Installation Of Camshaft Timing Pin (1) Timing pin. (4) Camshaft.
Install the camshaft timing pin (1) through the timing pin hole and into the hole in the camshaft (4). In order for the engine to be timed correctly, the camshaft timing pin must fit into the hole in the camshaft.
If the timing pin (1) cannot be installed into the hole in the camshaft, the engine is not in time and the camshaft position must be adjusted. Refer to "Timing Adjustment Of The Camshaft".Timing Adjustment Of The Camshaft
Note: Before you make any timing adjustments, the timing must be checked in order to determine whether any adjustment is necessary. Refer to the section "Camshaft Timing Check " for this procedure.If the "Camshaft Timing Check " procedure indicates that the camshaft is not in time with the crankshaft, the camshaft drive gear must be removed and the camshaft must be rotated. Steps 1 through 7 should be used if adjustment of the camshaft is necessary.
Put the No. 1 cylinder in the Top Center Position of the compression stroke and install the crankshaft timing pin. Remove all of the valve covers.
