Audi Convertible Hydraulic Cylinder Rebuild/Upgrade Service

Audi

  • We upgrade your cylinder(s) by replacing the tiny OEM rod seal with a much larger one made of superior materials in a superior geometry.  We then add custom glands made of CNC machined stainless steel to accommodate these superior seals. Our seals are more forgiving towards unevenness of the surface that slides through them, they 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.

  • Our Core Exchange option makes this as easy as buying a new cylinder - you only have to ship back your old cylinder(s) afterwards for core credit. Top Hydraulics' also rebuilds and upgrades convertible hydraulic pumps, as well as manufacturing our own upgraded hydraulic lines.

  • 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!

  • Top Hydraulics' standard warranty is 3 years on rebuilds & upgrades of convertible top cylinders and hydraulic pumps, and on new hydraulic hoses.

Audi A3 Convertible 2013-Present Top Hydraulic Rebuild & Upgrade Service

Audi A3/S3 '13-'20

Audi A4 Cabriolet 03-07

  • Top Hydraulics offers rebuild service and core exchange for all Audi A4 Cabriolet convertible top cylinders as well as the pump unit, and Top Hydraulics manufactures new hoses that are longer lasting.

  • The most common problem on your convertible is pump failure with intermittent operation and eventually no top movement at all. Top Hydraulics offers convenient core exchange with pumps already filled with hydraulic fluid - you don't even have to buy hydraulic fluid. Pump removal and replacement is easy, and it's plug & play.

  • We upgrade your cylinder(s) by replacing the tiny OEM rod seal with a much larger one made of superior materials, 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.

  • The system has six cylinders: Two main drive cylinders aka folding top cylinders: p/n 8H0871795B (same LH and RH) Two bow tension cylinders aka tension lever cylinders: p/n for the left side 8H0871603B, p/n for the right side 8H0871604B Two case cover lift cylinders: p/n for the left side 8H0871607B, p/n for the right side 8H0871608B The Hydraulic Pump p/n is 8H0959247B or 8H0871611B, depending on how much of the assembly you are referring to. The part number 8H0 871 611 B applies to the complete pump assembly with three-solenoid valve block. Typically, rebuild service is only needed for the part that detaches from the valve block (and is easy to take out of the car that way), which is p/n 8H0 959 247 B. This is the actual pump with the electric motor on one end and the hydraulic fluid reservoir on the other end. It is held in place by a single Allen bolt (6-mm inside hex).

  • Important: Polished cylinder shafts must be free of rust or scratches from tools for a successful rebuild. If the shaft needs to be replaced, there will be a surcharge for shaft replacement with a hardened stainless steel shaft manufactured by Top Hydraulics.

Send in your pump first, and Top Hydraulics will rebuild and upgrade your pump to exceed factory specs for a fraction of the price of a new replacemen

The pump ships back to you filled with fluid. Please be sure to drain the old fluid from your pump before you send it to us.

Top Hydraulics fully rebuilds and tests your pump before sending it back to you. This includes service and repairs to the electric motor, upgrade of some motor components, resealing of the pump unit, inspection of all pump components such as pistons and impellers (replacement if they are not to spec), and extensive testing for output pressure, output flow, long term performance, and thermal behavior. We keep the tolerances so tight that no pump will ship without at least exceeding factory pressure specs by 5%.

Audi P/N 8V7871791, manufacturer's reference DAI1-124207

Your pump will be fully rebuilt and will exceed OEM pressure specs by at least 5%. Three years warranty.
