No loctite was put on the fly wheel nut.....
I helped my friend to assemble his 3rd gen engine, but I was not there when he installed the flywheel and nut. He did not loctite the nut. ?????? He says he forgot to pick it up before the assembly, but has gone without it in the past and has not had a problem. He says because he uses a 3/4 impact gun to install the nut, its on real good. I also recently rebuilt my spare engine but used a 1/2 inch gun and loctite, its stated right there in the FSM.
My question is has anyone gotten away without loctite on the flywheel nut on a high HP engine. Does he have a chance? |
Loctite is not required. Proper torque is the only requirement. I have never used loctite.

"it's on real good" is NOT consider a torque sequence/spec =). -AzEKnightz |
What torque wrench are you using? Mine has the "it's on real good" setting. Don't they all???
Agreed torque to the proper spec and all is good. |
Yea im pretty sure the MULTI HUNDRED lb/ft is more than enough...
|
Spec is 300 ft lbs don't assume because it's impacted on it's tight, get a torque wrench.
|
I use a breaker bar with a cheater bar. I never relied on an impact for something like that, but you might be ok with that 3/4." Those things are beasts.
|
Torque is 350lbs. Grab a 3.5ft breaker bar and put 100lbs of pressure on the end of it. That equals 350lbs. No torque wrench needed! ;)

you dont need to put any lock-tite on the flywheel side. Reason being as the engine spins it would "tighten" it rather then "loosen" it, based on the direction of rotation... but I highly doubt it would come off regardless of direction, but I do how ever locktite the front E shaft bolt, as it sees a pressurized area of the engine... and I would rather be safe then sorry on that bolt....

Sorry your wrong about the direction of rotation. The nut tightens in the same direction the engine rotates. The threads are normal and not reversed. So it can spin off if not torqued correctly. That's why all circular saws have reverse threads to prevent this from happening.

it is fine
you are overthinking it if you are bringing "engine torque tightens it" in the equation.... what happens when you shift? torque it right, it is probably fine.... factory also say to use locktite.... you probably should have used it... remember chrysler putting on reverse threaded lugnuts because they have that retarded mentality (like yours) of it self tighteing.... and self loosening? |
Nice cheap solution t-von!

how can you say this when the engine ( looking at it from the back ) rotates counter clockwise while the nut tightens clockwise?

Sorry I confused myself during the explanation. LOL! I just re-read what I wrote and was like WTF!!! But yea the nut can tighten as the engine rotates in it's normal direction and CAN'T back off. |
Honestly wtf has a torque wrench that does 300 + i myself only have a 1/2 drive witch does not go over 250 crank that bitch on and dont worry
