A couple of weekends ago, I completed my first engine pull. Didn't go too bad, had to use a pair of vice grips to get some bolts off, but other than that, it went pretty smoothly. I want to rebuild the engine and do a little porting so I went to take of the flywheel. I only had sockets that went up to 2in so I had to wait until the next morning to get a 2 1/8in socket. I tried everything to keep the flywheel from turning when I turned the nut but nothing worked.

I am just wondering if you guys have any tricks for removing that flywheel nut. I don't feel like shelling out the money for a flywheel holder from Mazda or whoever sells them. Any tips would be appreciated. Thanks.

 

Chisel and hammer. be sure to grind the sharp end as it will slice the nut.

 

I want to be able to reuse the nut.

 

you can stil re-use it.

 

Try this.

My flywheel nut was all jacked up from the PO using a chisel (I guess he didnt dull the point tho cause it was messed up). I was able to grind the deformations down and got the 2 1/8 socket on. A little PB blaster and a few seconds with a impact wrench and it spun right off. The pully nut on the other side of the eccentric shaft is what gave me trouble!

 

1/2" impact ftw.

 

I use a 3/4" air impact wrench to drive the socket.

 

GREAT idea!!! That is exactly what I was looking for.
