To order directly from our inventory, select "Order now with core exchange" 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 $60.}

Rebuild & Upgrade Service for your Z3 Hydro Unit (hydraulic pump)

You send us your pump to be rebuilt and upgraded. Includes replacement of electric motor if needed, overhaul of valves and internal parts of the pump assembly to exceed manufacturer's specs. The finished product gets a full bench test for flow, pressure, and thermal behavior.

Drain the fluid from the pump before shipping to Top Hydraulics, wrap the pump inside a large garbage bag (or two...), buffer the parcel well inside, consider double boxing, and tape up well on the outside. A USPS Priority Mail Medium Flat Rate Box works well.
