flywheel removal
 

i was wondering if anybody has a special way of keeping their engine from turning over when removing the flywheel. I know the easiest way is with the special tool but i dont have one so ne suggestions?

btw im doing it on my garage floor
thanks

u might want to try heating up the nut with a propane torch first...might help loosen the nut or burn off the locktite

no. what i did was pick the engine up on a dolly, and used some rope to tie it down. then i used a come along to tighten the tension on the ropes, then i used the amazon toyota hub nut socket to yank it off. although it said not for use with impact guns, i slaped it on my 600 ft lb monster, and it zinged right off. to remove the flywheel, just bash it with a bfh, not on anything like the teeth or the studs or the clutch surface, anywhere else is fine, and it flung right off. also, to keep it from spinning, i hacked off a handle from an axe, and i shoved it inbetween the engine and the flywheel, and spun it untill it locked. nedless to say, the handle didnt survive.



now the front bolt, that 19mm bold i believe was a bitch. i used a 20 foot cheater bar, and jumped on that thing after heating it 20+ times and spraying pb blaster all over it. again on the dolly with the same setuip, it took 20 tries with the 10 foot cheater ple and .5 inch socket set to undo that fucker. sadly the dolly didnt survive, nore the front hub cus i bashed it with a bfh out of frustration.

You can get a 3' or 4' piece of flat bar stock at Home Depot for less than $10, and drill a couple of holes in one end that will match up with the mounting holes for the pressure plate. Then, bolt the bar stock to the flywheel, and just let the garage floor stop the bar stop from rotating.

Bar stock comes in handy for lots of other things, so it's not like your spending money for something that only gets used once.

Flywheel NUT?
Impact gun biatch.

The flywheel itself?
Grab a hammer and wail on it till your ears are ringing.

This has been covered many times before.
Do a proper search before asking questions like this.

thanks guys for the suggestions

You can get a flywheel stopper bar and a massive wrench to fit the nut from racing beat or mazdatrix. The bar bolts on using the holes for the PP and keeps it from turning. Itll end up being 50 or 60 bucks, I think, but to me its worth it because it took me 2 minutes to remove the flywheel.
And to actually get the flywheel off, just bang the shit out of it all around the edges with a hard rubber mallet. You can risk doing damage to the flywheel with a metal hammer.

you dont need a specialty tool just an impact, a socket, and a hammer

You don't need an impact.

It's a 2 1/8th socket, which is about 27 dollars at sears, plus a reducer from 3/4 to 1/2 drive which is another 7 dollars.

If you don't use an impact, you MUST use something to stop the flywheel from moving. an impact will just take the nut off without moving the flywheel, and makes the job about 1904957234095823475 times easier, especially if you are laying on your back with the car on jackstands. Not a good place to try and pull one of those mazdatrix/racingbeat flywheel nut tools.

i just hit mine with a impact gun that has 1200 lb of tq

Yeah, the super wrench is better when the engine is out of the car. And you also have to have an impact wrench with at least 400 foot-pounds of power, probably more. And before you say "its only torqued to 350," they get stuck on there and it takes more than that to remove them.

yeah with mine i just touched the trigger and it made 2 quick hits then it was loose

Yes, but not everyone has access to a 1200 ft-lb impact wrench, you lucky bastard.

Ironically, I'm having problems getting the damn driveplate (or whatever it is on an auto car) off. The nut came off fine, but the driveplate is being stubbon. I'll have to try again tomorrow when I don't have to worry about waking up neighbors.

heh. I think my gun is only rated at 230 ft lbs, but I've got it over driven and it came off pretty quick. Of course my engine was out for a rebuild not that long ago. Thats probably why it came off easily.

yeah it belongs to my dad. he uses it to take off lug nuts from his semi :)

3/4 Crafsman breakover, socket.......20lb sledgehammer (twenty bucks) and two hits. Plus six foot long channel iron bolted to the flywheel to stop it from turning.

Heh, I'd like to see you try that shit with the car up on jackstands and the engine still in it. :)
