DISASSEMBLY
1. Check of needle roller bearing
(1) Install the input shaft to the output shaft, and check the needle roller bearing.
Criteria :  There is no abnormal response, bind, noise, and play.
NOTE:
If defective, replace the needle roller bearing with a new one.
2. Radial clearance check
(1) Install the input shaft to the output shaft, and check the radial clearance.
Standard value :  0.029 to 0.072mm {0.00114 to 0.00283in}
Limit :  0.072mm {0.00283in}
NOTE:
If the value exceeds the limit, replace the input shaft, needle roller bearing, and output shaft with new ones.
3. Check of input shaft bearing FR
(1) Check the input shaft bearing FR.
Criteria :  There is no abnormal response, bind, noise, and play.
NOTE:
If defective, replace the input shaft bearing FR with a new one.
4. Removal of needle roller bearing
(1) Remove the needle roller bearing from the input shaft.
5. Removal of synchronizer ring No.2
(1) Remove the synchronizer ring No.2 from the input shaft.
6. Removal of input shaft bearing FR
(1) Remove the shaft snap ring from the input shaft.
CAUTION:
·Keep the shaft snap ring from flying out with a cloth, etc.
·Verify the direction of the parts.
(2) Use the SST to remove the input shaft bearing FR from the input shaft.
SST     899714110
CAUTION:
Apply press pressure to the inner race of the input shaft bearing FR to remove the input shaft and the bearing FR.
INSPECTION
1. Check of synchronizer ring No.2
(1) Apply manual transmission oil to the cone portion of the 3rd gear, and check the clearance between the synchronizer ring No.2 and the 3rd gear while pressing the synchronizer ring No.2 by hand.
Standard value :  0.8 to 1.6mm {0.0314 to 0.0629in}
Limit :  0.8 mm {0.0314in}
CAUTION:
Check the entire circumference of the gear.
NOTE:
·If the value is smaller than the limit, replace the synchronizer ring No.2 with a new one.
·Be sure to use the recommended product or the substitute product for manual transmission oil. (Refer to )
(2) Apply manual transmission oil to the cone portion of the 3rd gear, and check that the synchronizer ring No.2 does not slip in the circumferential direction while pressing it by hand.
NOTE:
·If it slips, replace the synchronizer ring No.2 with a new one.
·Be sure to use the recommended product or the substitute product for manual transmission oil. (Refer to )
ASSEMBLY
1. Installation of input shaft bearing FR
