Smoked clutch I think

[5B Steve]

  I tried to move the bus today ,she moved forward about 2-3 feet stopped, reverse 2-3 feet, when I went in to

gear again , nothing.   Did the clutch let go?  Tires didn"t spin.

maybe out of adjustment, but I don't see that short bit of moving as a way to burn up a clutch,
maybe stuck in neutral ??

The splines on the driveshaft slip joint may be gone, happened to me.

Probably the assist is hung up in a neutral position not letting the clutch engage

Probably the assist is hung up in a neutral position not letting the clutch engage

If that's the case, how do you fix it?

If the air assist cylinder was hung, the clutch pedal would be stuck on the floor.  Do you have a normal clutch pedal movement and pressure?  Can you get someone to press on the pedal while you look at the linkage on the gearbox to see if everything is moving right?  Are you sure you are getting it in gear properly?  Has the reverse solenoid hung up at all or is it operating correctly?  You can see the reverse solenoid and the top of the clutch linkage through the access panels in the floor at the back of the bus.

Just press the pedal without air if you don't have about 2 inches of free play on the pedal start checking beginning with the adjustment in the rear side door, the assist pivots and will hang in upwards position or the level position from time to time is what I find  

There is a bunch of linkage and circuital adjustments associated with the air assist fwiw that is where I would start JMO they never get greased

If the clutch failed, wouldn't it be almost impossible to get it into gear? Just another dumb question-it's past my bedtime.

Lots of ways for a clutch to fail but two of the most popular are for the friction lining to burn up and causes massive slipping.  If it can't engage at all, you could still put it in gear but you'd still feel the clutch spring there.  The other way (seen it on race cars but no idea on bus clutches) is for the center to rip out of the clutch disc so the engine is basically not connected to the input shaft any longer.  Without more information from Steve it's hard to guess what's happening in this case.

 A broken axle, stripped splines, broken clutch splines, all will generally make a lot of racket. More than likely the clutch is hung and is not engaging.>>>Dan
