Check the static inspection torque of all rotator head bolts (4) in rotator gear group (5). Use appropriate tooling in order to apply the torque that is specified in table 2. Only two of the rotator head bolts (4) will be accessible at a time through the two inspection holes (6). Check all of the rotator head bolts (4) in rotator gear group (5). Note: Rotate the work tool in order to access all rotator head bolts (4).

Static inspection torque
Sales model Bolt size Torque value
CTV30 M20 450 N m (332 lb ft) Note: The rotator head bolt (4) should not move before a torque that is specified in table 2 is reached. If rotator head bolt (4) moves, then the sealant has been broken and the rotator head bolt has been overstressed. All rotator head bolts (4) in rotator gear group (5) must then be replaced.Reference: For more information on replacing the rotator head bolts (4), refer to Operation and Maintenance Manual, "Rotator Head Bolts - Replace".

Check the static inspection torque of all the upper head assembly nuts (9) on the grapple. Use appropriate tooling in order to apply the torque that is specified in table 4.
Remove the three covers (10) on top of the rotator housing assembly to access the lower rotator head bolts.
Check the static inspection torque of all the lower rotator head bolts (11) on the rotator. Use appropriate tooling in order to apply the torque that is specified in table 4.
Install the three covers (10) on top of the rotator housing assembly. Note: The rotator head bolt (9) and head assembly bolt (11) should not move before a torque that is specified in table
