I have this older 84 GL SW 4x4. The Transmission went out so I decided to fix it the right way this time. Rebuild Transmission, New Pressure Plate, New Clutch, and the Flywheel got resurfaced (new bearings too). In the past I've always gone the cheap way and just bought a new clutch Plate with no real problems. However this time, I get it all back together, and my clutch will not stop slipping. It's so bad, I can start it in 1st gear and a turtle would beat me in a race. Made the adjustments on the cable with not much luck. I've spent a lot of money in that little car and the car is a beater, but I love it!!!! I'm getting depressed:confused: because I don't know what I did wrong. I can't seem to fix it and I don't want to take it a part again if not needed. Any suggestions out there? You think the flywheel was maybe resurfaced too well? Please Help!!!! Gas is too expensive not to drive my Sube. Thanks:)

The flywheel may have been turned too deep - you might consider just getting a new flywheel - they aren't that expensive. A junk yard model would probably work too. I generally don't resurface mine unless they have grooves or pitting. I rought them up with a bit of sandpaper and put em back.

How did you adjust the cable?

I adjusted the nuts at the end of the cable. I tighten them all the way, loosen all the way, mid-way and i got the same results. It feels like the clutch just isn't grabbing enough. A manual says it takes 30 to 40 starts for it to seat. Whatever the case, it's not working. Thank You

If your seals etc. are right and there are no leaks leading to slippage, then I also say that your flywheel was resurfaced too deep and you cannot compensate by adjusting the cable anymore. If the cable is adjusted correctly, then its time for a new flywheel.

If your clutch is slipping, the only way the cable could be at fault is if it was too tight (as though you were pressing on the clutch pedal when you're not). To test for this, disconnect your hill-holder cable and see if you can easily wiggle the clutch fork a little by hand before the throw out bearing hits the spring fingers (you should be able to).Otherwise I see two possibilities.

  • You got a "rebuilt" pressure plate with very weak springs. (not so likely)
  • Your flywheel only had the friction surface turned, or at least had it turned deeper than the pressure plate mounting surface. (much more likely)
#2 above will position the pressure plate too far from the flywheel friction surface to allow proper clamping of the disc in between. There is a spec as to how far apart these two planes are supposed to be, and a knowledgable machinist should have checked this. Sometimes they just assume that your flywheel was already in spec and take the same amount off both surfaces, and that will usually work. The worst case is if they didn't cut the outer surface at all.

In any case, it unfortunately sounds like you're going to be pulling it apart to fix this.

There are LOTS of good wrecking yards around. I'd suggest going up the highway a bit to Belfair and using either Belfair Autowrecking or Airport Autowrecking 2 (the import yard next to the Bremerton raceway). I believe there's a Pull-A-Part down in Tacoma, too. If you want, I'll poke around in the two yards I mentioned and see what I can find. If there's something good, I'll let you know and we can meet up. I'll bring a flywheel down to you.

Have you readjusted the hill holder cable? I could see a mix up if this was an '85-89 EA81 vehicle. But there is only one measurement for the '84's. Check your hill holder to verify that it is releasing the clutch as well.

Qman, out of curiousity what is the difference between the '85-'89 EA81 hill holders and the earlier ones? I never noticed any difference between the one on my '83 2wd sedan and the one on my '88 4wd Hatchback.

I had the exact problem and this was my issue. It might not be yours but it's worth checking. My clutch cable was bad . I put a buch of new stuff into clutch but it still slipped. I thought all kind of bad things. I even thought to check the cable by dis-connecting it and pushing pedal in and out. That didn't work. It wasn't until I pulled cable all the way out and manually moved it when I realized it was binding severly, a 25.00 cable and its never been better. I now have a complete spare unit because of the things I bought and replaced tryingto fix it. Check it out before you pull the clutch apart, ya never know?

Make sure your new clutch isn't made for a 0.825 inch step flywheel, and the flywheel happens to be maunfactured/machined with a .900 inch step. I often see this in Subaru as a cause for new clutch slipping problems and/or clutches that are weak and only last a short while. There is one in my shop right now. The guy bought it cheap because of short-weak clutch life over and over. Wrong clutch for the flywheel. 0.075 inch makes a world of difference in pressure plate compression. I believe it is possible that people are comparing the old clutches to the new ones and if it is the same then they are installing another wrong clutch. I think a simple solution to this would be for the manufacturer to stamp the clutches with the step depth. virginian97@yahoo.com
