Was out in the fifteen last week and just as i am pulling back into the garage the low pedal got weird. Then i heard the tell tale sound of a fastener bouncing around inside the oil pan. Pulled the inspection cover and three of the six backing plate bolts were sitting in the filter. I had been in the habit of using loctite on them and no safety wire as it seems to cause more problems than it solves. Must have forgot the loctite this time….sure do like that filter thingy.

Do you mean the 6 bolts which attach the driven plate to the brake drum? I would not trust Loctite of any persuasion there. It likely gets too hot for Loktite, the bond of which is often indicated can be broken with heat for removal. Is there a super high temp agent they make?

Completely agree! Even if Loctite was a valid solution, at this point, you'll never get the threaded holes clean enough for the Loctite to be effective. Please use the wire.

That was a lucky catch Mark!

In response to Allan, Loctite 243 or 263 would be fine in that location. The transmission won’t get close to the temperature where either of those products starts to loosen up and your threads don’t need to be super clean either.

Use Loctite AND wire.

Eagads, loctite instead of safety wire?!
