Manual Transaxle Unit -- Inspection



1. INSPECT 5TH GEAR THRUST CLEARANCE


    Corolla. Zre142 Aze141
  1. Using a dial indicator, inspect the 5th gear thrust clearance.

    Standard clearance:
    0.10 to 0.57 mm (0.00394 to 0.0224 in.)
    If the clearance is not as specified, replace the No. 3 transmission clutch hub, 5th gear, or input shaft rear radial ball bearing.


2. INSPECT 5TH GEAR RADIAL CLEARANCE


    Corolla. Zre142 Aze141
  1. Using a dial indicator, inspect the 5th gear radial clearance.

    Standard clearance:
    0.009 to 0.050 mm (0.000354 to 0.00197 in.)
    If the clearance is not as specified, replace the 5th gear, 5th gear needle roller bearing, or input shaft.


3. INSPECT REVERSE IDLER GEAR SUB-ASSEMBLY


    Corolla. Zre142 Aze141
  1. Using a caliper gauge, measure the inside diameter of the reverse idler gear.

    Inside Diameter:
    Standard Inside Diameter
    mm (in.)
    Maximum Inside Diameter
    mm (in.)
    20.056 to 20.074
    (0.7896 to 0.7903)
    20.074
    (0.7903)
    If the inside diameter exceeds the maximum, replace the reverse idler gear.


    Corolla. Zre142 Aze141
  1. Using a micrometer, measure the outside diameter of the reverse idler gear shaft.

    Outside Diameter:
    Standard Outside Diameter
    mm (in.)
    Minimum Outside Diameter
    mm (in.)
    19.984 to 20.000
    (0.7868 to 0.7874)
    19.984
    (0.7868)
    If the outside diameter is less than the minimum, replace the reverse idler gear shaft.


4. INSPECT NO. 3 TRANSMISSION CLUTCH HUB


    Corolla. Zre142 Aze141
  1. Inspect the sliding condition between the No. 3 transmission clutch hub and the No. 3 transmission hub sleeve.

  1. Inspect the tip of the spline gear on the No. 3 transmission hub sleeve for wear.



5. INSPECT NO. 3 TRANSMISSION HUB SLEEVE


    Corolla. Zre142 Aze141.E351 Manual Transmission Transaxle.Manual Transaxle System.Manual Transaxle Unit  Inspection
  1. Using a vernier caliper, measure the width of the No. 3 transmission hub sleeve groove and the thickness of the claw on the No. 3 gear shift fork, and calculate the clearance.

    Standard clearance:
    0.15 to 0.35 mm (0.00591 to 0.0138 in.) {A - B}
    If the clearance is not as specified, replace the No. 3 transmission hub sleeve and No. 3 gear shift fork with new ones.


6. INSPECT 5TH GEAR


    Corolla. Zre142 Aze141
  1. Using a caliper gauge, measure the inside diameter of the 5th gear.

    Inside Diameter:
    Standard Inside Diameter
    mm (in.)
    Maximum Inside Diameter
    mm (in.)
    34.981 to 34.997
    (1.3772 to 1.3778)
    34.997
    (1.3778)
    If the inside diameter exceeds the maximum, replace the 5th gear.


7. INSPECT NO. 5 SYNCHRONIZER RING MIDDLE


    Corolla. Zre142 Aze141
  1. Check that the No. 5 synchronizer ring middle rotates smoothly.



    Corolla. Zre142 Aze141
  1. Check that the No. 5 synchronizer ring middle does not rotate while pushing it against the No. 3 clutch hub.
