Clutch Replacement - New Flywheel???


Recommended Posts

Hi,

 

I have a nice new Excedy clutch to fit into my '98 Outback.

 

Question - do I risk having a shop machine the flywheel it and mess it up, do I clean it up with resurfacing air tools, leave it alone or buy a new one????

 

There is what looks like an oil stain on both the flywheel/pressure plate from what I guess was the tranny front seal leaking. It was leaking badly. I tried cleaning the flwheel with brake cleaner and even emry paper with water but the stains are still evident...

 

Don't want to mess up my 380 dollar Excedy or have to pull the tranny again to fix any issues.... want to make this is done right first time!

 

Recommendations appreciated!

I'd just give it the scotch brite treatment. If I had a machine shop around here that I was certain knew how to surface a subaru flywheel,I would probably take it in. But,I've had two of them messed up,and slipped after installation,where as I have never had problems with just reusing the old flywheel.

Depends entirely on the level of wear. For the price of a resurface - $35 and a 15 minute wait for my machine shop to do it - I do them almost every time.

 

A new one is not that expensive either. I would buy a new one only if I suspected the flywheel had been resurfaced more than once before. My rule is no more than two resurfaces - after that they are done. 3 clutch replacements should carry the car close to end-of-life though (for any normal person) so in practice I've never actually had to replace one.

 

Being that EJ flywheels are flat - it takes a mouth-breathing moron to screw up a resurface on one. You pull the alignment pins, grind it, and reinstall the pins. Doesn't get any easier. I'm sure markjw is speaking of experiences with EA stepped flywheels which are routinely screwed up by shops that don't know their business. When I do those I specify the step height to the machinist and I measure it before I leave.

Thanks for the advice all,

 

Looks like I get to choose - I will see if I can get a recommendation for a good machine shop or else just find one local.

 

Daredevil - I am in the process of doing the transmission - have it out - just waiting on the seal from Subaru - the parts guys down here, although knowledgeable, tend to be a little forgetful - Its been two weeks since I ordered the seal and I'm still waiting for it to come in.....

 

May start ordering parts from 1stsubaru from now on - only went with dealer for the "convenience"!

GD has a good point. Only a moron could mess up an EJ flywheel. I did have mine resurfaced the first time I did the clutch. But I got tired of pulling the engine so I went with all new everything the second time.

 

I've found that subarugenuineparts.com is more convenient than the dealer.

 

And cheaper, depending on where you live and what it costs to ship.

 

I've gotten a ton of parts from them and they've been great.

 

I only go to the dealer if I want something now and they have it in stock.

 

SGP is only a day's shipping from me so if a local dealer has to order it and SGP has it, I get it quicker from SGP anyway.

 

How was that trans seal replacement?

 

I need to tear apart my trans and it's got me scared. I'd be more comfortable doing an engine rebuild.

Yup....I forgot the EJ flywheels are flat.:banghead:

 

I've never had a machine shop screw up a flat flywheel. I would certainly have a flat flywheel machined before I put a new clutch pack on it.

Well it seems it comes down to personal choice and the cost of a new/turned wheel.

 

I will hunt around.

 

Daredevil: I have not completed the Tranny re-seal yet - I do have it out of the car though. I was scared about pulling it apart until I read and understood the following write-up:

 

http://www.ultimatesubaru.org/forum/showthread.php?t=90182&highlight=easy+transmission

 

As long as you are not pulling gears off the shafts, simply changing the seals shouldn't be to big a deal.

 

Good luck with yours - I'll keep you posted on how mine goes - once the parts come in!!!

GD,

 

Napa is showing a stepped flywheel for the EJ25:

 

# Flywheel Teeth : 124

# Flywheel To Crankshaft Mounting Holes : 8

Flywheel O.D. : 11.888"

Flywheel Step : +.002"

 

The EJ22 is listed as flat.....

 

# Flywheel Teeth : 124

# Flywheel To Crankshaft Mounting Holes : 6

Flywheel O.D. : 12.384"

 

The one on my car has 8 holes so I assume it is stepped.... kinda looks like it... I will post a piccy if I find out how... (do I need to use a free piccy website to show piccies here?)

That's called glaze. It's not a stain, it's burned metal from riding the clutch too much, or from slipping as the clutch wore out.

Mine had a step. Something like .005, but it was there before, so I kept it.

Glaze it is then! I did notice the clutch slipping when in 5'th gear and going from about 60 to 70 with eagerness.

 

I guess this is the early stages of slip because it didn't do it at low speeds.

 

So the glaze is nothing to do with gear oil getting on the clutch plate???

New pics :)

Nice shiney new flywheel and pilot bearing (a tad better than my old bearing :))

The usual suspect - oil separator cleaned up and ready for new part.

Just waiting on new parts so I can re-assemble...

Nice! I just split the new-used trans I put in my Outback last week. I was surprised at how easy it was.

 

It was much easier to split the trans and replace all the seals than it was to just remove it. Gloyale's write-up on the front seal replacement helped a ton.

 

So, you sprang for a new flywheel? Genuine Subaru?

No, I got it from Napa - cost me 95+tax.

 

I did have my old one re-surfaced but the machinist mentioned that it was a little bit warped. I didn't want to take any chances so I bought a new one.

 

The clutch on my Brat judders sporadically and I don't want a repeat of that on my OBW.

 

Better safe than sorry me thinks!

 

Can't wait for the tranny seal kit to come in so I can get it back together. I haven't even driven it properly since I bought it and its about time now!
