If the vacuum drops and the unit overheats in service, check the gyro supply voltage. Any trouble which results in overheating is likely to result in a reduction of vacuum even though the case is tight and has been properly evacuated. For this reason the vacuum may continue to drop because the lowered vacuum results in overheating which further reduces the vacuum. These volatiles reduce the vacuum more when the case is hot than when it is cold. The trouble may be due to a leak, in which case it will continue to get worse, or it may be caused by volatiles within the casing. Read, on "Adjustments and Balances" before disassembling any parts or making any adjustment.Ī gyro unit may lose vacuum for several reasons. When the simpler checks have been made and the trouble is not found, check other possible causes. Go over the possible causes carefully and make the simplest checks first. It is important to remember that WHEN TROUBLE IS ENCOUNTERED THE FIRST THING TO DO IS TO DISCOVER THE SOURCE OF THAT TROUBLE. There follows a table which is intended to be of help in finding the source of various troubles which may be encountered.
