Whilst driving home last night in griff...Heard sudden bang followed by a thud, then all warning lights came on, and battery no longer charging? Pulled over and found bottom crankshaft pulley lying on floor of chassis, with ancillaries belt hanging off??
After inspection today, found pulley bolt had sheared in two...Hear this happening occasionly, and was going to change mine as a precaution too late now, but engine and car okay, just need new belt and bolt...

But a warning to check or change your's may prevent a motorway failure, like mine....

Sorry to hear about your problem, hopefully no permanent harm done. What can you do to check for this though? It's either broken or not; don't see what you could have found any warning signs short of taking the bolt out and putting it under a magnifying glass?

Cheers,

Ive heard of this happening before,although never experienced it on any of my previous Rover V8s.
Have had the unfortunate incidence of the screws coming loose on the Advance/Retard on the Distributor.
Happened on a track day last summer - resulting in terrible pinking - thought i'd lunched the engine.

Thankfully my supplying dealer , Christiopher Neil , kindly traced and rectified the fault FOC in the morning allowing me to hoon the car round Oulton in the afternoon.

BTW they also replaced a fried starter motor FOC, out of warrrenty,caused by me doing obout 20 laps non stop that afternoon .
Cant fault them.

I would in hind sight now, have removed the bolt and replaced with new one from TVR..But alas too late..However phoned TVR this morning, and parts guy said"Last time we had this happen had too change whole crankshaft" as bolt is hardened steel? News to me but i am sure with some persuasion the remaing bolt will come out? HOPEFULLY....My car is a 1996 P plate, don't know if this is a common fault for year or not?

Did you fit it yourself? It needs to be done up to a fairly impressive torque!

It's about 4 apprentices straining on a 6 foot bar while 6 others try and stop the car from turning. No idea what that is in lbs/ft...
