Assembly, “Fan - Remove and Install”.

3.  Remove two bolts (6). Install Tooling (A).

4.  Remove the remaining bolts (6) and spacer (5).

5.  Remove crankshaft pulley (4).

NOTICE

Keep all parts clean from contaminants.

Contaminants may cause  rapid wear and  shortened

component life.

6.  Install a suitable lifting device to vibration damper

(3). The weight  of the vibration damper  is

approximately 36 kg (79 lb). Make a temporary

mark in order to show the front of  the vibration

damper for installation.

7.  Use the lifting device to remove vibration damper

(3) from the crankshaft.

NOTICE

Thoroughly inspect  the viscous  damper for signs  of

leakage  or for  signs  of a  dented  (damaged) case.

Either of  these  conditions can  cause the  weight  to

make contact  with the case. This  can affect the  vis-

cous damper’s operation.

5.  Use the lifting device to align vibration damper (3)

with Tooling (A). Install the vibration damper to the

crankshaft.

9.   Position the V-belts on the crankshaft pulley and

the pulley of the belt tightener.

10. Rotate bolt (2) in order to adjust the tension of

the V-belts. Refer to Operation and Maintenance

Manual, “Belts - Inspect/Adjust/Replace”.

Note: Ensure correct orientation of  the vibration

damper.

6.  Remove the lifting device.

11. Tighten nut (1) in order to lock the position of the

belt tightener.

7.  Install crankshaft pulley (4) and spacer (5).

End By:

8.  Install bolts (6). Remove Tooling (A) and install the

remaining bolts (6). Tighten the bolts to a torque

of 240 N·m (177 lb ft).

a.  Install the fan. Refer  to Disassembly and

Assembly, “Fan - Remove and Install”.

2.  Install a new O-ring seal to crankshaft front seal

(2). A new crankshaft front seal is supplied with a

plastic sleeve. Ensure that the plastic sleeve is

squarely installed within the crankshaft front seal.

Installation Procedure

Note: The plastic sleeve is  included in order to

protect the lip of the seal as the seal is pushed over

the crankshaft flange.

NOTICE

Keep all parts clean from contaminants.

Contaminants may cause  rapid wear and  shortened

component life.

Note: Do not lubricate the crankshaft front seal or

the crankshaft flange. The crankshaft front seal

must be installed dry.

1.  Ensure that the crankshaft flange and the front

cover are clean, dry and free from damage.

3.  Align the plastic sleeve with the crankshaft flange.

Ensure that the plastic sleeve is engaged onto the

crankshaft flange. Push new crankshaft front seal

(2) squarely onto the crankshaft flange.

During this process, the plastic  sleeve will be

forced out of the crankshaft front seal. Discard the

plastic sleeve.

4.  Install nuts (1). Tighten the nuts to a torque  of

12 N·m (105 lb in) in the numerical sequence that

is shown in Illustration 110.

1.  Ensure that the crankshaft is thoroughly clean and

dry. Remove any areas of raised damage.

Start By:

a.  Remove the crankshaft front seal.  Refer to

Disassembly and Assembly, “Crankshaft Front

Seal - Remove”.

2.  Apply a small continuous bead of Tooling (A) to the

inner surface of the crankshaft wear sleeve. Apply

the bead of Tooling (A) 5.00 mm (0.2 inch) from

the chamfered end of the crankshaft wear sleeve.

NOTICE

Keep all parts clean from contaminants.

Contaminants may cause  rapid wear and  shortened

component life.

Note: Wear sleeves are used to reclaim worn seal

surfaces or damaged seal surfaces. Wear sleeves

are not original equipment.

1.  Use a sharp tool to score a deep line across the

crankshaft wear sleeve.

Note: Take care to avoid damaging the crankshaft.
