Use a 17 mm hexagon to unscrew the plug of the chain tensioner with an internal hexagon (see fig. 84) and remove the spring.
Insert a 10 mm hexagon into the chain tensioner and pull out the chain tensioner by turning to the right.
After removing the tensioner, disassemble it and then put the pusher in the mounting position "A" (see fig. 85 and 86).

When loosening the chain tension with the tensioner installed, for example, when removing the camshaft sprockets, remove the tensioner and put the pusher in the installation position. When replacing the tensioner, install with the pusher assembly.
Install the chain tensioner in reverse order and tighten the plug with a new O-ring to 50 Nm.
