we can't get the main nut in the center of the engine cover to break free. anybody have any tips?

 

What are you currently using?

People have had luck with the following:

* Impact gun. Using tigtening first to help break the locktite loose, then going reverse
* Large breaker bar
* Using a blow torch to heat it up

 

Ahh damnit! I thought I had clicked on "Lounge", and saw this thread title... I lol'd!

 

impact so far. just talked to my guy doing the work. he said he just got a socket with i diff taper to see if it might allow his impact to hit it harder.

 

i hope this works. we thought of heating it but were afraid it may damage componets internally.

 

I've personally never needed to heat one up to get it off, but I've heard it done quite often. I larger breaker bar is typically what I end up using. My current impact only has about 450 ft/lbs of torque and it rarely does much damage to that bolt.

 

I loaded the shortblock up in my SUV and drove it to a tire shop that does big truck tires.

The guy hit it with a 1" impact and it was off in about a second.

 

i welded a pipe to an old front pulley for my FC... you could put a 5 foot cheater bar on it if need be

 

This guy above made a tool like I did long ago ( and advertised here ). After you bolt the "holding" tool on you then take a 3/4" breaker bar with cheater and that E-bolt eases right out. I would NEVER apply heat to that bolt, although a lot of folks here do.

My wife held the holding tool while I broke the bolts loose. Done 4 of them this way and never a problem
