Timing Chain: Service and Repair
Setting Camshaft Timing
SETTING CAMSHAFT TIMING
Setting camshaft timing is necessary whenever the cam drive system has been disturbed such that the relationship between any chain and sprocket has
been lost. Even when only one sprocket is involved the following procedure should he observed since one crankshaft rotation will not provide
conditions where correct timing can be confirmed.
Setting Camshaft Timing
The camshafts and crankshaft events are correctly timed when the relationships shown exists. The following procedure explains how to establish this
condition. Correct timing exits when the crank sprocket and intermediate shaft sprocket have their timing marks aligned and all four camshaft drive
pins are perpendicular (90°) to the cylinder head surface.
