TIMBERTIGER Posted August 22, 2014 Share Posted August 22, 2014 Ok, so I am replacing the clutch on my 1986 BRAT GL and I have run into a load of problems. First, I assumed the engine and tranny were factory 86 since the car had 1 previous owner and only has 113k but found that this was not the case when I tried to install the 86 clutch kit. After playing musical clutch parts I have learned that you can have 3 completely different throw out bearings and clutch discs from 82-86 and I have finally narrowed mine down to 83/84. I finally have the correct disc and throw out bearing after ordering the kit for an 83 but the pressure plate does not fit. Were there any differences in flywheels as well? The pressure plate that came with the kit has these "ears" that will not fit in my flywheel so I can't even bolt it on. I am suspecting that the kit came with the wrong pressure plate but would like some advice before I run back to autozone AGAIN and end up looking like an idiot. I have attached pictures that should help illustrate my discrepancy. The first picture is the old pressure plate, the second picture is the new pressure plate, and the third picture is both pressure plates stacked face to face for comparison. Thanks for any help!

Crazyeights Posted August 22, 2014 Share Posted August 22, 2014 There are 2 size pressure plates (diameter) that I know of (FWD) 7 7/8" and (4WD) 8 7/8" if I remember correctly. Same goes for disc and 21 and 24 spline respectively IIRC. Link to comment Share on other sites More sharing options...
swootton Posted August 22, 2014 Share Posted August 22, 2014 All 1978-1987 Brats take the same 200MM disc, pressure plate and throw out bearing. All listings on Daiken(Exidy), Parnut and OE cataloging show 1 part number for each. The Brat uses a 200mm clutch which would normally "only" be in a 2wd car. The 4wd cars use larger diameter clutches. Some one may be looking up a 4wd application, but the Brat does not use a "4wd" clutch. The larger clutch will not fit inside the smaller bell housing used in the Brat. Link to comment Share on other sites More sharing options...
skishop69 Posted August 22, 2014 Share Posted August 22, 2014 Something you will learn about the Brats is the catalog is not always right. You need to order a clutch pack for an 84 Brat. There was a flywheel change in 84 though I don't know if the pressure plate size changed but the disc didn't. I do know that all the Gen2 Brat clutches I've done, I've always ordered for 84 and never had an issue. Link to comment Share on other sites More sharing options...
TIMBERTIGER Posted August 22, 2014 Author Share Posted August 22, 2014 The kit I ordered was for an 84 BRAT. Everything is correct including the surface diameter of the pressure plate but the little "ears" on it are all that is keeping me from moving forward. I just ordered a kit from Oreilly's and it should be here tomorrow. We'll see if the pressure plat in that kit looks any different. Link to comment Share on other sites More sharing options...
TIMBERTIGER Posted August 22, 2014 Author Share Posted August 22, 2014 Here is the 3rd picture. You can see the face of the pressure plates is the same but the new one has these stupid little "ears". Link to comment Share on other sites More sharing options...

The larger clutch will not fit inside the smaller bell housing used in the Brat. This is BS. Starting in late 83 the brat got the larger 225mm clutch disc. Still with 21 splines (7/8ths") The bellhousings are all the same.....the 2 types can be swapped back and forth........just must use the matching size flywheel and PP and disc. TimberTiger...that PP is wrong, shouldn't have those ears. 1 Link to comment Share on other sites More sharing options...
epix Posted August 22, 2014 Share Posted August 22, 2014 Brat uses the 225mm disc. 225mm (8 7/8") disc 21 spline, 22mm shaft Here are some part #'s of what would work on the Brat.

skishop69 Posted August 23, 2014 Share Posted August 23, 2014 +1 Gloyale. It isn't right. EA82 maybe? I'd have to go down and look at one of my spares. All my clutches have either been NAPA brand or LUK and I've never had a wrong one. 1 Link to comment Share on other sites More sharing options...
jono Posted August 23, 2014 Share Posted August 23, 2014 should be plenty of posts in here you could search from last 12 months on enough info. I have had both 200mm and 225mm clutches in my GEN2 Brumbies/BRATs. My made in 84 possibly for 85MY was a 200mm but had engine change so no idea if it was originally 225mm Agree with skishop entirely with listing accuracy - even got some EA82 timing belts - printed on the box to suit Brumby The EA81 4WD clutch forks were light bluey greeny colour too until somone decided to paint them black to match rocker covers change to black . Not sure if the colour change of the forks signified change from 200mm to 225mm ? Link to comment Share on other sites More sharing options...
TIMBERTIGER Posted August 24, 2014 Author Share Posted August 24, 2014 Ok so I picked up the new kit from Oreilly's this morning and it fits perfect. Here is what I've learned according to the catalogs: 81/82 BRAT RELEASE BEARINGBearing Inner Race Bore Diameter (in): 1.377999Bearing Outer Race Outside Diameter (in): 2.228 CLUTCH DISKoutside diameter 7 7/8"spline inside diameter 7/8"spline count 21 83/84 BRAT RELEASE BEARINGBearing Inner Race Bore Diameter (in): 1.5748Bearing Outer Race Outside Diameter (in): 2.539 CLUTCH DISKDisc outside diameter 8 7/8"spline inside diameter 7/8 "spline count 21 85/86 BRAT RELEASE BEARINGSealed Self-Aligning typeBearing Inner Race Bore Diameter (in): 1.305099 CLUTCH DISKDisc outside diameter 8 7/8"spline inside diameter 1"spline count 24 Link to comment Share on other sites More sharing options...
Gloyale Posted August 24, 2014 Share Posted August 24, 2014 85/86 BRAT RELEASE BEARING Sealed Self-Aligning type Bearing Inner Race Bore Diameter (in): 1.305099 CLUTCH DISK Disc outside diameter 8 7/8" spline inside diameter 1" spline count 24 This is incorrect. None of the 4spds ever had a 1" (24 spline) input. the 83+ Ea81 4wds all us the 225mm(8 7/8ths) with the 21 spline(7/8ths) input shaft. EA82's started in the US in 85.......that's why the listings get screwy in the overlapping years from 85-87 (89 for hatches). Link to comment Share on other sites More sharing options...
TIMBERTIGER Posted August 24, 2014 Author Share Posted August 24, 2014 Clutch is installed and she flys down the road without a hitch! Gloyale,the listing in the catalog must be for an ea82. I think you're right. The catalog must not take into consideration that the BRAT didn't change with everything else. Link to comment Share on other sites More sharing options...
Gloyale Posted August 24, 2014 Share Posted August 24, 2014 the listing in the catalog must be for an ea82. I think you're right. The catalog must not take into consideration that the BRAT didn't change with everything else. Excactly. One reason I can see is that subaru Imported ALL of their cars in 85,86 as "L" models specifically "DL" or "GL" or "GL-10" models...........All of them........XT's, Brats, hatches......and EA82 wagons, coupes and sedans.......all technically are "DL" or "GL" or "GL-10" primarily........then submodeled as XT, or Brat, or wagon.....whatever. And to top it off both of the engines types that SHOULD be able to be used to identify each platform.......are 1.8 with the same bore/stroke so there is very little distinction in the catalogs.......sometimes they will ask OHV or OHC?.......which is like asking EA81 or EA82? In 87 the XT became it's own model..so parts get SLIGHTLY easier to find for them..but that's about it. So that leaves 85,86 as the WORST possible years to look up parts for.........so many variations........2 completley different 1.8 engines........4 different fueling variations..........I don't know what I would do without my factory 85 parts catalog 1 Link to comment Share on other sites More sharing options...
jono Posted August 24, 2014 Share Posted August 24, 2014 (edited) yeah the 24 splines stood out as wrong ! You only found that detail in some records, not actually supplied to you then ? The same listing parts confusion exists down under with after market stuff. Genuine is no hassle there is one measure not included in parts listings, but helps to decipher out of unidentified used clutch pressure plates kicking about - it is the size of the hole in the doughnut of the finger tips amongst the mix of 200 and 225mm stuff. Good to see you are sorted for a while.Maybe post up the succesful brand and part number and diameter of your clutch in one sentence?

TIMBERTIGER Posted August 24, 2014 Author Share Posted August 24, 2014 Jono, I actually bought the kit for the 86 originally and it came with the 24 spline. Lesson learned. Here is the link for the clutch I ended up going with: http://www.oreillyauto.com/site/c/detail/PTQ5/KF47501/01351.oap?year=1984&make=Subaru&model=Brat&vi=1267725&ck=Search_01351_1267725_2532&categoryRedirect=01351&pt=01351&ppt=C0015 Link to comment Share on other sites More sharing options...
