>>A<< Crankshaft Sprocket Installation

WARNING: This page is about a different car, the 2012 Mitsubishi Lancer. However, it is still accessible from the selected car via links, so may be relevant.

Wipe off the dirt on the crankshaft sprocket and crankshaft as shown in the illustration using a rag, and then degrease them.
NOTE: Degrease them to prevent drop in the friction coefficient of the pressed area, which is caused by oil adhesion.
Install the crankshaft sprocket to the crankshaft.
