Rebuild service for BMW 2-Series Hydro Unit aka Hydraulic Pump

$400.00

You send in your malfunctioning BMW 2-Series (F22) hydro unit, and Top Hydraulics rebuilds it. The rebuild includes electric motor replacement or rewinding if necessary, 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. Three years warranty.

No sales tax for orders in the USA

 

We provide world class technical support

 

3-year standard warranty (should last decades)

Turn around once we have your rebuildable pump and payment is 1-3 days. Additional cost applies if the reservoir arrives broken or the aluminum ring around the motor has been crushed beyond repair. Please wrap the pump in absorbent material and put plastic bags around it, buffer your parcel well inside, ideally double-box, and tape up well. Take special care to protect the thin aluminum wall at the end of the reservoir from getting crushed in transit - it seals the end of the reservoir. Top Hydraulics ships back inside a USPS Priority Mail Large Flat Rate Box - $15 inside the US and $80 internationally.

The most common failure symptom on used BMW 2-Series hydro units is a gradual loss of pressure and power. Beware when purchasing used pumps that those may actually be units that are still pumping, but are not able to complete the convertible top's opening or closing cycle.
