Adjusting front wheel toe-in on trac-
tors with steering booster
Manufacturer sets the front wheel toe-in
withing the range of 0 to 8 mm.
Periodically after each 250 service hours
as well as at each change of front wheel
track check and as necessary adjust the
wheel toe-in. Before checking, adjust
clearances in the wheel bearings and
steering rod joints.
To adjust the wheel toe-in, proceed as
follows:
a) install the tractor on a horizontal hard
surface;
b) set the pitman arm (10) to the middle
position, to do that, turning the steer-
ing wheel, set it to a position when the
dipstick in the steering booster hous-
ing is buried to a maximum extent;
c) check that the conical pair housings
(for tractors with FDA) or steering
knuckles (for tractors without FDA) be
extended to the length “
Б
” from the
front axle housing or front axle tube
respectively;
d) adjust the left and right steering rods,
lengthening or shortening them to the
same value, to do that, loosen the
locknuts (3, 5, 6, 8) and by rotating the
left and right tubes (7, 4), set the re-
quired length;
e) determine the wheel toe-in by measur-
ing the distance (measurement “
Г
”)
between the inner flanges of wheel
rims in front (at the wheel center
height) and chalk marks in the meas-
urement points. Then drive the tractor
ahead by a distance, when the marks
be at the rear at the same height and
measure the distance between the
marked points (measurement “
В
”).
The second measurement must
be greater than the first; the differ-
ence between the second “
В
” and
first “
Г
” measurements is equal to the
wheel toe-in and must be 0 to 8 mm.
As necessary, adjust the toe-in by
changing the steering rod length. At
that, lengthen or shorten the left and
right rods by the same amount.
f) again check setting of the pitman
arm to the middle position (by dip-
stick) and the difference between the
measurements “
В
” and “
Г
”;
g) lock the steering rod tubes after final
adjustment of wheel toe-in.
