Toyota RAV4>> Transmission>> The repair and adjusting work performed on cars with the automatic transmission>> Replacement of sealing cuffs
Leak of transmission liquid most often happens because of wear and aging of sealing cuffs of power shafts or the drive of a speedometer (the speed sensor). Replacement of these rings comes easy as they can be replaced, without removing the transmission from the car.
Replacement of cuffs of power shafts
Sealing cuffs are located transmissions on each side, in places where power shafts connect to semi-axial gear wheels of differential. At leak of liquid through sealing cuffs of power shafts side surfaces of a case of the transmission will be covered with transmission liquid.
Lift the car on the elevator.
Remove a power shaft.

Fig. 9.10. Removal of a sealing cuff of a power shaft


Edge of the screw-driver or stripper take out a cuff from a groove in a differential case, at the same time do not damage a surface of a groove (fig. 9.10) .
Clear a groove for installation of a cuff.
Oil engine an external surface and a working edge of a new cuff.
By tubular mandrel with outer diameter, a little smaller, than the outer diameter of a cuff, establish a cuff in a groove. Make sure that the cuff is established without distortion.
Depth of installation of a sealing cuff concerning a groove end face in the case of differential, mm:
– the right side on models from 1996 to 2001       –0,5... + 0,5
– the left side on models with one leading bridge from 1996 to 2001       4,7... 5,7
– both parties on all-wheel drive models from 1996 to 2001       –0,5... + 0,5
– both parties on models with one leading bridge since 2001       –0,5... + 0,5
– the right side on all-wheel drive models since 2001       –0,5... 1,5
– the left side on all-wheel drive models since 2001       –0,5... + 0,5
Establish a power shaft, at the same time do not damage a working edge of a sealing cuff.
Replacement of a sealing ring of the sensor of speed
Two sensors of speed are installed in the transmission: one controls the frequency of rotation of a main shaft, another — a secondary shaft. They are fixed equally: the bolt supporting them at the required level. Sealing is carried out by a sealing ring of round section.
For replacement of a sealing ring disconnect the electric socket of the sensor, turn out a bolt and remove the speed sensor from a transmission case.
Edge of the screw-driver remove a sealing ring from the sensor, establish a new sealing ring and grease it with transmission liquid.
You make installation in the sequence, the return to removal.
Replacement of a cuff of the transfer case on all-wheel drive cars
Remove the driveshaft.
Edge of the screw-driver take an old cuff, at the same time do not damage a groove surface for installation of a cuff and a vent of a shaft.
Clear a groove for installation of a cuff.
Oil engine a surface of a new sealing cuff.
By tubular mandrel with outer diameter, a little smaller, than the outer diameter of a cuff, establish a new cuff in a groove. Make sure that the cuff is established without distortion on depth from 1,1 to 1,9 mm.
Grease vents and the external surface of a flange contacting to a sealing cuff, and install the driveshaft.
