IMPERATIVE: Respect the safety and cleanliness requirements.
IMPERATIVE: Respect the safety and cleanliness requirements specific to High pressure
Diesel injection (HDi) engines.
Additional operations.
NOTE: The piloted torque reaction rods have to be adjusted in the event of removing the fixing
yoke of the front piloted torque reaction rod (1).
WARNING: Tighten the supports of the engine/gearbox assembly prior to adjusting the rods.
Fit the supports (2)and (3), tighten the fixings:
Fit the tie-rod (5), tighten the fixings: 6,5 ± 0,6.
