Cylinder Block, Liners, Pistons, and Rods
VISUALLY INSPECT CYLINDER LINERS
IMPORTANT: If liner pitting has occurred, check
condition of coolant.
1. Inspect exterior length of liner for pitting (A). Check
packing step for erosion (B). If pitting or erosion is
observed, measure depth of pits with a fine wire or
needle. Replace piston and liner if:
Depth of any pit is one-half or more of liner
thickness (C) or more.
Depth of erosion is one-half or more of the packing
step (D) or more.
Cylinder Liner--Specification
Thickness............................................. 6.05--6.15 mm (0.238--0.242 in.)
Packing Step Dimension ..................... 1.45--1.55 mm (0.057--0.061 in.)
NOTE: Liners are reusable if the depth of pits or erosion
is less than one-half the amount specified. When
installing reusable liners, rotate 90 from original
position. The liners should be also deglazed and
new ring sets installed in pistons.
