Removing Camshafts

Information

Always counter camshafts at the hexagon because the camshaft bar can break!

Information

The numbers of the bearing covers on the outlet camshaft 3 are even numbers, counting from the timing chain.
The numbers of the bearing covers on the intake camshaft 1 are uneven numbers, counting from the timing chain.
The bearing cover numbers can be read from the intake side.
Corners of the bearing covers are facing outwards.
Bearing covers no. 7 and 8 are thrust bearings and guide bearings.
