Shaft Drive RT45 Question


Jeff Bussell  –  Jeff.bussell538@gmail.com

Hi all Jeff Bussell here, I’ve recently purchased another austrak rt45 this one a cummins 4b engine shaft drive with recent hydraulic pumps/ motors overhauled at torque hydraulics in Adelaide. I have a slight issue with the r/h side drive pump not developing charge pressure I’ve tried blocking the port to the servos isolating them, pulled the back of the pump off and checked the charge pump drive and all seems good the charge pump pumps oil but doesn’t seem to be building pressure like there’s an internal relief valve leaking any help would be greatly appreciated thanks Jeff.
