Camshafts cylinder front
– Insert the two camshafts marked "in fr" (front intake camshaft) and
"ex fr" (front exhaust camshaft) into the bearings without tilting. The
marks on the camshaft gears must coincide with the cylinder head
surface (see illustrations).
NOTE:
– The same camshaft gears are used in both cylinders but they have
marks for cylinder rear and front. Use the camshaft gear marked
with a cross for cylinder rear and the camshaft gear marked with a
circle
for cylinder front.

mounted on the same cylinder head.
– Place plastigauge measuring strips
camshaft bearing positions.
– Carefully mount the camshaft bearing bridge and tighten the bolts in
the camshaft bearing bridge to 10 Nm (M8) in the first stage.
– Tighten to 18 Nm (M8) and 10 Nm (M6) in the second stage.

OTHERWISE THE BEARING BRIDGE WILL BREAK
NOTE: do not turn the camshafts.
– Remove the camshaft bearing bridge again and compare the width
of the plastigauge measuring strip
packing. The width of the plastiguage measuring strip is equivalent
to the bearing clearance.
Camshaft bearing clearance: 0.020 mm – 0.061 mm
