The parts trade calls it several things at once: power take-off, PTO group, pump coupling, bearing housing or pump drive group. It is not a pump and not a motor, and when its bearings or gear wear, the symptoms look like a hydraulic failure while the cause is mechanical drive loss.This section covers replacement <strong>pump drive housings and PTO assemblies for Volvo EC excavators<\/strong>, including the 11128611 and 15054375 groups.
