FLYWHEEL INSPECTION [A26M-R (MZR 2.3 DISI Turbo)]

id0510008001c4

Caution

•  Secure the steering wheel using tape or a cable to prevent the steering shaft from rotating after disconnecting the steering shaft. If the steering wheel rotates after the steering shaft and the steering gear and linkage are disconnected, the internal parts of the clock spring could be damaged.

•  Do not rework the dual-mass flywheel if it is distorted.

•  Do not clean the dual-mass flywheel with any kind of fluid. Clean the dual-mass flywheel with a dry cloth only.

•  Do not clean the gap between the primary and secondary mass. Only clean the bolt connection surface and the clutch surface.

1.  Remove the battery cover. (See BATTERY RECHARGING [MZR 2.3 DISI Turbo].)

2.  Disconnect the negative battery cable. (See BATTERY RECHARGING [MZR 2.3 DISI Turbo].)

3.  Drain the engine coolant. (See ENGINE COOLANT REPLACEMENT [MZR 2.3 DISI Turbo].)

4.  Remove the PCM cover No.1. (See PCM REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].)

5.  Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].)

6.  Remove the following parts:

(1)  Battery tray and PCM component (See BATTERY RECHARGING [MZR 2.3 DISI Turbo].)

(2)  Air cleaner component (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].)

(3)  Charge air cooler cover (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].)

(4)  Charge air cooler (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].)

(5)  Front tires (See GENERAL PROCEDURES (SUSPENSION).)

(6)  Splash shield (See SPLASH SHIELD REMOVAL/INSTALLATION.)

(7)  Aerodynamic under cover No.2 (See AERODYNAMIC UNDER COVER NO.2 REMOVAL/INSTALLATION.)

7.  Remove the starter. (See STARTER REMOVAL/INSTALLATION [MZR 2.3 DISI Turbo].)

8.  Remove the front auto leveling sensor. (See AUTO LEVELING SENSOR REMOVAL/INSTALLATION.)

9.  Drain the transaxle oil into a suitable container. (See TRANSAXLE OIL REPLACEMENT [A26M-R].)

10.  Remove the manual transaxle. (See MANUAL TRANSAXLE REMOVAL/INSTALLATION [A26M-R (MZR 2.3 DISI Turbo)].)

11.  Remove the clutch cover. (See CLUTCH UNIT REMOVAL/INSTALLATION [A26M-R (MZR 2.3 DISI Turbo)].)

12.  Remove the clutch disk. (See CLUTCH UNIT REMOVAL/INSTALLATION [A26M-R (MZR 2.3 DISI Turbo)].)

13.  Inspect the rotation of the dual-mass flywheel for play.

(1)  Lock the dual-mass flywheel using the SST (49 E011 1A0).

(2)  Rotate the secondary flywheel clockwise by hand until resistance can be felt.

(3)  Mark the guide pin position on the ring gear of the flywheel.

(4)  Rotate the secondary flywheel counterclockwise by hand until resistance can be felt.

(5)  Mark the guide pin position on the ring gear of the primary flywheel again.

(6)  Verify that the play is within the range of 4 teeth.

•  If the play is 5 teeth or more, replace the dual-mass flywheel. (See CLUTCH UNIT REMOVAL/INSTALLATION [A26M-R (MZR 2.3 DISI Turbo)].)

Caution

•  It may not be possible to rotate the secondary flywheel due to the functionality of the dual-mass flywheel.

In this case, the dual-mass flywheel can be considered normal by reason of the play being within the range of 4 teeth.

14.  Remove the dual-mass flywheel. (See CLUTCH UNIT REMOVAL/INSTALLATION [A26M-R (MZR 2.3 DISI Turbo)].)

Note

•  Correct slight scratches and discoloration using sandpaper.

•  Inspect the runout of the surface that contacts the clutch disc with the dual-mass flywheel installed to the crankshaft.

15.  Inspect the dual-mass flywheel.

―  Cracks

―  Worn ring gear teeth

―  Chipped or cracked ring gear teeth

―  Surface that contacts the clutch disc for scratches, nicks, and discoloration.

•  If there is any malfunction, replace the dual-mass flywheel. (See CLUTCH UNIT REMOVAL/INSTALLATION [A26M-R (MZR 2.3 DISI Turbo)].)

16.  Inspect for locating dowels touching the primary mass of the dual-mass flywheel.

Caution

•  Make sure that the three locating dowels are installed.

•  If the locating dowels are touching the primary mass of the dual-mass flywheel, replace the dual-mass flywheel with a new one.

17.  Visually inspect the secondary mass.

•  If there is any damage, replace the dual-mass flywheel. (See CLUTCH UNIT REMOVAL/INSTALLATION [A26M-R (MZR 2.3 DISI Turbo)].)

18.  Visually inspect the ring gear on the dual-mass flywheel.

am3zzw00008398

•  If there is any damage, replace the dual-mass flywheel. (See CLUTCH UNIT REMOVAL/INSTALLATION [A26M-R (MZR 2.3 DISI Turbo)].)

19.  Inspect the welded area of the dual-mass flywheel for grease leakage.

am3zzw00008399

•  If there is grease leakage, replace the dual-mass flywheel. (See CLUTCH UNIT REMOVAL/INSTALLATION [A26M-R (MZR 2.3 DISI Turbo)].)

20.  Inspect the dual-mass flywheel for the amount of guide pin projection.

am3zzw00008401

•  If not within the specification, replace the dual-mass flywheel. (See CLUTCH UNIT REMOVAL/INSTALLATION [A26M-R (MZR 2.3 DISI Turbo)].)

21.  Inspect the dual-mass flywheel for cracks.

•  If there are cracks, replace the dual-mass flywheel. (See CLUTCH UNIT REMOVAL/INSTALLATION [A26M-R (MZR 2.3 DISI Turbo)].)

22.  Install in the reverse order of removal.

23.  Add the specified amount of specified transaxle oil. (See TRANSAXLE OIL REPLACEMENT [A26M-R].)

24.  Warm up the engine and transaxle, inspect for oil leakage, and inspect the transaxle operation.

Warning

•  Improperly jacking a transaxle is dangerous. It can slip off the jack and may cause serious injury.

Note

•  If the transaxle is overhauled and installed to the vehicle, perform the 'INSPECTION AFTER TRANSAXLE OVERHAUL' and verify that there is no abnormality. (See INSPECTION AFTER TRANSAXLE INSTALLATION [A26M-R].)
