Hello,<br /><br />I wanted to rebuild my old '76 Merc 500. Now the crankshaft was damaged at one of the rod bearings and i thought i could use the other one i still have in my second engine. But there, the crankshaft ist badly damaged at the lower oil seal 
<br /><br />Now just out of curiosity, what can cause the following things??<br /><br /><br />This is, the first one, where the needles of the rod bearing should be.<br /><br />
<br /><br />And here is the second one. The funny thing is, the seal looks like in perfect condition. I just don't understand it. Well, it seems it's over now. A new crankshaft for a '76 Merc isn't worth the effort.<br /><br />
<br /><br />thanks<br />martin
