Planetary Gearset The planetary gearset comprises a front and rear carrier half, an input shaft, four planet pinion gears, four planet pinion shafts and one hundred and forty four needle rollers. The input shaft is located through the planetary carriers and is driven by the output shaft from the transmission. The sun gear is located on splines on the input shaft and rotates at the same speed. Rotation of the sun gear is transferred to the four pinion planet gears which in turn rotate around an annulus gear located in the front casing and secured with a retaining ring. The rotation of the planetary pinion gears causes the front and rear carriers to rotate. The rear carrier has gear teeth which mesh with the teeth in the sleeve. To smooth the transition of the gear teeth of the sleeve and the rear carrier, an inner and outer blocker ring and a cone are fitted. When the fork moves the sleeve, the three detents in the hub are pushed, which in turn push the inner and outer blocker rings and the cone together. These items mesh together at an angle and operate as a synchromesh to provide smooth engagement of the gear teeth and the transition into low range. The input shaft also has an outer blocker ring and a cone between the shaft and the hub. When the fork moves the sleeve, the three detents in the hub are pushed, which in turn push the outer blocker ring and the cone together. These items also mesh together at an angle and operate as a synchromesh to provide smooth engagement of the gear teeth of the hub and the input shaft and the transition into high range.
