B1, B3 BRAKE AND F1, F2 ONE-WAY CLUTCH INSPECTION





1. Using vernier calipers, measure the free length of the piston return spring.

B3 brake return spring free length:
Standard: 15.72 mm (0.62 in)

^ If it less than the specification, replace the piston return spring with a new one.





2. Inspect the lining of all drive plates. (133)
^ 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.

B1 brake return spring free length:
Standard: 17.05 mm (0.67 in)

^ If it less than the specification, replace the piston return spring with a new one.





4. Inspect the lining of all drive plates. (B1)
^ 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. Verify that the F1 one-way clutch rotates when the bearing race is secured and rotated clockwise, and that it does not rotate when the bearing race is rotated counterclockwise.





6. Verify that the F2 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.
