6.4 New Liner Feed-rates

The liner was changed on cylinder 4, with the results again showing textbook bedding-in curve. During
this bedding in period, the effect of reducing the cylinder lubricant by 10% was demonstrated. As
expected it increased the wear on the liner and showed how sensitive the sensors/cylinders are to
changes during this bedding in period.
