Reassembly
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 pre-applied.
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 oil pan, 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.
Typical Reassembly Sequence
The following sequence is suggested for complete
engine reassembly. This procedure assumes that all

20. Install carburetor.
21. Install external governor controls.
22. Install throttle and choke controls.
23. Install electric starter motor.
24. Install fuel pump.
25. Install air cleaner assembly (see Section 4).
26. Install muffler.
27. Install oil cooler.
28. Install oil filter and fill crankcase with oil.

Install Flywheel End Oil Seal
1. Make sure that the seal bore of the crankcase is
clean and free of any nicks or burrs. See Figure
11-1.
Figure 11-1. Seal Bore of Crankcase.
2. Apply a light coat of engine oil to the outside
diameter of the oil seal.
3. Drive the oil seal into the crankcase using a seal
driver. Make sure the oil seal is installed straight
and true in the bore and the tool bottoms against
the crankcase. See Figure 11-2.
