Removal
PERFORMANCE ORDER
1. Uncover a head of cylinders.
2. Dress special brackets of MB998443-01 on hydropushers. Release bolts of covers of necks of a cam-shaft, slightly pressing on yokes.
3. Turn out bolts of covers in the direction from a forward cover to back, at the same time ask the assistant to hold a cam-shaft reliably. It is impossible to assume that the belt tension sharply increased at a cam-shaft exit from support (otherwise it is necessary to reinstall a cam-shaft and a belt).

Grease all details. At installation of rollers the assistant has to hold a cam-shaft.
