OPERATION OF SET 77 7. The set is allowed to overheat. The causes of this will be found under the heading, Overheating. 8. Poor oil, into which dirt has been al lowed to enter, has been used. The rings on the bearings have been allowed to dry or have been dipped into oil which has lost its lubricating body. 2. Set is Noisy (a) — This may be due to loose bolting to the absorbing pads, and loose boards under the pads or under the motor generator set. Tighten these bolts and keep the set level. (b) — The bearings may be defective or have been improperly installed. Examine them and note if they run free and without vibration or play. (c) — The set may not be level thereby putting its elements out of alignment. Test the level. (d) — Loose bearings will also cause noisy operation. Xote whether they are loose in the housing or on the shaft and take the necessary steps for correction. (e) — This may also be due to a sprung shaft. This trouble calls for a replacement, unless the shaft can be trued.
