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. 29) • 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. 29 and 30) • 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. JAM NUTS FIG. 30 TO REMOVE WHEEL FOR REPAIRS FRONT WHEEL (See Fig. 31) • Block up axle securely. • Remove axle cover, retaining ring and washers to allow wheel removal. • Repair tire and reassemble. • Replace washers and snap retaining ring securely in axle groove. • Replace axle cover. REAR WHEEL • Block rear axle securely. • Remove five (5) hub bolts to allow wheel removal. • Repair tire and reassemble. Replace and tighten hub bolts securely. NOTE: To seal tire punctures and prevent flat tires due to slow leaks, tire sealant may be purchased from your local parts dealer. Tire sealant also prevents tire dry rot and corrosion.
