  90. INSPECT NO. 4 BRAKE DISC

    A01DUXWE01

    1. Replace all the discs if one of the following problems is present: 1) a disc, plate or flange is worn or burnt, 2) the lining of a disc is peeled off or discolored, or 3) the grooves or printed numbers have even a little bit of damage.

      Note

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

  91. REMOVE REAR PLANETARY GEAR ASSEMBLY

    A01DVC5

    1. Remove the rear planetary gear assembly from the case.

      Remove the 2 thrust needle roller bearings from the rear planetary gear.

    3. A01E2FOE02

      Remove the No. 9 thrust bearing race from the case.

  92. INSPECT REAR PLANETARY GEAR ASSEMBLY

    A01DZ8E

    1. Using a feeler gauge, measure the rear planetary pinion gear thrust clearance.

      Standard clearance
      0.2 to 0.6 mm (0.00787 to 0.0236 in.)
      Maximum clearance
      0.65 mm (0.0256 in.)

      • If the clearance is more than the maximum, replace the planetary gear assembly.

    2. A01DY0Z

      Using a dial indicator, measure the inside diameter of the rear planetary gear bush.

      Maximum inside diameter
      20.075 mm (0.790 in.)

      • If the inside diameter is more than the maximum, replace the rear planetary gear assembly.

  93. REMOVE 1ST AND REVERSE BRAKE RETURN SPRING SUB-ASSEMBLY

    A01DX9FE02

    1. Place SST on the spring retainer and compress the brake return spring.

      SST
      09350-30020   ( 09350-07050 )

    2. Using SST, remove the snap ring and brake return spring.

      SST
      09350-30020   ( 09350-07070 )

  94. INSPECT 1ST AND REVERSE BRAKE RETURN SPRING SUB-ASSEMBLY

    A01DVUK

    1. Using a vernier caliper, measure the free length of the spring together with the spring seat.
