Bolt from the blue.
15 March 2013
So I was 95% finished with the reassembly of the motor when I mounted the flywheel and while torquing the last six bolts one of them stripped. Arghhhh!!!!!
The torque was right by the book but the bolt was tired. Once I got it out (no fun) I could examine the others. They all were stretched and ready to go. Have to be replaced. The pan and block make it impossible to remove the bolts from the crankshaft flange - thus removing the oil pan. This meant putting the motor back on the assembly stand, rolling it over after removing the newly mounted fuel injection pump, and removing the oil pan once again. This took some work as it had been all sealed down ready to run. Now it was a cleanup problem. Mercedes wants $125 a bolt and nut. That's ONE bolt folks. Thus my machinist buddy and I are making them. This is a pic of a grade 8 (hard steel) US 1/2" bolt on the lathe being turned down to 10mm. Then we have to cut it shorter and thread it. That's a part I'm worried about.
