Cylinder Bore Cleaning and Inspection

CLEANING
1. After any cylinder bore service operation, such as honing or Reglazing, clean bores with soap or detergent and water.

CAUTION: If these procedures are not followed, rusting of the cylinder bores may occur.

2. Thoroughly rinse the bores with clean water to remove the soap or detergent, and wipe the bores dry with a clean, lint-free cloth.
3. Wipe the bores with a clean cloth dipped in clean engine oil Motorcraft meeting Ford specification WSS-M2C153-F.

INSPECTION
After the cylinder blocks (6010) has been thoroughly cleaned, check it for cracks. Invisible cracks may be detected by coating the suspected area with a mixture of 25 percent kerosene and 75 percent light engine oil. Wipe the part dry and immediately apply a coating of zinc oxide dissolved in wood alcohol. Do not use rubbing alcohol as a substitute. If cracks are present, the coating will become discolored at the damaged area. Replace the cylinder blocks if it is cracked.

CYLINDER BORE
Measure the bore with a bore gauge following the instructions of the manufacturer.





CYLINDER BORE TAPER
Measure the cylinder bores at points A and C as shown.

If the difference between measurements A and C exceeds the maximum taper value, rebore the cylinder to oversize.





CYLINDER OUT-OF-ROUND
Measure the cylinder bores in the directions as shown. If the difference between measurements exceeds the maximum out-of-round value, rebore the cylinder to oversize.

CYLINDER BORE DIAMETER
Measure the diameter of each cylinder bore at 32 mm (1.25 inch) down from head deck at 90 degrees to the piston pin centerline.
