Ensure cylinder liners (2) protrude 0.003-0.006 in. (0.08-0.15 mm) above the engine block (1) whenthey are properly installed.NOTEShims are used to compensate for counterbore depth wear.Steps 15 through 17 check cylinder liner for proper protrusionwithout installing a cylinder liner.15. Measure cylinder liner (2) outside flange (4) with micrometer. Do not include bead (3) when takingmeasurements.16. Measure counterbore ledge (5) depth with gauge block. Ensure counterbore ledge (5) is smooth andnot “cupped” more than 0.0014 in. (.036 mm). Depth must not vary more than 0.001 in. (0.254 mm).17. Subtract counterbore depth from cylinder liner (2) outside flange (4) depth to determine amount ofshims or depth of counterbore cut to be made to obtain 0.0036-0.006 in. (0.08-0.15 mm) linerprotrusion.18. Install cylinder liner (2) and clamps in engine block (1) without O-rings or crevice seal. Ensureclamps are installed so there is equal pressure on liner. Tighten clamps 50 lb-ft (68 N•m).19. Use feeler gauge to check clearance between lower liner (2) and engine block (1). If clearance is notwithin limits specified in table 5-5, check lower O-ring groove inside diameter in engine block (1).20. Remove cylinder liner (2) from engine block (1).21. Use telescoping gauge to check lower liner bore (6) in engine block (1). Bore (6) should be withinlimits set in table 5-5.Table 5-5.
