Name this Sound

Cabin fever setting in ----------so I did some YouTube on my warm weather project. This guy put together a nice series of videos on a 44 A project. This is the last one he shows and he has it running. He mentions the growl noise but I am hearing a popping noise too is it a open or missing compression release petcock. Any guess on the growl. He basically did a in tractor ring and bearing job. whttps://www.youtube.com/watch?v=8IZoar9QSV0

Second link above has the collection of A videos scattered about some, early episodes posted after the recent ones, interspersed with random fixes and projects on other things.


Yeah, not much of a guess though. He just made a gasket for the governor cover and put it on, since the one that came in the gasket kit was the 'wrong' one, so fan gear has excessive backlash in that critical area where this class of mechanic has no business going to start with unless told about how setting that backlash is kinda important and THIS is the reason that particular gasket isn't in the kit to begin with. Likely he didn't notice or clear the oiling hole for the upper governor area either which is inside the external oil gauge fitting connection to the governor case. Probing the 'bottom' of that removed fitting with a very fine and stiff wire will both find it and clear it if he pushes hard enough straight forward. I just drilled mine out with an extra long 1/16 inch drill bit available at most hardware stores in particular ACE. You can also just hook on shop air to the 1/8 NPT threads at the gauge hole and give it 30 seconds of full air pressure. If you hear a loud pop and then hiss, it's clear. It tends to foul up with the sludge seen on his governor shaft as he discusses that part in another video. So likely with excessive backlash in the fan gears there is zero oil getting to it as well because the oiling hole remains plugged. Mine is a 44 as well, I had my case 'clean room' clean such you could eat your lunch off it and if I had not spent a half hour with it on my lap giving it the once over for worn mag end bearing bore issues, I would not have found that oiling hole myself.

His description of the alternator connections and purposes is going to give me nightmares. BUT he seems to be a much better doer than he is a teacher, in other words what ever he says isn't quite how the job gets done. He seems to have the alternator done right, he just can't verbalize it such that someone else can believe a word of it. Much less come away with a clear understanding of how it is supposed to be connected and/or works. His method requires zero engine speed to excite, it will make juice right off coming up to idle as the engine starts up. Or any time afterwards when the switch is pulled into the first position.

Popping noise is quite noticeable, but to me an open petcock has a swish sound to it in conjunction to the pop of it, so I don't think it's a petcock since there is no swish. AND this defect is quite noticeable, a child in the second grade would point it out. This guy is certainly a lot better than that. It does sound like the right side though and it does sound like a sharp exhaust leak, perhaps the manifold had a high spot on it on that side or gap and it's not down on the gasket properly?

I picked up on the popping noise too. Could be the mic was just distorting a normal sound or maybe the sound is real. I could hear the popping from the back of the tractor so I'm ruling out manifold gasket.

Well he takes things better then I do I would go batty trying to get the noise located and fixed but thats just me. His video showed me a path to follow and he did do a good filming it.

Lee I didn't watch all of them but the ones I needed were helpful.

Could it be just the echo off the tin shed he had it under??

I know whenever I run a tractor up next to a tin building there's always an awful echo noise. Plus the camera he's using isn't the greatest.

? Anybodys guess, like I said I couldn't live like that.Rough running and or
not normal noise drive me nuts. I know get a life.

Oh, no doubt. He is doing a great service by documenting his various projects like that, it's what YouTube is all about too. No complaints here except his not quite right advice up there too. But where else do we get to see a genuine governor shaft being fiddled with by a large screwdriver as he questions the proper order of the bearing/bushing stack along with the ages old where do the feet really go question. He relates that he found a shaft in the junkyard laying about and it was just like this one so now he's not going worry anymore. And it is properly in order and put together right. We can still have such questions answered in full by guys just like this. Thanks for letting us know it was even up there, I wouldn't have found it for years without your pointer.

It's quite rare to find such an extensive coverage of our very own up there too, first I've seen with this number of episodes, I've added his main video list to my address list myself and will be back for what I need to see. The guy genuinely means well, and that alone puts him on the list of good people.

Ya its not perfect and I am sure the correct police would have a few valid points but all and all for someone at my skill level a look see inside other than a book gives me.Glad I posted it.Glad you liked it.

The mag that you have fires ever rotation and is firing on the exhaust also, what it is unburned fuel in the exhaust stroke. Probably doesn't do it under a load or does it? My 2 pennies. Good luck

Had this exact similar experience not long ago on an unstyled B that I helped a group of FFA/4H kids to as a project. That weird popping noise turned out to be the "high dollar/quality" reproduction muffler causing it. Why, we don't know. Disconnected the exhaust pipe off the manifold and noise went away. I imagine it has to do with the baffle design inside the muffler? Not sure. First one I ever seen do that. Very annoying anyway. Old muffler rotted away long ago and did not have an original spare lying around to test. If you held your hand (wearing a glove) close over the end of the muffler while running, it would also curtail that noise.

FYI
