Adjust equipment as required. Recheck steps 2 and 3 after
tightening the foundation bolts and realign the coupling, if the
offset and angular measurements exceed the values in Table
1. Note: Best coupling alignment is obtained by using dial in-
dicators. If dial indicators are used, always rotate the hub on
which the indicator is mounted to obtain readings.

Fill the hub gap and grid teeth grooves with KOP-FLEX

grease or a comparable alternate. Lightly open the grid to
engage with the grooves on the hub. Use a soft mallet to seat
the grids in the tapered teeth grooves. For tapered grids that
are supplied with more than one segment, make sure all the
segment’s open ends are on the same side.

5. COVER INSTALLATION & LUBRICATION
Pack the grid with additional KSG grease or the equivalent
and wipe off the excess flush with the top of the grid. Slide
seals over the hub and adjust to line up with the cover seal
grooves. Place gaskets on both flanges of the lower cover
and install top cover. Align cover match marks on the same
side. For vertical applications or inclined shafts, make sure
the match marks are UP, or on the higher side. Tighten the
cover fasteners to the cover bolt torque value specified in
Table 1. For lubrication, remove the two lube plugs from the
covers and fill with KOP-FLEX
®
KSG grease or specified al-
ternate, until the grease starts seeping out from the other lube
hole. Re-install the two lube plugs in the covers and tighten
securely.
Note: Do not operate coupling without the lube plugs.
