Typical example

1. Thoroughly clean the journal on the crankshaft (3) for the crankshaft gear (1) and the keyway slot for the key (2). Inspect the journal for the crankshaft gear (1), the keyway slot, and the key for wear or damage. If necessary, replace any damaged component.

2. Install the key (2) into the keyway slot in the crankshaft (3).

   Note: The crankshaft gear (1) may be a slip fit on the crankshaft (3).

3. Check if the crankshaft gear (1) is a slip fit on the crankshaft (3). If the crankshaft gear (1) is a slip fit on the crankshaft (3), proceed to Step 5.

   Note: Ensure that heat is applied to the crankshaft gear (1) only. Do not apply heat directly onto the crankshaft (3).

   Note: Ensure that suitable clothing is worn in order to handle the heated crankshaft gear.

4. If the crankshaft gear is not a slip fit on the crankshaft, heat the crankshaft gear in an oven to 200 °C (392 °F).

5. Ensure that the shoulder on the crankshaft gear (1) is installed toward the front of the crankshaft (3). Install the crankshaft gear (1) onto the crankshaft (3) and the key (2).
