1.  If the ring gear was removed, follow Steps 1.a

through 1.c in order to install a new ring gear to

the flywheel.

Typical example

3.  Install Tooling (A) to  positions (X) on  the

crankshaft.

gear (3).

4.  Install a suitable lifting device to flywheel (2). The

weight of the flywheel is  approximately 50 kg

(110 lb).

Note: The chamfered side of the ring gear teeth must

face toward the starting motor when the flywheel is

installed. This will ensure the correct engagement of

the starting motor.

5.  Use the lifting device in order to position flywheel

(2) onto Tooling (A). Ensure that Marks (Y) on the

flywheel and on the crankshaft are aligned.

b. Heat ring  gear (3) in an oven to a maximum

temperature of 316  °C (600 °F) prior  to

installation.

6.  Apply Tooling (B) to the threads of bolts (1).

7.  Install bolts (1). Remove Tooling  (A). Install

remaining bolts (1).

Note: Do not use a torch to heat the ring gear.

8.  Use a suitable tool to prevent the flywheel from

rotating. Tighten bolts (1) to a torque of 300 N·m

(221 lb ft).

c.  Ensure that the orientation of ring gear (3) is

correct and quickly install the ring gear onto

flywheel (2).

9.  Remove the lifting device from flywheel (2).

2.  Inspect the crankshaft rear seal for leaks. If there

are any oil leaks, replace the crankshaft rear seal.

Refer to Disassembly and Assembly, “Crankshaft

Rear Seal - Remove”.

10. Check the runout of the  flywheel. Refer to

Systems Operations, Testing and  Adjusting,

“Flywheel - Inspect”.

1.  Ensure that the crankshaft flange and the housing

for the crankshaft rear seal is clean, dry and free

from damage. It is possible to reclaim a crankshaft

flange that has a worn seal surface, or a damaged

seal surface by installing a wear sleeve. Refer to

Disassembly and Assembly, “Crankshaft Wear

NOTICE

Keep all parts clean from contaminants.

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

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

plastic sleeve. Ensure that the plastic sleeve is

squarely installed within the crankshaft rear seal.

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.

Note: The plastic sleeve  is included in order to

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

the crankshaft flange.

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

crankshaft wear sleeve.

Note: Do not lubricate the crankshaft rear seal or

the crankshaft flange. The crankshaft rear seal

must be installed dry.

Note: Take care to avoid damaging the crankshaft.

3.  Align the plastic sleeve with the crankshaft flange.

Ensure that the plastic sleeve is engaged onto the

crankshaft flange. Push new crankshaft rear seal

(2) squarely onto the crankshaft flange.

2.  Insert a thin blade between the crankshaft wear

sleeve and the crankshaft below the scored line.

The crankshaft wear sleeve will separate along

the line.

During this process, the plastic  sleeve will be

forced out of the crankshaft rear seal. Discard the

plastic sleeve.

3.  Remove the crankshaft wear sleeve from the

crankshaft.

Installation Procedure

4.  Apply Tooling (A) to the threads of bolts (3). Install

bolts (1) and (3). Tighten the bolts to a torque of

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

is shown in Illustration 98.
