grinding and noisy clutch when disengaged

Anonymous-0 · Feb 10, 2009

On a 1952 Farmall Cub, we had trouble shifting(diengaging the clutch) adjustments were made but, now when the cluch pedal is depressed, we hear a loud grinding as if we are over driving the cluch into something and can not get the tractor in gear. Viewing the release bearing from underneath, it appears ok and the cluch travel appears to be adequate to put pressure on the clutch release levers. Any suggestions before we need to split the tractor.

Sounds like you need to check the clutch adjustment for one inch of free travel with pedal all way out until you feel the throw out bearing come in contact with the pressure plate as you depress the clutch. There should also be a stop screw to keep the pedal from being pushed down too far and causing the fork/carrier to the throw out bearing from contacting the pressure plate. Only other thought would be that the clutch is stuck or the flywheel or pressure plate or both are rusty, causing the clutch not to release. Will the tractor stop if it is in gear when the engine is started? If not, the clutch is stuck. Put the transmission in high gear and with the pedal depressed, rock the tractor back and forth until it comes loose. This is the only time a 6 year old should be pushing the clutch.

probably a bad release bearing

I went throught this on my '49 cub last summer when I split it to replace the rear main. It is out of adjustment. That loud grinding you hear is the forks for the TOB hitting the Pressure plate. If you don't have the book, get one. I don't remember the exact procedure, I do remember, it wasn't much fun, hour on my back looking through that little hole, working with a right angle screwdriver. In the mean time go to farmallcub.com, and search te archives, or ask. Very helpfull folks who are crazy about these great little tractors. Hope you've got small hands, I don't.

Good luck.

Your out of adjustment !

There are two ways of adjusting it, depending on thr year.

1st. On the clutch pedal under the foot board there is a bolt that is in a slot .

2nd. Is under neith and must be done threw the access window in the bell housing.

When it grinds it is pushing the throw out bearing to far into the presure plate.

You should also adjust the fingers so that there is 1 1/4" between the clutch pressure plate and tip of clutch fingers. If you don't adjust your clutch, you may end up breaking the fingers off the pressure plate.
