Yep, Tracy is right. We had one on our WD for that purpose. ------------- "Burgie" |

Milking cows! Not really but we switched ours on the C to the old vacuum valve for Surge milkers and the C handled 4 units that way. Did it in 1991 when an ice storm took all the electric poles in the area and we were without power for 6 days. Made everything to do on the farm much harder to do but the C did it's best to help out. I thinks that valve has something to do with ............I don't know. Was told once but forgot. Kerosine engines maybe? ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |

After an hour of lost power from the grid, my father would drive the '56 CA out behind the back of the barn, put one of those valves on the manifold, hook up the hoses and throttle up the ending and milk away(2 milking machines).

In the picture the little spout is broken off - that the vacuum hose from Milker would slide onto.

Like Gary said, there should be a hose barb on there.

I've seen more than one just like that. Without the barb. I don't think it's broke off. I think that petcock has another purpose. Could be wrong though. ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |

That is a little different valve than most I have seen but I'm sure a guy used what was available and I never heard of another reason to have a valve on the intake like that. My BIL still milks and talked about using one on a different colored tractor many times when he was younger. Oh and I have seen more with the hose barb broken or damaged than not. ------------- http://www.ae-ta.com" rel="nofollow - http://www.ae-ta.com Lena 1935 WC12xxx, Willie 1951 CA6xx Dad bought new, 1954WD45 PS, 1960 D17 NF |

I have a WW2 vintage gas generator with a Herculese engine with a petcock on the intake manifold. You spilled some gasoline in there to prime it to get it to start when the choke and hand cranking wouldn't pull it from the up draft carburetor. Gerald J. |

Is it me or is that intake manifold a little different? It appears to be designed specifically so a valve could be located right there near the carburetor. I'm leaning toward Lonn and Gerald's thoughts on this one. I believe some of the real old automobile engines had priming valves; some I think had them for each individual cylinder. Is this an early B with the distillate engine? |

This is a 38B but it doesn't have a starter tank. Here's a wide shot. It doesn't look the same as the manifold on my 41B.

| This valve is on the B125 power units. I would believe it being used for adding fuel. I grew up on a farm that dry chopped the hay and we used an engine drive blower until I was 16 years old. We always used it when hand starting the engine. Two cranks with the choke on, then with it off and this valve open. When the engine fired you covered the valve with your finger as quick as you could. It did help alot in starting. This valve is in the parts book and did come with the engines new. It is not the one for milking cows, those were added by the farmers or dealers. We have a WD with the surge valve on it yet. |

After doing a bit of searching in parts books, I came up with a part number. 214749 for the "COCK", ventilating, manifold. It lists it for use on engines used for powerunits, 125s and 60Hs not Bs,IBs and C tractors. I belive its use was to ventilate a hard starting engine due to flooding. It is not shown to be used on low octane fuel manifolds.
The factory manifolds for tractors must not have had a cock. They either had no threaded hole or if there was a threaded hole it was pluged.
I am not denying that it could be a used as a vacuum resource in a emergency.
None of the original manifolds with the spec plate that I have, have the cock or a place for a cock or plug. Some of the manifolds I have without the spec plate have a cock or a drilled and tapped hole with a plug or a place to drill and tap a hole. Some of my manifolds with or without a speck plate cannot be drilled and tapped as there is no place to drill and tap. I have 9 to look at and there are at least 5 variations in design. Some are AC and some are aftermarket.

That is a newer manifold because it has the 2 bolt holes for the upright muffler. The small plug to the left of center is sometimes used with a hose barb. Bob

Ken, my C has the same exact manifold on it. Actually, that manifold came from the parts tractor my son bought. I was thinking about the power unit hood that came on mine when I got it, and got confused, thinking the manifold might have come from the same power unit. Anyway, the one I have, wherever it came from(most likely an old power unit), is exactly like the one pictured above. No hose barb, though that would work well for a vacuum source. I can tell you that it doesn't run well when your son accidentally leaves the valve open. I was quite puzzled as to what the heck was wrong with it, until I walked to the other side and heard the source of the whistling and snorting.LOL! ------------- I didn't do it! It was a short, fat, tall, skinny guy that looked like me! |
