CHAPTER 4
Wheels
Track adjustment The distance between the outside edge of the illuminated area of the direction of travel indicators, side marker lights, tail lights and upper rear reflectors and the outside edge of the tyres must be no more than 400 mm (15.72 in) – international requirement. The maximum permissible track widths specified in the vehicle documents for travel on public roads must not be exceeded. Whenever a wheel is changed, the nuts and bolts must be tightened to the following tightening torques: - Front wheels M22x1.5 bolts = 50 kgm (500 Nm); (361.65 lbf ft) - Rear wheels M22x1.5 bolts = 50 kgm (500 Nm); (361.65 lbf ft) After 20 hours of work, all the nuts and bolts fixing the front and rear wheels have to be retightened to the previous torques. Before changing the wheels, ensure that the tractor cannot move and use suitable supports. Use compressed air to fit tyre to rim: this procedure may only be undertaken by specialists with the aid of an extension hose connected up next to the tyre.
n WARNING: FOR WHEELS DISASSEMBLING AND FOR MAINTENANCE AND REPAIR, LIFT THE TRACTOR, USING SPECIFIC TOOLS ONLY. avv047gb
