I've done a good amount of searching on how to properly remove the flywheel nut, however out of all the threads I have come across the engine has either been on the ground or in the engine bay when removing the nut. Is it safe to attempt this with my engine mounted to an engine stand or would it be a better idea to try it on the ground? I plan on using a 54mm socket with an 18" breaker bar and a 5' pipe to use as an extension for the breaker bar. I am currently trying to stay away from impact wrench use as I do not have any prior experience with those tools.

Thanks in advance

 

Just remove the goddamn thing

 

its fine, it doesnt matter if its on the ground or on a stand just take it off

 

The impact gun is like sex.
You don't realize how enjoyable it is until you do it even though it only lasts a few seconds.
You're going to be kicking yourself, because you never did it sooner.

If you don't have access to an air compressor, there's electric versions.
Seriously, even my electric Craftsman 260lb-ft impact gun can take off the flywheel nut.
If it doesn't budge, some help with the torch works all the time.

If you think the big flywheel nut is bad, the 19mm front eccentric shaft bolt is WORSE.
I like to loosen this bolt with the "starter trick" before removing the engine from the vehicle.

That has got to be one of the best quotes I have ever heard on this forum!!! Someone will make this signature worthy!!! +1 RETed!!!

To the OP, as long as you can keep the engine stand from falling over your fine. The breaker bar will work fine, or the impact if your brave enough to try it. As stated before, heat up the nut and it will come off easier.

 

+1 Impact gun. Especially on an engine stand. The whole thing will want to topple over.

Last time I removed the front bolt and rear nut, I was using a 3/4" drive 36" breaker bar, with the engine on the ground. I had to hit the end of the breaker bar with a hammer for some added fun. Trust me, it's worth borrowing an air compressor and impact gun.

 

lol i love the quote. on another note, i have this 12a i am disassembling and i cant get the bastard off. the front nut came off fine with my air impact, no problems. however, after 20 min with a propane torch still nothing, so i get out my electric impact (345 ft-lbs) still nothing. I honestly have never had so much resistance from any nut basically, good luck. i hope you get the bastard.

 

then you have never tried to remove the crank pulley bolt from a 91 prelude.. They are on at around 700 ft lbs.. Well, at least they get that tight from years of driving them..

Just make sure the stand doesnt fall, but an impact will work good.. And dont use butane to heat up the nut.. Use MAP gas.. It burns hotter... That combined with the impact should take care of it... I have never personally taken one of these particular bolts off of these cars, but a stuck nut is a stuck nut..

 

Remove the oil pan and pickup, then take it off the stand and lay it on the floor flat. Now use your big breaker bar. If it's on the stand the big bar won't work as the stand will just tip.

Or, use an impact gun.

 

Thanks for all the input. You guys were right, the only unsafe thing about using the engine stand was that it definitely wanted to tip over. However, I got one of my friends to weigh it down and I was able to get both the flywheel nut and the front eccentric shaft bolt off with relative ease. I was delighted, and now my rebuild can continue :]
