Rebuild service for your BMW E63/E64 6-Series Hydraulic Pump Unit

New product

You send in your malfunctioning E63/E64 6-Series hydraulic pump 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.

For optional core exchange, select YES in the drop down menu above. 

Core exchange means that you get rebuilt parts from Top Hydraulics' inventory first, and then you send back your original parts for a refund of your core deposit of $250.  Core exchange option also includes a non-refundable $50 inventory management fee. For a full core refund, cylinders must be in good condition except for leaking seals.

Turn around once we have your rebuildable pump and payment is 1-3 days. Additional cost applies if the pump has been abused by fire, extended water exposure, or high mechanical impact (such as hammering or poor packaging). 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. Top Hydraulics ships back inside a USPS Priority Mail Box - $15 inside the US and $80 internationally.

The most common failure symptom on used BMW E63/E64 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. Contact us with questions.
