How do I change the piston seal on a hydraulic ram (on a 15 ton JCB)?
Ok, so the simple "unbolt the rod end plate, slide out the ram and replace the seal" isnt quite what I'm looking for.
The ram is on a JCB excavator and holds probably 10 or 20 litres of fluid (which I dont want to just throw on the floor), also its 15 feet up in the air.
What I hope you will be able to tell me is method, like:
1 disconnect hydraulic couplings at the piston (plug pipe to digger unit.
2 connect manual hyraulic pump to expel fluid.
3 remove clevis pins...
etc. etc
how to bleed (if necesary)
remember this thing is big, heavy and not easy to get at.
