NOTES
Bolts should only be gripped as tight as a pen.
When a slight drag can be felt on the cap lock, the bolt is at 95% of its required torque.
For each configuration of 19 bolts the following minimum cap tightness is required for a
module to be operational.
At least 15 bolts should be at 100% of the correct torque setting, that is no rotation when
held like a pen.
Should a number of low tension bolts be concentrated in a particular area them something
significant may have occurred re-tightening and subsequent close monitoring would be
prudent.
b.
Remove
(1)
Remove friction grip nut (1) washer (2) and rotabolt (3).
(2)
Replace any defective friction grip nuts (1) and rotabolts (3) as required.
NOTE
The friction grip bolts are supplied with plastic sleeving fitted around the shank. Do not
remove the sleeving, the sleeving is used to centralize the bolt in its mating hole.
