I've got an 89 4Runner that the clutch stopped working on. My wife was driving it and the tranny lost it's grip and slipped for about a half mile. When I got there there was no burned clutch smell. There is absolutly no rotation getting to the tranny. I can shift through all gears with the engine running and not step on the clutch. The slave cylinder is fully retracted and there is a little play on the fork. I am at a loss, I have never seen a clutch fail like this. I took the two shifters off the top of the unit last night to see if there was any motion inside the transmission and saw none. I am about to pull the transmission out to see what is wrong but as I have never pulled a yota transmission I figured I would ask to see if anyone has run into this before or has any ideas to fix it without pulling it. Thanks. Scott
 
It feels like it always has. I checked the function of the slave and it is working.
 
Get out your tools! If it slipped for a half a mile it's toast. Make sure you get a pilot and throwout bearing when you get the clutch kit.
 
Wouldn't there still be some rotation of the input shaft? Enough to maybe grind when shifting without the clutch? Thats what gets me. There is some substrate that the clutch material bonds to that should still be there. There is no noise. no grind. I guess I'm going to pull the unit when it gets cooler. I was hoping for a majic bullet from the Gurus. Thanks. Scott
 
GET OUT YOUR TOOLS LIKE THE MAN SAYS....NO MAGIC BULLET HERE...........

:beer:
 
Also plan on having the flywheel surfaced. It's probably got some hot spots on it.
 
Thanks again. I pulled it last night and the disc is beyond toast. No material at all on the pressure plate side. Is there a trick to maneuvering this beast back into position? Or just perseverance and luck? Thanks. Scott
 
Just preseverance. Got someone to help? it's much easier with two people. One to watch the front end and steer and one to push.
 
One thing that helps....
Take some 17mm head (m12?) bolts and cut the heds off. Thread them into teh holes on teh tranny... then use them as guides to line up w/ the motor bellhousing. Once it's really close, untthread 'em w/ double nuts one at a time and replace w/ the real bolts, using those to pull it together.
Wooden dowels work too.
 
Thanks, great idea. I've got everything set up. I welded up a saddle for the tranny tonight. I wasn't happy about the length and instability on my wide saddle jack. I think with the bolts and the saddle it should be fairly easy tomorrow. I'm training my son to be a gear-head. This is my son's first clutch changeout. He's 13. This is a good lesson on why not to slip it too much. I appreciate the insight guys. I have never seen one go like this. Usually in my experience there is ample warning.
 
Heck I've seen brand new clutches blow apart before they leave the parking lot on the first road test. Just a bad pressure plate is all it takes.
