- The gearing for each axle is a combina tion of a spiral bevel ring gear and pin ion and a planetary unit.
- First reduction (High Range) is pro vided by the spiral bevel gearing.
- Second reduction (Low Range) is through the planetary gearing. Four planetary idler pinions are confined within the ring gear internal teeth. The planetary gears rotate around a sliding clutch gear.
- Each axle is equipped with a shift unit, which operates the sliding clutch gear to provide a means for selecting the axle range. Range selection is accomplished through the movement of the sliding clutch gear in and out of engagement with low...

- Description and Operation
- Two-Speed, single or tandem, are dual range shiftable axles. They provide low and high range gearing and are designed for heavy-duty service in on-off highway operations. Low range for deep gear reduction and slow speed hauling off highway. H...
- The complete tandem axle assembly includes two axle units, each with double gear reduction capability coupled by a 2-gear power divider.
- The planetary double reduction axles share their basic design concepts and many components with the dual range tandem. The principle variation is the permanent engagement of the double reduction feature. A stationary sun gear, fixed in engage...
