You basically run there of getting an air lock either in a pump or motor and burning it up while the system tries to purge the air.
Think of it this way too, if you replaced caliper on a car, would you assume you had enough oil in the caliper tomake it function properly, or would you bleed the system?

I kinda hear you but that sucking device isn't going to get all the air out or
all the oil. This rebuild isn't much different than doing a oil change or replacing a pump or wheel motor. I have done them and watched many done and I have never seen anybody using a suction device. Just put oil in start it up with wheels off the ground and run it until it fixes it self. Yes there is apparently air inthe system and I don't know where it goes but the units will eventually start driving. Am I doing something really wrong?
