1. Inspect the lining of all drive plates. (C1)
-
• If the lining is flaking or has changed color, or if it is worn or the print mark is wearing away, replace it with a new drive plate.
• When replacing, inspect the contact surfaces between the retaining plate, driven plate and drive plate.
• If they are scratched or have changed color, replace with new parts.
-
Note
-
• Before replacing with new drive plates, soak them at least 2 h in ATF.
2. Inspect the lining of all drive plates. (C4)
-
• If the lining is flaking or has changed color, or if it is worn or the print mark is wearing away, replace it with a new drive plate.
• When replacing, inspect the contact surfaces between the retaining plate, driven plate and drive plate.
• If they are scratched or have changed color, replace with new parts.
-
Note
-
• Before replacing with new drive plates, soak them at least 2 h in ATF.
3. Using vernier calipers, measure the free length of the piston return spring.
-
C1, C4 clutch return spring free length
-
Standard: 26.29 mm {1.04 in}
-
• If it less than the specification, replace the piston return spring with a new one.
4. Inspect the lining of all drive plates. (C2)
-
• If the lining is flaking or has changed color, or if it is worn or the print mark is wearing away, replace it with a new drive plate.
• When replacing, inspect the contact surfaces between the retaining plate, driven plate and drive plate.
• If they are scratched or have changed color, replace with new parts.
-
Note
-
• Before replacing with new drive plates, soak them at least 2 h in ATF.
5. Inspect the lining of all drive plates. (C3)
-
• If the lining is flaking or has changed color, or if it is worn or the print mark is wearing away, replace it with a new drive plate.
• When replacing, inspect the contact surfaces between the retaining plate, driven plate and drive plate.
• If they are scratched or have changed color, replace with new parts.
-
Note
-
• Before replacing with new drive plates, soak them at least 2 h in ATF.
6. Using vernier calipers, measure the free length of the piston return spring.
-
C2 clutch return spring free length
-
Standard: 20.02 mm {0.79 in}
-
• If it less than the specification, replace the piston return spring with a new one.
7. Using vernier calipers, measure the free length of the piston return spring.
-
C3 clutch return spring free length
-
Standard: 21.03 mm {0.83 in}
-
• If it less than the specification, replace the piston return spring with a new one.
8. Using a dial gauge, measure the inner diameter of the input shaft component bushings.
-
Input shaft component bushing inner diameter
-
18.000—18.025 mm {0.7087—0.7096 in}
-
Caution
-
• Measure at different places and take an average. If it exceeds the specification, replace the input shaft component with a new one.
• When the input shaft component is replaced, inspect the contact surface opposed to the intermediate shaft.
• If the surface of it is scratched or has changed color, replace the intermediate shaft with a new one.
9. Using a dial gauge, measure the inner diameter of the clutch hub bushings.
-
Clutch hub bushing inner diameter
-
Front side: 23.037—23.062 mm {0.90697—0.90795 in}
Rear side: 23.037—23.062 mm {0.90697—0.90795 in}
-
Caution
-
• Measure at different places and take an average. If it exceeds the specification, replace the clutch hub with a new one.
• When the clutch hub is replaced, inspect the contact surface opposed to the input shaft component.
• If the surface of it is scratched or has changed color, replace the input shaft component with a new one.
10. Using a dial gauge, measure the inner diameter of the clutch hub component bushings.
-
Clutch hub component bushing inner diameter
-
Front side: 33.312—33.337 mm {1.31150—1.31248 in}
Rear side: 33.312—33.337 mm {1.31150—1.31248 in}
-
Caution
-
• Measure at different places and take an average. If it exceeds the specification, replace the clutch hub component with a new one.
• When the clutch hub component is replaced, inspect the contact surface opposed to the clutch hub.
• If the surface of it is scratched or has changed color, replace the clutch hub with a new one.
11. Verify that the F4 one-way clutch rotates when the clutch hub is secured and rotated clockwise, and that it does not rotate when the clutch hub is rotated counterclockwise.
