10. Prepare the shaft for assembly as follows (see the illustration):
a) Place the bearing-clamp ring (253B) onto the shaft (122).
b) Fasten the clamp-ring bolts (236A) crosswise.
See the specified torque values.
Make sure that the shaft rotates freely.
c) Install a new O-ring (496).
d) Install the outboard labyrinth oil-seal (332A) into the bearing housing (134).
Place the drain slots of the oil seal at the bottom position (6 o’clock).
Make sure that the edges of the keyway are free from burrs. To protect the O-ring, cover the
keyway lengthwise with a piece of electrical tape before you install the oil seal.
11. Install the shaft assembly into the bearing frame as follows (see the illustration):
a) Coat the outside of the bearing housing (134) with oil.
b) Coat all the internal surfaces of the bearing frame (228) with oil.
c) Install the shaft assembly into the bearing frame (228).
Make sure that the shaft rotates freely.
d) Install the clamp bolts (370C) in the bearing housing (134) and tighten by hand.
e) Install the jack bolts (370D) with the locknuts (423) in the bearing housing (134) and tighten by
hand.
Assemble the rotating element and the bearing frame ( LTi )
CAUTION:
Wear insulated gloves when you use a bearing heater. Bearings get hot and can cause physical injury.
NOTICE: Make sure that the pipe threads are clean, and that you apply thread sealant to the plugs and
fittings. Failure to do so may result in equipment damage or decreased performance.
