JD 4440 brake accumulator

Pet The brake accumulator of our 4440 is leaking hydraulic oil. JD dealer suggested that replacement with a new accumulator is the only option.
Accumulators are over a $1000 CAN. Can they be rebuilt? Somebody know a place to get used ones?

Hoss They can be rebuilt much cheaper if the barrel or other parts are not damaged. These can be dangerous if they are not discharged properly before dissassembly. Otherwise it is not that hard to rebuild, it's harder to get out than to rebuild. It does take special equipment to recharge with dry nitrogen after the rebuild. The dealer may not have this equipment as to why they cannot rebuild it.
Hoss Now that I think of it, it cant be rebuilt.. SORRY
Hoss Looks like somebody wants to play games. That last post wasn't by me. It can be rebuilt.
