Thread locker /flywheel nessecary ?

[Dazzoman]

Hi , Im an newbee here and have a 3/4 ton 1966 GMC ( since 1980 ! ) with an 292 , muncie grannybox that finally died - 50 yrs .
I'm retrofitting an 1980's NP440 trans - only two bolt holes fit the '66 bell housing . (For the other side we are making an strap/bracket more later on that ).
On flywheel shall I use the star washers and some red loctite on the flywheel bolts ?

Appears to be #60 you can use red loctite I always replace what ever type lock washer OEM used oil the bolts and torque I have never used loctite on flywheel bolts and have NEVER had any problems

If it makes you feel safer use the star washers with blue loctite. I wouldn't use red.

New bolts and torque them to spec. Never had a problem. Maybe just a tiny drop of blue thread locker.

I like your answer, jtrichard . Oil on the threads gives a more accurate torque , allowing the bolt to stretch a few thousands . No need for any liquid thread lockers.
