The
Restoration Chronicles of 721
by Jerred Ruble
I
purchased this engine at Leonard Rynda’s sale in May
of2004. The engine’s number is 721, built in 1893. I have been told by a
reliable source this is the oldest know Minneapolis engine left, but I have no
way to verify this other than someone telling me my claim is incorrect, which I
encourage anyone to do.
I
received a lead about an engine # 512 thought to still exist. The engine showed
up on the steam-tractors web site.
After making several calls and one trip I discovered that all that remains of
#512 is the cylinder with its name plate. I consider this as a remnant and no
contest for my claim that #721 is the oldest surviving
Here
is a picture of the engine (copied from the steam traction site) as it sat for
over 50 years at
I
will attempt to provide a chronicle of the restoration on this page, updating
the page as the restoration process continues. The work is being done at Heritage Park of North Iowa.
This year’s mild winter has allowed the work to proceed in the large unheated
machinery building. You will notice partial pictures of other units stored in
the building.

The goal today was to remove all the piping from
the engine. I only had about three hours to work on the project. I first took
pictures of how all the existing piping was plumbed so I can use it as a
pattern when I get to the piping point later in the summer. I know it was not
the original pipe, but from factory photos I was pretty confident it was
plumbed the way it came from the factory. Click on Picture for

|||||||
As
I removed the pipe, I put all the fittings back together to use as a pattern
when I installed the new pipe. I was a little surprised to find that a mouse
had found his way to the cross head pump. Click on Picture for

A
problem presented itself as I went to remove the bottom valve for the water
column. To remove the valve I discovered I will first need to remove the gear
guard. That project will need to be left for another day. My three hours was
just about up. Other than that problem though, I did manage to remove all of
the other piping. As you can see, it required a little heat to remove some of
the fittings. Click on Picture for

Over the Holidays, I made the decision to essentially have a
new boiler constructed. Craig’s Restoration Services from |

January 7, 2006 |
The goal today was to remove the engine. I wanted to remove
the engine intact if possible. This would greatly simplify the reassemble
project. Removing the engine would consist of removing 36, ľ” cap screws that
held the engine mounting castings to the boiler. I am sure they had not been
removed since installation at the factory in 1893. Most of them were rusted
in pretty good. We had to use some pretty heavy duty brut force to get them
out. We broke only 4 of the cap screws. The rest of them came out but we
ruined the threads in about 90% of them. I’ll need to get all new ones mode.
I had several friends stop by to help out. My thanks to Click on Picture for

Brian and Eric were over this weekend to help
out on the 15 Rumely restoration. We
completed what we wanted to accomplish on that project on Saturday, so we
decided to work some on 721. Didn’t have a lot of time so we decided to
polish some brass. Eric took on that project. As you can see he has most of
the brass look’n good. Click on Picture for

The new boiler arrived.
My IH 806 had a hard time lifting the boiler, but we managed to get it off loaded
and safely on the ground. That’s Craig Dobbins and yours truly breathing a
sigh of relief. |
|||||||
|
|
|||||||
After over of year of
down time, my helpers and I started mounting the fixtures on the new boiler.
The boiler is sitting upside down allowing easier mounting of the rear axle
assembly and front pedestal. That’s Brain Paterson helping out on this day. |
||||||||

Collin Hall and Wyndham
Sellers showed up to lend a hand as well. Collin is removing the masking tape
from the intermediate gear fixture while Wyndham lends a hand to Brain
installing the differential shaft. |
||||||||
|
|
|
||||||
With the axle assembly
installed, it was time to up right the boiler. This process required numerous
small turns with the crane until we had it right side up.. |
||||||||
|
|
|
||||||
Once upright we could
install the differential gears and the hind wheels. At the end of the day we
had the engine resting on its rear wheels again for the first time in 3
years. This was short of our 4 wheel goal, but Brian, Collin and I all felt
good with what we had accomplished in a single day. |

The fixtures were then
reposition and threads tapped with the fixtures in position to ensure each
cap screw would thread properly into the boiler. At the end of the day we had
the intermediate gear as well as the motor installed on the boiler. |

Progress to date. |
