BOMB! (Hydraulic Pressure Accumulator)
The hydraulic pressure accumulator holds pressure in the system for
emergency assist if the hydraulic pump fails or the engine quits
altogether. It's a nitrogen vessel that holds several thousand PSI. It
is believed that over time the nitrogen leaks out of the system
(diffused through the diaphragm), because almost all accumulators start
to go bad after about seven years of service. The unit has been given
the nickname of "bomb" because of the shape of older versions -- rather
like a cartoon bomb seen on the Rocky and Bullwinkle Show.
