Adjustment of front wheels toein of the tractors with steering booster

Front wheels toe-in is adjusted at the factory in the range of 0-8 mm. Periodically every 250 h of working and also at every change of the front track check toe-in and when is necessary adjust it. Before checking it, obligatory adjust the gaps in the bearings of the wheels and hinges of the steering links. The adjusting of the wheels toe-in perform in the following order: а) place the tractor at the horizontal ground with hard surface; b) place the pitman (10) in midposition, for this, turning the steering wheel, place it in the position when the probe in the steering booster body is maximum sinked; c) check that the conical pair bodies (for tractors with FDA) or the steering knuckles (for tractors without FDA) are moved out to length «B» from the front axle body or front axle tube correspondingly; d) adjust the left and the right steering links by extending or shortening them to the same value, for this unscrew the lock-nuts (3, 5, 6, 8) and, turning the left and the right tubes (7, 4), set the required length; e) determine the wheels toe-in, for this measure the distance (measurement

«D») between inner flanges of wheel treads ahead (at a height of the wheel centers) and mark by chalk the measurement positions. Then go ahead at the tractor so that the marks are behind at the same height and measure the distance between marked points (measurement «C»).

The second measurement should be larger than the first one; the difference between the second «C» and the first «D» measurements is equal to the wheel toe-in and should be 0-8 mm. When is necessary, adjust the toe-in by changing the length of the steering links. Extend or shorten the left and the right links to the same length; f) check the mounting of the pitman in the midposition (by probe) and the difference of the measurements «C» and «D» again; g) after the final adjustment of the wheel toe-in, lock the tubes of the steering links.
