Noisy Super A transmissions and cork gaskets

Just wondering how much the cork gaskets that were original equipment on these tractors that were located between the left fender and transmission would help to quieten the straight cut gears?
I gave a 100 and 130 and neither have the cork gasket but not sure it would be worth the effort to add them. Any thoughts from anyone whose tractor has the cork?
Thanks!
 
AFAIK, they were FELT pads and I wouldn't hold my breath that installing them will quiet the transmission much.
 
don't know where you came up with the idea that a cork gasket was used on the fenders as no such a thing happened and I have had lots of the As apart there. Someone is pulling your leg
 
Not sure if it was a CORK gasket but the CaseIH website DOES show a pad of some type of material in between the fender and the transmission. It may be felt as the other poster suggested.

A poster in a thread a few dozen down the page says the pad is "jute".

Bob,
As noted by Gene, I also have removed many fenders on these tractors and have never encountered ANY type of material in between the fender and transmission but after seeing the parts breakdown on the CaseIH website with a LINER of some sort, there obviously was something but it may have disintegrated over the years.
And, since all these tractors were more than 40 years old before I worked on them doesn't mean the LINERS weren't there when the tractors were new.
If not to suppress noise, any idea of what its purpose might be.
Thanks
 
To me, it just makes sense that separating the fender from the transmission with some type of material SHOULD prevent the fender, as large as
it is, from transferring the noise and vibration from the transmission.
I'm not going to remove the fender JUST for adding the gasket, but next time the fender is removed, I'm going to add a piece of felt, cork,
jute or something and see if it helps.
Thanks for your help.
 
It wasn't fastened to anything just placed loose between the fender and tranny and over the years caused rust on the fender sometimes it even rusted the fender thru that's what happens with tractors setting outside
 
My Super A had the Felt pad between the fender and the transmission. Probably to stop rubbish getting jammed in the gap and causing corrosion. The parts book also show the felt pad.
 
Your post and others indicate there was actually something between the fender and transmission. I can't remember if the CaseIh website shows a liner on the other side of the axle, but if not, they must have thought it would have some sound dampening effect on the transmission noise.
 
My '39 A didn't have one when I took it apart. I think if it had one it might have been installed to dampen the fenders vibrations. The down side of that is, felt would have retained moisture causing the left fender to rot out a bit faster than the normal accumulation of crud that finds it's way between the fender and trans.

Possibly something that was added per a Technical Service Bulletin?
 
The CaseIh website indicates there is only one on the transmission fender so I am still prone to believe it was there to dampen noise. If it was
there to prevent crud, etc. it seems there would have been a felt liner on both fenders.
Anyway, thanks for your information.
 
Vibration Dampeners might do the trick. See the link. To figure it out, when it is howling along, grip the top of the fender with your hand. Human flesh has energy absorbing properties. Touching a tuning fork stops the tone. Placing your hand at various places on the fender will assess the resonant points that make the most improvement. There are rubber blocks with weights, and assorted other types. The one shown clamps on to an edge to absorb a variety of frequencies. Jim

I never found a trace of the pad on my Super A, which doesn't imply it never had one.
Did notice the felt pad in the parts book and felt (pun intended) that it was a cheap albeit potentially effective method of transmission noise attenuation. So, I think I will add such pad upon reassembly.
 
I intend to add a liner to mine next time it is apart. It can't hurt anything. I appreciate everyone's response and helpful insight.
 
I also have a noisy drive train on my B only when going forward, some in all gears, more in 4th. There is hardly any noise when in reverse. Would one be able to pull the axles from each side and swap sides and then do the same with the large bull gear. That would give you a newer surface to be meshing against and seems like it should be quitter. Any thoughts?
