Counter Gear And Reverse Idler Gear -- Disassembly



1. INSPECT REVERSE GEAR THRUST CLEARANCE


    Lexus Is250, Is220D. Gse20 Ale20
  1. Using a feeler gauge, measure the reverse gear thrust clearance.

    Standard clearance:
    0.12 to 0.28 mm (0.0047 to 0.0110 in.)
    If the clearance is outside the specification, replace the defective gear, spline piece or bearing race.


2. INSPECT 1ST GEAR THRUST CLEARANCE


    Lexus Is250, Is220D. Gse20 Ale20
  1. Using a dial indicator, measure the 1st gear thrust clearance.

    Standard clearance:
    0.10 to 0.42 mm (0.0039 to 0.0165 in.)
    If the clearance is outside the specification, replace the defective gear, clutch hub, spline piece or counter gear.


3. INSPECT 2ND GEAR THRUST CLEARANCE


    Lexus Is250, Is220D. Gse20 Ale20
  1. Using a dial indicator, measure the 2nd gear thrust clearance.

    Standard clearance:
    0.10 to 0.42 mm (0.0039 to 0.0165 in)
    If the clearance is outside the specification, replace the defective gear, clutch hub or counter gear.


4. INSPECT REVERSE GEAR RADIAL CLEARANCE


    Lexus Is250, Is220D. Gse20 Ale20
  1. Using a dial indicator, measure the reverse gear radial clearance.

    Standard clearance:
    0.015 to 0.065 mm (0.0006 to 0.0026 in.)
    If the clearance is outside the specification, replace the reverse gear, reverse gear needle roller bearing or bearing race.


5. INSPECT 1ST GEAR RADIAL CLEARANCE


    Lexus Is250, Is220D. Gse20 Ale20
  1. Using a dial indicator, measure the 1st gear radial clearance.

    Standard clearance:
    0.015 to 0.067 mm (0.0006 to 0.0026 in.)
    If the clearance is outside the specification, replace the 1st gear, needle roller bearing or shaft.


6. INSPECT 2ND GEAR RADIAL CLEARANCE


    Lexus Is250, Is220D. Gse20 Ale20
  1. Using a dial indicator, measure the 2nd radial clearance.

    Standard clearance:
    0.015 to 0.067 mm (0.0006 to 0.0026 in.)
    If the clearance is outside the specification, replace the 2nd gear, needle roller bearing or shaft.
