INSTALLATION

H4 MODEL
1) Install the oil pump to bracket.
(1) Place the oil pump bracket in a vise. Tighten the bushing using a 12.7 mm (1/2") type, 14 and 21 mm box wrench until it is in contact with the oil pump mounting surface.

CAUTION: When securing the oil pump bracket in a vice, hold the oil pump bracket with the least possible force between two pieces of wood.

2) Attach the installation bolts of the power steering pump bracket.





3) After installing the oil pump, fill the fluid while rotating the pulley by hand and bleed the air from the oil pump.

CAUTION: Always fill the oil pump with the fluid to prevent abnormal noise and seizure of the oil pump.

4) Connect the pressure hose and suction hose.
Tightening torque:
Eye bolt 40 N-m (4.1 kgf-m, 29.5 ft-lb)

CAUTION: Be careful when installing; If the hose is twisted it may come into contact with other parts.
