Setting Camshaft Timing

Tools Required

1. J 39946 Crankshaft Rotation Socket. See «Special Tools»(/cadillac/dts/i-2005-2011/remont/mechanical/#engine-mechanical-46l-1-of-5__special-tools) .
2. J 44214 Flywheel Holder. See «Special Tools»(/cadillac/dts/i-2005-2011/remont/mechanical/#engine-mechanical-46l-1-of-5__special-tools) .

Setting the camshaft timing is necessary whenever the camshaft 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 be observed since one crankshaft rotation will not provide conditions where correct timing can be confirmed.

The camshafts and crankshaft events are correctly timed when the relationships shown exist. The following procedure explains how to establish this condition. Correct timing exists when the crank sprocket and the intermediate shaft sprocket have their timing marks aligned and all four camshaft drive pins are perpendicular (90 degrees) to the cylinder head surface.

Time Set Procedure

1. Remove the following components for access: The left camshaft cover. Refer to «Camshaft Cover Replacement - Left Side»(/cadillac/dts/i-2005-2011/remont/mechanical/#engine-mechanical-46l-2-of-5__camshaft-cover-replacement-left-side) . The right camshaft cover.

Refer to «Engine Front Cover Replacement»(/cadillac/dts/i-2005-2011/remont/mechanical/#engine-mechanical-46l-2-of-5) . The three chain tensioners. Refer to «Secondary Camshaft Drive Chain Tensioner Replacement - Left Side»(/cadillac/dts/i-2005-2011/remont/mechanical/#engine-mechanical-46l-2-of-5) , «Secondary Camshaft Drive Chain Tensioner Replacement - Right Side»(/cadillac/dts/i-2005-2011/remont/mechanical/#engine-mechanical-46l-2-of-5) , «Primary Camshaft Drive Chain Tensioner Replacement»(/cadillac/dts/i-2005-2011/remont/mechanical/#engine-mechanical-46l-2-of-5) (the tensioners may be in their installed positions but must be fully retracted).

4. Install the crankshaft and the intermediate shaft sprockets to the primary drive chain with their timing marks adjacent to each other.
5. Install the crank and intermediate sprocket assembly (4) over their respective shafts.
6. Rotate the crankshaft (2) as necessary to engage the crankshaft key (1) in the sprocket without changing the relationship of the timing marks to each other. Use the J 39946 to rotate the crankshaft (2). See «Special Tools»(/cadillac/dts/i-2005-2011/remont/mechanical/#engine-mechanical-46l-1-of-5__special-tools) .
