TL70 MANUAL TRANSMISSION / TRANSAXLE: COUNTER GEAR: INSPECTION; 2013 MY FR-S [03/2012 -]
1. INSPECT NO. 2 TRANSMISSION HUB SLEEVE
(a) Check that the spline gear edges of the No. 2 transmission hub sleeve are not worn down.
HINT
If it shows any sign of wear, replace the No. 2 transmission hub sleeve with a new one.
(b) Install the No. 2 transmission hub sleeve to the No. 2 transmission clutch hub, and then check that it slides smoothly.
HINT
If it does not slide smoothly, replace the No. 2 transmission hub sleeve and No. 2 transmission clutch hub with a new one.
2. INSPECT NO. 2 TRANSMISSION HUB SLEEVE CLEARANCE
(a) Using a vernier caliper, measure the claw width of the No. 2 gear shift fork.
Standard width:
7.9 to 8.0 mm (0.311 to 0.315 in.)
Minimum width:
7.9 mm (0.311 in.)
HINT
If the width is less than the minimum, replace the No. 2 gear shift fork with a new one.
(b) Using a vernier caliper, measure the groove of the No. 2 transmission hub sleeve, and then calculate the clearance with the No. 2 gear shift fork.
Standard clearance:
0.15 to 0.35 mm (0.00590 to 0.0138 in.)
Maximum clearance:
0.35 mm (0.0138 in.)
HINT
If the clearance exceeds the maximum, replace both the No. 2 gear shift fork and No. 2 transmission hub sleeve with a new ones.
3. INSPECT NO. 1 SYNCHRONIZER RING
(a) Apply manual transmission gear oil to the taper cone of the counter shaft 4th speed gear, and then hold the No. 1 synchronizer ring in position with your hand to measure the clearance between the No. 1 synchronizer ring and counter shaft 4th speed gear by using a feeler gauge.
Standard clearance:
0.8 to 1.6 mm (0.0314 to 0.0629 in.)
Minimum clearance:
0.8 mm (0.0314 in.)
NOTICE:
Check the entire circumference of the gear.
HINT
If the clearance is less than the minimum, replace the No. 1 synchronizer ring and counter shaft 4th speed gear with a new one.
(b) Apply manual transmission gear oil to the taper cone of the counter shaft 4th speed gear, and then hold the No. 1 synchronizer ring in position with your hand to check that it does not slide in the circumferential direction.
HINT
If the ring slides, replace the No. 1 synchronizer ring and counter shaft 4th speed gear with a new one.
4. INSPECT NO. 1 SYNCHRONIZER RING (for 3rd gear)
(a) Apply manual transmission gear oil to the taper cone of the 3rd gear and No. 1 synchronizer ring, and then hold the No. 1 synchronizer ring in position with your hand to measure the clearance between the No. 1 synchronizer ring and the 3rd gear by using a feeler gauge.
Standard Clearance:
NOTICE:
Check the entire circumference of the gear.
HINT
If the result is not as specified, replace the No. 1 synchronizer ring and 3rd gear with a new one.
(b) Apply manual transmission gear oil to the taper cone of the 3rd gear, and then hold the No. 1 synchronizer ring in position with your hand to check that it does not slide in the circumferential direction.
HINT
If the No. 1 synchronizer ring slides, replace the No. 1 synchronizer ring and 3rd gear with a new one.
5. INSPECT COUNTER SHAFT
(a) Using a micrometer, measure the outer diameter of each location.
Standard Outer Diameter:
HINT
If the diameter is less than the minimum, replace the counter shaft with a new one.
(b) Using V-block and a dial gauge, measure the runout of each location as shown in the illustration.
Standard runout:
0.03 mm (0.00118 in.) or less
HINT
If the runout exceeds the standard, replace the counter shaft with a new one.
6. INSPECT 3RD GEAR
(a) Using a cylinder gauge, measure the inside diameter of the 3rd gear.
Standard inside diameter:
43.015 to 43.040 mm (1.69350 to 1.69448 in.)
Maximum inside diameter:
43.040 mm (1.69448 in.)
HINT
If the inside diameter exceeds the maximum, replace the 3rd gear with a new one.
7. INSPECT COUNTER SHAFT 4TH SPEED GEAR
(a) Using a cylinder gauge, measure the inside diameter of the counter shaft 4th speed gear.
Standard inside diameter:
46.315 to 46.340 mm (1.82425 to 1.82441 in.)
Maximum inside diameter:
46.340 mm (1.82441 in.)
HINT
If the inside diameter exceeds the maximum, replace the counter shaft 4th speed gear with a new one.
8. REMOVE 4TH GEAR BEARING INNER RACE
(a) Using a micrometer, measure the outside diameter of the 4th gear bearing inner race.
Standard outside diameter:
46.225 to 46.250 mm (1.81988 to 1.82087 in.)
Minimum outside diameter:
46.225 mm (1.81988 in.)
NOTICE:
Do not measure the oil groove.
HINT
If the outside diameter is less than the minimum, replace the 4th gear bearing inner race with a new one.
