How do you adjust the timing on a cam sprocket?
There are several methods to adjust the valve timing: Degree bushings can be used on the cam sprocket to offset the cam locating pin. 3- or 9- keyway timing chain sets have additional keyways cut into them to index the crank sprocket.
Which is the correct timing gear for a camshaft?
Rotate the gear until the mark is at roughly 12 o’clock. Always defer to the manufacturer’s directions. With the camshaft in place, the upper timing gear should have its timing dot in the 6 o’clock position; the lower timing gear should show its zero-degree marking in the 12 o’clock position.
What are the steps to installing a camshaft?
Remove the Mass Air Flow (MAF) and Intake Air Temperature (IAT) sensor assembly, if necessary. Unbolt the radiator tray and remove it. Unbolt and detach the Manifold Air Temperature (MAT) tubes from the manifold. Remove the spark plug wires, disconnecting the wiring harness leading to the coil packs and remove the coil packs from the valve covers.
What’s the best way to turn a cam and Mark?
Rotate the cam and mark Top Dead Center (TDC). Turn the camshaft wheel until you see the V-shaped timing mark at the top. If these timing marks are not aligned properly during assembly, the camshaft will be out of phase with the crankshaft and the valves may be damaged if they strike the pistons.

What’s the best way to install a camshaft?
Using your ratchet and socket, remove the center bolt on the camshaft gear and remove the gear from the camshaft. Step 16: Install the camshaft gear onto the new camshaft.
