Bore Reconditioning

1. Measure the cylinder bore for out-of-round and taper.
^ 0.05 mm (0.002 inch) Max.
2. If the cylinder bore taper or the wear exceed specification, bore and hone the cylinders to the smallest oversize.
^ 101.618-101.643 mm (4.0007-4.0017 inch) Max.
3. Fine vertical scratches made by the ring ends will not, by themselves, cause excessive oil consumption. Honing to remove the scratches is unnecessary.
4. If the bore is glazed but otherwise serviceable, break the glaze lightly with a hone and replace the piston rings.
5. If honing is not required, the cylinder bores should be cleaned with a hot water and detergent wash. Apply clean engine oil to the bore after cleaning.
