My pop out just failed, it makes the circuit when it is about half way out but opens when the cylinder reaches the full out position. Is there any help out there for these problems? I tried search but got nowhere.
On the later style like you have I use a small very sharp chisel and carefully work back the crimp until I can pry the back cover off. Once that's off you should see the problem and it should be easy to work on.
The last one like this I worked on was loaded with graphite, which I cleaned out and only used a light coat of grease on the moving parts.
