Check the static inspection torque of all bolts (2) in outer ring (1) . Only a few of the rotator head bolts (2) will be accessible at a time. Use appropriate tooling in order to apply the torque that is specified in table 1.Note: The shear can be rotated manually in order to replace all of the rotator head bolts (2) . Use a sufficiently long lever in order to rotate the shear.
Table 1
Static inspection torque    
Sales model     Bolt size     Torque value    
VHS-30/3, VHS-40/3, VHS-60/3     M20 x 2.5     460 N m (339.3 lb ft)    
VHS-40/3, VHS-70/3     M24 x 3    
800 N m (590.0 lb ft)    The bolt (2) should not move before a torque that is specified in table 1 is reached. If bolt (2) moves, then the sealant has been broken and the bolt has been overstressed. All bolts (2) in outer ring (1) must then be replaced.ReferenceFor more information on replacing the rotator head bolts, refer to Operation and Maintenance Manual, "Rotator Head Bolts - Replace" for the work tool that is being serviced.
