Service and care of a forward axis and steering draughts consists in regular check of reliability of fastening and a tightening of nuts 2 (sm fig. 6.21) fingers of steering draughts, lock pins, шкворней bolts of coupling collars of cross-section steering draught; to periodic greasing шкворневого connections; to check люфтов in шкворневых connections and hinges of steering draughts, and also in check of a convergence of wheels.

At check of carving fastenings of a forward axis observe the recommended moments of an inhaling:

- Fingers of steering draughts and клиновых pins шкворней — not less than 70 Н·м (7,0 кгс·м);

- Bolts of coupling collars of steering draughts — 14—18 Н·м (1,4—1,8 кгс·м).

Check of reliability of fastening клиновых pins should attach special significance. At their easing appears люфт and the subsequent fast development of an aperture in a beam that causes of repair or beam replacement.

At greasing carrying out шкворневого connections are necessary for achieving a greasing exit in the top lug of a fist 12 through a special cut in a socket a beam-fist, and in the bottom part — from under an edge of a protective cap of the persistent bearing.

At impossibility прошприцевать шкворневое connection солидолом is recommended to be pumped over preliminary its mix of engine oil with kerosene in a proportion 1:1.

Люфт шкворня in plugs check wheel rocking in a vertical plane, the wheel thus should not concern a floor.

Шкворень and plugs require replacement in the event that their total deterioration has reached sizes of 0,5 mm. It is defined by moving of the case brake скобы (fig. 6.20 see) at wheel rocking. If moving of the top external edge of the case is more 0,5 mm replacement шкворня and plugs is necessary.
