Crankshaft pulley assembly

3. Install the crankshaft pulley assembly (5) and plate (4) with the bolt (3).

3 Bolt (3):  343 to 402 Nm {35 to 41 kgfm}

Idler pulley assembly

4. Install the idler pulley assembly (2) with the bolt (1).

Fan belt k Install the wrench to the part (a) of the auto-tensioner (2) securely, and then rotate it. (The spring of the auto-tensioner (2) is strong. If the wrench is loosely installed and rotated, it can accidentally come off and this is extremely dangerous.) k After installing the fan belt (1), slowly and carefully restore the auto-tensioner (2). k Be careful not to get your fingers caught between the pulley and fan belt (1) during work.

5. Insert a wrench in the part (a) (width across flats: 12.7 mm) of the auto-tensioner assembly (2), and install the fan belt (1) while rotating it in the direction of the arrow (b).

Remove And Install Engine Rear Oil Seal

Tools to be used when removing and installing the engine rear oil seal

Method For Removing Engine Rear Oil Seal

Flywheel assembly

1. Remove the top bolt (1 piece) out of the bolts (1) (6 pieces), and install the guide bolt (H).

2. Remove the remaining bolts (1) (5 pieces).

3. Sling the flywheel assembly (2), and remove it.

4 Flywheel assembly (2):

40 kg k Since the faucet joint part of the flywheel is shallow, the guide bolt may fall off suddenly. Be careful not to bring it into contact with you.

•Remove it evenly so that the oil seal does not tilt.

NOTICE

Do not use a drill, etc. since metal chips may enter the engine.

Method For Installing Engine Rear Oil Seal

1. By using the plate (P) and hammer, press fit the rear oil seal (1) into the rear wheel housing (2) according to the dimension (a).

(a): 10 mm

NOTICE

Check that the end surface, corner and the lip sliding surface of the crankshaft are free from a flaw, burr, fin, rust, and etc. before installing the rear oil seal.

2. After press fitting the rear oil seal (1), fill the space between the oil seal lips with approximately 3 cc of grease.

2 Rear oil seal (1):  Grease (G2-LI)

Flywheel

3. Install the guide bolt (H).

4. Install the flywheel (2) with the bolt (1).

REMARK

•Tighten the bolt (1) in the tightening order shown in the drawing.

•Tighten the bolt (1) twice in the tightening order to the following tightening torque. Bolt (1):

3 1st time:

58.8 to 117.7 Nm {6.0 to 12.0 kgfm}

3 2nd time:

186.3 to 196.1 Nm {19.0 to 20.0 kgfm}

• 2 Threaded portion of the bolt (1):  Engine oil

5. Measure the radial runout and facial runout of the flywheel (2) by using the dial gauge (L).

REMARK

•Rotate the crankshaft to measure the radial runout and facial runout.

•If it is out of standard value, take actions by referring to “MAINTENANCE STANDARD”.

•Measurement of radial runout

Standard value: Max. 0.30 mm

•Measurement of facial runout

Standard value: Max. 0.35 mm
