(1) Indicates the alarm temperature set point that the bearing should be continuously operated at on the specified generator frame size. Shutdown set points are typically 10° C (18° F) higher.
(2) 454-0291 Bearing Lubricant (390g size cartridge) and 454-0292 Bearing Lubricant (450g size cartridge) replaced the obsolete 2S-3230 Bearing Lubricant.
(3) For Australia use only
(4) 1800 frame generators and 3000 frame generators shipped before 2012 use double-shielded bearings with synthetic grease. There are no threaded holes in the bearing brackets for the grease tubes that are used to add grease. Therefore, no grease can be added to the bearings. Beginning in 2012, 1800 frame generators and 3000 frame generators that are shipped will use a single-shielded bearing with 454-0291 Grease. The front and rear brackets contain factory installed grease fittings, therefore, single-shielded bearings must be lubricated periodically. (Exception: 1866HE generators packaged with serial numbers GLM00116, GLM00121, GLM00122, GLM00129, GLM00130, GLM00131, GLM00132, GLM00133, GLM00138, GSJ00163, GSJ00166, although shipped in 2012-2014 time period, use double-shielded bearings, with synthetic grease. There are no grease tubes, and no greasing for these generators).
(5) All 2700 and 2600 frame generators, regardless of ship date, as well as 1800 and 3000 frame generators shipped beginning in 2012, use a single-shielded bearing design. Replacement bearings received from the Parts Division will have a shield on each side of the bearing. The shield facing
