaged on the chromed shafts). Thus, with Top Hydraulics" superior seals in your cabriolet hydraulics, they will be better than brand new parts.

Top Hydraulics does not currently stock the G-Class convertible hydraulic cylinders p/n 463-805-00-01; you will have to send in yours for rebuild/upgrade service. Please contact Top Hydraulics if you need individual hydraulic lines/hoses/pipes manufactured, or if you need us to rebuild your convertible hydraulic pump.

Top Hydraulics is currently servicing the lift gate pump and cylinder on a case-by-case basis. Send us your pump or pump and cylinder, we will evaluate them, and give you a price for rebuild with warranty. In most cases, the rebuild cost is between $300 and $400 plus return shipping.

Most pumps fail when they accidentally get exposed to too much moisture. The rebuild service of the electrical portion of your pump can entail replacing the electric motor, replacing the solenoid, rebuilding the motor, rebuilding the solenoid, replacing the wiring harness, repairing the wiring harness, or a combination of the above. Further to electrical issues, Top Hydraulics will always rebuild the pump by replacing internal seals, replacing rotor and pistons if necessary, replacing or rebuilding internal check valves, and putting the finished product through an extensive test to ensure that you get back a pump that performs better than a brand new one.

Strutmasters 2002-2012 Mercedes Benz SL55 Four Wheel Hydraulic Suspension To Passive Coil Spring Conversion System is the perfect solution to your computerized suspension problems. Designed to be very affordable, you can convert your ENTIRE active hydraulic suspension to use passive struts and coil springs for less than the price of replacing ONE Original Equipment strut at the dealer.

2002 Mercedes Benz SL55, 2003 Mercedes Benz SL55, 2004 Mercedes Benz SL55, 2005 Mercedes SL55, 2006 Mercedes Benz SL55, 2007 Mercedes Benz SL55, 2008 Mercedes Benz SL55, 2009 Mercedes Benz SL55, 2010 Mercedes Benz SL55, 2011 Mercedes Benz SL55, 2012 Mercedes Benz SL55

2002-2012 Mercedes SL55 Active Hydraulic Struts (x4) -A long tube (similar to a shock absorber) that fills with hydraulic fluid forced in at varying rates of pressure determined by sensors on the vehicle. The strut is a perch for a metal coil spring, which helps support the weight of the vehicle. The struts on this vehicle are considered "active" because they can be adjusted hundreds of times a minutes electronically. Much like a shock absorber, the strut dampens vibration and bouncing caused by travel on rough road surfaces. 2002-2012 Mercedes SL55 Height Sensors (x4) - A linkage located near each wheel of a vehicle that electronically measures the height of the vehicle, and reports this information back to the control module so that the computer can identify if changes in height need to be adjusted accordingly. The ride height sensor is a moving part, and like all moving parts, they will eventually wear out.

2002-2012 Mercedes SL55 Hydraulic Lines- Lines that carry fluid from a hydraulic pump to the vehicle"s active struts in order to adjust the height of the vehicle.

2002-2012 Mercedes SL55 Hydraulic Pump- A mechanical pump that delivers hydraulic fluid to the active suspension components. The pump can burn up prematurely when leaks in the suspension system cause fluid levels to get too low.

2002-2012 Mercedes SL55 Suspension Control Module- A computer responsible for the operations of the active hydraulic suspension system and maintaining the vehicle"s correct ride height.

2002-2012 Mercedes SL55 Rubber O-rings- Although they are the least expensive parts of the system, they are responsible for maintaining the seal where all of the hydraulic fluid lines connect. Bad Rubber O-rings cause leaks in the system and leads to part failures.

Look for these indicators that the factory active suspension system in the 2002-2012 Mercedes-Benz SL55 is going bad: A sudden loss of three to five inches of ride height in either the front, rear or entire vehicle. A suspension warning light, at times with a chiming noise, is another sign. Sudden loss of power steering is another indicator of a problem. Vehicle owners can check for extremely low fluid levels in the hydraulic reservoir/pump; leaks around the struts themselves; or leaks at connection points in the hydraulic fluid lines. Experienced technicians tell us that when one major component of the system has failed, the others are right behind it. A complete overhaul of the factory suspension system on this vehicle can cost in the $9,000 to $11,000 range with Original Equipment parts and labor at the dealer. The high cost of suspension repairs on the SL55 is exactly why the Strutmasters suspension conversion kit is such a popular alternative.

When one component of the "Active Body Control" hydraulic suspension suspension system goes bad, the rest of the system follows suit. This is no different for the 2002-2012 Mercedes-Benz SL55. Strutmasters built its active hydraulic suspension conversion system to save SL55 owners time, frustration, and money versus a factory system that fails over and over. Our product is manufactured in the USA and comes complete with one custom-designed suspension light fix module and four pre-assembled coil over struts that bolt right in place of the factory components. Customers appreciate the detailed instructions and online installation videos that guide the repair. If further assistance is needed, Strutmasters" technicians are available to answer questions and provide support. We use dual-action premium coil springs which eliminate the need of installing aftermarket anti-sway bars -- a time savings of more than 10 labor hours alone! Our conversion system allows Mercedes owners to enjoy these wonderful vehicles for many more years WITHOUT spending a fortune!
