Some questions

[NorbertE]

Zoli, the left side head is 7:1 (1,5 PS), the right side is 7,5:1 (1,8 PS)

I`ve never seen angle gears on Rh50 motors Only later on M-motors from Simson. I must ask.

[Zoli]

Many thanks Norbert.
I guess that this drive is a home made modification which I found in a purchased engine. Now I will test it!

[NorbertE]

I think also: homemade. But good work
And the Rh motor is with this parts a little bit quiet. I think so.

[Zoli]

This is why I am happy, and hope that I will enjoy it on my long ride to Kürbitz!

[Zoli]

Could anybody tell me that this type of engine ( with no lipseal on pedalshaft) could belonged to an SR 1 or SR 2 or both?
When was the lipseal introduced on SR?

Kann jemand mir sagen, dass diese Art des Motors (ohne Simmering auf Pedalwelle) gehörte könnte ein SR 1 oder SR 2 oder beides?
Wann wurde die Simmering auf SR eingeführt?

This angle drive gear is very interesting.
I wonder wich parts were used and is it possible to to it again?Is it easy to do or is some machine work needed?

I have found these parts in an engine which I purchased. When Norbert told that he saw this angle drive only on "M" engines I checked the exploded diagram of the Simson Star engine. It looks that it is very similar, the only question is to me if the taper (cone) on the crankshaft is identical to the SR one?
If there is a difference at the connection of the coupling basket and coupling shaft, it could be very easily solved by a special turned intermediate part.

Ich habe diese Teile in einem Motor, den ich gekauft gefunden. Wenn Norbert gesagt, dass er diesen Winkel fahren sah nur auf "M"-Motoren Ich überprüfte die Explosionsdarstellung des Simson Star Motor. Es sieht so aus, dass es sehr ähnlich ist, die Frage ist nur für mich, wenn die (Kegel) auf die Kurbelwelle Kegel ist identisch mit der SR ein?
Wenn es einen Unterschied bei der Verbindung der Kupplung und Kupplung Welle legen, könnte es sehr leicht durch eine spezielle wandte mittleren Teil gelöst.

I will try to combine SR2 parts with Star parts when I meet a friend next weekend.He has these parts.
Very interesting modification.

regards, Toni

[Zoli]

That will great! Please report your findings!

[Zoli]

Many thanks for the information Siebenson!

Cloyd.
How do you like this?

It looks very similar, but the basket is longer in the last pic.
Could be that it has to be modified to fit the SR engine.

[Zoli]

Here is the comparison between SR 1/2 and Star coupling.
The following modifications neede to fit the Star coupling to RH engine:
1. A taper must be machined into the small pignon.
2. An intermediate bronze bush must be used between RH coupling shaft and Star coupling basket.
3. The fingers of the Star coupling basket must be shortened.

Hello Zoli!

I just had a Star clutch in my hands one week ago and took some measurements.
The result was, that it cant be mounted into the SR engine without special machining.

Its pretty much a big engineering job to make it work perfect.
I wonder how the power and the caracter of the engine is with that big modification.

regards, Toni
