			*BA01.60-B-1003-01B
			*407589006300
3	Start the adjustment following the firing order	Turn the crankshaft, in the running direction, until the first cylinder piston reaches exactly the TDC. To locate the exact TDC, make the flywheel marking OT coincide with adjustment point (A).	AH05.30-B-1000-01B
4	Check the valve clearance (arrow) and adjust if necessary	 The value to be confirmed is valid only in the cases of valve play verification. To carry out play adjustment, consider “adjustment value”.	AP05.30-B-0560-01C
