Assembly & Disassembly
Bladder Assembly in Conventional
Top-Repairable Accumulators
1
Spray the inside of the accumulator shell (Item 1)
with a liberal amount of clean system hydraulic fluid
to lubricate and cushion the bladder. Make sure the
entire inside of the shell is lubricated.
2
With all gas completely exhausted from bladder,
collapse bladder (Item 2) and fold longitudinally in a
compact roll.
3
Install the gas end adapter (Item 23) on the bladder
and secure with hex jam nut (Item 5). Torque hex jam
nut to 100-120 ft-lb (136-163 N-m).
4
Insert bladder/adapter assembly into
accumulator shell.
5
Fold anti-extrusion ring (Item 12) and place
inside accumulator.
6
Reaching inside the accumulator, insert the gas end
adapter (Item 23) through the anti-extrusion ring
(Item 12) and pull into place. The steel surface on
anti-extrusion ring should face outward.
7
Holding the gas end adapter (Item 23) in place, fill
accumulator with approximately 50 PSI nitrogen.
This will hold the gas end adapter in place.
8
Install the metal backup (Item 18), o-ring (Item 14),
and o-ring backup (Item 16).
9
Install the outer spacer (Item 10).
10
Install the outer locking ring (Item 8).
Hydraulic Port Assembly Installation
1
Holding the hydraulic port assembly (Item 7) by
the threaded end, insert the poppet end into the
shell fluid port. Lay complete assembly inside
shell (Item 1).
2
Figure 14
: Fold anti-extrusion ring (Item 12)
to enable insertion into the shell. Once the
anti-extrusion ring has cleared the hydraulic
fluid port opening, place the anti-extrusion ring
on the hydraulic port assembly (Item 7) with the
port assembly’s steel collar end facing toward
the shell fluid port.
3
Pull the threaded end of the port assembly (Item
7) through the shell fluid port until it sits solidly into
position on the shell’s fluid port opening.
4
Figure 15
: With port assembly firmly in place,
install valve core (Item 3) or gas valve (Item 26) into
the bladder stem (Item 2). Slowly pressurize the
bladder, using dry nitrogen with sufficient pressure
(approximately 40-50 PSI) to hold hydraulic port
assembly (Item 7) in place so both hands are free to
continue with assembly.
