what is the torque on the fat *** nut?

 

It's about 90-95 lbs.
Use some Loc-tite on the threads

 

thanx the book dosent say and i did a search but nothing only how to get the thing off that was fun.

 

No, its way more then 90-95lbs. Its 290-360 ft-lbs. And thats according to the Mazda factory service manual.

 

What?? Eccentric Shaft Bolt. Not Flywheel Nut.

 

Just curious, why are you asking? If you are planning on removing the bolt to change the thermo pellet, you need to take a little precaution. Anyway, just wondering.

 

He said fat *** nut!

 

NEGATIVE~!

The E-shaft is approx 90-100 Ft Lbs.

The only reason its so hard to get off, is the sheer amount of lock-tite used on it.

so, which is right? someone told me that is about over 300 ft/lb. I even broke my ratch while using extension bar. damn it

 

E-shaft bolt (19mm) is about 90-95-100 lbs. (take your choice)
Flywheel nut (2 5/8") 290-350 lbs. (bitch to take off)

 

I got my flywheel and flywheel nut off, but having problem to take out the e-shaft bolt. usually, we can rotate the rotor with 19mm on e-shaft bolt, but I couldn't turn it at all, after few turns. I even broke my ratch. it seems like engine locked up or something?

weird

 

It's around 100ft-lb.
There is a LOT more threadlocker on the threads on this stupid bolt, thus you have a lot more trouble getting this stupid bolt off.&nbsp The Flywheels nut will have, maybe, 1/4" of thread with threadlocker; the e-shaft bolt has like over an inch covered with threadlocker.

From the S5 FSM

 

350 foot pounds. Basically a 175 pound man standing on the end of a two foot flywheel nut wrench.

 

and whats the calculation for a 300 lb man....

 

In my case, have whoever is at home and have them stand on the engine stand while you put your weight on the extension bar. An impact does *NOT* work unless you have one of those 500ft lbs woozies.

 

A 300 pound man would need to stand 1.16 feet away from the center of the flywheel nut wrench for 350 foot pounds torque on the nut.
