Hi 

 

 A friend of mine is trying to mend my Landeron 48 chronograph movement.

He has replaced the flyback lever but we are having trouble locating the pushers ..

anyone know the part reference please?

Do you mean the pusher buttons or the pusher pieces/levers?
I attach some information of the Landeron 48 and its pusher parts.

Item 2

Yes item 2 is the flyback lever (8180) for the stop/reset action and the operating lever, item 8, (8139) to start the chronograph.
The hammer (8219) is what they manipulate. The hammer spring (8350) is what operate the hammer itself by pushing into the cam slots in it.

Most often when you have a poor action with the pushers the culprit is the fly-back lever spring item 7 (8340). When this isn’t working correctly you will not have a snappy transition to the stop mode. The hammer spring will just stick halfway down on the cam .

When putting the pushers in you will see they have two different lenghts on the pin, one shorter for the flyback lever and one longer for the operating lever.
