inspect yourself and then instruct them to go ahead or not.

If a 'crank shaft nut' got 'cut' and a piece was 'stuck inside' wouldnt you have noticed strange sounds from the engine?

Like everyone says, check this out yourself.

Ok, I just got back. This is way beyond my technical understanding. But I'll try. The crank shaft bolt got broken and the remaining piece is still stuck there. See the center of the flywheel here...


As a result of this the pulleys get out of line and cams skip a teeth and everything goes out of whack. I can't get any technical than that.



They had opened the top of the engine, and were trying to see how many cams were off, something like that.

This is the service center: Abharan Motors

The Works Manager is Nagraj Kamath, he said he will try to do his best to deliver this ASAP, current estimate is two weeks. He is also trying to find out whether this can be covered under warranty. He said this is a rare case and no exact reason can be attributed for failure of this bolt. Sounds like an manufacturing defect to me.

So there is visible damage on the cam ?? Is the crank allright ?? So what all did they tell you they would need to replace ?? Also are the spares readily available ?? If not they will not be able to stick to their commitment of two weeks ..

I am sure this will be considered a manufacturing defect and would be considered under the warranty.
These are the worst fears of any car owner.. what is the extent of damage? any damage to the pistons, cylinders since the cams were off? how much would be an approximate cost to repair such damages and why 2 weeks for the repairs?

Looks like the both has sheared off a long time ago does not look like a fresh break to me. However the cam does not look damaged. The key part that could have been damaged if the timing belt slipped would be the valves so doing a compression test would be the best approach.

The only reason I can attribute to that particular bolt failing is due to excessive torquing of the bolt when it was put on... Samurai was the timing belt adjusted recently?

This can only be either a faulty part or an incorrect installation where the bolt may have been over torqued. There is no way you or any modification you have done could be held responsible for this.

The car is now just over 2 years old. And barely a month outside the warranty period. I feel Maruti should cover the repairs under goodwill. Push them for this.

seems like a freak manufacturing defect.

my observations:

the bolt that broke was crank shaft pulley one right? and timing is controlled by timing belt which has separate pulley and belt/chain right?

if so internals wouldnt have been affected as in valves and cam etc, am i correct on this?

and the pic also doesn show of any evident scars.

i guess a good dealer would be able to replace the defective bolt and crank (or machine the crank) and get the car back to its feet soon.

The last time it was done was in November as part of paid service, in the same service center. Yeah, it does look like a old break, even rusted to some extent.

Regarding damage, they haven't gone inside yet, they were awaiting my approval to proceed further.

Ok - my contact got back to me now - the price is quoted around 1000 bucks.


@Psycho: Will Samurai's car run as new after the repair/replacement of the problem above?

there shouldnt be any reason why the car wouldnt be restored to its prime if the work is done properly at a good garage which i gather samurai has access to. hopefully some warranty cover should also help him.

only the agony and the wait thats bugging.

No scaring - just an open straight-forward query
