Topic: Loud POW and clutch no worky

[TATER]

 This 84  4 Runner is startng to piss me off.

Ever since I bought it, I have been chasing a vibration. Did rear wheel bearings while doing gears. That helped. Did u-joints. That helped. Then noticed that 4th gear had a little noise between 3K rpm and 4K rpm. Wasn't to worried, but vibe continued. So I'm taking a weekend spin to enjoy the weather, hit about 70 mph and POW. I shift into nuetral and the clutch goes to the floor. A roadside look under the hood finds the Weber aircleaner gone. Whaaa? A quick hike back to point of loud noise, and parts of cleaner are scattered about. I was thinking backfire. Get back to truck and look again. To my suprise, a crack all the way around the bell housing.

  So I summise that the clutch explodedwhich pushed the trans back some.


Will this trans be any good if the bell housing is swapped? Or does an exploded clutch mean a wasted input shaft also. I am seeing more fluid than before.

Ouch! sounds like a bad deal.  Your input bearings are most likely toast as is the input shaft possibly.  A catastophic explosion like that may have taken out the flywheel as well, the rear main seal could have gotten wiped out with a bad vibe for an extended period of time too.  Im sure Marlin will have some more/better knowledge of what this could entail to fix as well.

I have seen a flywheel loosen & shatter from vibration. Took a nice chunk out of the bell housing.

there's a lot of aftermarket scatter guards available for american transmissions, but never seen one for a toy.  i've heard some real horror stories about flywheels blowing up

 The flywheel is more than likely OK. I can start the engine .


  I have a line on a trans w/ a bad bearing. Do a rebuild and I'm good to go. Only problem is that I have never even opened a trans before. I really looking for a good used trans for under $200. Damn local junkyards want $800 for one w/ 90 warrenty. A $150 rebuild kit on the trans w/ bad bearing and I'm good. Thats assuming I dont mess it all up.


  Any rebuild links? I gotta FSM, but some "whatch out for this" insite would be nice.

got i hate it when breaks hearing that brings back bad memories

  I got the damn thing off today. Clutch fine, other than normal wear. Most of the bellhousing bolts were LOOSE. I believe that a combination of loose bolts and all the other vibrations along w/ dead leaf springs conspired to leave me stranded.

  So.... a junkyard bellhousing should get me back on the road. This is temporary at best. The input shaft has some up and down play.

  I got 2 people who are willing to give me cores for rebuild. I'm still wary of a home rebuild. A local trans shop told me that they charge $165 just to crack it open. Then only replace anything thats broken or worn out.

Where are you at, I got a bell housing or 2 in my basement.
Also look at your crossmember, has it been bent? What about the braces from your engine block to the bottom of the bellhousing.

 After a while of hitting your crosmember on things it can get bent and start to pull on the engine. Then the motor mounts can only flex so far and the pounding of every hit goes somewhere. if your lucky the bellhousing breaks. If your not youre block cracks. I have done both.

 Here is some fun reading. there is part in it about my bellhousing.

  Thanks for the offer, but one of the rebuildable cores is donating a bell housing.

Interesting story. Its sounds like days I have had. I have been know to be "That Guy". "That guy" who broke something. "That guy " who forgot his Hi-Lift. "That guy" that w/out a spare...LOL
