Flex plate to torque convetor bolts will not stay tight.

[nujac]

On my 94 3.2l dohc trooper the flex plate to torque convetor bolts have come loose a couple of times over the last two years. I noticed they do not have lock nuts and they did not have any type of lock tight product on them. Does anyone have a fix for this problem? Also the holes on the flex plate that the bolts go through do not seem to be too loose.

Thanks for your time

if that were happening to me i'd make sure i'm getting torqued to the correct 41ftlbs and use blue loctite.

i've seen a number of posts recently it seems to me about flex plates and their bolts.
one thing -- aren't there some dowel pins in that installation? did you use them? i've read without them the flywheel/flex plate can actually selfdestruct.

The three bolts that hold the torque convetor to the flex plate do not have any dowls are places for dowls on mine. I will try using the blue lock tight this time around

thanks

Factory recommends installing new bolts when replaceing these. Are you torquing them ..... ? Seems like it was around 50 N/M...but check first. Blue loctite is removeable, I would go with 252 or similar....unless you plan on doing this again.

new bolts would be a good idea. but you *do* want any threadlocker to be the type that does allow removing in the future. blue loctite is excellent for this type of application and will keep vibrations from loosening the bolts up.

as mentioned before, make sure you torque to 41ftlbs, which means you have to keep the plate from turning as you torque.

good luck
