Dear Editor,
Reconnecting broken track or installing new track on your Bradley can be
a real pain. Even when using the track connector, we still sometimes have
problems lining up the bushing holes just right so that the connecting pin will
slide in.
A lot of guys try to bang home the pin with a sledgehammer. That may
work in the short run, but it causes damage to the pin and bushings that will
eventually result in track failure.
We’ve found
that you can use a
tanker’s bar to help
with the connection.
Just wedge the end
of the bar between
the two shoes and
pull up and down
to manipulate the
bushings until they
line up. Then the pin
slides in easily.

A roadwheel relief valve that’s clogged with dirt and sand won’t relieve pressure
when you pump in new grease. The pressure grows until something gives—usually
the hub seal.
When the seal goes, so does
the lube. The result is burned-out
bearings.
So before adding new grease,
use a cloth to wipe away any dirt
and sand from the relief valve.
Then pull out the valve plunger.
If it slides out smoothly and
pops back in when you release
it, the valve’s OK. If it doesn’t,
replace it with relief valve, NSN
Editor’s note:
A simple solution to
a tough problem! Good work!

so you think you

well, the roadwheels

I don’t

no matter how

that’s
