Iâ€™m going to call this story; â€œYou can use Cub engine valve springs in other places other than the engineâ€
This happened to me about four years ago when I put a clutch in my first Cub I rebuilt.
It was about ten oâ€™clock on a Saturday night and I got some time to put the clutch in my tractor that I was rebuilding. It was late and I was tired but, I wanted to get this tractor together to start prepping for painting. I bolted the pressure plate and disk into place than opened the box of the throw- out bearing and there was a note in it that was hand written which stated â€œthis part is slightly different than original, but it will workâ€. The only thing I noticed was it was made with a little offset, but I thought the clutch adjustment should take care of that. I put the bearing in the throw- out bearing fork and bolted it back together and it fit pretty tight and I remember thinking â€œ the bearing wonâ€™t flop down and catch the transmission input shaft when I put the tractor halves back together, good dealâ€.
Well late that night I got it together and even started the Cub and drove it. I remember I was so excided that I got my tractor running after going to bed I couldnâ€™t go to sleep.
After the Cub was finished one of my sonâ€™s was driving it around and said â€œhe thought the clutch was making noiseâ€. I checked it and sure enough there was some noise, but I pushed the clutch pedal down and release it and it went away. I shrugged my shoulders and said â€œit must be nothingâ€.
A couple of weeks later my dad was cutting the grass with the Cub and he stopped for a break and he noticed a noise coming from the bell housing area. I checked it out and noticed the throw- out bearing face popping against the clutch pressure plate fingers. I remember, laying on my back in the grass looking through the inspection hole wondering â€œwhat the heck is going onâ€. Than I noticed, the throw-out bearing center (inner dimension) was bigger than the original bearing and the center of the bearing was not resting on the transmission input shaft collar housing. After using the clutch the tension where the throw-out bearing slipped into the clutch fork wore in and the throw-out bearing flopped against the clutch pressure plate fingers and was popping back and forth when the engine was running. My stomach felt like it went to my throat. I was thinking how stupid I was not checking the new part against the old. The only thing I knew to do was to split the tractor and put the correct throw-out bearing in.
After thinking about it for awhile this is how I resolved my issue. http://img.photobucket.com/albums/v688/Jackf/100_0690.jpg
I tie strapped a Cub engine valve spring into place to hold the throw-out bearing so it would not hit the pressure plate fingers when the clutch pedal was in the release position. Itâ€™s been four years â€œdown the roadâ€ and the bearing is still working fine.
It didnâ€™t come out the way it should have, but its working.
