Rocker Arm Assembly Installation

1. Make sure the crankshaft pulley is at top dead center (TDC). Align the TDC mark (A) on the crankshaft pulley with the pointer (B) on the chain case.

2. Insert the bolts (A) into the rocker shaft holder, then install the rocker arm assembly (B).

3. Check the alignment of the TDC marks (A) on the cam chain sprocket with the cylinder head surface.
4. Align the TDC marks (B) on the intake camshaft gear (C) and the exhaust camshaft gear (D), and install the camshafts.
5. Apply new engine oil to the bolt threads of all the camshaft holder bolts.

6. Put the camshaft holders on the cylinder head, then tighten all bolts to 22 Nm (2.2 kgf-m, 16 ft. lbs.). To prevent damaging the camshafts, tighten the bolts two turns at a time, in the sequence shown.
7. Adjust the valve clearance.
8. Install the cylinder head cover.
