MISCELLANEOUS WHEELS
FRONT WHEELS—
TOE-IN & CAMBER
Reason:
To insure tractor toe-in is within specification.
Procedure:
Measure toe-in using the following procedure:
1. Equalize front tire pressure (12 psi).
2. Turn wheels so they are pointing straight ahead. If
one wheel has more toe-in than the other, use
steering wheel logo to determine straight ahead.

3. Measure distance (A) from the floor to the center of
wheel hub.
4. Mark the front and rear of each tire at the same
height as measured from the floor. Make a mark
(X) on the center rib of each tire.
5. Push front of both tires outward, simultaneously.
6. Measure distance (B) between marks on front of
tires.
7. Measure distance (C) between marks on rear of
tires.
8. Subtract front measurement from rear
measurement to determined toe-in value.
NOTE: If toe-in is NOT within specification, order and
install adjustable tie rod service kit. This kit will
correct toe-in if one wheel has noticeably more
toe-in than the other. Excessive toe-in of both
wheels will require two kits.
Procedure:
Measure camber using the following procedure:
1. Equalize front tire pressure (12 psi).
2. Turn front tires straight ahead.
3. Use a square to establish a vertical surface to
measure from.
4. Measure distance from top edge of rim (not tire) to
square.
5. Measure distance from bottom edge of tim (not tire)
to square.
6. Subtract top measurement from bottom
measurement to determine camber value.
