cylinder sleeves (1) only.
(1)
Inspect each cylinder sleeve (1):
(a) A smooth, shiny surface between upper and lower limits of ring travel
indicates normal wear; cylinder sleeve may be reused.
(b) A smooth, shiny surface complete length of cylinder sleeve (1) indicates
a worn out sleeve due to normal wear and should be replaced.
(c) Heavy vertical lines fringed by a discolored band caused by metal trans-
ferring from one spot to another indicates scuffed cylinder sleeve
walls. Scuffing may be in one particular area or it may occur the entire
length of piston travel. If this condition exists, replace cylinder
sleeve.
(d) Excessive wear and a hazy, dull, or mat finish in cylinder sleeve piston
ring travel area indicates a dusting failure. Replace cylinder sleeve.
