I replaced the water pump on my 1989 740 GL (16 Valve). I thought I had dropped the nut on the water pump that is over the lower timing belt cover into the cover. I used the "rope trick" to lossened the bolt that holds the crankshaft pulley in place enough to allow the nut to fall out of the bottom of the lower timing belt cover - it wasn't there. I then tightened the nut on the crankshaft and torqued it to 44 ft/lbs + an additional 60 degrees.

Now the crankshaft pulley woobles - I just pulled it foward about 1/2 inch perhaps a much as 3/4 of an inch. Could this cause the wobble in the pulley? How do I correct it.

Thanks in advance for your help.
