Cylinder Rod Protection
It’s not uncommon for rollers to sit in the motor pool for long periods between
operations. So the roller’s hydraulic lift-cylinder rod is constantly exposed to all
kinds of weather.
That means the rod can become
corroded and pitted. In fact, the pitting
can become bad enough that the rod’s
seal can’t prevent Fuid leaks. Once
the leak gets to Class III, your roller
becomes NMC.
Stop
corrosion
in
its
tracks
by
exercising the cylinder once a week.
That keeps a thin coat of hydraulic
oil on the cylinder rod. If you can’t
exercise the roller, protect the cylinder
rod with a thin coat of GAA.
Battery Disconnect Switch
The batteries on your self-propelled vibratory rollers can run down if you don’t put
a stop to it.
So after the day’s run, make sure you turn off the battery disconnect switch. It’s
located behind the passenger side engine access door. If you leave it on, the batteries
will lose their charge within three to ±ve days! No juice means your roller needs a
slave start or it won’t be going anywhere!
So, if you detect water seepage
around the access panel, open the
panel and let it dry out. Have your
mechanic dab some RTV sealant
around the top edge of the panel next
to the housing. That will help keep
moisture out. It’s also a good idea to
make sure the panel’s turn knobs are
tight so moisture can’t seep in.
Dear Half-Mast,
The article on the standard
automotive tool set (SATS) on
Pages 40-42 in PS 722 (Jan
13) implied that under normal
conditions it would be OK to tow
SATS with an LMTV.
But the LMTV towing capacity
is rated at 12,000 pounds. The
SATS combined with its trailer is
close to 16,000 pounds, which
to us means the SATS should
never be towed with an LMTV.
Is this correct?
CW2 M.L.
Dear Chief M.L.,
Yes. TACOM recommends you tow
SATS with the M1083A1 5-ton truck. It
has a towing capacity of 21,000 pounds,
plus an extra axle, which gives more
braking power than the LMTV, and a
larger engine than the LMTV. That makes
for a safer trip. If an M1083A1 isn’t
available, use a truck that can safely tow
at least 20,000 pounds and has a pintle
capacity of 2,100 pounds.

right
truck!
