Work instructions

2

Remove chain tensioner complete

Installation:
Replace the entire chain tensioner.
Replace sealing ring (2).
Before installing, fill chain tensioner with engine oil. Position chain tensioner with thrust pin facing down in engine oil until it is over the collar at the hexagon. Use a press or column drill to slowly depress thrust pin fully 7 - 10 times.

After filling, it must be possible to compress the chain tensioner only quite slowly, evenly and with considerable force.
