I have a 53 super C without fast hitch.The transmision was making a bad clanking sound while driving in 2nd,3rd,and especially 4th gear.I split the tractor,tore the transmission completelty apart, but found nothing serious.All the teeth on the gears are good,the bearings were a little loose and pitted from sitting,so i replaced ALL the bearings.Got it all back together and painted,drove it out of the shop today and its making the same noise as it was!!! I just have NO CLUE what it could be?? Anyone have any suggestions, or what i should look at next??
 
I have a 400D with the similar problem.
Mine is the bearing on the main shaft. The faster it goes the louder it sounds. Mine has some grinding also. You probable don't hear it in first gear. Get a SC shop manual and it should have a bearing on the main shaft somewhere. I'm not sure if you can check it out without taking it back apart. Hope this helps.
 
Well, you now have a good transmission. Did the same to my Super A, but I have not driven it yet. The noise could also be caused by a loose clamp on the axle or loose rim bolts, they may seem tight, but really aren't. I assume you have already been told all this. It could be an axle bearing. There is an inner and an outer. Remove one rear wheel and try to move the axle. There is not supposed to be any play, or with normal wear, maybe minimal. You might also try pushing the tractor with engine off. SC is not too hard to move if you have concrete.
 
We had a 460 utility awhile back clunked while driving the faster you went the louder it got,turned out to be a bolt that holds tire to hub,good luck
 
the mainshaft and countershaft splines could be worn also. just because the gear teeth looked good the splines could be loose.
 
If your referring to the main drive shaft on the front on the transmission, i changed that bearing also when i had it apart...
 
My dad had a super A with that sound. He went through the transmission and never really found anything that would explain it. He did not want to start buying parts to try so gave up.
 
Had a similar problem on my dads Super C I borrowed from him several years ago. We were pulling out some small stumps when it started clunking when we were driving it.

Now I have been around and broke enough parts to know what that sounds like. I was sure. We tore into the rear end completely. All the gears turned out to be perfect and nothing loose. We put it all back together and dad just drove it for a while because he needed it.

About a week later he called me to say he fixed the clunk. Tightened the front wheels. I was floored. Sure enough.

Been 10 years and we still laugh about that.
 
CRUSHER/LOL, JUST KIDDING OF COURSE. ALL RESPONCES ALL HAVE GOOD MERIT,REMEMBER JUST LIKE CARS ETC, SOUNDS TRAVEL THRU ALL THAT IRON,ITS A HORSE SHOE GAME FIGURING IT OUT. GOOD LUCK, MY IDEAS ARE THE SAME AS EVERYONES ELSE. I HAVE A TRACTOR MAKING NOISE ALSO, FOR AS MUCH AS I USE IT, ITS STAYING NOISY!
 
Did you look closely at the tooth profiles especially the pot metal oil slinger gear. My B Farmall was making a heck of a racket and the tooth profile at the pitch line was worn flat.
Replaced it with a new one....ouch....

Also had timing gears make a racket on a 560, pitch line wear, a good used set took care of that one.
 
Put a dab of finger nail polish on each wheel to rim clamp, and bolt to clamp, and axle to hub joint. Drive it around and look for broken polish. Jim
 
When you have noise, a little diagnostic time can pay dividends. As an example, run the tractor in 2nd gear at a high engine RPM (say 1400 RPM) and note the frequency of the noise at that road speed. Now shift to 3rd gear, maintaining as best you can the same road speed by reducing the engine speed; now increase the engine RPM to the same as 2nd gear RPM (1400) and note the frequency of the noise. If you notice that the noise occurs at the same road speed regardless of what gear you are in, then issue is associated with a tire, wheel or ring/pinion gear. If the noise increases/decreases with the engine RPM in two different gears, it"s associated with the transmission or engine.
