Das MZ Forum für MZ Fahrer

Hi guys!

This is my first post and I am excited to be part of this forum.

I live in Cuba and we have here a great ETZ community imported on 80's.

I would like someone help me with an online address where I can find my first reparation for my ETZ. My current Pistion (Kolben) is standart and I need a 69.45 new one.

Please give me some link where I can buy this online, I would really appreciate any help.

This is what I need at 69.45 http://www.ost2rad.de/images/product_im ... _69.00.jpg

Thank you so much for any advice!

Hello cubandigger, @ welcome to our community
There are many spare part dealers in germany, where you can try to buy the needed piston, for example Guesi, he is a member of this community (link to his shop). But what I guess is, that the bigger problem would be the shipping to your nice country...

If I where you, I would contact Güsi. His page can be found under mzsimson.de. This distributor has some foreign customers and Pistons in your size (Type 69.6; First overize). Just copy 15172 and paste it in the Search-Function (Suche) of that page:

Thank you Christof and Ralle for your kind replies. The shipping is not a problem, I will ship to Austria. I am having a look to your links but the smaller piston I find is 60.50. Shouldn't be the first 69.45? I am right?

I'm not ETZ owner, but the discription of 69.50 piston is "1. Übermaß", translation is 1st oversize, so it should be the right one

The oversizes are always described with 0,5 mm steps.
So the first oversize is 69,50 mm.
The piston itself might be a 69,45, but the cylinder will be bored with 0,05 mm more to compensate the expansion of the piston when it is heated up in the running engine.
As the pistons are reproductions from a polish company ,which are sometimes said that they expand more than the original pistons(which are no more available) some people will give the piston more space to expand, for example 0,06 mm.
And you should bore the cylinder together with the piston, so the one who bores the cylinder can measure the exact size of the piston...
