OVERDRIVE BRAKE (for 1KD-FTV) INSPECTION


  1. INSPECT PISTON OPERATION OF OVERDRIVE BRAKE


    1. A003DPG

      Place the overdrive support sub-assembly onto the direct clutch assembly.

    2. A003FMQ

      Apply compressed air (392 kPa, 4.0 kgf/cm2, 57 psi) into the oil passage, and check that the overdrive brake piston moves smoothly.

  2. INSPECT OVERDRIVE BRAKE RETURN SPRING SUB-ASSEMBLY

      Measure the free length of the spring together with the spring seat.

      Standard free length
      17.03 mm (0.6705 in.)

      If the free length is shorter than the standard free length, replace the overdrive brake return spring sub-assembly.

  3. INSPECT OVERDRIVE BRAKE CLUTCH DISC

      Check if the sliding surface of the disc, the plate and the flange are worn or burnt. If necessary, replace them.

      Tech Tips


      • If the lining of the disc is peeled off or discolored, or even if only a part of the printed numbers is corroded, replace all discs.

      • Before assembling new discs, soak them in ATF for at least 15 minutes.
