  Q: How do you remove and install the timing chain and Sprocket on Oldsmobile Omega?

  A: If an engine has been removed from the car, some of the procedures described below should be ignored as well. First of all, you should degrade the torsional damper and the crankcase cover. Next, rotate the engine until that mark on the sprockets matches the other so that both sprockets and the chain cannot be removed from the engine in the wrong position. Then, take out the three camshaft sprocket retaining bolts and raise the camshaft sprocket and the timing chain up from the front of the engine with a tap of a soft-faced mallet if require. In the case when the crankcase sprocket has to be removed, use a puller which is designated for such operations. Fit the crankshaft sprocket to the crankshaft with a bolt and washer of the puller set. Next drop in the timing chain onto the camshaft sprocket with the slack downwards over the crankshaft sprocket. Slide the chain over the crankshaft sprocket, then bring the camshaft sprocket home with the three screws on the front, using a lot of care that you do not hammer since you can knock the freeze plug at the back of the engine. After the chain and both the sprockets have been fitted, ensure that the marks on the two sprockets coincide but if they do not, then the camshaft sprocket should be removed again to facilitate the alignment of marks. Last but not the least, apply the engine oil on the chain and put back all the parts in reverse manner that they were dismantled.
