I just finished putting a clutch in a new to me 1950 8N. Previous clutch has sheared the friction material and disintegrated. Fired her up and the clutch is working great, however, I am now onto problem #2. She has a distinct growl/grind when the clutch is engaged. I bought it with the bad clutch, so I have no way of knowing if the noise existed before the clutch replacement.
When I push the clutch in, the noise goes away completely. I believe this eliminates the release bearing. Side note, I bought a new release bearing but this tractor had a lip on the carrier and the old one did not slip off, unlike my other 8n, where the bearing slid right off.
The gear oil is the typical milky white from sitting outside with a bad shifter boot. I am thinking about splitting the front and back and tearing out all the bearings to hunt down the problem. I have never worked inside the tranny on these guys but the shop manual makes the job seem pretty easy. Is there any special tools I would need to pull the mainshaft and countershaft? Also, what should I look for to find the noise? I am assuming bearings but you guys know better than me. I searched the forums but there is not much discussion on the tranny rebuilding procedures.
Thanks!
UPDATE: The bearings and cups are pitted pretty badly and the main drive input gear is badly pitted.
Main drive input gear -- pitted pretty badly
Counter shaft fourth gear chipped
Mainshaft bearings pitted
Bearing cups pitted
Reverse drive gear chipped
