Illustration 1 g02174758
Check the static inspection torque of all rotator head bolts (2) in outer ring (1). Only a few of the bolts 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    
S365C     M20 x 2.5    
450 N m (330 lb ft)    
S385C     M24 x 3    
800 N m (590 lb ft)    The bolt should not move before a torque that is specified in table 1 is reached. If the bolt 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.
