Thread: Wierd bolt heads on crank

Aren't they standard 12-point head to which a standard socket will fit?

Or do they use Torx?

If they are the same as the TD5 they are a star shape. You can use a normal socket on them.

Thanks

brave man. It's not something I'd be game to trust.......

Could you download a picture or do an accurate drawing of this "weird" looking [to you] bolt? .......or is it a screw??? ......so people at least have an idea as to what it looks like?

Has it got a 12 or 6 point head? .....is the head "recessed", by any chance?

By what means do these bolts/screws "retain" the crank????? ......do you mean the 10 14mm main bearing cap bolts?????

same bolt as a 300Tdi, standard 12 point head. As Ron suggested, just use a 12 point socket.
And again, I'd be using another crank. They are only cast, not forged.

cast can be welded if done right ?

What has happened to the crankshaft that it needs to be welded? Metal spraying or hard chroming may be a better alternative.

Isn't this the one where the keyway is buggered? I wouldn't have a problem welding it in this instance (if the welder knew what he was doing).
