I'm in the process of replacing my clutch and right now we have the tranny out and the old clutch out. I'm waiting for the new clutch to come in from RX-7 Store. I was wanting to resurface the flywheel but I didn't know that it is held on by one big nut that hold it on the E-shaft. Since a special tool is required and a specific preload has to be put on the nut I really don't want to mess with it. Is it necessary? My flywheel is smooth all the way across. When you change clutch's is it necessary to resurface the flywheel. I have a remanufactured engine, would a new flywheel have been included with the remanufactured engine.

 

If it is in really good condition, you can leave it and be pretty confident that it will go fine. Mine had massive scorches and heat cracks so I payed the 35 bucks to do it. I didn't buy any special tools. Just 4 foot long thick angle iron, a breaker bar, and an impact. Get creative, I would recconmend you still get it machined for safe-keeping.

35 is a pretty good price for a stepped flywheel with pins

if you do have it resurfaced you might look into shims.

Depends on how picky you are but they do make shims for our cars.

I posted something a while back but doesn't seem like anyone uses shims on resurfaced flywheels.

Then again i really never heard about it till after i put my flywheel in

 

the problem isn't getting the nut off, it is putting it back on that I'm having concerns about. Do you just tighten it down? Does there need to be any specific preload on it, like on the main pulley on the front of the engine.

 

YES! it is recommended that you resurface your flywheel...

 

just make sure the key is in correctly and impact it down with some thread locker

or just use the most force humanly possible.

use a 19mm on the front or a flywheel lock to do it.

I fabed a metal bar with one hole in it. I screwed the bolt in and let it rotate until it hit a dowel pin. Then used that to stop the flywheel.

 

This is bottlejockey's roomate, i helped him with the clutch tonight. We saw pics of some other flywheels and decided to just try emory paper as ours appeared much better. FOllow this link to see pics of his flywheel we think it looks good, WHat do you all think?

Ha! I got my flywheel machined for $23 by a company that has been doing specialized and racing clutches and flywheels for 35 years. They put it exactly flat too (was off by 0.030") and put the proper step in it... its gorgeous... looks brand new now. If you're in the Atlanta area Specialty Clutch is the ONLY place to take a flywheel... they also sell clutches at excellent prices... a kevlar/ceramic 6-puck is under $300 including pressure plate the guy said. He used to own several RX-7's. And my flywheel looked better than bottlejocky's before I took it in... but I think it still needed it.

 

my clutch came with specific instructions for resurfacing. if they aren't followed, the warranty is void. has a specific amount of step-in listed.

 

Digital:
Where's this place in Atlanta? Do they have a website?

 

Yes, if it looks like that those little marks on it are not good, mine looked only a little worse than that but after I put in my new clutch it got very bad. I would always get it resurfaced if it has any sort of marks on it.

 

OK kids I do this for real a good 1/2 impact takes that nut rite off , a larg hard rubber hammer hitting the outtrer rim of the fly wheel gets the fly off, putting it back on DON'T go and get one of thoese super snap on air tool to much power Harber Fright will do low air 120 psi run the nut down till it stops should be some where arund 250 ft/lb. I know some one out there is a none belever just go to your Mazda dealer and ask how it's done

 

Never seen a website for them but they are in the phone book under Specialty Clutch and they are out I-20 West near downtown (Lee Street area).

I walked in, set an aftermarket japanese flywheel with no information on it down on the counter and the guy said "oh, that's for a second gen rx-7, isn't it?" I knew I was at the right place.
