I'll give it a shot. The reason for the power divider is to lock both
drive axles together when driving on slick roads. The interaxle
differential is locked out, enabling at least one wheel on each axle
to pull. If the differential is not locked out, the wheel on the hog
snot will spin, but the wheels on dry ground will just sit there doing
nothing. On dry pavement the lockout is not used or needed because
power is transferred to both axles equally anyway. Make sure the
wheels are not spinning when you use the interlock switch. Bad things
can and will happen to the gears, such as becoming busted, if the
lockout is engaged when only one wheel is turning. Also, spinning the
wheels without using the lockout can burn up the power divider
differential, especially on early versions. They didn't have the oil
pump to keep the gears greased. Oil pumps have been built into the
differentials for many years, so unless you drive a really old
vehicle, you probably won't have to worry about burnout. You can
disengage the lockout without stopping. Just move the switch and let
off the throttle for an instance. Don't drive real fast when using
the power divider, especially on slick roads. You can turn the
steering wheel, but with both axles locked together, the vehicle wants
to keep going straight.

What part of Kentucky are you from son?
Hog snot?...Anything like them "mountain oysters?"...sheesh...
The power divider should also be used when picking up a heavy trailer and
sliding tractor fifth wheel (hopefully you`ve lowered the landing gear) and/or
trailer tandems...
Imagine a part-time 4 wheel drive car. If imaginary car is in 2wd and
the drive axle is in mud, when you apply power, you will spin the wheels
and go nowhere. If you engage 4wd (lock out the power divider) and
apply power, the axle in mud will not be able to spin faster than the
axle with traction (it won't be able to rob the driving power). The
axle with traction will pull the car. But, in my experience the power
divider doesn't help when the wheels on both axles on the left or right
side are spinning.

Please clarify the "sheesh" and "lack of experience driver" comments.
I have driven pulpwood trucks in South Georgia. Without an operating
power divider, you're dead in the water. I also drove for many years
on the big road before going to the woods.

The fact is, most drivers have never been properly instructed on proper useage
of power dividers and the subsequent abuse that results...
Why do you think Mack went to a clutch system whereby it is brought into play
automatically before component damage results?

Thank you driver....we have one that was properly trained...a safety and
operations department that actually instructs the driver in correct component
useage before the driver drops a component and is subsequently fired for
equipment abuse...
There are training films available from component vendors...
Might be better reading than Super Trucker Magazine...

No...the concept came from the designers of the power divider...
But now with the availability of traction control combined with the ABS

To Bdsprd (bedspread?): I appreciate the reply. The way my news
reader (Free Agent) groups the threads, it's sometimes difficult to
match the reply messages with the posts I'm replying to.
Have you thought about those driver controlled locking differentials?
I don't know who makes them, Eaton or Rockwell, maybe both. All four
wheels on the drivers pull, not just one wheel on each axle as happens
with most power divider setups. They are for slow speeds only because
the truck doesn't want to turn easily when the locker is engaged. The
danged thing wants to keep going straight, but you already know about
that phenomenon, being a dumper driver.

Tony,
You evidently don't own any tandem drive Macks. Most Mack trucks use
an automatic power divider. The driver doesn't have any control over
the operation of it. Mack does make a driver controlled power
divider, but I believe all the switch does is enable the power divider
to stay engaged all the time. If you don't use the switch, the
automatic engagement comes into play when necessary. If one wheel
slips for whatever reason, hooking up, dropping, snow, etc., the other
wheels start pulling all by themselves. If the driver finds himself
in a situation where one wheel is off the ground, just tap the foot
brake, the power divider will engage and let the other wheels do the
pulling. Of course, with a regular power divider, Rockwell, Eaton
axles for instance, just flip the dash switch and drive off whatever
is holding the wheel off the ground. Stumps in the woods come to
mind. As the saying goes, been there, done that. Mack does use a lot
of double reduction differentials, so the torque load is spread over
several gears.
>I wonder BDSPRD....how long have you been driving? and where did you receive

Driver, I have been around heavy trucks since 1967, where I started with

I received my "training" early on with tandem dumps-65000lbs. gross where I

Instructional videos(useage and repair maintenance) can be sourced from

Can you find their site or do I have to hold your hand on this one too?

Don`t take dealer personnel word for anything...in most cases they have

Now, why is that? You can fuel, meal, and break all at the same time. You
can go off duty for all of it. As long as the company okays it. Now if you
are a company driver, they probably won't okay it. But if you drive by the

not to log fuel stops.

I disagree. As A driver and a service tech. If you engage the power
divider it cannot possibly give you more torque! The Torque comes from
the engine and not the drive train. If you engage te power divider it
distributes the torque equally between all four sets of wheels instead
of 1 or 2 sets, which if you think about it, it gives you less actual
torque to all sets of wheels than it would to 1 or 2 sets. The point is
you get even torque between all wheels. If you have all your torque sent
to 1 axle it will snap much easier than if you have the torque sent
equally to 4 axles.

These good folks are certainly going to be rudely discomforted by the
AFGO experience presented to them during their first DOT Audit. Bring

Oh, if you drive long enough, some nite you will be trying to hook up to
a trailer out in the far back, in the dark, off the gravel, waay back
part of some yard, snowing, raining, sleeting, (take your pick) ,
you might remember that little switch on the dash.

Wrong again! Many lease driver log what they do and do what they log, just as
manyt company drivers do. There are many companies trying to comply, and
competing with those who don't. Don't give me that no one does it routine, it
wont wash. We have been running legal logs for several years now, and have been
owner operating for 3 months. Still logging the same way. By the way If you
have a letter authorising it from your company you can log ROUTINE RTEST AND
BREAK STOPS off duty. The Letter must state that you vehicle if parked safely
is not your responsibility. This does not give you the right to log FUELING the
truck off duty unless you always fuel at FULL SERVICE fuel stops and are not
required to pay for the fuel, (say instead the fuel stop calls the company and
they P O the fuel directly.)
Trucking is the only profession I know where people who are expected to work 70
hours a week think they should LIE about how much work they are doing in order
to work more hours!

Well I couldn't find anything there to releive the driver of responsibility so
that they could log fueling as off duty. BUT I did find a link to the executive
secretariet so I sent the following e-mail to
margare...@fhwa.dot.gov
with the subject of
Request for official statment or information
Topic of interest:
It has been stated on the Misc.Transport.Trucking newsgroup on USENET that a
truck driver does not have to log time for fueling the truck.
Data:
As an interstate truck driver who is trying to comply with all the
regulations while still using my time wisely, I log all time spent fueling and
signing for or paying for Fuel as on duty not driving.
Several drivers have been posting that they never show fueling time. They
also further claim that they have a letter from their company stating that they
do not have to log this time as on duty not driving.
I have a letter from my company giving me release from responsibility for the
vehicle during routine rest and meal stops. But Our understanding is that
because the driver is involved in the fueling process they must log all time
spent fueling as on duty not driving.
Request:
Can someone give me any guidance on this. I read and reread the CFR on
drivers hours of service and cannot find anything that seems to specifically
address this in any way that would relieve the driver of the responsibility to
log this time on duty not driving.
Thank you
Rusty Wade
We'll see if I get an answer!
The use of the power divider that I stated came from a copy of the Owners manual
for one of the 1994 Kenworth 800's that I requested from my dealer here in
Chattanooga, Tn. The section was on the use of Eaton rears.
FYI.....been involved with trucking for more than 20years...in many
aspects.......refrigerated...dry...flat...logging....livestock....and even
"chickens" alive and dead. I've driven 'em, worked on 'em, and now I own 'em.
I don't profess to know it all...and I never will, but make no mistake, I'm no
"whippersnapper" either.
On one other note.....just because Schneider instructs a method to it's drivers,
it does'nt necessarily make it the correct one in all cases. It may be a policy
invoked by management for their own reasons, and/or experience. As I stated,
there may be some merit to the use of the power divider in cases where the driver
is not able to relieve all the weight off of the fifth wheel in order to adjust
it. 'nuff said....the truce is on.....

If one wheel of a loaded drive axle spins and then grabs traction, the chances of
breaking something expensiveis almost a sure bet. If you lock up both drive axles the
chances of a wheel spinning out is greatly reduced because you would have to spin
TWO wheels, one on EACH axle. This is less apt to happen which greatly reduces the
chance of breaking something expensive. If Schnieder is instructing their drivers to
lock up when hooking up I would suspect it is to keep their less seasoned drivers[ ie
the ones who haven't developed that mechanical sense that most of them get by
breaking lots of stuff] from gaining that knowledge at their expense. Another case in
