i STILL have vibration. harmonic balancer? PLEASE help me

#41
went back to the machine shop on my lunch hour where i got the fw resurfaced. yea, i wasted my lunch hour. i brought the fw in and was nothing but nice. didnt even make any accusations i just pointed out the wear pattern and that only 25 easy miles were on it. there was even a cluster of hot spots grouped together in once place in 25 miles. to me, my original 110k fw looked better than this 25 miles resurfaced one. i told him after i replaced it with a new one from frpp that it helped greatly with the vibs. i all but wrote out a big flashing sign "can i have my money back". no help at all, not even too look at it was offered. he said there was not really a way to mess up the resurfacing. the 110k fw that came off didnt have the swirl marks. it did have a few hot spots but where more evenly spread around not as noticeable.

precision auto machine's customer service in mcminnville, tn sucks balls :notnice:

any one doing a clutch swap and fw, i strongly suggest just buying a new one

Of coarse hes not gonna admit he did a crap job.

This is exactly what I went thru.Step by step but over a longer period of time.I wish there was someone like me.To tell me,so I didnt waste so much time. At...The time...:)

So....are you gonna be cheap and get a wimpy clutch kit?
Or try to just replace the disc?
I guarantee 99% u get a new clutch kit and problem will vanish.

Just do the math on it like I said above and its obviously the clutch and pressureplate.Its a 4hr job and 300bux but youll be happy as hell once its done.

I was lol when i read u went to the shop.
It sux man..I know.They dont gaf
But
Listen...especially to this
You have hot spots also? Your pressure plate and disc are definitly warped.
The flywheel is much stronger than the disc..And it got hot enough to heat the flywheel and warp...most definitly that same heat warped the clutch and the pressure plate.
So when you gonna swap the clutch? I wanna hear your happy posts after your done.
I had a clutch once,that made me think the trans was shot.
I pulled it and brought it to 3 shops.
Finally I looked at the press plate and a strap was cracked

That strap made the tranny slip out of gear in 1st ,grind 1st and 2nd lthat sounded like gears had teeth missin and sometimes it worked flawless.
I had a website that showd about 100 pics of different clutch problems and what causes it and everything.Im pissed I cant find it.
IM gonna search som e more. I thought it was lucus or lucas trany or clutch but im not seeing it.
They even have a 30 question quiz test
anyone know the site?

if its the clutch, why is it giving me problems as soon as i changed flywheels and transmissions? not calling you a liar im just curious. its a centerforce with 10-12k miles on it....and i drive like a grandpa. like i said, my 110k mile flywheel had hot spots but not grouped together and not as near as noticeable. and thats the flywheel that was used with the centerforce. this resurfaced wheel with the same clutch had 25 miles on it and it looked bad. may be the clutch but i just dont see how if it gave me no trouble at all until the fw was changed.

you laughed when i went back to the shop but i went back thinking they would back up their "reputation".

but to answer your question when i am replacing the "wimpy" centerforce clutch, im not. whether that is the problem or not i just dont have any money to put into right now after all this.....not $300 plus

take a peek...u got a burnt fly and pressure plate and an uneven worn clutch.=bad vibes
http://images.search.yahoo.com/sear...eg&no=13&tt=918&oid=fa34724db3188ee8&ei=UTF-8




prly cause you put the bad flywheel on and it beat up your disc and pressure plate.you could have bolted something on wrong if the vibes came only when u did the swap.
but,Im tellin ya,its the pressure plate.If u had hotspots on the flywheel,the rest of the clutch setup was toasted as well.
U gotta see how many things can be wrong with a pressure plate and clutch disc.
Im talking about 20-30 different things you wouldnt notice by eye if your not a clutch specialist.IM still trying to find that dam link.
I found the luk clutch site,I thought that was it

but my flywheel did not look like that. either of them. but even if it was the flywheel, i jsut dont understand how it could do that much damage to the pp / clutch disk in 25 miles.

it was assembled right. another mechanic disassembled everything and reassembled to swap flywheels. he said everything was put together correctly.

Well...think of it like this

u changed the flywheel ,it helped,the balancer also helped..only thing left is the pres plate and clutch disc :)


U get a vibe around 3500-4500 rpms and u can drive right thru it right?
if u gun it,its barely noticable at all?
u get it in nutral...
u get it in gear
clutch in
clutch out
coasting and reving
neutral coasting and reving
coasting in gear clutch in and rev
it dont matter

and to be a lil more accurate its the pres plate.
if it were the clutch disc u would feel changes or hear changes
in the peddle also.

Oh.,.....one more thing....the plate has a specific spot where its balanced to the flywheel . Most people dont know it but if u reclock the presure plate to a different spot..it helps
also be super sure the dowel pins are set all the way down!!!!!!!!!!!!before u start torquing the thing....and use a criss cross pattern and 3 sets of turns like 15lbs 25 thern 50ftlbs example

Not to burst any bubbles here. I am having the same problem as you are right after i read this thread. my car just vibes out of the blue.

And guess what? i changed harmonic balancer, engine mounts and trans mount, even reinstalled the pulleys, checked the driveshaft and u joint, still having problems..... it is not the clutch,,,if you did not have the problem before with same clutch it is not that.

My friend at ford says IT IS THE FLYWHEEL or NEEDS DRIVESHAFT balancing or bearing retainer might have gone bad. check those. make your life easier,

I am doing all of them for peace of mind.

vibrates while sitting still and revving or going down the road or both?

by the way my flywheel are new also but it would have been a good idea if you and i have changed the whole clutch lit while doing the flywheel. short cuts cost you more money in the end. but at the same time you are doing your clutch, have your tech balance your driveshaft also and change the retainer bearing as well. after that you should not have anymore vibration.

Good luck man :)

both, around 1500 rpm rev at netural, in gear around 20 mph, then goes away,
my friend is tech at galpin ford here in cali and he seen alots of these problems.
he said 50 % needs driveshaft balancing, others are flywheels and bearing retainer problems. they are cheap problems. i am fixing it
 
#51
my harmonic balancer and engine mounts and trans mounts were shot too. i changed it to poly ones from Energy, they are fine no complains like other people here says. my shifter was even vibrating when this started. aroung 4k rpm on freeway by the way. it was crazy....i thought my trans was done. but my friend told me it was common problem to our year 5.0
 
#52
you got a head start then i do my next project will be flywheel and at the sametime clutch kit, driveshaft balancing, changing the retainer bearing,

but only thing you have to do is balancing and retainer now then your problem will END! just get a new clutch man do it again, and sell the old center force on ebay get some money back :) and just to let you know ford racing clutchs are made by center force...how about that...
 
#56
I have never had this problem with my honda and it had whooping 90 horse power to the flywheel and it would hall ass down the 1/4 mile at 18.5 seconds, with my stereo on, i never had driveshaft problem at all or clutch problem, it handled all the horsepower i was making, i was going to put cage in it for the safty measure but i sold it due to theft. i had big plan for that car...adding robot sticker and adding shark tails...etc...etc..what a shame....


I am kidding don't shoot me :) LMAO

dont see balancing the ds will help as it vibs while sitting still and driving and never vibed at all b4 trans swap. retainer was replaced 10k-12k ago. pilot bearing 50 miles ago. dont really see it being my clutch either. no probs b4 and only has 10k-12k as well. even if it was tho, couldnt pawn it off on someone else on ebay tho
 
#59
ok let's rule all that out of the way.

?But i dont see anywhere in the thread that you have balanced the flywheel after you resurfaced it. DID YOU? you have to balanced the flywheel otherwise that will cause the vibration too.

anyways i am taking steps here too so i will come to end of this project within few days. i will find the problem,
