Section F. ADJUSTMENTS

Front track adjustment Steering booster without hydraulic cylinder in steering linkage

Front track can be changed in the range from 1350 to 1850 mm with intervals 100 mm at symmetric and 50 mm at asymmetric wheel arrangement. For arrangement of the required track of guide wheels perform the following operations: а) lift the tractor front part by jack until the wheels break off the ground; b) loosen bolts (1), take out pins (2) mountings of the retractable cams in the tube of front axle; c) at first move the first and then the second retractable cam (6) (simultaneous change the length of steering links by turning tubes (3) in the tips (5), preliminary turning off lock-nuts (4)) at appropriate value of arrangement track and then fix cams in the tube of front axle; d) lower the tractor down. Check toe-in and, if necessary, adjust it.

FDA with bevel gear speed reducers. Steering booster without cylinder in steering linkage

Front track is adjusted by stepless screw mechanism situated at hoses of the front axle at three intervals: 1350-1500 mm, 1500-1600 mm, 1600-1800 mm. To obtain the required width of the track set the adequate relative position of wheel tread relative to the disk as is shown in the figure below. For the wheels with constant disk offset the track is adjusted stepless in the intervals 1400...1600 mm and 1750…1950 mm. To change the track lift the tractor head (or alternately the front wheels) providing with the gap between the wheels and ground, brake the rear wheels and then: а) turn off bolts (4) and uncup (2); b) turning off the nuts, unclamp cotters of the hoses (3) so that provide free movement of the conical pair bodies.

Turning the adjusting screw (1) by the key is provided the movement in the hoses of the front axle of final drives bodies with wheels and obtainment of the required track in the specified intervals. The rotation of the adjusting screw should be accompanied by the change of the length of steering links. 4
