15. Measure the 3-4 clutch clearance.

(1) Install the 3-4 clutch in the end cover, and set

the dial gauge.

(2) Secure the 3-4 clutch by lightly pressing down

with a press, etc.

(3) Apply compressed air to the part indicated in

the figure and let the 3-4 clutch piston stroke
three times.

Air pressure

392—441 kPa {4.0—4.5 kgf/cm

2

, 57—63 psi}

(4) Apply compressed air and operate the 3-4

clutch piston. Read the value when the
indicator of the dial gauge stops.

(5) Release the compressed air and read the dial

gauge when the 3-4 clutch piston is not
operating.

(6) Calculate the 3-4 clutch clearance according

to the following formula:
step (4) value – step (5) value = 3-4 clutch clearance.

(7) Measure the clearances at four locations (90

°

apart) by following the steps from (3) to (6).
Verify that the average value is within the
specification below.

3-4 clutch clearance

Drive plate part number : FN11 19 370

1.00—1.30 mm {0.039—0.051 in}

Drive plate part number : FNE1 19 370

1.10—1.40 mm {0.043—0.055 in}

(8) If not as specified, remove the snap ring and

measure its thickness.

(9) Add the thickness to the average value

calculated in step (7), and select the snap ring whose range includes the value.

(10)Install the selected snap ring and perform steps (2) to (7) again. Verify that the calculated value satisfies

the clearance specification.

16. Inspect the 3-4 clutch operation.

(1) Install the 3-4 clutch drum to the end cover.
(2) Inspect the 3-4 clutch operation by applying

compressed air as shown.

Air pressure

392—441 kPa {4.0—4.5 kgf/cm

, 57—63 psi}

17. Install the 3-4 clutch component to the 2-4 brake

drum.

18. Apply petroleum jelly to the bearing, and secure it

onto the 3-4 clutch component.

19. Install the 3-4 clutch hub.
20. Apply petroleum jelly to the bearing, and secure it

onto the 3-4 clutch hub as shown in the figure.

21. Install the rear sun gear plate onto the 2-4 brake

drum.

22. Install the snap ring.
