What the **** is this? Is this slot meant to be on the crankshaft or has some bell end cut something off with an angle grinder and damaged the shaft?

It's a woodruff key slot.


EDIT
I think! Now that I've enlarged the image I'm not so sure.
 
some bell end using a slitting disc:)

Right that’s it, everyone else that’s had their hand on the landy is getting a slap.

Probably doesn’t make much of a difference but as I’m keen to only have to do this once I’ll get a new one, unless I can find a decent second hand one? Anyone?
 
if I could put in a slot that square I'd be well impressed with myself. looks like it was put there when the shaft was machined, oil channel?

That’s what I thought initially but is James Martin says it ain’t meant to be there then it ain’t meant to be there
 
I would probably wait and see what the rest of the crank is like and if it needs grinding then get the machine shop to weld it up and turn it back when they grind the bearing journals.

Yeh that’s a good idea. Better than £350 for a new one
 
Disaster!

When getting the block off the engine stand it slipped slightly and I’m guessing one of the sharp gasket edges probably the sump or head cut through one of the lifting straps. It fell forwarded, landed on the crank shaft (which is a blessing as I’ve got to change it anyhow), then flipped over and landed on its side on the legs of the engine crane. If my neighbours heard the obscenities I was screaming they’d never talk to me again.

I’m so angry at myself for not having at least a back up strap or using a chain. Thank god no body parts were underneath. If that landed on your leg you’d bleed out into your femur. I’d checked the lifting limit and even jumped up and down on it when it was a few inches off the ground to double check.

Amazingly none of the gasket matting surfaces got damaged. And the way it fell used up a lot of the force. Looks like I’ll have to send the block off to be pressure tested. Very domoralising in an already expensive project. I wonder why I bother with this bloody thing.

You have an inquisitive mind that has a thirst for knowledge and learning something new ;)

Well, at least you didn't get hurt and it only damaged something that you were going to replace anyway, it's all a learning curve, I had a shackle snap on me when I was refitting an engine once, it had a hairline crack in it that I hadn't noticed and it went with a bang, cost me a new sump pan and oil pick up pipe, luckily it wasn't hovering in the engine bay or it could have taken out some pretty expensive bits on it's way down :eek:

As in the shackle had a hair line crack? You’re right, no such thing as error free learning! Just wish I’d do my learning on less expensive bits of the vehicle.

Just that feeling of one step forwards, two steps back does my nut in!

Aye, focus on the fact that you were not hurt. Could have been a life game changer!
I'd be a tad concerned about the main bearing housing integrity. How far did it fall?

Doing such a complex job you have to expect set backs. That's easy to say and much harder to accept as I know from personal experience. The thing is though, all of us on here will know that, so you are in good company ;)
