	Remove
1	Remove cylinder head cover
		With CODE 494 (USA version)	AR01.20-P-5014MCU
		Except CODE 494 (USA version)	AR01.20-P-5014MCC
2	Detach right rear wheel
		With CODE 494 (USA version)	AR40.10-P-1100MCU
		Except CODE 494 (USA version)	AR40.10-P-1100MCC
	Check
3	Turn engine to top dead center position
		With CODE 494 (USA version)	AR01.10-P-1000-01MCU
		Except CODE 494 (USA version)	AR01.10-P-1000-01MCC
4	Lower vehicle with lifting platform
5	Check whether the valves of the 1st cylinder are relieved of load, if necessary continue turning engine one revolution in direction of engine rotation at the central bolt of the crankshaft pulley
6	Check valve clearance of the intake valves of the 1st and 2nd cylinder as well as the exhaust valves of the 1st and 3rd cylinder	It must be possible to insert the feeler gauge making smooth contact all round between the cam of the intake camshaft (1) or exhaust camshaft (2) and the valve tappet, if necessary determine and note the deviation.

		Valve clearance for exhaust valve	*BE05.30-P-1002-06C
		Feeler gauge	Fig 2
7	Crank engine by center bolt of crankshaft belt pulley by a further 1800 in the direction of engine rotation
8	Check valve clearance of exhaust valve of 2nd cylinder as well as the intake valve of the 3rd cylinder	It must be possible to insert the feeler gauge making smooth contact all round between the cam of the intake camshaft (1) or exhaust camshaft (2) and the valve tappet, if necessary determine and note the deviation.

	Adjust
9	Remove valve tappet of the corresponding inlet or exhaust valve
		With CODE 494 (USA version)	AR05.00-P-2310MCU
		Except CODE 494 (USA version)	AR05.00-P-2310MCC
10	Select valve tappet of appropriate thickness and install
		With CODE 494 (USA version)	AR05.00-P-2310MCU
		Except CODE 494 (USA version) The sum of the thickness of the valve tappet removed and the tolerance deviation of the valve clearance gives the thickness of the valve tappet to be installed. The dimension for the thickness of the valve tappet is located on its underside.	AR05.00-P-2310MCC
11	Recheck valve clearance and adjust if necessary
	Install
12	Attach right rear wheel
		With CODE 494 (USA version)	AR40.10-P-1100MCU
		Except CODE 494 (USA version)	AR40.10-P-1100MCC
13	Install cylinder head cover
		With CODE 494 (USA version)	AR01.20-P-5014MCU
		Except CODE 494 (USA version)	AR01.20-P-5014MCC
