Cylinder Bore Sleeve Removal
Note: Do not chill or heat the cylinder bore sleeve or the cylinder block when removing or installing a new cylinder bore sleeve. Chilling or heating the
cylinder bore sleeve or the cylinder block will cause engine damage and will not aid the removal or installation of the new cylinder bore sleeve.
Note: Do not damage the crankshaft connecting rod journals or reluctor ring or engine damage will occur.
1. If the crankshaft is still installed, rotate the crankshaft so that the counterweight is to the right side and the connecting rod journal is to the left side
and not in alignment with the cylinder bore.
2. Install the cylinder bore sleeve puller EN 45680-402 (1), which is part of EN 45680-400, through the cylinder bore.
Note: Ensure that the shoe is flat against the bottom of the cylinder bore sleeve or damage to the cylinder bore sleeve puller EN 45680402 will occur.
