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.

Front

Rear

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.
