wiper motor arm

[Dickie12]

Can anyone help me please I have a problem with the wiper motor on my 197,
The brass part that is attached to the spindle on the wiper motor will not stay it keeps on slipping,
Does the brass part have splines on it to go round the spindle on the wiper motor,
Or do you just tighten up the nut on the spindle to stop the arm from slipping.
Please see some pictures as well.
Thank you anyone for the help

It's definitely a splined shaft, if your wiper arms siezed it might have shagged the hole!
