Step 5
Loosen Jam Nut and Set the Bearing Preload
While holding the thru-shaft with the 3/4” (19mm)
open end wrench through the slot in the motor base,
use a 1 1/8” (28mm) deep well socket to loosen the
jam nut by turning it counterclockwise. Loosen the
jam nut 4 full turns and stop. Figure 8 and 9.
While holding the thru-shaft with 3/4” (19mm) open
end wrench, use the spanner socket (weldment) tool
to Loosen the seal nut 2 full turns. Then put a rag on
the spanner socket for padding and tighten the seal
nut as tight as you can by hand to set the bearing.
Figure 8 and 10.
Once the bearing is set, loosen the seal nut 2 full turns.
Hold the thru-shaft firmly with the 3/4” (19mm)
open end wrench and use the spanner socket to hand
tighten the seal nut until it is “snug.” Do not over-
tighten!! Figure 8 and 10.
Then hold the thru-shaft firmly with 3/4” open
end wrench so it doesn’t move at all and set
the bearing preload by carefully loosening the span-
ner socket and seal nut one bolt hole. Then thread
2 - 3/8” thrust housing cap bolts through the holes
in the spanner socket and into the threaded holes in
the thrust housing to hold the spanner socket in that
position. Figure 11.
