NOTE: Make sure engine is assembled using all
specied torque values, tightening sequences
and clearances. Failure to observe specications
could cause severe engine wear or damage.
Always use new gaskets. Apply a small amount
of oil to threads of critical fasteners before
assembly, unless a sealant or Loctite
®
is
specied or preapplied.
Make sure all traces of any cleaner are removed before
engine is assembled and placed into operation. Even
small amounts of these cleaners can quickly break down
lubricating properties of engine oil.
Check closure plate, crankcase, cylinder heads, and
valve covers to be certain all old sealing material has
been removed. Use gasket remover, lacquer thinner, or
paint remover to remove any remaining traces. Clean
surfaces with isopropyl alcohol, acetone, lacquer thinner,
or electrical contact cleaner.
Install Flywheel End Oil Seal
1. Make sure seal bore of crankcase is clean and free
of any nicks or burrs.
2. Apply a light coat of clean engine oil to outside
diameter of oil seal.
3. Drive oil seal into crankcase using a seal driver.
Make sure oil seal is installed straight and true in
bore and tool bottoms against crankcase.
