Default 1918 Wisconsin T Head

Picked these up this weekend. Not sure what to do with them. I was told they are surplus 1918 army truck engines. They been sitting in a barn for a long time. Wish I knew some one who might need one.

There is a fellow on here who goes by Tharper. He is rebuilding one of these for a Lombard log hauler. He may be interested.

As mentioned above, Terry Harper has been extensively rebuilding a Wisc "P", posting progress here and, extensively, on modern machinist (or is it practical machinist?---Googling Terry Harper Wisconsin should bring it up)... by now he probably feels one is more than enough, but has no doubt been contacted by others looking for engines or parts...do contact him, he's always friendly and helpful, and loves to talk old Wisconsins...
While could be military, they're not the Class B, which're generally listed as Cont'l B2 and sometimes B5, a side valve 43/4x6...
If there's any ID on them, and Terry doesn't have leads, I can see if there're any familiar names with clubs to contact.....

Nice find!

They are Wisconsin Model "A"'s (4-3/4"x5-1/2") They were used in WW1 era FWD trucks as well as Stutz and a few other automobiles of the time.
I would be curious to know if there were any loose parts laying around - water pumps, flywheels, oil pumps, etc. The water and oil pump are the toughest things to find.

Very nice! I have sent the word out to a couple of contacts! I would love to have one but.... my dear wife has told me I have enough on my plate!

Best regards,

Terry

Hi Vernon,
Nice find. I would use engine ads, hemmings motor news, and hmvf as they are regularly restoring slight shadows from WW1 trucks into the real thing!
Nathan.

I did see different oil pumps laying around, but I didn't know at the time these engine had an external pump. Now the property has been sold, so I can't go back and look. I did get some exhaust and intake manifolds, one water pump, and 10 magnetos, (I think they go to these).

Nice Vernon!

The water pump is a bear to find so that's good!

Best regards,

As also mentioned above, your Military possibility was correct after all---found an old note that the "A" powered FWD, built for Military in WWI, was made the standard vehicle of the Army Ordnance Dept....
Apparently their first engine, first production had to be circa 1910; notes (undoubtedly from some website) said very successful engine, gaining considerable popularity per exceptional performance...would be interesting to know if engine still in production or resurrected for the WWI military contract...
Sounds like your only problem will be deciding which offer/s to accept..
Nice save...
New owner of property may appreciate offer to clean up any remaining junk???

It truly is a treat to see those. There was a time I would have loved to jump into a project like that. I hope you find the right people to have them.
Thanks

I am building two early race cars with this engine. One of my cars is missing the oil pan and oil pump. I would be interested in at least one of these, maybe all four. I sent you an email.

Here are some figures and info from the scant Wisconsin literature I have:

The Model "A" was indeed a popular motor. As mentioned before FWD, Stutz and a host of other makes - what became known as "assembled" automobiles. The Marine version was called the "AM" and was a highly regarded motor. The major difference being the exhaust manifold and setup for a marine reverse gear running off what would otherwise be the front of the engine.

The 'A' used a pressurized oil system. Which in a era when many T-heads were splash only was high tech. Today we expect oil pressures of 30 to 40 psi but here we are talking high volume at low pressure (5 psi @ 1,000 rpm warmed up) The oil pump is external and driven off the camshaft by a vertical shaft. The type 'A' holds 7 quarts (my big "PT" takes 20!).

The 'A' shared the same bore and stroke and cylinder blocks as the "G" which was a six cylinder variant (I have yet to come across one of these!) Peak horse power was a little over 60 hp at 1,600 rpm (I am taking this off a graph)

The cylinders are fine grain grey iron with the cylinders and valves surrounded by generous water passages. The cylinder are bored, reamed and ground.

The crankshaft was balanced on a Norton Balance machine and connecting rods and pistons weighed and matched. Pistons are slightly tapered and the cylinders are offset slightly from the centerline of the crank.

Bearings are bronze backed babbitt that were hand scraped to fit.

After assembly each engine was run-in on a belt than run under its own power at an idle for "5 or 6 hours" than hitched up to a brake and run under full load for "at least 10 hours". They were then partially disassembled and inspected, the compression checked if all was "ok" crated and shipped.

Like many manufactures of the era these engine were assembled by a "fitter" who would carefully assemble an engine in its entirety before moving onto the next - carefully filing or lapping parts as required to get the best fit.

They don't make them like they use to!

That engine series seems to be A---AI---the AM mentioned above---and AU, per a 1930 McCord catalog showing the four, all 43/4x51/2, lumped together for gaskets...
A 38 Victor catalog also shows a couple apparently different engines:
AS 4cyl 5x61/2, an en bloc (one illus head gasket)...
A5 4cyl no b/s shown, no head gasket illus (unusual) but lumped in with B52 and B53, which don't appear elsewhere...but there are B2 4cyl 51/4x61/2 and B3 4cyl 51/2x61/2...
OOPs...a 30 wrist pin catalog shows an AG with the AU, the 43/4 bore...
Sounds like they had a version for everyone......

Hang on the Stutz restorers are going to beat a path to your door!
Another possibility is all of the FWD's out there minus an engine because it was taken out for a Stutz.
