ARMS-ROCKER
DESCRIPTION
The rocker arms (1) are made of stamped steel and serviced as an assembly along with the lifter.
The rocker arms (1) are used as a link between the camshaft and valves. As the camshaft rotates, the lobes of the camshafts apply downward pressure on the rocker arms (1). This pressure is then applied to the hydraulic lifter (2) which opens the valve.
REMOVAL
CAUTION: Before removing the cylinder head cover/intake manifold (2) the engine must rotated to 90° after TDC to assure proper alignment of the engine timing components. Failure to do so could result in valve and/or piston damage during reassembly. (Refer to 9 - ENGINE/VALVE TIMING - STANDARD PROCEDURE)
1. Disconnect negative battery cable.
2. Rotate the crankshaft to 90 degrees ATDC (Refer to 9 - ENGINE/VALVE TIMING - STANDARD PROCEDURE).
3. Remove the camshafts. (Refer to 9 - ENGINE/CYLINDER HEAD/CAMSHAFT(S) - REMOVAL)
4. Remove rocker arms (1) and lifters (2).
