♦ The locking pin -T40060- has a flat -2- which makes it eas-
ier to insert when the locating bores in the camshaft and
cylinder head are not exactly in line.
♦ The locking pin is inserted initially so that the side pin -1-
is perpendicular to the imaginary line between the locking
pin and the centre of the camshaft.
♦ To obtain the correct “TDC” position, the side pin -1- must
then be turned 90
° -arrow- so it is in line with the imaginary
line between the locking pin and the centre of the cam-
shaft.
– Check that camshafts on both cylinder heads are posi-
tioned at “TDC”.
• It should be possible to lock camshafts with locking pins
-T40060-.
• The side pin -arrow- in each locking pin -T40060- must be
in line with the imaginary line between the locking pin and
the centre of the camshaft.
