Cylinder Bore Taper




Cylinder Bore Taper

NOTE: Refer to the Engine System Level for the specification.

1. Measure the cylinder bore at the top, middle and bottom of piston ring travel in 2 directions as indicated. Verify the cylinder bore is within the wear limit. The difference indicates the cylinder bore taper. If the cylinder bore taper does not meet specification, bore the cylinder to the next oversize limit.
