[QUOTE="totaleq0111, post: 73602, member: 10487"] Okay this thing has only 90psi of charge pressure at idle or revved up =/- 5psi when driving the machine and monitoring charge pressure it drops when the machine is put into a bind (going uphill, steering) if you run the bucket or lift arms while trying to drive the charge psi drops almost to nothing. when trying to drive moving the machine around charge psi falls to around 25-30. I really dont think this is a hydraulic/charge pump problem because the machine will lift a loaded bucket with no problem...where all can i check for charge psi problems. I have checked the charge relief in the drive pump, the case drain in the port block the filter is new fluid was changed to 15w40 valvoline. really need to get this thing going. Thanks for the help. Ps I did pull the chain cover and checked for water found it was low on oil but oil inside looked good all bearings and seals i can find seem to look good. is there brakes built into the drive motor?
