Reassembly
88 19 690 01 Rev. -- KohlerEngines.com
NOTE: Make sure engine is assembled using all
speci fi ed torque values, torque sequences, and
clearances. Failure to observe speci fi 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 fi 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.
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. Install 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 (Mechanical Governor)
1. Lubricate governor cross shaft bearing surfaces in
crankcase with engine oil.
2. Slide lower washer onto governor cross shaft and
install cross shaft from inside of crankcase.
3. Install nylon washer onto governor cross shaft, then
start push-on retaining ring. Hold cross shaft up in
position, place a 0.50 mm (0.0020 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.
