If the valves required to be rocking are
closed, rotate the engine one revolution,
which will bring these valves to the rocking
position.
The flywheel housing has an inspection hole
directly below the 'B' bank turbocharger(s)
through which the flywheel markings may be
seen to line up with the pointer set in the
flywheel housing Fig. 51.
The flywheel is marked as follows:-

EQUALISING THE BRIDGE PIECES
Having rotated the engine to the correct
position see the table on page 56, check that
t
he inlet and exhaust rockers to be adjusted
have clearance before continuing with the
next operation. Loosen the locknut on each
bridge piece adjuster, screw the adjuster out
until the fixed side of the bridge piece rests
on its valve, hold the top edge of the bridge
piece down with one hand Fig. 52, then
s
crew the adjuster down until you feel it
touch the valve, thereby equalising valve lift.
Tighten the lock nut without moving the
adjuster.
