This 4 HP Holland Vertical engine is owned by Carl Lohman. Read all about the restoration of his engine

Fascinated by steam and gas engines since childhood, I have
attended as many shows as possible, dreaming of the day I would
have an engine of my own. Two years ago those dreams became reality
and grew to be an obsession when I got my first engine, a 4 HP
Holland Vertical. This type of engine is seldom seen, so I will try
to pass on as much information about it as I possibly can.

When I acquired the engine it was still belted to a force pump
and lag bolted to a rotten-but still massive!-oak plank. Loading
this unit into the truck in one piece was accomplished by lifting
the pump end onto the tailgate, then sliding the whole thing into
the bed using the muscle-power of four people. When I got home it
became obvious that to get the engine in the workshop it would have
to be removed from the plank and strapped to a dolly. Even with the
help of a sturdy dolly, the friend helping me and I were amazed at
how top-heavy the engine was to move. However, with care and great
effort we got it safely into the shop.

In my spare time I used a needle sealer to clean all the cast
iron parts. I found this sealer restored the iron’s appearance
and removed most of the pitting. After the dirt and grease were
cleared away, the engine was disassembled to check the parts for
wear. It became obvious that the Holland Engine Company (of
Holland, Michigan) purchased many of their parts from the Ford
Motor Company. The piston, rings, and connecting rod were all
marked Ford, and turned out to be Model T parts. After making many
inquiries I learned the valves, valve springs, spring retainers,
solid tappets, manifold glands, gland rings, and Holley Model N H
carburetor were also Model T Ford engine parts. None of the parts
showed any signs of excessive wear. Even the cylinder bore measured
straight and concentric within +0.0002′ -0.0000′, a
tolerance that is evidence of skilled machinists and design
foresight we seldom see today!

The original steel fuel tank was not salvageable, so it was
replaced with a copper tank that I hand made to the exact size and
shape of the original. There were leaks in the radiator that I
repaired, and the magneto was missing so I had to locate a magneto
that would fit. A new 3/8‘ round leather
belt was located to drive the fan.

The engine was given several coats of paint, matching the
original color with True-Test Nile Green XO-19, IBM No. 378

Speed on the engine is adjusted with a thumb screw and wing nut
at the end of the governor shaft, and movement of the governor arm
throtles the carburetor to maintain constant speed, so it took only
some minor tinkering to have the engine operating smoothly and
ready for the local shows.

Since most of the summer was gone, I was only able to exhibit my
engine at the Tri-State Historical Steam Engine Show, the Hickory
Apple Festival, and at the Northwestern Steam Engine and Old
Equipment Fall Fling Show. My only problem now is how many engines
can my wife Diane and I take to an engine show with only one pickup
and a trailer?
