Hey all

Just wanted to say hi to all of you since I'm new. But also I have a question about that huge nut on the flywheel. I just got my jspec and wanna put on lightweight flywheel. My impact wrench won't do it. I tried with breaker bar, but i don't have good flywheel stopper. What I was wondering is if I could heat up the nut. Would that damage a pilot bearing or any seals?

 

Heat will be fine..Thas what I have used.

If all else fails, take it to a diesel mechanic. They have HUGE impact guns that could take off anything.

 

Speed is right, they will have a 3/4 impact fed by a huge compressor that will pop the most stubborn applications.

 

My friend took his engine to a local mom & pops tire shop and they busted out a HUGE impact gun. It seemed that they were looking for any excuse to use it and charged him 3 bux to loosen the nut.

 

If you have a big prybar, you can turn the flywheel such that the prybar rests on the little round nubs sticking off of it. Turn the nut with the wrench until the prybar is resting on the ground with tension applied when you turn the nut. Have someone hold that prybar in place, put your breaker bar on the bolt and jump lightly on the breaker bar until the bolt pops. Did this yesterday with my front pulley bolt.

Im sure I didnt explain well, so I may make a video of it if needed.

if you have a spare pressure plate....bolt it onto the flywheel to form a horizontal 8. then try unscrew that nut... thats what i did after my angle bar was bent to hell.

Only try this if you have a spare like i did. worked like a charm.

 

thanks guys, diesel shop is a good idea.

 

I'm getting ready to remove a flywheel also, what is the size of the socket for that?..hopefully it will fit a 3/8 impact wrench.

 

heat it with a propane torch>> then apply wax on the nut and threads. wax is a machinist's secret....

 

First, a 3/8 impact wrench will NOT take off the flywheel nut. An impact gun with a rating of less than 400 ft lbs will not take it off.

Its a 2 1/8" socket. Its freaking huge.

 

yeah its 54mm or 2 1/8". Sockets this size usually require 3/4" drive, but u can buy and adapter in sears that will reduce it to 1/2".

 

Anybody else broken a few 3/4" breaker bars before giving up and getting a good impact gun?

 

I have a good snap on impact gun, but it won't do, you can get a huge impact gun like the kind they have in machine shops but you also gotta get a huge compressor. Mine's a Big POS
