    (4) Rotator head bolt (inner ring)

  1. Check the static inspection torque of all 36 rotator head bolts (4) 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-60     M20 x 2.5    
    460 N·m (340 lb ft)    

    Note: Rotate the work tool in order to access all rotator head bolts on the inner ring.

    Note: The rotator head bolt (4) on the inner ring should not move before a torque that is specified in Table 1 is reached. If the rotator head bolt (4) moves, then the sealant has been broken and the rotator head bolt has been overstressed. All rotator head bolts (4) on the inner ring and the washers on the inner ring must then be replaced.

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

  1. Install the cover plate (2) and the bolts (3) .
