NOTE: Make sure engine is assembled using all
specifi ed torque values, tightening 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
®
is
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 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.

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.
Install Governor Cross Shaft
1. Lubricate governor cross shaft bearing surfaces in
crankcase with engine oil.
2. Slide small lower washer onto governor cross shaft
and install cross shaft from inside of crankcase.
3. 6 mm governor shaft: Install plain washer and then
insert hitch pin into smaller, lower hole of governor
cross shaft.
8 mm governor shaft: Install nylon washer onto
governor cross shaft, then start push-on retaining
ring. Hold cross shaft up in position, place a
0.50 mm (0.020 in.) feeler gauge on top of nylon
washer, and push retaining ring down shaft to
secure. Remove feeler gauge, which will have
established proper end play.
