Kohler LH630-775 Service Manual page 143

General
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. Apply a
small amount of oil to the threads of critical
fasteners before assembly, unless a Sealant or
®
Loctite is specified or preapplied.
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 closure plate, 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.
