Wisconsin Engine Parts

Can you still get engine parts for the old 2- cylinder Wisconsin air cooled hay baler engines, such as pistons? Didn"t see much on the Internet search that I did. I think they are "T" series engines?

Not sure it will help, but link below shows several Wisconsin "T" series engine manuals and hopefully parts, good luck.

The twin- cylinder engines were basically half of a four- cylinder, so many parts in common.

Parts book agrees except if 2 cyl. is model TJD.
TF,TFD,TH,THD,and TJD share many parts.
Two different piston lengths. 2.88 inch and 3.38 inch.

Go to Wisconsin Engines official website,
www.wisconsinmotors.com there you can find your
engine and download a parts book. You can also
find a list of distributors where you can get
parts, beware! they price them as if they are
gold plated! OR go to EBAY and do a search under
"Wisconsin Engine Parts", there are 11 pages of
stuff, or "Wisconsin Engine" where you'll find
26 pages of stuff.Beware again! most of those
sellers also think their stuff is gold plated!
And, you need to know part #'s of what you need,
(That's why you down load a parts book) FINALLY-
NAPA Auto Parts has for 2 cylinder engines:Rings
Pistons, valves, valve guides, gasket sets,Carb
kits, fuel pumps, but you need to know your model
number and serial #, as some stuff is "Before"
certain serial number, or "After serial #" NAPA
prices are fair. There's one party on Ebay now that wants $75 for a fuel pump...NAPA's price is
$54. Finally..most 2 cylinder stuff is interchangeable, except pistons, or old style babbot bearing rods, and newer insert bearing rods, and a V4 engine is just two, 2 cyl top
decks on a different base, so parts interchange,
even 4 cyl gasket sets are just two 2 cylinder
sets with a different oil pan,(base) gasket.

Yes, and many of the parts for the twin TE, TF, TJ, and TH engines also fit some of the single-cylinder engines.

Also check the Brown's Railroad Equipment site. He often has odd-ball and regular Wisconsin parts, both new and used.
