Typical example
If the ring gear was removed, follow Steps 1.a through 1.c in order to install ring gear (3) to flywheel (2).
Identify the orientation of the new ring gear in order to install the ring gear correctly onto the flywheel. Note: The chamfered side of gear teeth (Y) must face toward the starting motor when the flywheel is installed. This will ensure the correct engagement of the starting motor.
Heat ring gear (3) in an oven to a maximum temperature of 150°C (302°F) prior to installation. Note: Do not use a torch to heat the ring gear.
Ensure that the orientation of ring gear (3) is correct and quickly install the ring gear onto flywheel (2).

Typical example
Thoroughly clean the flywheel housing. 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 and Install".
Install Tooling (B) to positions (X) in the crankshaft.
Install Tooling (A) and a suitable lifting device to flywheel (2). The weight of the flywheel is approximately 42 kg (93 lb).
Position flywheel (2) onto Tooling (B). On three cylinder engines that have a roll pin, ensure that the roll pin is installed to the crankshaft and that the roll pin is free from damage. Align the hole in the flywheel with the roll pin in the crankshaft.
Install bolts (1) finger tight.
Remove Tooling (B) and install the two remaining bolts (1).
Use a suitable tool to prevent flywheel (2) from rotating. Tighten bolts (1) to a torque of 74 N m (54 lb ft).
Remove Tooling (A) and the lifting device from the flywheel. End By:
Install the electric starting motor. Refer to Disassembly and Assembly, "Electric Starting Motor - Remove and Install".
