Liftgate Hydraulic Pump Mod Help on M820A2 Needed

[goldneagle]

I am thinking of replacing the 3 phase hydraulic pump that runs my liftgate on the M820A2 with the engine off. This is a the backup pump used when the truck is plugged into a 3 phase generator for power. It allows the operator to operate the liftgate without having to run the engine and PTO.

I have not tried to read the motor specifications from the tag on the motor. Its all painted over.. May have to pull the entire assembly to get to it. I am pretty sure its a continuous duty motor and pump that circulate hydraulic fluid to the liftgate and is controlled by solenoid or pressure switches. It is attached parallel to the PTO pump.

I would like to change the motor or motor/pump with one that operates on either 24v DC or 120 volt AC.

I have a 12v hydro pump, should run fine on 24v. No clue on pressure or gpm.

Do you have any pictures? Asking price?

I'll see if I can find it and let you know.
