Title: Stealthy Flywheel Weight Removal
Post by: Gage on April 28, 2013, 04:55:20 AM
I think I have a stealthy flywheel weight on my flywheel. Do you need a special tool or something to remove the center bolt? I see 4 bolts around the flywheel but I'm thinking those are for balance right? :?

Depending on the year, make, and model, there is four set screws around the outside of the fly wheel.
Those must be backed off before you try to remove it.
If you don't have the Removal tool such as  shown below:

There is a couple of different ways you can remove it depending on how tight it is.
Sometimes you can put two bolts in the front of it and then use a lever to loosen it up.
Other times when they are really stuck I have used a set of Vice Grip Locking Chain pliers such as shown below:

Probably some other good ideas as well..

I've never seen them reverse but they can be really hard to remove especially if they were put on with loctite  :-(

I am trying to take off the flywheel-Stator on my 1997, and that Nut is not budging. PUTTING lots of torque on it any suggestions?

Have you loosened the little Allen head set screws on the outer diameter?  It is not LH thread, it threads on in replacement of the nut.  Do you have the spanner?  Mine was a pain to get off too.  I think I ended up holding the flywheel with a strap wrench.   Make sure the blots for the spanner are not too long too.

Impact wrench and heat.

i made a little tool with 2 studs that fit into the face holes on the flywheel to hold it. a strap wrench tried to fly out of my hand and smack me in the face, and the clutch/flywheel tool i had, while nice, didnt fit the shallow grooves on the outside of the flywheel well and looked like they would slip right out.
+ an impact wrench on low setting and spun right off.

edit: sorry just noticed you have the Stealthy version. dont know if it has the front holes you could grab onto like the stock flywheel.

Thanks for the input Gents, i ordered a lockup tool, and an impact wrench and will report back in with resolution.

with the lockup tool you will not need the impact gun.  Make sure the 2 bolts on the spanner are not too long and use washers or spacers between the removal tool and the weight to keep from bending the bolts.

Lockup tool worked like a champ, nut comes right off. Flywheel took some torque, and POPPED when it first moved on the shaft.

Thanks for the intel on this, and I recommend the lockup tool!!
