Carrier 17/19EX - Manual (Page 242)

If the bearing cap does not seat completely, remove and reset the floating labyrinth seal
position. When installing upper bearing cap the floating labyrinth seals sometimes rotate
and the anti-rotation ‘‘tab’’ does not seat in its holder, thus preventing the bearing housing
from seating properly. This procedure should be repeated until the bearing cap seats prop-
erly.
14. Reinstall the bearing housing split bolts. Before torquing bearing housing cap bolts, rotate
shaft by hand while bumping bearing housing with a rubber or rawhide mallet in the
horizontal and axial planes to allow the bearings to align themselves to the shaft journals.
15. Torque the bearing housing cap bolts by following the torque values as provided in Table 6 .
CAUTION CAUTION
!
Do not force bearing cap down. Damage could occur to the labyrinth seals.
