■ Removal

Refer to the figure 1.

NOTICE:

If you can feel a ridge of metal or hard carbon around the top of each cylinder, remove it with a ridge reamer (a). Follow the reamer manufacturer's instructions. If the ridge is not removed, it may damage the piston as it is pushed out. (Figure 2)
Take care not to damage the cylinder with the connecting rod.
Mark each piston/connecting rod assembly with its cylinder number to make sure they are reinstalled in the original order.
Keep all connecting rod bearings in order.

NOTE:

The existing number on the connecting rod does not indicate its position in the engine, it indicates the rod bore size.
