Ÿ
Mount hubs on the shaft, leaving
the faces flush with the shaft ends.
Ÿ
Tighten the set screws if the model
has them.
Ÿ
Determine the required clearance
using Table 3. Using a spacer bar
with the obtained thickness, insert
between the hubs at the the same
depth and in 90 ° intervals.
Ÿ
Use a feeler gauge to measure the
gap between the space bar and
hub face. The difference between
the maximum and minimum must
not exceed the specified angular
limit.
Ÿ
Check that the pump-motor
alignment is correct, resting one
square object straight (ruler) at 90°
intervals. Check the clearance with
a feeler gauge.
Ÿ
Proceed to tighten the anchor and
check alignment and clearance
again; if necessary, repeat the
process from the beginning until
you get a proper alignment.
Ÿ
Insert the joint by the clearance
between the hubs and rest it on
any of the covers. Lubricate the
slots and clearance with as much
grease as possible.
Ÿ
Fill the spaces between the grid
and around it with grease. Remove
excess.
Ÿ
Oil the seals to slide on the hubs,
align and assemble the covers,
leaving a displacement of 180 °
between the lubrication holes.
Ÿ
Tighten the screws of the covers
and check for proper assembly of
the seals.

To insert the grid, note that their
segments are radial. To extend as
little as possible, go partially
inserting segments using a soft
mallet. Once the segments are in
position, push them to the bottom
of the grids.
The grid the inner faces (INT) and
external (EXT) are marked for easy
identification.
Ÿ
Fit the covers with the seals (lightly
greased) on the shaft.
