‘Second Chance’ 7 HP Witte Runs Again!

Some GEM subscribers remember the story I submitted in the June
1998 issue about pulling the main part of a 1923 7 HP Witte engine
out of Flathead Lake. It was in thirty feet of water and had been
used as a buoy anchor for forty years. Fortunately, for some
unknown reason, the flywheels, crank, rod and piston assembly, gas
tank and oiler had been stored in the boat house. Some of you may
have wondered if I ever got it going.

Cylinder bore and babbitt bearings cleaned up pretty well after
some forty years in Flathead Lake.

Who would have thought that after forty some years in the lake,
the Witte mag and carburetor would ever function again?

I set the goal of having it running this year for the Miracle of
America’s annual Live History Days, the third weekend in July.
Remember I had steam cleaned it after pulling it out of the lake
and 90% of the parts moved. I should have gotten to it right away,
or at least sprayed it down with light oil, because its surface
rusted pretty badly in places.

With the encouragement and help of friends, Ed and Sue
Brueckman, who have recently become addicted to old iron and
flywheels, it finally started. The engine cleaned up well. I had to
braze a broken ear on the mag mount. Ed JB welded a broken corner
on the needle valve boss on the carburetor. Fortunately I had a
newer ‘parts’ engine which had the carb and filler cover,
valve springs and retainer, which had rusted beyond use on the
original engine. Ed just touched up the valves and seats. We sent
the magneto to WJW in Maida, North Dakota/Morden, Manitoba, Canada.
He had read of my previous story and was anxious to help get the
Witte going. He provided quick service and it worked perfectly.

I had a frame and rear wheels from an old cement mixer and a
nice front axle with matching wheels of a smaller size (although
they were still too big to turn under the frame). This problem was
solved by building an arch assembly using ‘ x 6′ x 6’
angle iron and 3/8‘ x 6’ flat. I
machined a sleeve so a clutch could be installed and mounted a 4
‘jaw crusher on the cart as well as a steel box to hold two
five gallon buckets of rock to crush.

While we did get it running and crushing rock for our Live
History Days, we had a few bugs to work out with the magneto trip
rod. The cam gear pin was pretty badly rusted and it took more than
an hour to four-jaw it up just right, but I now have a perfect
finish on it. We built a new rod and end, and bushed it to fit the
new pin size. Ironically, it turns out the bore of the cam gear and
bolt/pin were not rusted or worn. I’ve thought that perhaps
some parts had more grease or oil on them, but normally a valve
stem doesn’t retain that much oil. So why were they in good
shape and the springs rusted beyond use? Oh well, I have more
important things to wonder about, like why does it start sometimes
on the first pull and other times it takes five minutes? The
exciting thing though is, IT RUNS! But, don’t think anyone will
be hiring me to crush rock.

I have dubbed it ‘Second Chance.’ We did a quick brush
paint job and showed it at the Northwest Power Association annual
fall show in Columbia Falls, Montana. We also showed a 1 HP Handy
Andy Galloway and a Vaughn Flex-Tred garden tractor.

I sure enjoy your magazines and appreciate the articles
you’d done on the museum artifacts. Thanks.
