This wrench can be used to either torque main bearings or crab nuts using the same 230 Volt hydraulic pump. Both torque handles are equipped with quick disconnects for easy changeover.
There are three pressure settings on the pump (900, 1,800 and 2,400 Lb/Ft) for the crab nut application, and the unit self adjusts to 350 and 750 Lb/Ft when connected to the main bearing wrench head.
