Transfer Assembly -- Inspection



1. CHECK TRANSFER INPUT SHAFT


    Hilux. Tgn26, 36 Kun25, 26, 35, 36 Ggn25
  1. Using a micrometer, measure the diameter of the transfer input shaft journal surface.

    Minimum diameter:
    47.59 mm (1.8737 in.)
    If the diameter is less than the minimum, replace the transfer input shaft.


    Hilux. Tgn26, 36 Kun25, 26, 35, 36 Ggn25
  1. Using a dial indicator, measure the inside diameter of the transfer input shaft bushing.

    Maximum inside diameter:
    39.14 mm (1.5409 in.)
    If the inside diameter is more than the maximum, replace the transfer input shaft.


2. CHECK FRONT TRANSFER DRIVE CLUTCH SYNCHRONIZER RING (for Manual Transmission)


    Hilux. Tgn26, 36 Kun25, 26, 35, 36 Ggn25
  1. While pushing in the front transfer drive clutch synchronizer ring, try to turn the ring in both directions. Check that the ring cannot be rotated.



    Hilux. Tgn26, 36 Kun25, 26, 35, 36 Ggn25
  1. Using a feeler gauge, measure the clearance between the front transfer drive clutch synchronizer ring and transfer input shaft spline.

    Standard clearance:
    1.05 to 1.85 mm (0.0414 to 0.0728 in.)
    Minimum clearance:
    1.05 mm (0.0414 in.)
    If the clearance is less than the minimum, replace the front transfer drive clutch synchronizer ring.


3. CHECK PLANETARY PINION GEAR THRUST CLEARANCE


    Hilux. Tgn26, 36 Kun25, 26, 35, 36 Ggn25
  1. Using a feeler gauge, measure the thrust clearance of the pinion gear.

    Standard clearance:
    0.11 to 0.84 mm (0.00434 to 0.0330 in.)
    Maximum clearance:
    0.84 mm (0.0330 in.)
    If the clearance is more than the maximum, replace the transfer low planetary gear assembly.


4. CHECK PLANETARY PINION GEAR RADIAL CLEARANCE


    Hilux. Tgn26, 36 Kun25, 26, 35, 36 Ggn25
  1. Using a dial indicator, measure the radial clearance of the pinion gear.

    Standard clearance:
    0.009 to 0.038 mm (0.000355 to 0.00149 in.)
    Maximum clearance:
    0.038 mm (0.00149 in.)
    If the clearance is more than the maximum, replace the transfer low planetary gear assembly.


5. CHECK TRANSFER DRIVE SPROCKET THRUST CLEARANCE


    Hilux. Tgn26, 36 Kun25, 26, 35, 36 Ggn25
  1. Using a feeler gauge, measure the thrust clearance.

    Standard clearance:
    0.10 to 0.25 mm (0.00394 to 0.00984 in.)
    Maximum clearance:
    0.25 mm (0.00984 in.)
    If the thrust clearance is more than the maximum, replace the drive sprocket.


6. CHECK REAR TRANSFER OUTPUT SHAFT


    Hilux. Tgn26, 36 Kun25, 26, 35, 36 Ggn25.Vf2A Transfer 4Wd Awd.Transfer System.Transfer Assembly  Inspection
  1. Using a micrometer, measure the diameter of the rear transfer output shaft journal surface.

    Minimum diameter for A:
    27.98 mm (1.1016 in.)
    Minimum diameter for B:
    36.98 mm (1.4561 in.)
    If the diameter is less than the minimum, replace the output shaft.


7. CHECK TRANSFER DRIVE SPROCKET RADIAL CLEARANCE


    Hilux. Tgn26, 36 Kun25, 26, 35, 36 Ggn25
  1. Using a dial indicator, measure the radial clearance between the drive sprocket and output shaft with the needle roller bearing installed.

    Standard radial clearance:
    0.010 to 0.055 mm (0.000394 to 0.00216 in.)
    Maximum radial clearance:
    0.055 mm (0.00216 in.)
    If the radial clearance is more than the maximum, replace the transfer drive sprocket sub-assembly or needle roller bearing.


8. CHECK TRANSFER HIGH AND LOW CLUTCH SLEEVE AND NO. 2 TRANSFER GEAR SHIFT FORK CLEARANCE


    Hilux. Tgn26, 36 Kun25, 26, 35, 36 Ggn25
  1. Using a feeler gauge, measure the clearance between the clutch sleeve and No. 2 gear shift fork.

    Maximum clearance:
    0.25 mm (0.00984 in.)
    If the clearance is more than the maximum, replace the transfer high and low clutch sleeve or No. 2 transfer gear shift fork.


9. CHECK FRONT DRIVE CLUTCH SLEEVE AND NO. 1 TRANSFER GEAR SHIFT FORK CLEARANCE


Hilux. Tgn26, 36 Kun25, 26, 35, 36 Ggn25
  1. Using a feeler gauge, measure the clearance between the clutch sleeve and No. 1 gear shift fork.

    Maximum clearance:
    0.25 mm (0.00984 in.)
    If the clearance is more than the maximum, replace the front drive clutch sleeve or No. 1 transfer gear shift fork.
