Powerhead Inspection
Use
Gel Seal and Gasket Remover
to remove all
traces of gaskets, adhesives, and
Gel-Seal II™
sealant from the cylinder block and crankcase.
Carefully remove any carbon accumulation from
the tops and ring grooves of the piston using
Engine Tuner
. A ring groove cleaning tool can be
made by breaking an old ring and grinding an
angle on its end. Do not damage ring grooves
while cleaning.
Thoroughly wash entire cylinder block and crank-
case with warm, soapy water to remove all traces
of contaminants.
Air dry cylinder block and crankcase. Blow all
holes and passageways with compressed air.
Cover the cylinder walls with a liberal amount of
outboard lubricant to prevent corrosion.
Powerhead Inspection
IMPORTANT:
Before any inspection process
can begin, all internal components must be com-
pletely clean and free of contaminants.
Visually inspect all parts. Check for unusual wear
patterns, scuffing, or deterioration of aluminum
parts, heat-related discoloration of bearings and
bearing surfaces, and broken components.
Cylinder Head
Check for cylinder head warpage using a piece of
bar stock or machinist’s straightedge and a feeler
gauge set.
Cylinder head warpage must not exceed 0.003 in.
(0.08 mm) per inch of measurement. Replace
head if warpage exceeds this dimension.
