Mr. Gadget

In all of the 100's of motors I have built I have always used some blue locktite in the 54mm flywheel nut. In revewing the last motor I built, I am certian I forgot to do so.

So, do I rip the tranny out and reinstall the nut with blue locktite?

Car is up and running (runs real good) and has about 100 miles plus 10 hours on the motor.

thanks

my instinkt would be to leave it but thats probobly not the right one i mean the thing is on there with 600flbs. right

Its your call really. The FSM calls for some thread locker as well.

You know how the Rotor God's LOVE to find things that we think won't be a big deal and MAKE a big deal out of it don't ya?????????????? They hate me by the way....

All it will do is mess up your clutch and possibly bend the transmission input shaft if the whole flywheel comes loose. If the car is special and you like it, I would go ahead and redo the nut. If it is a beater and you don't rev it nor need it to be dependable, you could leave it alone and see what happens.

If it was my car, I would spend the 5-6 hours to r/r the trans. and redo the nut.

5-6 hours, holy crap.
I forgot my pilot bearing (I know....) in my last install, and it took me 2.5 hours total to install it- I could have done it quicker if I went hardcore on it.
I didn't use loctite either.. AND my impact gun puked out right at the end.... but it should be fine. (gulp)
Peace of mind is priceless... especially with 15 year old rx-7's at that. There are numourous other things that can (and will) go at any time.. the flywheel nut isn't one I want to worry about too!

Impact gun is cheating. Never really timed it, but you could definately redo the nut in an a night depending on your speed/obstacles.

Bambam7

No impact gun fur the tranny drop.. I meant for sintalling the flywheel nut.
For me, the lifesaver is a set of ratcheting, flexhead box wrenches. ***Awesome!!!!!*** Also a flexhead ratchet for getting the driveshaft flange nuts off. 5 minute job.

BDoty311

Yup, driveshaft would be easier with a set of those.

BTW= If you do drop the tranny, be sure to drain it BEFORE you unhook the driveshaft. Otherwise fluid will come out of the tranny and stuff gets messy really fast.

Mr. Gadget

thanks, I have done a **** load of engines, first time I made this dumb **** mistake, was hoping to avoid dropping the tranny.

But on the upside, I can take ot to the car wash and clean the crap off of it

there is no way a ratcheting box end can handle 350ft/lbs

Mr. Gadget

I think he meant they were for the drive shaft and such

BDoty311

I wanna know who actually gets out a torque wrench and makes it 350ft-lbs?

Templeswain

uh,

I would say its probably okay but, I'd hate to have your feet cut off by any detonation of the flywheel from the nut spinning off.

I'd guess you'd have to go with some crazy equation for the probability of failure.

Yeah, its probably is okay.

But.....

Mr. Gadget

I have and do every motor that is why I am pissed about the locktite.

Bro I was standing two feet down my flywheel nut wrench! 160lbs x 2ft = 320 ft*lbs, and I jumped on the bar a tad to bump it up to 350 before I called it good.

Crude as it may sound, the instructions with the Racing Beat flywheel nut wrench explicitly describe this exact method of achieving 300-350 ft*lbs when torquing the nut.

andrew lohaus

how the heck are you supposed to do it if you're under the car?

Mr. Gadget

Its hot that hard. My torque wrench has a slot for a 1" pipe and its 2' long. Out of the car - easy. In the car, easier, arms/back if it reaches against wall, feet on torque wrench, son watching dial. Legs are 10 times stronger, therefore easier than the arms. Works ever time.

Oh how I wish I had that luxury, my car was more filthy the day it broke down than any other day I've owned it.

if this was a customers car I would reccomend tearing into it and redoing the nut. If it was my car on the other hand....
