[AT] Clutch Shudder

[Cecil Bearden]

I got a chance to look at my new MTZ yesterday.  I got the clutch pedal 
pulled down with a tie down strap, and stuck a big screwdriver against 
the back clutch disk.  I could move it up and down nearly 1/4 inch.    
The intermediate plate was adjusted fine.  After talking with factory 
sales mgr, and service mgr.  I will take it to a shop in western OK that 
had shown interest in MTZ tractors but had not been delivered one.  They 
assured me that they would reimburse me for all expenses in this.   The 
sales mgr is pres. of a dealership that has been in business for 136 
years. He said they changed to MTZ/Belarus when Case/IH became such a 
pain in the butt to do warranty work with.  He said there is no problem 
with Belarus, but the production engineer would like to see what I had 
filmed, and just wanted to be kept in the loop as he was going to send 
some alignment tools and could maybe give some additional information..

   I made a nearly 3 minute video, but I cannot find an editor that I 
can understand how to use.   I only want to send about 15 seconds.   I 
will try tomorrow to make another one but shorter. I tried to send it to 
a dropbox for large files, and after 1 1/2 hours, it stopped and said it 
had a problem...  My video camera is too detailed for long videos.
