Step 5
Loosen Jam Nut and Set the Bearing Preload
While holding the thru-shaft with the 3/4” (19 mm)
open end wrench through the slot in the motor base,
use a 1 1/8” (28 mm) 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” (19 mm)
open end wrench, use the spanner (weldment) tool
to loosen the seal nut 2 full turns. Then put a rag
on the spanner tool 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” (19 mm) open
end wrench and use the spanner tool to hand tighten
the seal nut until it is snug. Do not overtighten!!
Do not allow the 3/4” wrench to move at all!!
Figure 8 and 10.
Continue to 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
spanner tool and seal nut 1/4 turn (90
0
). 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 tool in that
position. Figure 11.
