Timing Chain and Sprockets

CAMSHAFT REPLACEMENT





Important:
Line up the timing marks on the camshaft sprocket and crankshaft sprocket dot to dot (figure 42). When these marks are lined up dot to dot, the number four cylinder is at top dead center of its compression stroke. The distributor rotor will need to be positioned facing the number four terminal on the distributor cap when installed.
