Pay attention to the following details.
Apply engine oil on rocker arm shaft.
IMPORTANT: The rocker arm shaft can only be in-

shaft as well as camshaft has to be positioned
with their locking pins when the piston of cylin-
der no. 3 is on ignition TDC. Refer to CYLINDER
BLOCK section for crankshaft and the following
for the camshaft locking.
Use camshaft locking tool (P/N 529 035 839).
