Cylinder inspection
1. Clean and inspect the cylinder, inside and out.
NOTE: If there is any sign of damage, especially
cracked cooling fins, short block the engine.
NOTE: Take two measurements of the cylinder bore
90 degrees apart at the top, bottom and mid-
dle of the cylinder. See Figure 10.17.
NOTE: The measurements can be made using tele-
scoping gauges, inside micrometers or a cyl-
inder bore dial indicator. See Figure 10.18.
2. Compare the measurements to those that are listed
in the chart at the end of the chapter.
3. Inspect the cylinder.
NOTE: The cylinder is manufactured using a special
machining process. This process does not
leave a cross hatch that is normally seen in
most engines. As the engine breaks in, the
cylinder will develop a smooth, dull finish.
See Figure 10.19.
NOTE: The cylinder may have some scratches. As
long as the scratches cannot be felt with a
finger nail, they are acceptable.
NOTE: If the cylinder needs to be de-glazed,
replace the cylinder block.
