Drive Plate Part Number
DRIVE PLATE PART NUMBER: FN11 19 370
DRIVE PLATE PART NUMBER: FNE1 19 370
12. 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 or similar tool.
(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/cm2, 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. step (4) value step (5) value = 3-4
(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 inch)
Drive plate part number: FNE1 19 370 1.10 - 1.40 mm (0.043 - 0.055 inch)
^ If not within the specification, remove the snap ring and measure its thickness.
(8) Add the thickness to the average value calculated in step (7), and select the snap ring whose range includes the value.
Snap ring sizes
(9) Install the selected snap ring and perform steps (2) to (7) again. Verify that the calculated value satisfies the clearance specification.
13. 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/cm2, 57 - 63 psi)
14. Install the 3-4 clutch component to the 2-4 brake drum.
15. Apply petroleum jelly to the bearing, and secure it onto the 3-4 clutch component.
16. Install the 3-4 clutch hub.
17. Apply petroleum jelly to the bearing, and secure it onto the 3-4 clutch hub as shown in the figure.
18. Install the rear sun gear plate onto the 2-4 brake drum.
19. Install the snap ring.
