Define a backlash between cams and roller levers.

Fig. 2.531. Check of a hydraulic pusher


Press by means of a screw-driver the roller lever downwards (fig. 2.531).
If between a cam-shaft and the roller lever enters probe in the thickness of 0,20 mm, replace a hydraulic pusher, having removed for this purpose the roller lever.
