9N been running fine for 20+ years, but today I start it up and have a clacking noise. Noise goes away when I push in the clutch. Noise is there in neutral or any gear, putting the sherman in high the noise is faster. Any ideas what to look for before I start splitting it apart?
 
fzc8md, Try it with the PTO disengaged,with it in neutral and the clutch out, engaged .If no clunking ,then the noise is from worn hydraulic pump parts.
 
Might be worn bearing noise but that usually sounds more like a low
level grinding that clacking noise. Broken gear teeth has a clacking
sound or it could be the ball socket on the shifter handle is worn.
Before splitting try raise the shifter up to see if the noise stops.
 
Thanks for the ideas! Noise is there with upward pressure on the shifter, PTO engaged or not. It does go away putting the sherman in neutral. I'm starting to
think something on the input shaft has failed. I can actually feel the noise in the steering wheel!
 
Jack up the tractor and put it on jack stands. That way you can crank it and sit next to tractor and can listen and can tell if it's Sherman, transmission or hydrolic pump.
 
While sitting on the tractor and the tractor is running, try pulling up on the shift lever. See if the
noise stops.
I have had that problem and rebuilt the shift lever socket in the transmission cover. The cover is
aluminum and the lever is steel. What wears first?
I had one shift lever that half of the ball at the very bottom was worn away from rubbing on the gear.
