Filling Chain Tensioner With Engine Oil - Mercedes-Benz 603 Service Manual

Filling chain tensioner with engine oil:

Place chain tensioner with the plunger bolt
downwards in SAE engine oil until over the collar
on the hexagon. Press plunger up to the stop
7 10 times slowly with the aid of a press or
power drill.
It should be possible to compress the chain
tensioner quite slowly, evenly and with little effort
after filling with oil.
Note
A revised valve disk (231) has been fitted in the
chain tensioner in order to avoid peak pressures
of the chain tensioner on the tensioner rail.
