Installation
The camshaft is installed in the reverse order, taking into account the following:
All removed elements must be installed in their original places.
Do not mix up camshafts when installing.
The intake camshaft has a slot at the end, but the exhaust camshaft does not.
Attention: The groove is designed to drive the camshaft position sensor.
When installing the bearing caps, do not confuse the caps (install according to identification marks).
Attention: The intake camshaft is marked L and the exhaust camshaft is marked R.
Check the ease of rotation of the camshafts.
Before installing rocker arms (rockers) check the video (1) and friction surface (2) for wear and damage. Replace rocker if necessary (rocker).
Before tightening the camshaft bearing caps, orient the camshafts correctly so that the dowel pins are vertical.
Tighten the camshaft bearing caps in the sequence shown in the figure in 2-3 steps. Maximum tightening torque 25 Nm.
