MZ/MuZ Riders

Has anyone in the UK got the steering bearing lock nut from an ES that they'd be willing to let me have for reasonable compensation? It's a M32 X 1mm Pitch, 7mm depth and is nigh on impossible to get hold of.

Would be lovely if MZ had considered using standard fixing sizes instead of inventing sizes just for one model of bike

are you sure about the 1.0 pitch that's the thread pitch of an old wv valve adjuster

i am finding bunch of 1,5 pitch in 32 no 1.0

You can buy M32 x 1mm taps and dies so it must be a standard metric fine. The nut is only 7mm thick so that`s the only way to get a reasonable number of threads in there.

Thanks for the responses.

Yep it's definitely M32 X 1mm. It snapped while I was undoing it (to my surprise; it was stiff but was unscrewing without much resistance). I jumped on eBay and quickly found plenty of m32 nuts with a 1.5 pitch but figured I'd just check with a thread pitch guage before ordering, which is when I realised I should have left it to soak in wd40 before going at it

I can find a couple of new old stock items from the usual European suppliers (which confirms the sizing), but since I've just put in a big order with ost2rad and had no plans to spend a silly amount on postage for a single nut, as well as Brexit now being a thing which I'm not sure as to whether that will sting even more on postage/import costs, I figured I could just put the question out there incase on the very rare chance that someone had a spare floating around that they would be willing to sell me.

I'm currently in the process of refurbing the electrics so if I'm lucky I'll discover a few more bits that need ordering which will at least slightly ease the blow on potential postage/import costs from the eu

Ta for the info.
Indeed odd for MZ chose such an uncommon size then - or maybe it wasn't in those days. Maybe it was Honecker's ideal size...

Good luck.

One on Ebay which confirms your measurements (not that i doubted you ) - https://www.ebay.co.uk/itm/Befestigungs ... SwF6dgAFuC
And another - https://www.ebay.co.uk/itm/Mz-Es-150-Nu ... Swqf5f41iw Shame about the postage costs!

The later MZs use a M32 x 1.5 stem and nut it seems.

Not to worry I make enough mistakes that it's only reasonable to be doubted sometimes!!

As it happens you may have just saved me (even if it was inadvertently). The top item you linked me to, I have never seen before during my trawl of eBay - you must have better searching skills than I! Now <£15 posted is a price I can work with; the issue was that I could not find anything below around £30 posted. While I didn't have a problem with the price itself, it was more the feeling that I was being robbed having to pay £30 for a single nut (naturally, knowing full well that I'd need to order something from the exact same site and pay the same postage again, less a month later)

But after all, would we really bother looking after weird 47 year old communist bikes if we didn't enjoy constant frustration and unreasonable prices for spares?

Ha ha. Progress of a sort then. Nothing else he has that you might need to soften the p and p blow?
I think i put " MZ ES nut" in the Ebay search.
Have you checked out the UK MZ riders? - https://www.mzridersclub.com/Welcome/

Nah, don't complain. Parts are available, and that cannot be said for other bikes/brands.

True - admittedly this was the first time I've really banged my head against the wall, more so when I could have avoided snapping the nut by being more liberal with the wd40 and leaving it overnight instead of being impatient.

For the most part MZ have been pretty good with standardised fixings, only other problem item I've come across was the armature fixing bolt, although once I figured out it was actually M7 and not m8 it wasn't impossible to find a supplier.

In other news I've had my lockdown project ES running really well for a few months now but it's in hibernation at the moment which I saw as a good opportunity to sort out the combination mains flex/corroded original wiring loom with a proper colour coded replacement. Should be able to get some photos of the bike up here soon and finally get some real riding in once it warms up.

Cheers for the help everybody
