Is there any way possible to remove a 54mm flywheel nut without getting the specialized tool or going to sears to get a 54mm socket(yes they have one my friends found it) The only reason I ask is because I dont feel like buying something im only going to need once. If theres no other way I guess ill just buy one. Anyone know what the nut is torqued to?

 

your going to need it more than once, i would just buy it it will make life a lot easier. the torque spec is something like 300ftlbs.
the other way to get it off its to use a chisel, and a big hammer.

Buy the tool. Always buy the tool. Something that big isn't something that'll just come off with a monkey wrench, and if you try and ruin the nut then your day is done.
I don't know the torque off the top of my head, but if I remember right it's big.

If money's an issue, buy it then sell it. I need one!

 

Definately going to need the socket. torque is over 500psf from the factory. I have only broken one out of six loose by hand. Good luck.

peace


forgot to add I had a 6ft breaker bar on the one that came loose

 

God almighty, 300ft/lb's I thought thats what I remembered it being I kinda figured I was going to need the tool. Whether I break it or not isnt a big issue since im not going to be using this engine. I just want the rotors and housings for display I think rotary preformance rents the tool out, I think I'll go give them a call.

 

thar she blows

 

rule of thumb, if you need it one time, then you will need it again some other time, jus go buy it it'll be worth it in the long run

 

yeah i was just thinking, im going to need it when i put on my lightened flywheel on my 90 GTU.

 

i just pulled mine off. i went to sears to buy a 2 1/8 inch socket and used a impact wrench and it came right off. i didn't have to buy the flywheel holder tool either. i highly advise investing in an impact wrench. i bought one from harbor freight tool for $20. so their not to expensive and you can use if for every thing else on the engine

 

You could get a cutting torch and cut through it, or maybe a hack saw blade that might take a few years...

LOL

Just get the proper tool, I bought mine for a one time thing, and ive used it maybe 10 times

 

Whats this magical tool look like? Is it just a big wrench or what?

 

Not a very good picture but here's the tool:



This is helpful too:

 

thats it? just something to hold the flywheel and a big wrench to loosen teh nut? hmm, I was expecting something a little more high tech. How much does it cost?

 

Mazdatrix wants 36 for the wrench and 23 for the holder thingy. But they want $142 for the dowel pin puller! Ouch! What alternatives are there for that tool?

 

Dowell puller? A bolt and a dent puller for about 10 bucks

Thats what I always used

As for the flywheel question just buy a impact wrench and the proper socket. Its not like they are expensive...

Proper tools , theres no subsitute

 

The 2-1/8 socket from Sears with a good impact works fine for removal. But torqueing it down is another matter.

Also, on mine I needed a big enough puller to get the flywheel off. I ended up buying one at NAPA for $20 or so.

Assuming you have a torque wrench that goes high enough, or can calculate the right torque with a standard torque wrench and extension, you will need somthing to prevent rotation while tightening.

Rather than spend the bucks on the holder "thingy" (which admittedly is nice), get a solid piece of steel bar stock about 2 foot or so long, drill a couple holes in it that mate up with the pressure plate holes in the flywheel, and bolt it on. It will prevent it from moving as you torque it down.

I haven't found a cheap substitute to pull out the pinion bearing and seal from inside the eccentric shaft. I ended up borrowing a tool from a mechanic friend.

Actually, now that I think about it, I did hear of a cheap way to remove the pilot bearing and seal, though I have never tried it!

Find a bolt or steel rod with a diameter as close as possible to the inside diameter of the pilot bearing. Fill the inside of the eccentric shaft with a heavy grease. Insert the bolt or rod, and hit it HARD with a hammer. The force will compress the grease, pushing the pilot bearing and seal out.

Like I said, I've never tried it, but worth a try.

 

Puller BLAH I broke 2 of them on my 12A once, pullers suck. all you need is a framing hammer, or a small box hammer.

Turn the flywheel 1/8 turn, hit it from the back side, turn 1/8 turn, hit it again, turn it , keep repeating till it comes off... Remember to leave the flywheel nut threaded a few turns so you dont break your foot, or loose some teeth on the flywheel from it bangin' the floor.

I got a 3/4 inch drive snap on impact gun, I have seen it countersink lug nuts set on power 3 setting. It goes to 5... Thats like 450 lb

 

Cheap puller suck.
If you need a good puller get an OTC.
You will not break it.
They have a lifetime guaranty if you do.
The only exception is using an air tool on the screw.

Hammer has worked for me on over 10 motors

I would have like to had a nice puller for the Cosmo POS , it had a flexplayte and I wanted to remove the counterweight and I had a hell of time with it

 

I made a puller out of a big piece of metal. drilled some holes an used a really long bolt to turn in to the ecc shaft. it worked great

 

Ok, how do I upload pics to this thread? I have pics of how I have done it b4.

 

racing beat sells a puller for much cheaper i think i got mine for around 20

p.s.- i mean tublular dowel puller

 

Its called a BOLT! Thread a lug bolt into the dowel pin and pull it out with the rear hatch holder/ I mean vise grips! Man you guys need to do pushups or something.

 

Ok so i got the huge friggin bolt off, ah the wonders of a dremel and a chisel But now im lost as to what to do. Any help?

 

Well tell me how to post pics and Ill reply with pics of my contraption!
