Check the cams (1) for broken material, signs of distor-
tion or wear and, where necessary, replace the cam-
shaft.
Measure the play of the camshafts:
Place the camshafts in the head.
Apply a plastic gauge (2) on the bearing housings of the
camshafts.
Apply the U bolts according to which shaft they are as-
signed to and fasten them with the M6 T.C.E.I. screws.
Driving torque: 10 Nm (1.0 kgm).
Remove the T.C.E.I. screws and the U bolts.
Measure the maximum width of the pressed plastic
gauge with the corresponding graduated scale (3).
Wear limit: max. 0.060 mm.
If the wear limit is exceeded, the bush housings on the
camshafts and on the head must be measured, and the
worn part replaced.
– Camshaft bush housings:
wear limit (4): min. Ø 23.950 mm;
– Head bush housings:

Insert the intake and exhaust camshafts in the respec-
tive housings in the head and measure the end play
with a comparator.
– End play of the camshafts:
wear limit: max. 0.40 mm.
If the wear limit is exceeded, the axial contact surfaces,
both of the camshafts and in the head, must be meas-
ured and the worn part replaced.
