Tension Adjustment EBS00VER
Belt tension is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Removal and Installation EBS00VES
REMOVAL
- Hold the hexagonal part (A) of drive belt auto-tensioner (1) with a wrench securely. Then move the wrench handle in the direction of arrow (loosening direction of tensioner).
- Insert a rod such as short-length screwdriver approximately 6 mm (0.24 in) in diameter into the hole (B) of the retaining boss to fix drive belt auto-tensioner.
- Remove drive belt.

Removal and Installation EBS00VEW
REMOVAL
1. Remove the air duct (inlet).
2. Remove the air cleaner filter from the air cleaner case. Refer to EM-16, "Changing Air Cleaner Filter" .
3. Remove the air duct [between air duct (inlet) and air cleaner case] from the air cleaner case.
4. Remove the PCV hose.
5. Remove the air duct (between air cleaner case and electronic throttle control actuator).
Add marks as necessary for easier installation.
6. Remove air cleaner case with the following procedure.
a. Remove battery. Refer to SC-4, "BATTERY" .
b. Disconnect harness connector from mass air flow sensor.
c. Remove the air cleaner case.
7. Remove the mass air flow sensor from the air cleaner case, if necessary.
Changing Air Cleaner Filter
1. Push the tabs (A) of both ends of the air cleaner cover (1) into the inside (B).
2. Pull up the air cleaner cover forward (C) and remove it.
3. Remove the air cleaner filter (1) and holder (2) assembly from the air cleaner case.
4. Remove the air cleaner filter from the holder.
Movement Amount in Radial (Rotation) Direction
Check the movement amount of radial (rotation) direction with the following procedure:
1. Install clutch cover bolt (1) to clutch cover mating hole, and place a torque wrench (A) on the extended line of the flywheel (2) center line. Tighten bolt at a force of 9.8 N·m (1.0 kg-m, 87 in-lb) to keep it from loosening.
2. Put a mating mark on circumferences of the two flywheel masses without applying any load (Measurement standard points).
3. Apply a force of 9.8 N·m (1.0 kg-m, 87 in-lb) in each direction, and mark the movement amount on the mass on the transaxle side.
4. Measure the dimensions of movement amounts “A” and “B” on circumference of the flywheel on the transaxle side.
