Removed in serviceable condition from undamaged aircraft.  Full refund if not satisfied for any reason.  

Will work on 75 E, all F model and Nay UO-1.  Will also work on Apache and all other 12v Aztec models with electric motor, circuit breaker and relay change.  Made by the Dee Howard co. In San Antonio.   They are no longer in production. I have sold these in the past and they have always been very helpful and polite and have issued the STC for no charge.  The pump and motor are made by Adel and are still supported by many accessory overhaul shops.

I am missing the micro switch and mounting tab that mounts adjacent to the gear selector handle.  You will have to source a momentary on switch and fabricate a mounting tab.

The pump is activated when the gear is selected to the up position and deactivates when the gear finishes it’s cycle and the handle returns to the neutral position.  The gear will go up twice as fast.  It’s primarily purpose is to retract the gear in the event of a left engine failure.  It is very cumbersome and time consuming to pump the gear about fifty strokes while trimming/troubleshooting etc.  It also can be utilized in the event of an engine driven hydraulic pump failure to operate the gear or or flaps by selecting the desired position and simply depressing the exposed switch.  It also takes the place of the hand Pump or hydraulic mule when operating the hydraulic system on jacks or for operating the flaps during preflight inspection. You can also extend the gear at twice the normal speed in the same manner.

It mounts in the left nacelle aft of the firewall to the tubular engine mount/gear actuator support truss with the 4 Adel/DG clamps provided.  It requires a power and ground wire in addition to a wire from the cockpit mounted momentarily on micro switch.  The hydraulic plumbing is simple-installs in series with engine driven out (pressure) line
