(6)
Attach the pressure hose/tube (20) to the lower bracket with the clamps (15), the bolts (5) and the washer (10). Do not TORQUE the bolt at this time.
(7)
Install the center mount clamp (40) as follows:
(a)
Remove the bolt (25), the washer (30) and the nut (35) from the band on the center mount clamp (40).
(b)
