Figure 1
: Once the accumulator has been removed
from the equipment, the accumulator body should be
secured in a vise, preferably a chain vise. If a standard
jaw vise is used, brass inserts should be used to protect
the accumulator hydraulic port assembly (Item 7) from
damage. Clamp on wrench flats only when using a jaw
vise to prevent accumulator from turning.
Figure 2
: Remove bleeder plug (Item 21), if the
accumulator is equipped with one, on hydraulic
port assembly.
Figure 3
: Using a spanner wrench, 0851100000,
remove lock ring (Item 8) from the hydraulic port
assembly (Item 7); use an adjustable wrench on the flats
located on the port assembly to prevent port assembly
from rotating. Remove spacer (Item 10), then push the
hydraulic port assembly (Item 7) into the shell (Item 1)
prior to Step 4.
Figure 4
: Insert hand into the accumulator shell
(Item 1) and remove the O-ring backup (Item 16),
o-ring (Item 14), and metal backup (Item 18). Separate
the anti-extrusion ring (Item 12) from the hydraulic port
(Item 7). Fold anti-extrusion ring to enable removal of
anti-extrusion ring from shell.
