Adjustment oftapered roller bearings of directive wheels of Belarus-90 tractors

Adjustment of tapered roller bearings of directive wheels of Belarus-90 tractors

During the adjustment of bearings of guide wheels, mount axial clearance in the range 0,08-0,20 mm. Control it every 1000 h operating. For this, lift the wheel and, rocking it in the direction, perpendicular to plane of rotation, determine the gap in the bearings. After determine the raised gap, perform adjustment as follows: а) unscrew the bolts and take off the cover 2; b) uncotter the castle nut 1 and turning the wheel from the hand, tight nut 1 until the appearance of raised resistance to the wheel rotation.

Than unscrew the nut so to obtain the coincidence of the nearest cut of the nut with hole under cotter pin in the semiaxis; c) check ease of wheel rotation; d) cotter the nut, put the cap in place provisionally filling it by lubricant.
