MY SHARE OF THE LOAD
P O Box 358, Clifton, Colorado 81520
After reading GEM for the past few years, I realized it is my
obligation to submit something as my share of the load to keep
things going. I enjoy reading about others’ experiences, so I
need to add my own. I was raised on a ranch where the small
gasoline engine was a common and necessary piece of the scene. I
have always had an interest in the old, slow speed, one-lungers and
felt I was probably the only one on the planet who appreciated
their contribution to history. I salvaged what I could when my dad
retired and sold the homestead, thinking I would restore my
‘treasures’ just to satisfy my own interest. A few years
back, I got on the Internet, just poking around, and started
looking for antique iron-tractors, equipment, etc. What I found
amazed me! There were actually people out there who had the same
interest in the old ‘snort and wheezers’ that I did.
Fortunately, about this time, I was able to retire and devote the
time and energy to rebuilding the rusty iron I had packed back and
forth every time we moved.
My first project was an old and dear friend who was not actually
a member of the family until fairly late. I bought an International
Harvester LA out of the junk pile in the late ’50s or early
’60s, probably ten bucks, to use to water the yard instead of
having to run power for an electric pump. This engine was belted to
an old Fairbanks-Morse centrifugal pump from a dairy can washer and
first pumped out of a shallow well and then out of an open ditch,
until the ditch was put into buried pipe with enough head to
gravity water the lawn and garden. Needless to say, my wife was not
sad to see the old engine retired, as the two of them didn’t
speak the same language, but I enjoyed hearing the
‘putt-putt’ when it was running. Retirement came in the
late 70s and the old LA waited until 1998-1999 to get a place in
the sun again.
I thought restoring this engine would be fairly easy, as it was
fully enclosed and had always been under cover, at least as long as
I had it. No frozen pistons, broken parts. Most of what was not on
the engine was in the box of ‘small engine parts.’ I had
taken the mixing valve off and added a float style carburetor and
air cleaner. The gas tank had been discarded and replaced with an
elevated gas tank. I had also added a crankshaft power shaft to get
around the 2:1 reduction in the output shaft. This gave me speed
enough to drive a centrifugal pump.
First thing was to clean up and check everything over and find
out what didn’t work. Years of use with no cleanup had added
their layers of dirt and grime. After a scraping and washing,
installing the original mixing valve, making a temporary gas tank,
an oil change, and we could give it a try. Somewhat reluctant, but
it started-kind of. The spark was weak when cranking and didn’t
appear to improve after starting. Compression was so-so, but no
major problems mechanically.
The magneto appeared to be the major problem. The impulse
worked, but the mag didn’t fire every time and had a weak
spark. The coil checked okay, but no way to test the magnets. I
decided we needed a magnet recharge. There used to be at least one
good magneto shop here locally, but they shut down several years
ago, sold off what they could and stored the rest-no help there.
Calls to the local old iron people offered suggestions, which I
tried, but no one wanted to work on a Wico H, no parts available.
What it boiled down to was, fix it myself.
First thing I had to do was build a magnet charger. Lots of
plans out there to build a charger, but there must be an easier way
than winding coils. GEM had an article about using starter
solenoids from large engine starters, which proved to be a good
solution, with some modifications to make it more versatile. A
magnet recharge improved the quality of the spark, but still not
consistent. Nothing would show the condenser to be faulty, but all
indications were in that direction. The installation of the
condenser in the case doesn’t leave a lot of options. A new
condenser from an electronic shop didn’t help. But lo and
behold! I found a repair kit for a Farmall ignition system in, of
all places, the local discount store, with a condenser of the right
capacitance and size and shape to fit the magneto case. Suddenly
(almost) we were in business. Put it all together, a new gas tank
from Lee Pedersen, minor adjustments to the mixing valve and away
Now we had to strip everything down, clean, scrape, wire brush,
and don’t forget the oven cleaner. Works great on grease and
old paint. Fill in the miscellaneous holes from past mounting
bolts. Make a valve cover from an electric motor end bell cover.
Make a cover for the water hopper-never had either of these parts.
Remove the head and grind the valves and seats. Of course we had to
make a valve seat grinder first, because nothing we had would go
that small. Oh well, probably will need it down the road anyway.
Remember that a die grinder on your lathe tool post will do a great
job on occasional valve grind jobs. Just make sure to cover the
Opened the crankcase for a look. The crank bearing had
(surprise!) excess clearance. The main bearings felt pretty good. A
piece of Alcoa wrap behind the crank insert took care of the
problem. Rings and piston were good enough for a long while yet.
Put everything back together-head gasket leaked. Made a new head
gasket out of Garlock 3200. Works well on low load applications and
available as scrap from someone who cuts pipe flange gaskets.
Everything got a coat of rust converter and then metal primer. A
nice finish coat of grey and red for the engine, and black on the
base. Probably not what came from the factory, but this old girl
deserved some fancy clothes. I have handled this engine too many
times the hard way. Now is the time to put wheels under it. Cut off
pieces of 8′ pipe, ?’ pipe for hubs and 1? strap for spokes
made the wheels. Other scrap plus common 2×4’s completed the
base. Some varnish, paint, and the router finished it up. One
mistake, I figured I could live with not having front wheels pass
under the cart. WRONG! I have since had to notch the cart rails for
the front wheels, which means I will have to go back and re-do the
rails at some time. At least we were up and running in time for our
first display last fall.
This winter, I have been rebuilding a yard pump jack to go along
with this engine. I had to do more work on this project than on the
engine itself. Rebuild gears, repour babbitt bearings, machine new
shafts, restore the pump body and manufacture a pump. Actually, the
more shop work there is, the better I like it. Great place to play
and keeps me out of the bars.
A few other thoughts I like and will pass along:
Duco cement or clear nail polish makes a good light duty thread
locker (machine screws).
Celotex sheathing (the black stuff) makes a good fatigue mat on
My favorite penetrating oil is ? n’ ? #2 diesel and Marvel
Mystry oil. I’ve seen it do amazing things and it is cheap.
Don’t forget a liberal dose of patience along with it. Also
good as brass and aluminum cutting oil.
Roofing felt makes good low pressure/temperature gasket
material. Makes large gaskets easy. Not too good on oil or
petroleum products. Also good for patterns.
A great shop magnet is a ‘cow magnet’-fed to cows to
pick up tramp metal in their stomach. Cheap at a slaughter house.
Buy new at a livestock supply.
Need a light duty expanding mandrel? Use your expansion reamers,
take light cuts. Every shop should have a set, as cheap as they are
I have two more carcasses awaiting resurrection. One partly
rebuilt and one undergoing the ‘anoint and wait’ process.
These will be more of a true restoration from the dead and will be
another story. If anyone wants to contact me about specifics or
