TRANSMISSION REMOVAL/REPLACEMENT

Should your transmission require removal for service or replacement, it should be purged after reinstallation and before operating the tractor. See “PURGE TRANSMIS- SION” in the Operation section of this manual.

TO ADJUST STEERING WHEEL ALIGNMENT

If steering wheel crossbars are not horizontal (left to right) when wheels are positioned straight forward, remove steer- ing wheel and reassemble per instructions in the Assembly section of this manual.

FRONT WHEEL TOE-IN ADJUSTMENT

Front wheel toe-in is required for proper steering operation. Toe-in was set at the factory and adjustment should not be necessary. If parts in the front axle or steering mechanism have been replaced or damaged, check toe-in and adjust if necessary.

TO CHECK TOE-IN (See Fig. 28) -

•Position front wheels straight ahead.

•Measure distance between wheels at front and rear of tires (dimensions “A” and “B”).

•Front dimension “A” should be 1/8" to 1/4" less than rear dimension “B”.

TO ADJUST TOE-IN (See Figs. 28 and 29) -

•Loosen jam nuts at adjustment sleeves on tie rod.

•Adjust tie rod until dimension “A” is 1/8" to 1/4" less than dimension “B”.

•Tighten jam nuts securely.

FRONT WHEEL CAMBER

The front wheel camber is not adjustable on your tractor. If damage has occurred to affect the front wheel camber, contact your nearest authorized service center/department.
