Thankyou to imperial1960 and MTI for the help, I added some fluid to slip clutch in middle if front drive shaft and torpedoed bolt adjustment to spec, yes it was not tight enough, I have also moved my tires wider by 2 inches each side and my chain no longer rub. All I need now is to try out the 4x4 next snow, thanks again for your help. Jerry

Well, a couple of suggestions - perhaps the "chatter" you hear is the "clutch pack" in the mid shaft carrier assembly between the two split driveshafts going to the front axle.  There are a bunch of small metallic discs in there which are really a kind of safety to prevent overdriving the front axle.  They are basically slip clutches which let go when they sense too much torque being applied to them.  They can be noisy when they engage/disengage such as when plowing.

But...since you don't believe the 4wd is really working "enough," you might consider that these clutches have worn somewhat and need adjustment - this is a standard maintenance check according to Belarus and is accomplished as best I can remember by dropping the rear driveshaft and exposing a large nut at the rear of the housing (on the mid-shaft assy) which is then torqued to spec.  That might be a place to start...  I don't remember what the torque spec is, but perhaps someone else has their manuals close by...

As to the tires, it's not really that bad to loosen the axle clamps and move the tires out - if you need more lateral clearance, between the inside of the tire and the side of the wheelwell, you can also reverse the tires to face outwards.  But, if ballasted, these rear tires are very heavy - if you don't have help or equipment, I would suggest a tire guy do it.  If you do move those clamps, make sure you keep checking them after the first tightening - they can loosen up and that can be ugly...

Get someone to watch the front axle check if front drive shaft is turning then see if the two drive shaft turn together when in four wheel drive and going forward.Front wheel drive will disconnect when turning steering far right or left this is normal check center section box between two front drive shafts drive shaft yoke nut could be loose.

Help needed with Belarus 572 4x4

Hi,I have a 572 4 wheel drive that seam to be working some but will not spine the tires unless they have very poor traction no mater if I have the shift in automatic or full time 4 wheel drive, when in full time 4 x 4 the back wheel spin but not the front a it makes a funny noise as if something is slipping. Is there seperate clutch for front wheel drive or can anyone give me some ideas. My second problem is that is use the tractor for snow plowing and put a set of chains on the rear tires but they scub the cab , is it a big job to shit the tires wider, since I have about 1/12 inches to the en of the axle, any help would be good, Thankyou Jerry
