– Insert exhaust camshaft adjuster into camshaft roller chain
with tooth on marking “32A” so that the previously counted 16
rollers lie precisely between marking “24E” and “32A”, and
markings align.
– It must be possible to easily position the exhaust camshaft
adjuster onto the exhaust camshaft and tighten it hand-tight.
– Check the position of both camshaft adjusters again to ensure
the setting is correct.
– Remove camshaft bar - T10068 A- .
Note
So that the camshaft roller chain does not jump a tooth when the
crankshaft is turned, the tensioning rail must be pressed against
the camshaft roller chain by hand in place of the chain tensioner.
– Turn crankshaft two full turns in direction of engine rotation
and check valve timing
⇒ page 56
.
If the markings align:
– Hold camshaft which is to be tightened using a 32 mm open-
end spanner -arrow-.
Note
Camshaft bar - T10068 A- must be removed while this is done.
– Tighten securing bolts of inlet and exhaust camshaft adjusters
to 60 Nm + 90° (
1
/4 turn) further.
