Owned by a flywheel nut
 
OK, tried most of the day to get the flywheel nut off of my FD. Looks like it's been off at one time, but it wouldn't budge. I literally broke a fair quality 18" breaker bar with a 24" cheater pipe as an extension.
Now I understand that these things are put on with something like 350+ ft/lbs of torque, but mine must have been put on by some Summo wrestler or Binky the 800 lb Gorilla. I bought the rear seal etc to install w/my clutch but I getting ready to give up and leave the flywheel. Anyone got any suggestsion or know where Binky lives now?

Heat it up!

Air tools....

94RXMAGEE 02-03-04 08:21 PM

I agree with the air wrench, mine came off with no problem.

Sgtblue 02-03-04 08:28 PM

Impact was tried, didn't even come close. ISUposs and I also tried heating it up with a propane torch. Might be able to give that another try though, the flywheel was really conducting the heat away from the nut fast and I don't think I got it real hot. I was just afraid of cooking the bearing or worse.

I'm tellin ya, this bad boy is on there. I used the above breaker bar and cheater pipe extension. While grabbing on to the left front a-arm, I pushed with both of my legs. Had to have put well over 450 lbs on it before breaking the breaker-bar. I was even getting afraid I might do some damage to my motor mounts I was pushing so hard. Unbelievable.

Impact took mine off in about 8 or 9 seconds. Ingersoll Rand 1000ft-lb reversing power...oh baby.

LOL, just take a look at what i used :D

Wow... you broke the breaker bar?

poss 02-04-04 01:22 AM

Jim, we should break out the cutting torch for tomorrow. :D

powermalex 02-04-04 12:04 PM

Use a dremmel instead and break the nut.

mad_7tist 02-04-04 12:19 PM

you just need biger air tools! and yes it is a bastard. i have that IR 1/2 inch gun and it just wings that baby off

Enconsiderate 02-04-04 12:20 PM

Just remember righty tighty, lefty lucy. LOL
Wouldn't that be funny if your were turning the wrong way.

Kento 02-04-04 12:39 PM

Some sort of impact-type tool is necessary for this. The problem with using leverage like an extension on a breaker bar is that the torque is applied gradually (compared to an impact), and that's often not enough to break the torque and/or contaminants in the threads that are holding the nut on. Although not in this case, it can also inadvertently cause damage to other parts if the impact's quick torque application isn't used.

DrunkenBowler 02-04-04 01:04 PM

Wrong way wat. Anyways, instead of a 24 in extension, get a 4 foot extension, and a new breaker bar. :D
Or u can go easy and take the easy way out and get big tools.

Ingersoll Rand make very powerful airguns, but the one i undone yesterday took a 5ft cheater over a 24" proto breaker bar, flex was like a bow before it let go,those proto breaker bars are the best.3/4" bluepoint impact wrench wasn't doing shit.
All depends on how much locking paste is on there,some break easier than others.

Kento 02-04-04 04:17 PM

The "impact" doesn't have to be pneumatic.

vspecpgt 02-04-04 05:01 PM

holy cow.... mine is sitting waiting for me in my garage.... now i'm getting scared.......

BLKTOPTRVL 02-04-04 05:46 PM

I used a one inch socket and a 7 foot cheeter to remove the nut from my '71 (also 350 ft lbs.).

From my current experience, I agree with KENTO for exactly the reasons he stated. #1, the quick application of torque to break it loose and #2, if I would have kept going, I think I would have begun stressing the motor mounts unnecessarily. I could really feel and see the engine rocking back and forth when I was pushing and it didn't look good.
The reason to pull the transmission in the first place was to fix my 5th gear synchro and replace the clutch. I've got about 60K on my car and the flywheel surface really didn't look too bad so I re-packed the pilot bearing w/grease and left it. That friggin' flywheel nut beat me....this time. But if I ever have to pull the tranny again I'll be better prepared. Thanks to ISUposs who helped out ALOT, I now have some experience. And next time I'll have a better compressor and a much bigger impact. ;)

impact wrench bud 2 seconds

I had a 4ft bar and it wouldnt come off with my dad and me pushing on it, so i cut 1/3 of it off and it came of no prob! ;)

It's not easy when you don't have $1500 and space for big tools.

Yep Yep.
What you might need is get a good breakerbar and a small sledge hammer.

Have someone hold the socket in place with the nut and whack the breaker bar with the sledgehammer.

Godzilla-T78 07-04-04 11:30 PM

haha my stinking $1000 air tools couldnt do it, I just sprayed it with oil, drank alot of coffee, got really pissed and my big german ass took care of the rest... I hung under my car on it for about 2 minutes and the constant pressure of 300lbs pulled it loose.
