Delayed retirement.. again. A conversion...

[furriegurrie]

It sure does look like a crack, I wondered about that too!

[white exec]

no chris.. A bit of crap....

I hope you're right.

Looking again chris., I do NOT think Im right, it looks it to me too.... hmmmmm...

[white exec]

Is the box still off? Thank goodness it's been spotted now.

[citroenxm]

Oh yes, ive not rushed that quick, I need to order a crank seal before it goes back together.... now I know theres no endfloat!

[Gibbo2286]

I've seen a mark like that before, when a mechanic had used a cold steel chisel to split the worn starter ring off.

[mickeymoon]

Surely that's a crack? The line of the flywheel is out too.

Yup, it is.. WELL SPOTTED guys, but damm well annoying! If its not one thing its another!!

CHEERS !!

The starter teeth (presume those on the right) look damaged at that point, too.

[Hell Razor5543]

Think of it this way. If it HADN'T been spotted, and you had put it all back together, how long would it be before it started causing problems again?

[citroenxm]

Absolutley James, I completely appriciate the spotting of the said offender..

[Hell Razor5543]

Maybe that damage is what caused the flywheel to start scraping on the block.

[citroenxm]

James the car was an Auto... This is a Manual Gearbox flywheel that was bought and sent with the manual box thats going in! It was only wrapped in black parcel wrap.. It was the Auto box "flywheel" that has damaged the block. There is ZERO contact between this one and the engine.. (See previous Posts)

[Hell Razor5543]

Oops, sorry, my mistake.

[white exec]

It takes a bit to crack a flywheel.
Ignoring a freak occurrence like contact with a sledgehammer, or being caught between the bascules of Tower Bridge, what could cause that?

One possibility: Engines often come to a stop, when switched off, in exactly the same rotational position. It used to be the cause of severe wear at one place on the starter ring, before pre-engaged starters took over.
In the case of the photo above, with damage on both the starter ring and on the timing-pulse teeth opposite, it looks as if the starter pinion might have overshot, with considerable force, and whacked that big block tooth to the left. The force available from a starter motor is massive. Maybe a starter motor badly fitted, or a wrong/substandard replacement. Maybe.

Even some tw*t with a crowbar might succeed in chipping off a tooth, but to split that thickness of steel? Whatever did it, it must have been clouted with some force.

Might be one for metallurgist John?
