Hello. My daughter's '89 B230 engine has stripped the "key" or tab in the crankshaft timing gear. This of course means the engine will run faster than the belts thereby making the alternator turn slow and not charge the battery, the power steering going out, the water pump not pumping, the engine getting hot and the entire car going nuts. My daughter somehow brought it 65 miles home like this. After ruling out the alternator and noticing all belts turning too slow compared to the engine, I figured the little tab down there in the crankshaft gear sprocket was stripped. I got the bolt out using the rope a dope trick. Easy. BUT, the pulley will not pull off so that I can get to the sprocket. Do I have to completely loosen the A/C compressor and take the belts off first. I was hoping the pulley would just pull right off when I got the bolt and retainer off. The A/C pulley adjustment on the front side is loose, but I am finding it impossible to loosen the slide bolt on the back side of the A/C mount. Is that really necessary. It is a @#%&@@!!! If I have to I will probably have to buy one of those expensive half moon curved wrenches. Any ideas. BTW, those crankshaft sprockets with the key are pricey. Whoooweee!
