screwed clutch or gearbox
Discussion
afternoon
Picked up the Cerb today after having the engine rebuilt and decided to drive it back up to Newcastle to help run it in.
250 miles later and I'm sitting on the hard shoulder of the M1...
Car started to feel weird, as if the throttle cable was sticking, car would over rev when stationary and using th throttle and it would take ages for the revs to come back down, when driving and taking your foot off the throttle, the car would take a second or two to start dropping revs.
I assumed this was a slipping clutch or throttle cable problem, then bang. Lost all drive, engine was spinning and reacting to the throttle ok, but it wasn't driving the wheels any more.
Coasted to a halt on the hard shoulder, with what sounded like the gearbox rattling around.
I can't select any gears anymore, but I can push the car around with the clutch depressed.
I didn't have the clutch or gearbox replaced when the engine was done.
Any ideas, is it likely to be the clutch or the gearbox? Where do the newcastle Cerb owners go to have their cars worked on?

if the clutch disengages drive it sounds like a gearbox failure .. were you in 5th at the time? 5th gear is hte fragile one, but usually doesn't affect the other gears so you cna drive the car home or to a garage .. until bits of 5th find their way into the front part of the gearbox casing anyway. I know one person who drove all the way back from le mans in 4th gear when 5th gear broke on his cerbera.
the throttle problem sounds completely separate and unrelated to this other failure.

trooperiziz - BAD luck mate ! 
Was chatting to Jo earlier & he mentioned you'd just got it back & had problems already !
As Joolz said, sounds like you have 2 problems, but the immediate one sounds like 5th has gone bang (I know 2 people that have had this happen to & your the 3rd) - if you've not driven it far, damage should be too bad. And it's all caused by a weak split pin holding 5th on (apparently)!!!

Bad luck. I would suspect the two faults are unrelated too.
The first does sound like a badly adjusted throttle cable, or perhaps its started to get cuaght n the sleeve. The second sounds more serious.
It has to ne gearbox related. You say the engine revs and sounds normal (do you still have the sticking throttle), so that must mean the flywheel and clutch assy are all ok, or at lease still attached. Can you select any gears? Even when the engine is off does the selection of gears feel normal in any way? How does the clutch pedel feel?
My total guesses would be;
Prop shaft gone
Input shaft from the engine failed
Gearbox broken up inside
But one thing i would do is get it back to the place the rebuilt the engine! The gearbox has to come away from the engine to get it out so they 'could' have not refilled it with oil, so check that out. Also get someone indepenent to look at it, if you can.
Remember you have at least 28 days warranty on all work carried out during the engine rebuild, not just the engine its self.

I was in 5th and was going to get the gearbox refurbished when I had run the car in as I had a crunching synchro between 1st and 2nd! Ah well.
I can't select any other gears though, so the damage is likely to be quite severe I'm guessing.
I'll get them to check the throttle cable routing at the same time.

Sorry to hear that.
Do you get any warning before it lets go? Does it happen if you are giving it some stick in 5th?
Looking through the receipt file that came with mine, it had a new gearbox 5000 miles ago (at 50,000 miles) and that was put down to low gearbox oil level. This was despite it having been serviced at the correct intervals.
Hope you are covered by some sort of warranty.
