I'm looking for you guys to confirm that, thanks to being a bonehead, I stripped a bolt and possibly also a bolt hole in the balancer hub assembly.
My RMW has the mechanical fan. Therefore, it has the extra pulley up front. Please excuse my large zip ties; that's what I was using to keep the pulleys from turning as I torqued the bolts.
[You must be registered and logged in to see this link.]I was using this diagram in the FSM to guide me as far as the names of the three types of bolts I had; the correct name would allow me to find the correct torque values.
[You must be registered and logged in to see this link.]I have three sizes of bolts; one for the crank snout; three larger for the balancer assembly to crank hub, and three smaller diameter for what I now believe mate the extra pulley for the mechanical fan to the balancer assembly.
[You must be registered and logged in to see this link.]I was using the torque value of 63 ft. lbs for the smaller bolts, being confused I think by what they were in the diagram and torque chart. The first bolt kept turning with no click from the torque wrench, and I was thinking "hey, this feels like I should have enough by now." Then, I felt something give and said a few choice words. I took the bolt out and it has clearly been damaged in the part of the threads just under the head. Sorry for the blurriness in the one pic.
[You must be registered and logged in to see this link.]It's weird looking. The bolt still has threads along its entire length, but you can clearly see the threads under the head look coarse and the diameter seems smaller than on the undamaged bolt. I'm not really sure exactly what happened.
So, am I correct in assuming that there is some other portion of the FSM that covers these extra bolts and different torque numbers for cars that have the mechanical fan option?
And, am I now looking at pulling the balancer to fix the damaged hole? I assume it's damaged, since the bolt is stripped.
