I have a 1275 engine with some fairly severe damage to the nose / taper of the crankshaft. My vote is that it's scrap (though I have been very tempted to carry out a Belzona repair (!). What's the verdict here? This is purely to convince me that I need to pull my finger out to overhaul this engine and get the mini back on the road!

 

Thanks in advance

I've scrapped cranks with less damage than that one! 😵‍💫

That’s trash.

 

or a very expensive repair.

That one is karput.

Thanks for the confirmation.... I have a spare crankshaft. And so the process begins!

I couldn`t help but think about a 6kg chunk of metal with lots of teeth spinning at 6000 rpm letting go right between you legs

It happened to me when I was grass tracking.
It didn't come off but it was spinning on the taper 😁
They don't half rev quick with no flywheel on 😁

I was at a race meet, I think it was 1980 (?), and one exploded. Took the guy's foot clean off

Well,, wasn't really clean,,,

Needs to be pulled out the engine either way. Machine shop would be best placed to let you know but seen worse repaired...

As above.. depends on the depth of your pockets...

lol, I know the feeling as the same happened to me with a Rover Cooper that had had a clutch replacement at a main dealer a few weeks earlier.

It was raining and I was in a rush to get home from work and at first thought it was spinning one wheel on the nasty Falken tyres but then it sounded like an automatic so I pulled over and opened the bonnet with the engine idling. I could hear an unfamiliar noise around the clutch housing and then the flywheel fell off   

I got a new flywheel and keyway out of Mr Rover and did the job myself and luckily the crank taper was unmarked

I remember changing a clutch on a mini I had picked up that had a DIY lightened cast flywheel that was 5/16" thick and drilled to death, it didn`t go back on.

Funnily enough it pulled better with the standard replacement.

I think it is fair to say that you couldn't chew a crank, like that, with NHS dentures.
