Hi all, I have a CWS aftermarket thumb on my Kobelco SK200-IV (ca 1998), and it's missing the ram. I can't seem to find anything on google that's drop in compatible. It looks like this was a CWS in-house built ram and they don't seem to be able to get me a replacement. They did send me an assembly drawing at least. Spec's: 50" retracted, 85" extended 4" bore 2.5" rod 2.5" pins 2500+psi The machine has "bolt-on" block fittings with o-rings for hose attachment, but I suppose I could have those changed pretty readily. I've found rams that will fit, mostly they seem to have a 40" stroke and are 46-48" retracted, but they all have pins that are 1.5-1.75". I suppose I could bush them if it comes down to it. Any ideas? Thanks in advance!
