Toyota RAV4>> Coupling>> Coupling switching off bearing
You make removal of the bearing of switching off of coupling as follows:
Switch off ignition and disconnect a wire of "weight" from the rechargeable battery.
Remove the transmission.

Unclench the fixing spring and remove a fork of switching off of coupling from a hairpin with a spherical finger, then remove the bearing of switching off of coupling (fig. 8.7) .
You make check of the bearing of switching off of coupling as follows:
Check a condition of the release bearing which has to rotate easily, evenly and silently and in it there has to be no side play.
The working surface of the bearing influencing a press spring has to be smooth, without cracks, local corrosion or development.
Do not wash out the bearing, immersing it in solvent.
You make installation of the bearing of switching off of coupling as follows:
Apply a thin film of high-temperature lubricant on the following details (the layer of lubricant has to be thin and uniform, otherwise during the coupling work excessive lubricant will be rejected on the working surfaces of coupling that can break its work):
– internal cavity of the bearing of switching off of coupling;
– vents of a main shaft of the transmission;

– the directing plug of the bearing of switching off of coupling (fig. 8.8) ;
– the pads of a fork of switching off of coupling contacting to the coupling switching off bearing;

– in a point of contact of a fork of switching off of coupling with a hairpin with a spherical finger (fig. 8.9) .
Install the bearing on a coupling switching off fork.
Install the bearing on the directing bearing plug on the forward side of the transmission, at the same time the fork has to enter an opening in a coupling case.
Press a fork before accurate fixing it on a hairpin with a spherical finger.
Apply a thin film of high-temperature lubricant on the working surface of the bearing of switching off of coupling contacting to a diaphragm spring.
You make further installation in the sequence, the return to removal.
