CLEANING AND INSPECTION

WARNING

Solvent cleaning compound MIL-PRF-680 Type III is an environmentally compliant and low toxic mate-

rial. However, it may be irritating to the eyes and skin. Use protective gloves and goggles. Use in well-venti-

lated areas. Keep away from open flames and other sources of ignition.

CAUTION

Both surfaces of spacer plate, bottom surface of cylinder head, and top of cylinder block MUST be clean

and dry. Do not use hard gasket scrapers or files to remove gasket material, grease or other particles from

cylinder head, block or spacer plate surfaces. These tools could cause nicks or scratches which, in turn,

could cause leaks or incorrect seat between cylinder head and spacer plate, and/or block and spacer plate.

NOTE

Refer to WP 0176 00 for additional cleaning and inspection instructions.

Thoroughly clean cylinder head with solvent cleaning compound or other approved method of carbon removal.

Thoroughly clean both surfaces of spacer plate using solvent cleaning compound.

Visually inspect cylinder head and spacer plate for cracks, heat deterioration or other damage. Replace damaged cylin-

der head and/or spacer plate.

Check cylinder head for warpage using a straightedge and feeler gage. Replace warped cylinder head.

Inspect cylinder head valves for damage. If damaged, notify your supervisor.

block, cylinder head, spacer plate and all gaskets are clean and dry before installation.
