This the front and rear of my HUP, pictures where taken
July of 2000. General condition of vehicle at this point was all exterior
parts were original. The following parts are not original:
Bridge Plate
Shovel and Pick Axe and their attachments
Radio Aerial is not correct for CMP HUP

Note the mirrors ones shown at left are
US M151 mirrors while the round mirrors below are sandard commericial
truck. The correct mirrors are retangular and smaller than the M151 mirrors. |
In this shot the rear hatch and sliding rails have been removed.
|
These photos were taken summer
2002 when I started to straighten out the roof which from years of use
being used as a platform had taken on a swayback shape. This along with
leaks and broken spot welds finally required serious work. |
The stake across the roof gives you and idea of how much roof has
been bowed in from people standing on it.

Detail of the spring loaded hatch rollers this is what lifts the
hatch up so that it can slide.

Detail of the rear sliding hatch.

This picture was taken in 1978 just after I got the HUP home gives
you and idea of the conditions as this was the worst of the damage.

being restored |

|
Note that the link arm has broken the weld at the lower
ball end. This occured once before on one of the front links years ago
and was repaired in that case by removing and welding the parts.
|
Note the lower ball end the weld around the link has just failed.

Left Rear Shock Link as there is no provision for lubricating these links
wear is evident from some 64 years of use.

| Over the years I have seen various Spare Parts List Books
for the HUP with different dates the one that came with my HUP is dated
June 1945 and shows a number of running part number changes. Back when I
was first collecting information about HUPs I was corresponding with Bart
Vanderveen and he had not see a parts list dated that late, I sent him a
copy of mine. Comparing when parts changes showed in the parts book was
one of Bart's ways of dating particular vehicles as in many cases the a
parts change will show a notation "before Serial No 484-16967" |

Routing of the front brake lines on HUPs is different from many of the
earlier CMPs. With a single rubber flex hose coming down from the chassis
to a distribution tube on the back side of the axle housing. Then to rubber
flex hoses at each knuckle to the brake cylinders. The other Chevy CMPs
had individual flex brake lines going directly from chassis to the brake
cylinders these had springs on them to hold them away from the wheel when
steering was turned hard over to one side or the other. As the service
bulletin below states this routing out in the open under the fenders was
subject to damage particularly from tire chains so the behind the axle
routing was a service modification. I suspect that this change was made
also to speed repairs because the routing of the steel brake line on the
other Chevy CMPs would be difficult to repair in the field as it runs
under the radiator and through the frame rails.
These two pages are excerpted from the Service Information Bulletins
????????????)
this is very interesting summary of changes made to correct problems in
the field. In it you will find explanations for why things are not as
they are shown in the manuals. I have found server modifications that
I had assumed were made after my CMPs had left military service because
they are not shown in the normal CMP manuals, which in fact probably were
done while the truck was in active service.
Interesting feature of Chevy Stove Bolt Six that can be seen in all of
these picture. The self undercoating and rust prevention system. It would
seem that left to themselves vehicles equipped with these engine will
cover the underside of the truck in oil.

The intervening pages give a detail parts list for making this modification
on different trucks.
