Does anyone know if the Loco LILLA 3.5" guage has 2 Links or just 1.The drawings and EIM write up are not clear…..

Maybe there is only 1 on every loco and i am showing my lack of experience here but hey ho you gotta learn sometime.

Just a bit puzzled as there are 4 eccentrics as well,Maybe it will become obvious as i progress but thoughts welcome..

Maybe you have sorted this already, but………

Lilla has two expansion links, one for each 'engine' = each cylinder & associated valve gear.

Each expansion link is driven by two eccentric rods, hence why you have four eccentrics. Each eccentric rod runs from an eccentric to one of the lugs on its expansion link. This 'blog type thing' of a similar (5" gauge) locomotive might give you a bit of help. 'October 2011' shows a reasonable pic of the valve gear, and the associated drawings under 'November 2010' might also be helpful.

Regards, & good luck!

Phil

If you don't ask .. you don't learn

The only stupid/foolish question is the one you don't ask !!
