VISUALLY INSPECT CYLINDER LINERS

IMPORTANT: If liner pitting has occurred, check
condition of coolant.
NOTE: When installing reusable liners, rotate 90 from
original position. The liners should be deglazed
and ring sets installed in pistons.
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).
Depth of erosion is one-half or more of the packing
step (D).
