T
he two side personnel access doors on your M88A1 recovery
vehicle are heavy and hard to open. But they won’t get any
easier to open if you don’t lube the hinges on a regular basis.
Lube the hinges quarterly with GAA like it says on Page
J-8 of TM 9-2350-256-20. Swing the doors open and
closed to help spread the lube. That’ll make the doors a lot
easier to open next time.

•
Generator toggle switch.
Flipping the GENERATOR toggle switch back and
forth while the engine is above idle speed can trip the breaker. There’s no need to
use the toggle switch at all since the Hercules has the 650-amp oil-cooled genera-
tor. The switch should
always
stay in the down position.
T
ripping the circuit breaker on top of the voltage regulator of your Hercules can be
a real pain. The metal splash shield, NSN 5340-01-421-2084, that covers the circuit
breaker has to be removed before you can reset the breaker.
Your best bet is to keep from tripping the circuit breaker in the first place. Here
are the main causes:
oww!
Lube

Don’t flip GENERATOR

•
Poor battery condition.
Dirty or corroded bat-
teries can trip the circuit breaker. Keep ‘em clean.
•
Loose generator connections.
Loose or cor-
roded generator connections can trip the circuit
breaker. Keep connections tight and clean.
•
Corroded voltage regulator.
Corrosion on the
voltage regulator itself can lead to a tripped
breaker. Keeping it clean is your best defense.
A new kit is being fielded to replace the metal
splash guard with a flexible rubber guard. Once
installed, the rubber guard is easily lifted up so
you can reset the circuit breaker. The new guard
will be provided by TACOM’s Recovery Vehicle
Management Office as part of a contractor-
applied modification.
