Rocker Arm Shaft Assembly: Installation

- Coat rocker arm shaft, rocker arms and valve stems with engine oil. Install rocker arm shaft assembly on cylinder head. Apply silicone gasket material to No. 1 rocker arm bracket mounting surface on cylinder head.
- Starting with inner nuts and working outward, tighten brackets in progressive steps. See Figure. Adjust valve clearance and install valve cover.
