my flywheel keeps comeing loose

[Poodles]

Yep, different parts in the EPC... Auto ones are probably shorter.

I have also reused flywheel bolts with no ill effects. As poodle said, they should not have any problems as long as they were not over torqued. Just make sure you put locktite on them and torque them with a GOOD torque wrench.

Although some might think this is a dumb question and no one asked it, but which bolts did you use? The manual flywheel ones, and not the one that were in your motor as an auto correct?

i used the manual trans bolts. i did notice that the car they were on that they were really tight and we had to use a breaker bar to get them off.

so now that you have all of this information would you fork over the few extra dollars for new bolts or reuse the old ones? :biglaugh:

 

[adampecush]

Older fasteners if in good shape have already been heat cycled and burnished giving better torque readings, no reason to replace unless they're torque to yield fasteners or you're upgrading.

this is not true at all.

Manufacturer torque specs are based upon new fasteners, inserted into clean female threads. New fasteners had a consistent, predictable surface finish. As torque specifications are based solely on the predicted resistace within the threaded region and under the head of the bolt, any wearing of the threads, applied lubricant, or debris changes the "torque resistance" of the bolt, resulting in improper preload.

I believe ARP ask for user to use moly, but thats only to ensure accuracy of the torque. Perhaps from all that is mentioned here red loctite might replace my moly this time.

 

[adampecush]

if the bolt is properly preloaded (and the thread form is intact), it will not back out. If ARP recommends moly lube with a specific torque value, listen to them, they've done their research.

loctite does not have the same lubricating characteristics as moly lube, so the torque required to achieve the same preload will be different.

Very very true... To add to this, make sure that your torque wrench is accurate... You might want to take it in and have it calibrated...

Reusing flywheel bolts is like reusing a condom, you just don't do it.

Damn, no wonder why I have so many kids..... lol

:word8kn: for the amount of time it takes to get to the friggan things you use new ones. not gamble with used.

 

[YotaRob]

loctite is used to keep oil from leaking from the holes also. What are you using to torque em down? and how much, PFT?

 

[Poodles]

Oil won't leak through on a 7M, that's on the JZ's

 

[YotaRob]

Yeah it can, I have done it before. You just dont like JZ's do you.:nono:

 

[Zumtizzle]

^Nah they don't.

 

[tlo86]

^Nah they don't.

mightve been a rear main hehe

 

[Poodles]

No, really, I have a 7M crank in my garage I could take pics of...

The holes are blind on the 7M and go all the way through on the JZ's

 

[IJ.]

Blind x 3

 

[YotaRob]

Nevermind, I am losing my mind.:aigoroceed.

but in the heat of the moment?
