Tnx folks
Running for the moment at 20 bar pressure @2400 rpm. The movements are signifacant faster than the original setup. Maybe a little bit to fast if you compare it to scale movement, and much stronger. The bucket is a copy of "scandinavian" style bucket. The original cylinders are no good. Poor machined on the inlets, so it is diffucult stop minor leaks. I use loctite 243 and som thin gaskets, but it is not good enough. Looking for 5mm "dowty" sealings, but I have not found it, yet... The cylinders seems to function nice still. Have not tested it in the field yet, so time will show
Bought the hydraulic setup directly from Premacon in Germany and paid ca 450 euros for the 3-way valve, pump, coupling and some hoses and niples inclusive freight.
