Ty straps?
That is bizarre. Maybe before you weld them try the stock balancer, but really cant see how that would fix anything, seems like tons of other stuff would come loose, or other members thought would have issues. Second thought, weld them.
+1000 on the safety wire. If you safety wire them and it's breaking through the .032 or .040 wire you most likely will use, then it's bc of devil magic and the converter just wants to never ever be in your car.
Or get extra long bolts that go through the flywheel and put steel locknuts on the other side.
I don't see ty straps fixing that, weld em.
Is it possible that the rotating assembly is that out of balance? I know that's a long shot, and probably not the case. I guess I lean towards the balancer as well.
aaand the converter bolts backed out. wtf.
I'm lost. two different converters, two different transmissions, had the dowel pin issue but that was resolved. car still hasn't had but maybe 30 or 40 miles put on it since then, loctite with new converter bolts, sitting in the driveway in neutral playing with the launch and boost control stuff (which, frustratingly enough, also isn't working) when, rev clatter clatter clatter clatter. hm. key off, reach under, shake converter, clank clank clank. ****.
I've tried: loc-tite red (the make it almost ****ing impossible to get the bolts out stuff) with stage 8 bolts, after putting tabs on another flexplate, whatever the issue is it was enough to round off the lock tabs on the stage 8's and loosen them up; I've tried various combinations of stock fasteners and profanity to no avail, figured out the dowel pin missing back when the engine went into the car in sept, and thought surely that was the end of the issue... it all lines up the way it should when it's going together, I've put more force on these bolts than I did even on the 940's converter bolts, and no problems with that thing at all.
come to think of it, when I ran an aw71 behind this engine pre-totalus-90-us, bolts coming loose was never an issue there either.
I still have the billet crank pulley on the front that I can ditch (I don't need it for the trigger wheel anymore), and it's a 2.5 vs the 940 being a 2.3, but I mean ****.. wtf.
yeah I may do that as well. it's.. beyond frustrating to have a singular issue continue to crop up.
i've already given you the answer many of times. this just comes down to laziness.
well that just means you never fixed it,,, time to quit bitchin' and start fixin'
the very last time this crept up it was discovered that a dowel pin was missing from the block. that was resolved, the fasteners were replaced as was the flexplate.
clearly.
so we've reached this conclusion:
replace crank pulley
drill out to M25's
seam weld bolts to flexplate
?
apply fire to chassis.
profit.
but seriously.. this time it's going to be tack and pulley, and when I have the engine/trans out for the shell swap in a few months I'll install the new converter adapter plate with larger hardware, red loctite, nordloc washers, and maybe even safety wire(although I doubt the plate is the issue). I say maybe on the safety wire only because I'm struggling a little with how I'll go about doing that and having clearance. I reckon as long as I keep it at or below the level of the bolt heads it should be fine.
does this sound like a reasonable plan of action? Have I left something out?
billet alu underdrive pulley.
when I re-tap it I'd like to make sure I keep the steel inserts (well, in this case, would need to replace with the appropriate size and pitch), are such available in a slightly undersized fit/will the m12x1.0 inserts work as intended in a slightly undersized hole? (two ways to ask the same question)
yep. I'll see if I have an old stock one laying around or if I'll have to order me one up.
are you suggesting aftermarket rods and pistons alter the weight of the rotating assembly? that's absurd sir.
I've heard and seen good and bad from the dampers, hopefully I don't have to go that route. I'd think if it was legitimately a vibration loosening things up that I'd see other things get loose too even if at a greater infrequency yea?
weak ass wire hanging on for dear life to those torque converter bolts.
