URGENT, help needed - 93 VW GOLF Diesel, crankshaft problem

I had a friend this happened to on a dasher. He took it appart and had a machine shop weld up then remachine it but that failed (didn't tighten the bolt enough). Then he got a new timing belt sprocket and key, approximated the correct position then drilled a hole into the assemblie midway between the two pieces (half in the crankshft/half in the sproket), put in a piece of the solid part of the drill in the hole and put the bolt on to the correct tightness and then drove it it for another 100k miles. Any varience of the pulley to crank can be corrected by timing the cam at it's pulley (it's not keyed) and moving the pump in it's bracket. You've got nothing to loose because the crank is already shot, the only totally correct way is to replace it.

Roughly two years ago, I took my 95 Golf TD into an independant mechanic for a timing belt change. They recommended the insertion of a dowel pin (steel) into the crankshaft and the pulley. This helps support the keyway. They indicated it is a common failure on the AAZ code Turbo Diesel engine.

I don't know if this will work on a car that already has a buggered up keyway however.

The shop was called Competition Motors and they are located in Belleville, Ontario, if you are anywhere near them. They were great to me.
