8200 SERIES TRACTORS 2G01.12
Splitting - Rear wheels / Hubs
Long straight shaft (Fig. 2 to 8) 5. Unblock screws (5). Using a trolley jack of suitable capacity, lift the appropriate side of the tractor. Finish slackening the screws by a few turns. 6. Take the "V" screw from the tractor toolbox (see Fig. 9), this is a special device for changing the tread. 7. Remove the push-on "plastic" protectors from the tapped holes in male single cones (8), adaptor (12) or the "cast iron" disk (depending on option). 8. Lubricate, install and tighten the "V" screw uniformly and alternately to extract taper-fitting (Fig. 9). 9. Remove any traces of mud or dried earth on the stubshaft (3). Assisted by an operator, pull or push on the wheel in order to slide the cone or the male single cones on the shaft to obtain the sought position. Note: Circlip (6), installed on the end of the shaft, is to limit the axial travel of the taper fitting.
Special point: - The tapered part of male single cones (8), adaptor (12) or the "cast iron" disk (depending on option) must not be greased. Before assembly, clean and dry the parts. On the other hand, the stubshaft must be lightly coated with "Antiseize" grease or equivalent, along the full length, in order to avoid any corrosion spots and thus facilitate travel movement of the wheel during treadchanging.
Danger - When removing tractor wheels, use lifting equipment and a suitable sling.
