Hi, I do not speak English, so I help Google.
Adjusting the overrunning clutch control pedal on the first video shown is not correct. Free running is to adjust the length of the control rods rather than adjusting the squeezing levers !!! Although very, very old literature there are recommendations for adjustment as shown in the first clip. Adjust the position of squeezing levers (if you changed the grip) should be carried out to the tractor connections with the transmission and not through the bottom hatch. And to open the bottom flap should be in the case if you did something wrong when you adjust the clutch.
Ps The first video shows the old-style clutch basket. this basket is not used on the new tractors.

Adjustable pressure plate I see is the guy backing off or turning each finger to get clearance? Sure is alot of grease all over the clutch group Im still learning Thanks


Yeah these are adjustable, you want them all even for when the release bearing pushes against them. Mine calls for 3-4 mm clearance between the release bearing surface and the release fingers. I set them and made sure they were all even when i did my clutch years back and haven't fooled with them since. But i have checked to make sure i had free play on the release bearing and the release fingers.  As a clutch wears the pressure plate pushes closer to the fly wheel causing the release fingers to move out to the release bearing.

Belarus Clutch Info
« Reply #1 on: March 20, 2015, 01:13:35 PM »
Most Belarus tractors (100HP>) have a single disc dry clutch set up. It's basically just like any dry clutch in a smaller hp tractor , car or truck etc.  Dry clutches are a wear item and depending on the type of work you do it may last 10,000 hrs or  500hrs!  All depends on how its abused,  used doing work and adjusted. What you'll find is either it starts slipping when in gear pulling hard or pushing. Or if the clutch disc starts to separate it will drag (stay engaged) making it impossible to shift gears when the engine is running.


The clutch disc, pressure plate, and throw out bearing can all be bought at your Belarus/MTZ dealer, or order them online or what I do is just go to my local clutch & brake - reline shop.  They can reline your old clutch disc,  resurface your pressure plate and fly wheel on a typical clutch service.  Now depending on the situation if the pressure plate is damaged, broken springs, finigers or stuff like that you  then have to order new parts from your  Belarus MTZ dealer etc.

Over time as the clutch wears you have to adjust the free play in the linkages which it shows you in the Belarus owners manual. Also when doing a new clutch on these tractors you can adjust the pressure plate release fingers also which it should explain in your Belarus owners manual.  These tractors also have a grease-able throw out bearing, you remove a plug on the left side of the bell housing to grease the bearing.


I found a couple videos but if anyone has pics or video of doing the clutch on your Belarus just add them to the thread here



The 1st video shows a young fellow adjusting the pressure plate release fingers and clutch pedal. Its not in English but gives you and ideal of whats involved.  The work starts at the 1:47 mark of the video.

The 2nd video shows pics of the tractor split doing an clutch and other things on a air cooled Belarus engine.
