Current job on my 2015 Ecodiesel - Tone Ring and Crankshaft Position sensor replacement (210k Miles)
After remounting the transmission to the engine, I'm going through the installation of the torque converter bolts (through the hole for the starter) that mount the flex plate to the torque converter I have successfully installed and torqued (31 ft lbs) 5 of the 6 bolts.
Issue - 1 of the 5 bolts seems to be stripped in that I, as my picture shows, have gotten the bolt fully seated but cannot bring the torque up to 31 ft lbs. It is pretty tight but when I apply the torque wrench it will not click. I have stepped it up from 20 ft lbs and it will not click at 31, it just keeps advancing an not tightening. If I apply a regular ratchet it feels quite tight...just can't get to the torque spec.
I did back the bolt out to look at the threads and they are a bit flat on the peak of the tread but not completely stripped.
Options
1. Get it in as tight as possible (20 ftlbs) and apply red Loctite be cautiously optimistic that all will be good.
2. Buy a new Torque converter bolt and tap the threads in the torque converter (I'm apprehensive on this one as I've only ever tapped threads a few times before, just have to ensure I use the right tapp).
Question
These 6 bolts that connect the flexplate to the torque converter, are they only bearing just the torque of the starter when starting the engine or the entire torque of the engine to the torque converter?
I was thinking the 8 bolts that hold the flexplate to the crankshaft that have a 90 ft lbs of torque (+30 degree turn) would be responsible for the load of transferring the engine torque to the Torque converter then to the transmission.
I really don't want to uninstall the transmission if I can help it...it's a PITA in the non-flat driveway.
thx
