• Remove the chain guiding bar. Clean the surfaces of shell and camshaft and use fresh oil
for the reassembly on the bearing surfaces of camshaft and bearing shell. Remount the
bearing shell. Turn in the screws equally and fasten them with correct tightening torque.
• Tightening torque screws: 12 Nm (106 inch-Ibs.)
• Turn the engine two or three times and check the setting of the cam timing.
• (Description in the following Chapters)
Rotate the engine clockwise (when facing flight direction).
Turn the engine very carefully. If there is a stop or resistance TURN BACK and check the

• Turn the engine to top dead center (TDC) position. See Figure 85 - 113.
Misalignment can result in less power available. Duplicate inspection recommended.

• The punch marks on the timing wheels of the camshafts must be aligned as shown in
Figure 85 - 114.
• Both timing wheels contain a 6 mm hole. These holes must be on the exhaust side and
the lower edge must be aligned with the cylinder head surface. Figure 85 - 86 shows tool
AE-300-T009 placed into these holes of the timing wheels.
To ensure the correct setting of the camshafts insert tool AE-300-T009. The tool bolts must
be located at the exhaust side in contact with the cylinder head housing.
