6. Fill the Spline Cavity with Oil (Fig. 302)
_______________________________
A. General
(1)
Correct oil level is determined by removing the cap from the drain fitting and filling the spline cavity until oil comes out of the drain fitting. If when you remove the cap from the drain fitting, more oil comes out of the drain fitting other than the small amount that is normally contained in the standpipe, the oil level was too high.
(2)
Leakage of the seal on the accessory gearbox will let oil flow from the accessory gearbox to the spline cavity. If the oil level in the spline cavity is usually too high, the accessory gearbox seal can be defective.
(3)
Leakage of the seal in the CSD will let oil flow from the CSD to the spline cavity. The input shaft seal can be defective if these two indications occur after you fill the CSD with oil:
(a)
The oil level in the CSD decreases.
(b)
The oil level in the spline cavity increases.
