[QUOTE="Tazza, post: 9610, member: 82"] Ok, i am pretty close to finishing my third restored/painted 743. One thing i thought others may be interested in is re-priming the hydraulic system. When i removed all the parts i drained ALL the oil from the pumps/hoses/tubes and cylinders. One idea i came up with was when i re-attached all the hoses and the lift cylinders is to fill the oil tank then pull the rods on the lift arms out and activate the pedal (this requires 2 people). It will draw up oil from the tank, i did it back and forth a few times full stroke to try and get as much oil in as possible. I even noticed that rolling the machine around it would get stiff from the motors filling with oil too. Started it up and i had instant hydraulics available, full of air but it shows the oil made it to the pump. Just something others may find useful. [/QUOTE]
