Atmos 540 Question

[Karl Burghart]

I have a 540 in the shop. The owner decided to wind in manually as the bellows was getting weak. When he did this he way over wound it causing the pin to fall from the winding chain. From the Jerry Jager stuff I've read, he tells you to replace it in the link it came from. Is there a measurement like for the other calibers to check the tension? Thanks in advance.

Literature says 45mm spring length when installed. If the pin came out, quite possible the chain broke, as I cannot see how the bent pin escapes otherwise. I'd think you need to look in the motor for a link or a piece of the chain, then check the length of the chain if it was so stressed.

Thanks Ed. 45mm is what I needed to know. Thankfully the chain did not break.
