Torque Converter And Drive Plate Inspection

Inspect the one-way clutch.

1. Set SST into the inner race of the one-way clutch.
   

   SST

   09350-32014(09351-32010)
   

2. Install SST so that it fits in the notch of the torque converter hub and in the outer race of the one-way clutch.

3. Stand the torque converter up and turn SST.
   

   OK:

   The one-way clutch rotates smoothly when turned clockwise and locks when turned counterclockwise.

Inspect the torque converter assembly.
If any of the following problems are present, replace the torque converter assembly.

1. A metallic sound is emitted from the torque converter assembly during the stall test or when the shift lever is moved to N.
   
2. The one-way clutch turns smoothly or is locked in both directions.
   
3. The amount of powder in the ATF is more than the sample shown in the illustration (refer to the sample).
   

   HINT:

   The sample illustration shows approximately 0.025 liters (0.026 US qts, 0.022 Imp. qts) of ATF that was removed from a torque converter.

Replace the ATF in the torque converter.

HINT:

If the ATF is discolored or has a foul odor, stir the ATF in the torque converter before replacing the ATF.

Clean and check the oil cooler and oil pipe line.

HINT:

1. If the torque converter is inspected or the ATF is replaced, it is necessary to clean the oil cooler and oil pipe line.
   
2. Apply compressed air of 196 kPa (2.0 kgf/cm², 28 psi) into the inlet hose.
   
3. If a large amount of powder is found in the ATF, add new ATF using a bucket pump and clean the oil cooler and oil pipe line again.
   
4. If the ATF is cloudy, inspect the oil cooler.
   

Prevent deformation of the torque converter and damage to the oil pump gear.

NOTICE:

Make sure that all of the bolts are the same length and that the specified bolts are used.

HINT:

If there is any damage to the tip of a bolt for the torque converter or to the bottom of a bolt hole, replace the bolt and torque converter.

Check the drive plate for damage.

Set up a dial indicator and measure the runout at the 6 areas on the drive plate surface that contact the torque converter.

Maximum runout:

0.30 mm (0.0118 in.)

HINT:

If the runout is more than the maximum or the drive plate is damage, replace the drive plate (HILUX_TGN26 RM00000147M02AX_01_0134.html).
