• First loosen the two set screws (hex: 3 mm) in the bearing bushing so that the bearing can
move freely along the axis.
• Then unfasten the two nuts (M8) that fix the flanges to the centre plate (13 mm spanner) and
turn the camshaft downwards.
• The belt can now be removed and replaced.
• Follow the procedure in the reverse order to replace the camshaft, belt catchers and guides.
• For easy reach of the bolts to affix the bearing flange, we recommend to lift the machine at the
front with the special lifting vehicle (read § 11.4.13)
• Because the belt is new and unstretched, the cable length for coupling the belt tensioning
roller must be reset to its minimum position(read § 11.4.3).
• Once maintenance is completed, replace the black cover plate. (read § 11.4.12.)
Second Belt drive (engine - hydrostatic pump)
• Remove the large black cover plate (read § 11.4.12).
• To replace the belt to the hydrostatic pump, the belt to the camshaft of the pulley on the
crankshaft must be taken away also. (Read § 11.4.4)
• For easy removal of the hydrostat belt, the tension must be reduced.
• Unfasten the four fixing bolts (M10) of the engine support plate by one turn (17 mm spanner)
• The tensioning device of the engine support plate can now be moved backwards. Turn the
clamping nut (M10) in the seed reservoir anti-clockwise. If the engine plate does not move
backwards automatically as a result of the belt tension, give the locking nut at the back of the
seed reservoir a clockwise turn (17 mm spanner).
• First take the belt from the hydrostat; once the belt is loose it is easier to place it over the
larger pulley of the adjacent drive.
• When the new belt has been applied, it will have to be tightened. (read § 11.4.3)
• When the belt has the correct tension and alignment, the large black plate cover may be put
back in position (read § 11.4.12)
