16.3 INSPECTION OF CYLINDER LINER

Inspect as follows:

1. Inspect the cylinder liner.

[a] Check the cylinder liner for cracks or scoring. If cracks or scoring are present,

replace t he liner.

NOTICE:

Cavitation is due to p oor cooling system maintenance. If

uncorrected, it will eventually make holes through the liner. This

can result in combu stion gases blowing wate r out of the radiator,

oil in the coolant, o r when the engine is stop ped will allow water

to ﬂow into the cylinder and result in major engin e damage due

to water in the oil or hydraulic lockup.

[b] Check the cylinder liner for cavitation. If indication of cavitation is present, replace

the liner.

[c] Check for bore polishing; if detected, replace the cylinder liner.

2. Inspect the outside diameter of the liner.

[a] Check the liner for fretting.

[b] If any fretting is found, remove it from the surface of the liner with a course, ﬂat stone.

3. Inspect the liner ﬂange in two steps:

[a] Inspect the top surface of compression seal for cracks, smoothness and ﬂatness.

[b] Inspect the balcony (bottom stop).
