CYLINDER HEAD ASSEMBLY/INSPECT/REPLACE (CONT).
Remove 12 capscrews and washers from each cylinder head.
Because the cylinder head assembly weighs more than 50 lbs (23 kg), two people or a
hoist will be required to lift the cylinder heads to avoid personal injury.
To prevent damage to the head gasket surface, put the cylinder heads on wooden blocks
when they are removed.
To prevent increased wear, mark each cylinder head as it is removed so it can be installed back in
its original location.
Lift cylinder heads from block and remove cylinder head gaskets.
Dry cleaning solvent is potentially dangerous. Avoid repeated and prolonged breathing of
vapors and skin contact with the liquid. Do not use near open flame, arcing equipment, or
other ignition source. Always wear eye protection and protective clothing.
Live steam used for cleaning shall not exceed 100 psi (690 kPa). During steam cleaning
operations, adequate ventilation, natural or forced, should be provided. Do not direct live
steam against skin.
Death or serious injury could occur if compressed air is directed against the skin. Do not
use compressed air for cleaning or drying unless the pressure is/has been reduced to 30
psi (2.11 kgcm2) or less. When working with compressed air always use chip guards, eye
protection, and other personal protective equipment.
Clean and inspect cylinder block as follows:
Place a clean, lint-free rag in each push rod cavity in cylinder block
Use gasket scraper to remove heavy dirt and debris from head gasket surface of cylinder block.
Use razor blade scraper and solvent to remove any remaining material from cylinder block surface.
Clean with dry cleaning solvent and dry with compressed air.
Remove the rag after the cylinder block is cleaned.
