They got the same dimensions the ES 175/1-rod has. The only difference ist the bearing of the gudgeon pin. Original a bronze sleeve is installed but the TS 250/1-rod got a neadle bearing. Additionally the TS 250/1-rod will be delivered with two bronze dishes, wich won`t be needed in the ES 175/1. Ask him for new genuine arts, he also got genuine connecting rods for the TS 250/1.
http://mzsimson.de/index.php/deu/_/_/cf ... 81abe18/?_Please don't try replica connecting rods of the TS 250/1. Often they are signed for TS 250/1 but got a drilled crank pin in the big end bearing. These crank pins schouldn't be installed in a ES 175/1 because they will cause high engine vibrations.
Christof, thank you for your very detailed reply. It is most helpful. I need to ask some question to ensure I have everything clear.
So, I can use an original TS250/1 connecting rod, but you do not recommend using a replica connecting rod because they have a drilled big end crank pin and not a solid crank pin. Is this correct?
An original TS250/1 connecting rod will not have the correct bronze sleeve for my piston gudgeon pin. Will the needle roller bearing fit my gudgeon pin? Or will I have to modify the original TS250/1 to accept a bronze bush which will fit my gudgeon pin? If the needle roller bearing fits, then that is very good news.
Is this an original connecting rod kit, or is it a replica? :-
Thank you for any help you can give.
