    Dealing with what I believe is a Cat H55D S breaker. I've got the nitrogen charge spec for the bladder accumulator (the one on the side that you access through the rubber plug in the side). Part breakdown seems to indicate another accumulator at the back end, behind the piston (where the hoses connect). Is this actually a serviceable accumulator? How is it charged and what is its spec?

    I believe the S/N prefix is FTF.

    Doesn't seem to be another accumulator according to the SysOp.

    What Nige is saying is that the systems operation manual for this model breaker only mentions that one accumulator is fitted
