Thanks for the comments , it is nice to know , that I am not alone with this so called problem . Main question is why DR made piston this way 🙄 . I simply can not accept , that needles are partially in the air and therefore connecting rod is stressed either left or right side . So , I am following Ritze’s idea and putting stuff around bearing . I happen to have a new Tomos connecting rod with 10 mm bush in the small end . I will take that bush away and cut two 3 mm wide slices of it . These brass “washers” go around needle bearing . If there comes some problems in the future , I will report it here .
I must some day read that Ritze´s personal page , it seems interesting , even though G translator is not perfect 🙂 ,
