N/S Windscreen Wiper Falls off!!!

[Benjamino]

Hi all, just a part query...

My N/S Windscreen Wiper keeps coming off when in use, I think the actual toothed round thing the wiper arm goes on is worn as opposed to the wiper arm. I just wondered if anyone can confirm if this is the correct part before I order one please....

It's for a 300Tdi by the way

No.
The splined bit is called the wiper arm adapter.
Is the adaptor coming off with the arm? Or the arm coming off but adapter stays on?
Adaptor is held on with a small bolt and is cheap to buy as are new arms.

shiny bolt on mine holds the adaptor to the D spindle.
Spring clip holds arm to adaptor.
New adaptor and arm, both cheap will fix it.

I was just driving home the other day and spotted a wiper and arm on the road,picked it up thinking that's lucky looks like a landy one.Handy to have a spare. Oh it's mine.

Exactly what I did, except I was tight and didn’t buy a new arm - I just tapped the existing one for a grub screw

Flossie - the adaptor stays on - it's just the arm coming off the toothed spline

Ok - guessing this might be the badger if anyone can confirm please...?

Yes, that's the one, I'd get a new arm too so it's all nice and tight.

Fank you!

I would get some releasing fluid on the bolt holding the adaptor on whilst you are waiting for parts to arrive. They can seize in/round off and snap.
I retapped mine to M4 or M5 so I could replace the unf(?) Standard bolt with a stainless steel one shown in my pic above.

Not having anything else to hand and knowing I had a, long drive in the rain the next day, I put some Metal filler in and pushed it back on. . Ten years later it's still there..
