Replacing Crankshaft Sleeve
1. Remove the used crankshaft sleeve.
2. Set the sleeve guide (2) to the crankshaft.
3. Heat a new sleeve to a temperature between 150 and 200 °C
(302 and 392 °F), and fix the sleeve to the crankshaft as shown
in figure.
4. Press fit the sleeve using the auxiliary socket for pushing (3).
• Mount the sleeve with its largely chamfered surface facing
outward.
• Should heating is not enough, a sleeve might stop halfway,
so careful.
