Installing exhaust camshafts
Install the camshafts.
When installing camshafts, keep in mind that the axial clearance is very small, so the shafts must be laid in the bearing bed strictly horizontally, without distortion, in order to avoid jamming and / or damage to the shafts.
Install the rear head exhaust camshaft.
Apply a coat of engine oil to the end thrust surfaces of the camshaft.
Set the intake camshaft 90° from the position where the alignment marks on the cylinder head align (fig. 3).
Apply grease to the new oil seal.
Install the oil seal on the camshaft (fig. 4).
