My wiper motor is missing the securing nut (actually it was missing a few things, but I've managed to make one goodun from bits and pieces).
I've been informed that the nut is 14mm across flats (can anyone else confirm that?), I've measured the thread pitch which is very fine 0.75mm at M10. The spares suppliers want a few bob for new nuts, and they only seem to be available from Germany, so I thought I'd machine my own, but from stainless steel, so they'll stay rust free. I've ordered some HSS taps, just need to get some hexagonal bar to machine them from.
Anyone else interested in these? Can make a few an knock them out for a couple of quid.
-
They fit many other cars. Slightly special and irritatingly often not where the wiper motor is! I would go for a few. More than a few if it aids price/sourcing.
-
Well I will make as many as I can part off from the stock, or as long as my tap stays sharp (stainless steel is rather hard on tools).
-
What grade are you using out of interest?
-
303. Not as good as 304 or 316, but easier to machine. Will still be better than plated steel nuts.
I would also wipe a bit of grease on the nut and/or thread to reduce any chance of galling.
I could also make them from brass, but I have concerns that some would strip or cross thread them.
-
Good choice. I turned some 316 earlier this year and it was very chewy!
-
316 is handy if you live by the seaside. But the other grades are perfectly adequate for normal climes and especially for trim items.
-
I have had plated brass versions. But the thread is definitely best lubed up. I normally clean the thread out and try the nut first, in case there is damage.
-
Didn't the nuts have a trim piece/cap taht went over the top and sealed the shaft from water ingress?
Like these-

I have only ever seen the cheap thin aluminium cap which has a rubber seal , it's always done the job as have the original brass nuts - all original and will last far longer than some other parts of the cars
-
Well the thing is, I have neither. I didn't know the nuts were brass, the ones I've seen looked like steel, so I guess they must be plated. Regarding the caps, some I've seen are aluminium, others are brass, but again very difficult to obtain.
It always seems to be the little widgets and nic nacs that are the hardest to obtain. I think these are the last parts I need to source for my car.
-
Perhaps they are steel ? The British ones are always brass . Pretty sure I have German Bosch nut and cover in the garage - you are welcome to them if I have
-
Thank you that would be very useful.

I am away up north this week Thurso this morning , Lossiemouth today and Aberdeen by Thursday/ Friday . PM me at the weekend to remind me eh ?

The spindle cover pictured is as used on Bosch. It certainly appears on the Treinkel so equipped; in ali alloy. Not so sure about Isetta. The SWF used a thing that looks like a tyre valve cap. I use one on the Trienkel unit to as one seals the thread, the other the spindle. Either have an associated rubber seal that attempts to prevent water getting in passed the gap. Now it maybe that SWF use brass nuts and Bosch steel, or vice versa. Without looking at my box of dead motors awaiting referb I cannot say. Like all parts there is always the chance of spec changes and budget downgrades on materials.
-
Just went out and looked at mine, it has a plated steel nut and no fancy cover. Not saying this is correct.
Since I have owned the car I've been slowly correcting all the mistakes and bad workmanship inherited from the previous owner. Still have some way to go!
-
So it is no longer a Brighton BMW? Sorry I will go away now.
-
Wot you want me to take the badge off?
-
They don't look right without the blue and white badge.
Has your car got an original wiper(s)? I know a lot of owners tend to fit mini ones.
