4.2 ROTATIONAL (TWIST) MISALIGNMENT
If the outer circumference of the flanges
are in alignment but the operator is unable
to fit the bolt into any two corresponding
bolt-holes then rotational misalignment may
have occured.
In this case the alignment tool can be
attached to the most accessible point as
misalignment occurs at all bolt-holes to the
same degree.
1.
Attach the alignment tool at the
most accessible/convenient point
(as shown in sections) and use it to
push the flanges out of alignment
until one pair of bolt-holes becomes
parallel.
2.
Insert the bolt into the aligned bolt-
hole and release the alignment tool.
The load will transfer onto the bolt.
3.
Repeat steps 1 and 2 at other points
around the flange until all of the
remaining bolt-holes are parallel and
the rest of the bolts can be inserted.
