Changing a NACOL "Top Loading" Accumulator is as easy as 1-2-3.
1. Remove Top 2. Take out bladder 3. Replace bladder
In case the bladder ever does fail, the "Top Loading" feature makes bladder replacement very easy. By removing the top cover of the accumulator, you have access to the accumulator. There is no need to remove the accumulator from the hydraulic piping in order to replace a bladder

This illustration shows the compressed pleated bladder for the NACOL accumulator. The bladder compresses star shaped, never worn by the friction of rubbing against the shell. The bladder lasts longer, therefore
the accumulator lasts longer.
