Thanks for writing Bentley Publishers. You will need lots of timing tools to remove the VANOS and sprockets, see page 117-27 to get a sense of the job. Assuming you have theses tools, and once the sprockets are off, the only other tool you will need is the jig to slowly relieve the valve spring tension once the cam caps are removed. I have attached a picture of this tool. I would be glad to send you this procedure if you'd like. The tool list can be quite expensive.
Hope this helps,
p.s. please send me an email address if you would like the procedure.
The factory list the following preliminary tasks for removing the crank:
· Removing cylinder head
· Removing lower timing case cover
· Removing all pistons
· Remove end cover at rear; this operation is described in the section Replacing crankshaft radial seal.
Since not many of our customers remove their crankshafts, we no longer include this info. I am happy to send you the tightening torques for the con rods and main bearing caps. Again, please provide an email address with your needs.
