If it's anything like the US PD engines, the hydraulic lifters automatically adjust. Make sure the adjusting block is secure and square.

The securing bolts are always replace bolts.

To adjust the adjuster nut, you have to use a dial gauge and measure when the roller of the rocker arm is at the highest point. Turn the adjustment screw to the stop and then loosen it 225 degrees. Hold the screw and tighten the lock nut to 30 Nm (22 ft-lb).
