Need 2003 4.0 SOHC Flywheel Help ASAP!

Well the Spec Stage 2 clutch is going in when the engine arrives. Last time I replaced a clutch(79 f150) I neglected the flywheel. I'm under the impression that it needs to be resurfaced or something. I'm trying to find a replacement flywheel but every well-known brand has no part listing for a 4.0sohc. Would I be better off having the existing one resurfaced or is there something out there that I'm just not finding??

never in my life have i heard of doing anything to the flywheel when replacing the clutch.......unless your is cracked, warped, or you just feel it should be done, you shouldn't have to replace it.....

you dont have that many miles do you? i mean i would just resurface it.

i dont know that much about the clutch or the flywheel so im prolly not the best to give advice.

but how could you make a better flywheel? maybe make it out of better material?

i dont see why resurfacing it would be that bad.

I don't know much about it either, that's why I posted. lol

Truck has 56k. Donor engine has 6k.

Also, I just found out the engine is from an '02. Is there a TSB/recall about the timing chain issue if I run into that problem? I'd almost rather have them address it before I get it.....especially if it's free =]

I wanna get in this hog, drive it home, change the rims/tires, and run the **** out of it.

Resurface it. When I replaced my clutch I just had the flywheel resurfaced, and it works great. Trust me, save the money on buying a new one, you don't need it.....

i would not worry about the timing chain. there is a recall on 02 back but they didnt really fix it just toned the rattle down.

timing chain is gonna rattle around some. the only ones i have ever heard of breaking are when its on a supercharged engine

if you can get it replace for free i guess you could, the way i see it the more you mess with the engine the more it makes noise because it will never be put together like it was originally

because there isn't a big following in the aftermarket world for performance parts for a 4.0........

might give this place a call if you really want an aftermarket/lighter one...

I thought you couldn't put an engine in a vehicle when it is older than the vehicle. IE no '02 in an '03.

At least from a legal stand point.

you are not susposed to......but the law varies state to state.......depending on emmissions laws in that state...

They might not even notice since it is the correct engine and the emisions hardware is all there. Besides, I don't think Ford changed anything from those years anyway, but I know 04 is diff.

Its nice here in Michigan, we don't have testing.....

Bastard. I think here in California we have the strictest emissions laws in the states. Well at leat we dont have to change to a completely new engine like in Japan.

When i had my clutch done, the only flywheel that is available is the stock ford part. So if you can resurface yours then do it.

Whenever I do a clutch at my shop I like to resurface the flywheel. Saves money, and time, it really doesnt take too long for a good shop to do it properly.
