A New Austin Seven Owner

[John Cornforth]

To underline what Reckless says, the cotter pins are of the "half moon cutout" type, not taper pins like a bicycle crank. The same sort of cotter is used on the fan spindle tension adjuster. Many folks have hammered away at these in the past in a doomed attempt to remove them with the kingpin still in place, at best they have got nowhere, at worst they have broken something !
