•
Remove tires from the manufacturer’s
wrapping as soon as you can after they get
to the motor pool. That way they loosen up
a little before you work with them.
•
Tires that sit in cold weather should come
indoors at least 24 hours before they’re
mounted. Cold weather contracts and
stiffens rubber.
•
Store tires on their treads. That widens
the gap between the beads and makes
mounting easier.
Dear Editor,
You ran a great article on using the Hawker battery in PS 664 (Mar
08). But there are three points you might want to clarify:
1.
There is ONE exception to the prohibition on “mixing Hawker and other
battery types on the same vehicle” mentioned on the top of page 11. There
isn’t a Hawker battery for the Bradley turret!
Because the systems are electrically separated, you may safely use four
Hawkers under the driver’s seat, while using the standard pair of “little”
batteries in the turret. I am unaware of any other safe exceptions to the
“all or none” rule.
2.
If you are replacing 6TMFs with Hawkers because of battery problems,
make sure the problem is not elsewhere in the electrical system. Hawkers will
not fix bad wiring.
And if only one battery of a set is bad, make sure the batteries with
remaining life go back to your battery shop to be mated with batteries of
similar characteristics for non-critical applications.
3.
TB 9-6140-252-13 is THE Hawker technical information source. If
there is a conflict between the TB and TM 9-6140-200-14 related to the
Hawker battery, the TB guidance is what you should follow.
