What do I have? 661?

ccaissie · Oct 10, 2016

Rebuilt a carburetor on what I was told was an 800 series Ford w/5 speed and live PTO. When I pulled and identified the carb, it was a TSX 765 which fits the 134 engine, so the TSX 769 kit I had bought was wrong. Got that straightened out, and it runs well now.

The hood has an 800 insiginia, but I was then told by my client that it wasn't original. Serial numbers aren't any help...they run consecutively in each model.

Also, I noticed that the carburetor bolt spacing was narrow, and the intake manifold had slots, so a larger 800 carb could theoretically fit.

So, this mongrel could be an 861 with a smaller carb for the 134 engine, or a 661.

How do I tell?

Stamped right near the serial number on the transmission housing will be the model number, however someone could have swapped in a different engine and the 134 and larger 172 look the same from the outside, but I believe you can tell by the block casting number I recall seeing a list somewhere

Well if you know where the serial number is which is sort of under the battery on a flat spot that has 2 bolt holes under that spot will also be the model number which is above the serial number. But if that is not where you got the numbers then your in the wrong place

Block casting # will I'd the size of the block.

Forget the trans and hood, coil be swaps. Block will tell all.

Ps, you can make a 172 run good on a 134 carb, make it sip fuel as well. Yes, you lose a few hp, but the due savings are nice if you dont need every last cubic inch .

I mow with a 950 with a 134 carb, a little tuning and dinking and it still spins a 5 or 6' mower fine, and sips fuel, still stronger than my 660. My 850 loader tea to with big carb is a gas hog!

The part number for the block is located on the lower right side of the engine and will tell you the cu in. Using the info below you can determine the years used, not the specific year. . The casting code can be broken down to the month day and year it was produced. Although you may be able to ID the engine it may be a replacement. The only way to really tell if it is original to the tractor is to get all the casting codes and compare manufacturing dates. If they are close in date of manufacture you may have an original tractor, If considerably different you may have a mutt. Check the archives as there are threads telling how to decipher the codes.

Here's a list of the part numbers for the 134 and 172 engines.

Go the the rear in the tractor and look up below the top link. is it smooth like this 600/601 rear. Or does it look like the next photo?

Or is it recessed into the rear case like this 800/801?

Very good sirs, I now believe it's an 800 series with 5 speed, live PTO....861

With a 134 carburetor. I like the idea that it will sip gasoline, especially since the float is fixed and it doesn't empty the client's gas tank on the ground.

What do I have? 661?
