Camshaft runout limit
0.030 mm (0.0012 in)
4. Measure:
• Camshaft-journal-to-camshaft-cap clearance
Out of specification Measure the camshaft
journal diameter.

c. Install the dowel pins and camshaft caps.
TIP
• When tightening the camshaft cap, tighten the
four bolts on the both ends of the cap tempo-
rarily to lower the entire cap, while paying at-
tention not to twist the dowel pins and camshaft
journal. After the camshaft cap touches the cyl-
inder head, tighten the two bolts in the middle
to the specified torque and then the remaining
four bolts to the specified torque.
• To prevent the camshaft cap from cracking,
tighten the camshaft cap carefully by tapping
the camshaft using a soft-face hammer (both
for temporary and final tightening).
• Do not turn the camshaft when measuring the
camshaft journal-to-camshaft cap clearance
with the Plastigauge®.
