Lubricate the screws, (pos. 28a), and the nuts, (pos. 36a), with THREAD-EZE. Fit them and tighten diagonally.
See 2. Tightening torques and lubricants.
Before fitting the coupling, check that the forked distance piece, (pos. H), is still inserted between the shaft seal,
(pos. 105), and the seal carrier, (pos. 58).
Fit the coupling, (pos. 8), on the shaft so that the top of the pump shaft is flush with the bottom of the clearance chamber
in the coupling. See fig. 2.

Lubricate the hexagon socket head screws, (pos. 9). Fit the screws, tighten and leave loose.
Check that the gaps either side of the coupling halves are equal.
Tighten the hexagon socket head screws, (pos. 9), two and two (one side at a time). See 2. Tightening torques and
lubricants.
Pull the forked distance piece, (pos. H), free of the shaft, turn it and store it on the screw, (pos. 58a).
