Aaargh! I broke the (alloy?)shaft that is attached to the black lever/knob mirror adjuster. I couldn't get full adjustment and I pulled it too hard and now the ball' n' chain is giving me shit! It's embarrassing as I'm always on at her to take more care LOL.

Anyone know if it's a separate part or am I up for a new mirror assembly?

Cheers!

I need one too, I hope it does come as a part on its own. The "t" on the end seems to latch onto the shaft...

If you only broke the handle, you are in luck its replaceable. Now if you broke the internal adjustment level inside, whole mirror replacement, ask how I know. I happen to find a used one on E Bay for $15 LUCKY ME
And Im not even a HFT like you, big girls down there eh?? Funny

I did the same thing a few years ago. Seems that one of my kids was putting out the garbage pail and bumped the mirror as he walked by. As you know, it is spring loaded and should have returned to its home position but did not. I got in the car the next day and couldn't get the mirror to adjust to the position I "know" I could always get it to. SNAP, and the handle was in my hand. So once you have replaced the lever, make sure you lube the pivot points on the mirror housing so it will return properly when bumped in a parking lot or in your own driveway.

Not having seen the assembly off-the-car... Im going to suggest that you will need to press out that pin b4 anything 'good' happens.

:)

The internal mechanism is cast alloy so gently, gently. The pin is pressed in and has a washer that slots over it and the pin (end) is then flattened out to lock it; can't remember what they call this type of arrangement.
Anyway filed off the washer to take off the control arm and fitted the new one but couldn't get the washer to lock on.
Ended up breaking another arm:mad: so taped and wired it. A real backyard hack job.
At least now from inside the cabin it looks as if it works as the lever is in place.

Told her she'll have to adjust the mirror the way we did it in the 'old days', wind the window down and push the mirror with the fingers. LOL.

The end!

Could you not use a threaded screw/nut arrangement?
Perhaps one with a beveled head and a nut shaped like the end of a rivet?
Dunno what they call them, but have seen them before.

That was Plan "B" but the pin/shaft is as tight as a press fit and couldn't remove it; can't bash away at it as parts are cast alloy and not much room to manoeuvre.

A job for specialist tools I reckon. It must be possible 'cos the arm is available as a spare part.

At the end of the day I don't care 'cos it's not my car:D

The easy way to do this repair is to visit your local you-pull-it yard and remove the entire 3-piece adjuster from a donor. It's a very simple process:

1: remove mirror from car (3 screws, 1 wire)
2: pop out glass from mirror (1 wire)
3: remove small straight screw at base of adjuster (ball)
4: slide out assembly (may need to spring open the mirror)

Reverse the assembly to install. I picked up 2 donors Saturday and did the swap Sunday on my 300D. Id' advise you that before installing the new part, put some good penetration lube and then oil on the two hinge points. Plus a bit of grease on the mounting ball (back of mirror). Feeling how smooth and effortless it now moves I understand why the originally broke.

300D-91 has it right! the W124 or c124 coupe mirror uses the same internal assemmbly parts so this is the way to go. The Coupe mirrors seem rarer so this is good advice.

Yep it is good advice- and I would have done so if I lived in a capital city, however I'm 300 klms away from the nearest one. A mirror assembly is on my shopping list though for when I next visit the big smoke.
