Wedico multi stage cylinder

[steamer]

I know there's been a few problem with these cylinders and I was wondering if anyone had one now that was in pieces? I have a new one to use on a D400e but I need to feed the oil in the rod end instead of the bottom. I know this sounds crazy but thats the way the cylinder is mounted in the ADT ejector version! Any pictures you might have would be great!
Thanks Rob

Sorry I can't contribute to this but I would love to see some close up pics of internals also. I've been wanting to make some and don't know how the scaled down version would be most effective on seals/stops. If i do find some pics somewhere I will get back with them.

each stage has what looks like 2 rubber cups one faces up one faces down
and you get air bound real bad if your not careful. on my dump truck I keep
popping one section and blow oil all over the cab. plus each stage weeps oil

bigford, when the cylinder pops a section is it still moving in the stroke or is it when it hits full stroke? And when it comes apart does it just shove off one of the black retainers between stages?

[bigford]

seems to happen at the first stage off the base and the last stage while still pushing.
it looks like they ran a pipe cutter around the very bottom of the tube and that's what
the black retainer locks into. I think if there was a clean way to bleed the cylinder
it would not happen as much
