- Position the corresponding cam head vertically against the rocker arm.
- Using the handle of the hammer, press the rocker. If the ball jack bolt drops too quickly compared to other ball jack bolts, the hydraulic valve clearance compensator must be replaced.
- Try to move the rocker by hand. If it has play, then it is necessary to check the adjustment of the main position of the compensator.
The compensator is replaced as follows:
- Remove rocker.
- Unscrew the element using a 24 mm socket wrench.
- Lubricate the threads of the new compensator, screw it in and tighten to 60 Nm. If the compensator is tightened with a stronger torque, it may warp and be damaged.
- Install rocker arm and check basic position.
