-
If out of the standard, replace cylinder block (1) and main bearing caps as assembly.
NOTE:
Cylinder block cannot be replaced as a single part, because it is machined together with main bearing caps.
PISTON TO CYLINDER BORE CLEARANCE
Cylinder Bore inner Diameter
-
Using a bore gauge, measure cylinder bore for wear, out-of-round and taper at six different points on each cylinder. [(A) and (B) directions at (C),
(D) and (E)] is in longitudinal direction of engine.
-
If the measured value exceeds the limit, or if there are scratches and/or seizure on the cylinder inner wall, hone or re-bore the inner wall.
-
Oversize piston is provided. When using oversize piston, re-bore cylinder so that the clearance of the piston to cylinder bore satisfies the standard.
CAUTION:
When using oversize piston, use oversize pistons for all cylinders with oversize piston rings.
Oversize (O/S) : 0.2 mm (0.008 in)
Piston Skirt Diameter
Measure the outer diameter of piston skirt with a micrometer (A).
