Checking Bearing
1. Hold the inner race, and push and pull the outer race in all
directions to check for wear and roughness.
2. Apply transmission fluid to the bearing, and hold the inner race.
Then, turn the outer race to check rotation.
3. If there is any defect, replace it.

Checking Propeller Shaft Ball Coupling
1. Hold the ball coupling outer, and push and pull, and rotate the
ball coupling inner in all directions to check for wear and
roughness.
2. If there is any defect, replace it.
(When reassembling)
• Apply grease to the inner parts of ball coupling and splines of
ball coupling inner.
• When replacing the ball coupling assembly, install the ball
coupling inner (1) with balls so that its ball position inside of ball
coupling outer (2) as shown in the figure.
