Apply engine oil to all cam parts and journals.
If a new camshaft is to be used, apply a thin coat of molybdenum disulfide grease to the cam surfaces.
Note. The exhaust camshaft has a 117 EX mark [A] and the inlet camshaft has a 117 IN mark [В]. Be careful not to mix up these shafts.
Position the crankshaft at #1, 4 piston TDC.
Pull the tension side (exhaust side) [A] of the chain taut to install the chain.
Engage the camshaft chain with the camshaft sprockets so that the timing marks on the sprockets are positioned as shown.
The timing marks of #1, 4 must be aligned with the lower surface of crankcase of rear side [Е].
The timing marks must be aligned with the cylinder head upper surface [В].
