new cluch for EA81 with d/r 5 spd

[joedivola]

Forgive a newbie for needing a little hand holding, tried searching but still unsure...

 

I recently bought an '85 Brat already converted to 5 spd d/r, but with a very soft clutch. Based on what I've read here I'll need the kit for the EA82, but it looks like there's two sizes (7-7/8" and 8-7/8"). I have no idea where the transmission came from, so is there a way to determine which is the correct kit? Is there anything else I need to know before I go in?

 

Thanks in advance,

Joe

I believe with the EA 82 4wd you want the 8 7/8 diameter unit (24 spline) if I'm not mistaken the 7 7/8 is 21 spline and used on the front wheel drive transaxles.

[Mr. Brat]

Yeah the smaller spline is the front wheel drive. I just put a XT6 clutch in my 85 brat w/ d/r 5 spd.

order for a 1990 loyale 4wd 5spd, you cant go wrong. the smaller disc is for fwd's

[GeneralDisorder]

It depends on how the conversion was done. It can be done two ways - with a 4 speed flwheel/PP and 5 speed disc, or with all 5 speed components and the timing marks transfered over to the 5 speed flywheel and a bit of material ground off the engine's bell-housing.

 

It will be a 225mm clutch setup as the 200mm for the FWD's and very old 4WD's will not fit the input shaft on the 5 speed 4WD tranny.

 

You will have to tell us which flywheel it has for us to answer correctly as to what you need. A picture of the timing marks and the flywheel would likely help.

If that's the case, I'm wondering if I can tell by examining the bell housing to look for the "modification" prior to separating the engine. Or... any idea how many teeth there are on the EA81 flywheel? If I mark one tooth and count while I turn it one revolution would that work? The concern here is that I'm borrowing a hoist from a friend, and I'd hate to have it tied up any longer than necessary. It never seems to work out as planned, but I want to at least attempt to have all my ducks in a row ahead of time!

 

Again, thanks a bunch for any and all input!

You won't be able to see the modification to the bell-housing with the engine still mated to the tranny.

 

If you can take a bright, clear picture of the flywheel from the timing mark hole I can tell which flywheel you have.

 

Another way is to look for TDC on the #1 cylinder and see if it corresponds to the timing marks - and if it does - is there another set on the flywheel about 30* away from the correct set? That will indicate a 5 speed flywheel that has been retro-fitted.

Tough one to get a good shot of, hopefully this'll do

 

[GeneralDisorder]

That is the 4 speed flywheel. So now you have a problem - did they use the 4 speed pressure plate or the 5 speed...... *most* of the 5 speed clutch discs will not fit the inside diameter of the 4 speed pressure plate. The trick is to buy one for an '85 or '86 - those are the one's that fit.

 

Until you open it up - unfortunately there's no way to tell. The only thing you know for sure is that they used the 5 speed disc, T/O bearing, and pilot bearing. You won't know which pressure plate till you open it up.

Could you tell by pulling the starter out? The outer edge of the two 4 speed flywheels where the pressure plate bolts up should look different.
