THE DRIVING SHAFT
Leading the moving cone (pulley) with bearings (six balls) is based on the drive shaft of
the variator and connects to it with the help of the planetary mechanism. Planetary gear is
used for reverse gear. The drive shaft consists of movable and fixed cone. Progress in rolling
cone is 22 mm.
Necessary push force to create friction between the metal belt and pulley cones formed
push-plates in the control cavities rolling cone. Prior to disassembly of the drive with a
planetary mechanism will check the compressed air oil duct and the piston speed ahead with a
seal (botton picture). We take our adapter with a foot pump, through a hole number 1,
we simply blows the channel, passing in the shaft of the planetary mechanism. Through the
channel number 2, we check gasket on the junction of the shaft of the planetary mechanism and
the drive shaft, and serviceability of the piston speed ahead. When applying compressed air to
the channel number 2, the piston compresses the friction, and the shaft of the planetary
mechanism must rotate along with the drive shaft. To access the friction, the piston forward and
the gasket between the shaft should be removed large snap ring 3.
Before removing the piston front of the check again with compressed air work piston. Our
adapter insert into the end of the shaft of the compound planetary gear, leg swing pump and
for the observed motion of the piston. If necessary, fluff brush with oil edge piston for a visa-
Piston forward is one of the weaknesses in the variator. Major failures because of it. Rubber
deposited by curing on a metal part of the piston - hardens and loses elasticity. Height (thick-
ness on) a rubber bumper is only 5 mm, and height of the cylinder in the fixed part of the cone
leading shaft is also small. During compression clutch forward, the piston is so out of the cylin-
der, which creates oil leak on the outer circumference of the piston. Reduced contact area bet-
ween the piston and cylinder. Falling oil pressure ball valve on the piston does not have time
to close. Piston periodically presses, the press clutches. And as a result is obtained:
1. Twitching of the time away.
2. Wear of the friction, they simply burn out. Increased clearances and there is a metal ring.
3. Of clutch friction material are particles that fall into the oil block of solenoid and a valve,
which causes them to malfunction - jamming valve (plunger).
4. Wear surface of the cones.
5. Wear metallic belt.
6. Crushing balls in the slots.
7. Chips in the slots themselves driving and driven shafts.
8. As a result - jamming mobile cones.
9. And later breakage of the metal belt.
10. In the torque converter divides the overrunning clutch.
This photo shows the "native" piston. Piece of gum "bitten" I myself, there is no flexibility at
all, its just not there.
