On The Edge Of Common Sense

The Dump Truck
Have you seen the movie, The Phoenix? A group of
adventurers crashed a big twin- engine airplane
in the Sahara Desert. Over a period of weeks they
rigged together a single engine plane out of the pieces
and flew off to a happy ending. That movie crossed my
mind as I shouted down to Mel, “Follow me, I’ll get it
rolling and coast to the truck stop!”
It all began Monday afternoon the day before. We
had hauled dirt for four hours until the F750 dump
truck that Mel had rebuilt and Elmo was driving, stalled
while trying to unload. Mel popped the hood and Elmo
climbed up beside him. Mel is a windmill man, well
driller, mule man, machinist and tinkerer of heavy
equipment. Elmo grew up in Mexico and can make anything
run if he has enough rebar and duct tape!
“A solenoid…” they deduced. “Maybe the wiring.
Rats, ya know. Wiggle the battery cable. Hand me that
7/8 wrench.” I did. He short-circuited the solenoid and
you could hear the starter whine. It was 4:45 p.m. when
I headed to town for a new solenoid and rebuilt starter.
We agreed to meet at 6 a.m. next day.
Tuesday morning with the new parts installed and the
handy 7/8 wrench they kept it running until noon when
it froze again at the dump spot…still loaded, of course.
They diagnosed bad ignition. Then checked the fuses
to find that the fuel pump was blown! Back to town
for parts. The truck ran for the next fifteen minutes,
allowing us to unload and giving us the false illusion
that we had it fixed. Enough so that we hooked up the
trailer and loaded the backhoe. Mel babied the dump
truck and made it a hundred yards, where it stalled
again. Diagnosis: out of fuel.
Back to my shop, return, pour in 2 gallons, put in
second fuse, short circuit the solenoid, and the parade
of truck, trailer, loader and two pilot cars made it to the
paved farm road, where it gasped and stopped again.
Fuse blown, plus Mel and Elmo concluded it was the
wiring on the fuel pump…rats, again. I go back to the
shop to bring electrical wire and black tape.
When I returned to what now looked like a roadside
attraction, they had concluded it was the fuel pump
itself. Plan: to circumvent the fuel pump altogether!
Mel and I arrived at the Auto Parts just before it closed
at 6 p.m. He built a detour fuel line that began with a
brass nipple that screwed into the carburetor inlet, followed
9 feet of rubber gas line and ended taped to the
spout of a two-gallon gas can.
Back at the scene of the crime, Elmo is waiting for
us. The two-gallon can is suspended from high up on
the side mirror with baling wire and the rubber gas
line wending itself under the hood, around the moving
parts and carrying gas by gravity into the carb. Voilá.
Third fuse replacement, 7/8 wrench, and we are on our
way. In the next mile it stalled twice more but at 7:30
p.m. I coasted the brave little dump truck the last 500
yards into the Truck Stop parking lot. As we swung
off the four-lane highway in single file, hood not quite
latched, and a gas can hanging off the right rear view
mirror I thought of The Phoenix. And of Tom Joad and
the Grapes of Wrath. I concluded that if I had to drive
from Oklahoma to California during the Dust Bowl
depression days in a beat-up Model A with four kids
and a mattress on the top, the two guys I’d want with
me would be Mel and Elmo. God bless ‘em. |
