644E brake pump/pilot control settings

Merlejoe22 · 2021-01-06 10:29

Hi guys, I took a look around but couldn’t find anything on this so here I am. I just had the brake pump rebuilt in my machine it’s a 644E Deere loader. (Sorry no Vin) I’m ready to install the pump back on the machine and I don’t have the procedure for the pressure setting for the pump. Does anyone know the procedure for setting up this application? Thanks.

    Just found the info for this. Pump is set to 2000 psi constant pressure.

    Looks like Sundstrand series 15 (open loop configuration) or it’s Daikin brother.

    Brake pump standby pressure is 2350 +/- 50 psi.
