Engine – mechanical (V6)Cylinder liners
- Inspect the flywheel ring gear and, if necessary, replace it as follows:
- remove the old ring gear using a hydraulic press.
- thoroughly clean the mating surfaces of the new ring gear and of the flywheel.
- uniformly pre-heat the new ring gear to 120 to 140°C and fit it to the engine flywheel.
- leave the parts to cool to ambient temperature: do not force the cooling of the parts.
CYLINDER LINERS
- Check the class of the cylinder liners.
NOTE: Cylinder liners are selected according to their inner diameter and are divided into three categories - A, B and C. These categories are identified by BLUE, PINK AND GREEN dots located on the outer surface.
- Using a reamer applied to a centesimal dial gauge, measure the inner diameter of the cylinder liners.
- Check that the inner diameter, taper and ovalization of the cylinder liners are within the prescribed limits.
