THE DRIVEN SHAFT
Driven by a movable cone (pulley) with bearings (only has nine balls) is based on the
output shaft of the variator. The drive shaft consists of movable and fixed cone. Progress is
also rolling cone is 22 mm. Necessary push force to create friction between the metal belt and
pulley cones formed by push-plates and a spring in the control cavities rolling cone.
Before lifting the rolling cone with the driven shaft check the compressed air oil duct
shaft and sealing peripheral devices rolling cone (bottom photo). To the end of the shaft (4)
connected the adapter and serve compressed air and can be seen seeping from the air. The
motion of the rolling cone, we can not observe, as overcome the resistance of the spring foot
pump is not possible, we need up to 60 kg/cm².
Remove the movable cone to check the status of nine balls and grooves on the shaft. Unsc-
rew the nut (1), remove pinion gear (2) and gear locking mechanism driven shaft(3). Proceed
as with the drive shaft, hits the butt of a soft board and fetch a movable cone and nine balls.
Visually check the condition of the balls and grooves on the shaft. Grooves should be clean
without chipping at the edges. Round balls with no dents (not square).
Do not round balls and chips in the slots are the main cause breakage of the metal belt
because wedged moving cones driving and driven shaft. What do I need to do to balls and the
grooves were bad? We must sharply away from rest, braking sharply to moving cones worked
crushing balls and chips were produced in the grooves of rolls.
TIP-TOUCH AND BRAKE SMOOTHLY!
