Maintenance Instruction
5.6.2 Front drive axle main drive adjustment
Normal axial clearance between front wheel bearings 8 and 9 is
0.05~0.15mm. During the operation, if the clearance is greater
than 0.4mm, the front wheel of the tractor will move from side to
side and the bearing may be damaged by the impact. Therefore, it
is necessary to adjust the clearance immediately. When adjusting,
prop up the front wheel above the ground, remove bearing cap
and pull out split pin 7 of nut 6. Screw nut 6 until the clearance
disappears, return nut 6 by 1/15~1/7 circle, then lock nut 6 with
split pin 7 and install bearing cap.
