  1. Position the work tool in an upright position just above the ground.

  1. Stop the machine engine in order to prevent inadvertent movement of the work tool.

    Note: The host machine must be equipped with a boom lowering control valve in order to perform this procedure. If the host machine is not equipped with a boom lowering control valve, contact your Verachtert dealer.

    (2) Rotator head bolt (inner ring)

  1. Check the static inspection torque of all 24 rotator head bolts on the inner ring. Use appropriate tooling in order to apply the torque that is specified in Table 1. Only one rotator head bolt will be accessible at a time through the inspection hole. Check all of the rotator head bolts on the inner ring of the rotator.

    Table 1
    Static inspection torque    
    Sales model     Bolt size     Torque value    
    VT-50     M20 x 2.5    
    460 N·m (340 lb ft)    

    Note: The rotator head bolt (2) on the inner ring should not move before a torque that is specified in Table 1 is reached. If the rotator head bolt (2) moves, then the sealant has been broken and the rotator head bolt has been overstressed. All rotator head bolts (2) on the inner ring and the washers in the inner ring must then be replaced.

    ReferenceContact your Verachtert dealer for replacement of the rotator head bolts.
