C) Disassemble and replace spring(s).
Long pump-up time
A) Pre-charge too low or no pre-charge pressure.

B) Low pump volume

C) Weak spring(s)
A) Check pre-charge pressure and recharge as necessary.

Accumulator fails to absorb shock pressures
A) Pre-charge is lost

B) Pre-charge is too high

C) Diaphragm or bladder ruptured
A) Check pre-charge pressure, recharge as necessary.

B) Same as above

C) Check operating fluid temperature, reduce if too high. Bladder pinched when installed; replace following manufacturer's installation procedure carefully.
