Fully

timing
chain tensioner.
e
Info
This
requires
considerable force since the oil has to 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
piston
of the
timing
chain tensioner. This should
ensure
that when
pushed
down,
the
piston
does not
fully
withdraw.

Info
This
position
is
necessary
for installation.
If
the
timing
chain tensioner is
now
pressed in
once
more
(while it is installed) and then pulled
out
no more
than
halfway (preventing
it from
coming
out
fully),
the
latching system
locks and the
timing
chain tensioner
can
no
longer
be
compacted;
this function is
necessary
to
ensure
sufficient tension of the
timing chain,
even
at
low oil pressure.
