 4. Fill the CSD with Oil (Fig. 301)
_____________________
 A. General
 (1)  
The CSD sight glass has different ranges for the oil level on the left and right engines. This is because the left and right engines are at different angles.

 (2)  
The oil level shown on the sight glass of a disconnected CSD can show more oil than there is. Expanded air can push the oil from the oil cooler into the CSD. To get an accurate indication of the oil level, fill the CSD and look at the sight glass again.

 (3)  
Leakage of the seal in the CSD will let oil flow from the CSD to the spline cavity. A defective input shaft seal will cause these indications:

 (a)  
The oil level in the CSD will decrease.

 (b)  
The oil level in the spline cavity will increase.
