8.3. The “Parallel Misalignment” value (P) is the offset between the centers of the hubs, as shown in Figure 6.
Figure 6 - Parallel misalignment
9. Coupling Grid installation
9.1. For T20 insert gasket between hubs. Pack gap and grooves with specified lubricant before inserting grid. When grids are
furnished in two or more segments, install them so that all cut ends face eachother (as detailed in the picture below); this will
assure correct grid contact with non-rotating pins in cover halves. Spread the grid slightly to pass over the coupling teeth and
seat with a soft mallet
10. Cover assembly
10.1. Pack the spaces between and around the grid with as much lubricant as possible and wipe off excess flush with top of grid.
T10: Position seals on hubs to line up with grooves in cover. Position gaskets on flange of lower cover half and assemble
covers so that the match marks are on the same side. If shafts are not level (horizontal) or coupling is to be used
vertically, assemble cover halves with the lug and match.
T20: Slide cover halves with seals onto hubs and position with lube holes 180° apart (90° apart for Sizes 1150 thru
1170). Line up cover and gasket bolt holes and secure with fasteners; tighten to torque specified in Table 6
