Inspection Procedure

1. Position the NO.1 cylinder piston to ATDC 20° by turning

the crankshaft

Notice

When the ATDC 20° mark on vibration damper is aligned
with timing gear case cover, the  intake and exhaust cam of
cylinder will make the slope to the center and will face up.
In this way, the insert hole in NO.1 and NO.4 camshaft
bearing cap will match in line with the flange hole for
camshaft sprocket.

2. Check the timing as below procedure;

-

Check if the insert pin (111 589 03 15 00) can be inserted
into the NO.1 and NO.4 bearing cap hole.

-

At this condition, check if the ATDC 20° mark on vibration
damper aligns with the marker on the timing gear case.
