NOTE: Make sure engine is assembled using all
specifi ed torque values, torque sequences, and
clearances. Failure to observe specifi 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
specifi 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 oil pan, crankcase, cylinder heads, and valve
covers to be certain all old gasket 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.

2. Slide lower washer onto governor cross shaft and
install cross shaft from inside of crankcase.

on top of nylon washer, and push retaining ring
down shaft to secure. Remove feeler gauge, which
