reassemble them to avoid any mix up in parts or damage to the surfaces at the partings.
7. When removing the labyrinth seals, make note of the position of the anti-rotation button
located on the inside of the top half of the seal. Pull up the garter spring surrounding the
floating labyrinth seal and carefully slip out the top half. Rotate the garter spring until the
lock is visible. Twist counterclockwise to disengage the lock, remove the garter spring, then
rotate the lower half of the seal out of the groove in the bearing housing while noting the
orientation of the oil drain holes. Note the condition of these floating labyrinth seals. If they
are cracked or chipped, they must be replaced. Do not attempt to reuse a damaged seal.
8. To remove the bottom bearing half, the shaft must be raised a slight amount to relieve
pressure on the bearing. On the rear end, this can be done by jacking or lifting on the shaft
extension. (Care must be taken to protect the shaft from damage.) On the front end, jacking
or lifting can be done using bolts threaded into the tapped holes provided in the shaft end.
Note: Lift only enough to free the bearing; overlifting the shaft can cause difficulty in removal of
the bearing.
9. Roll the bottom bearing half to the top of the shaft journal and then lift it using suitable
eyebolts threaded into the holes provided. Again avoid any contact with the shaft shoulders
that could damage the bearing thrust faces. Place the lower bearing half on a clean, dry
surface to protect the parting surfaces.
