When mounting, use maximum possible bolt size and secure gear drive to rigid foundation. Periodic inspection of all bolts is recommended. 2. Align all shafts accurately. Improper alignment can result in failure. Use of flexible couplings is recommended to compensate for slight misalignment. 3. Arrange the drain and breather plug per your mounting position as indicated on page 2. The breather plug should also be located in the Fill position. 4. Auxiliary drive components (such as sprockets, gears and pulleys) should be mounted on the shafts as close as possible to the housing to minimize effects of overhung loads. Avoid force fits that might damage bearings or gears. 5. Gear drives are nameplated for 1 RPM Input Speed and Class Service. For lower Input Speeds and other Service Class, refer to catalog rating information 6. Input Speeds of 1 and lower are shown in catalog rating tables for speed reducing applica tions. This does not represent the maximum speed. Since speed limitation is based on pitching velocity and varies with size and ratio.Shaft Mounted Installation Mount reducer on the shaft to be driven, as c
