sembly tip with liquid gasket (LOCTITE 242 or
equivalent) and insert and screw the tip from
the front side of the PTO, then tighten it at a
specified torque.

• When tightening the inner rod assembly, insert

a Phillips screwdriver (large) in the control ca-
ble connector groove, press it so that the spool
valve will not rotate, then apply a wrench to the
stopper adapter on the oil pump side to tighten
it. (Besides, the three-rotation dump truck is in
contrast with this.)
