regulator torque JAGUAR X308 1998 2.G User Guide

Installation


6. Remove the nine screws from th e pressure regulator / solenoid
retaining plate.

7. Remove the relevant pressure regulator.

1. Installation is the reverse of the removal procedure, noting
that a new pressure regulator 'O' ring MUST be used.
Fit the nine screws securing the pressure regulator /
solenoid retaining plate and ti ghten to the specified torque
figure.
2. Refit the RH rear valve body secu ring screws and tighten to the
specified torque figure.
