Title: Clutch problems
Post by: Ky Belarus on January 05, 2016, 01:42:07 AM
My clutch pedal does not come back up, I can pull it up with my foot. I just purchased this 560, it had set about 2 years. The clutch doesn't appear to slip, although I have yet to put it under a heavy work load

Have a look at the pivot points on the clutch linkages and see if something is seized up 1st. Then go from there. If it all is good pull off the inspection cover at the bottom under the clutch and have a look. This post maybe of help.  http://www.mtztractortalk.com/mtz-tractors-old-models/belarus-clutch/

On the rear of the tractor looking at the left side to the rear of transmission follow clutch linkage you will see a coiled spring.This spring if its still there adjusts the return clutch linkage.

I have a similar issue with my 562.  The clutch itself seems to fully engage but the pedal just doesn't seem to want to return all the way by itself.  I followed the adjustment procedure in the manual I have.  That procedure contains a note that I found odd.  In step 5, after the upper and lower clevis pins have been removed from the clutch bell crank, the procedure instructs to adjust the return spring adjusting bolt (the larger spring) so that when the pedal arm is pulled downward from the floor pan 1.5 to 2 inches and released, the pedal will return.  The note for this step says: "NOTE: Pulling the pedal arm down too far will cause it to go over-center".  The reason I find this odd is because mine seems to go over-center during normal operation, with everything connected.  This is what seems to keep my pedal from returning- the return spring rotates downward and causes resistance to the pedal returning rather than helping it to return.
I admit that I have not taken the time to check the adjustment of the clutch itself, but I don't really see how that could affect the pedal returning freely since the clutch seems to be engaging OK and it is just the linkage that seems to be binding because of the return spring going over center - also, my manual says to perform the linkage adjustment correctly first.
I have attached two pictures of the clutch linkage on my tractor.  The first shows the forward part of the linkage which includes the smaller spring, and the second shows the rearward part of the linkage which includes the larger return spring.  Concerning this larger spring, the one on my tractor seems to be located differently than the one pictured in my manual and different than others I have seen pictured elsewhere.  As you can see, mine is located at the lower rear corner of the plate that it is mounted to while others I have seen pictured seem to be attached to the upper rear corner of this plate.  Is yours attached low on this plate like mine or high?  I don't really see how I could relocate it to the higher position so that everything hooks up correctly.  Until I can figure out the right way to correct the issue, I have installed a spring between the rear part of the clutch arm and the bottom of the cab floor so that the arm is pulled back up.  This works really well.
I hope at least these pictures can be of some help so that someone knowledgable can point out what needs to be done.

Prince your pic number 2 is the same as shown on my 562.My rear spring fell out in the middle of the road but before it fell out my linkage would not return to normal so I checked the gap between the throw out bearing and the fork which had no clearance.This is when I adjusted picture number 1 linkage to get my gap then the rear coil pack threaded to the same spot.Not sure if this is correct way Belarus shows but it has worked for me.

I have managed to get that strained out, I tightens the larger coil spring up, and keeled soaking the linkage in oil, and after some snow removal, it broke free

Well, clutch is some times the main issue of tractors. If i am not wrong it was the clutch which was the reason behind the Lamborghini company.
