Kohler Courage SV710-740 Service Manual page 121

NOTE: Make sure the engine is assembled using
all specified torque values, tightening
sequences, and clearances. Failure to observe
specifications could cause severe engine wear
or damage. Always use new gaskets.
Make sure all traces of any cleaner are removed before
the engine is assembled and placed into operation.
Even small amounts of these cleaners can quickly
break down the lubricating properties of engine oil.
Check the oil pan, crankcase, cylinder heads, and
valve covers to be certain that all old sealing material
has been removed. Use gasket remover, lacquer
thinner, or paint remover to remove any remaining
traces. Clean the surfaces with isopropyl alcohol,
acetone, lacquer thinner, or electrical contact cleaner.
