NOTE
The exhaust camshaft has a 1001 EX mark [A] and the intake camshaft has a 3154 IN mark [B]. Be careful not to mix up these shafts.

#4 Cam Positions [A] Intake Camshaft Sprocket [B] Exhaust Camshaft Sprocket [C]
The intake camshaft sprocket and exhaust camshaft sprocket are identical
Torque - Camshaft Sprocket Bolts: 15 N·m (1.5 kgf·m, 11 ft·lb)

If a new camshaft is to be used, apply a thin coat of molybdenum disulfide grease to the cam surfaces.
NOTICE
The crankshaft may be turned while the camshafts are removed. Always pull the chain taut while turning the crankshaft. This avoids kinking the chain on the lower (crankshaft) sprocket. A kinked chain could damage both the chain and the sprocket.

The timing marks must be aligned with the cylinder head upper surface [B].
