18.4.34 Preparing the timing chain tensioner for installation
200171-10
–
Press the timing chain tensioner together completely.
Info
This requires some force, as the oil must be pressed out.
–
Release the timing chain tensioner.
Without pressure, the timing chain tensioner expands fully.

–
Place two compensating disks or similar aids next to the timing chain tensioner
piston. This ensures that, when pressed in, the piston cannot go in all the way.
Guideline
Thickness of the compensating disks
2… 2.5 mm (0.08… 0.098 in)
–
Release the timing chain tensioner.
The detent mechanism engages and the piston remains in place.
Final position of the piston after
engagement
3 mm (0.12 in)
Info
This position is necessary for installation.
If the timing chain tensioner is now pressed again and is only extended a
maximum of half way (it is prevented from extending completely). This locks
the detent mechanism and the timing chain tensioner can no longer be
squeezed together. This function is necessary in order to ensure sufficient
timing chain tension even at low oil pressures.
