Trying to find bypass valve. Would it be on the top, bottom, or side of pump. From the picture of the pump can you tell if it is a M44 or M46 servo assisted or non servo?
Is it possible that both motors are weak ( seals) because it will roll when not running or is it something before the motors as it seem to affect both. After starting I get a hydraulic alarm on the BOSS system and it shuts down. I filled the h fluid up to the dip stick level.
I just bought a used 863 with no history. 4800 hours. The engine runs fine and the the lift hydraulics react quickly and seems to have good power.
The drive seems very week with no power at idle and a little movement at full throttle. I’m thinking it might be the drive motors, as I understand...
