 2.  IDG OIL Level Check (Fig. 303)
___________________
 A.  General
 (1)  The IDG oil level check can be done through the IDG access panel, if the engine cowl panels are not open.
 NOTE: If the IDG low oil level indicator is missing, damaged or
____ hard to read, do the IDG oil servicing task.
 (2)  The IDG low oil level indicator shows when the oil level is below the minimum required oil level for safe operation. It does not indicate if the IDG is over serviced. The only way to ensure proper IDG oil level is to hook up the overflow drain hose and add oil to the IDG. If the oil level of the IDG is in doubt, hook up the overflow drain hose and add oil to the IDG.
