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, seals, and O-Rings.
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 and crankcase to be certain that
all of the old RTV has been removed. Use gasket
remover, lacquer thinner, or paint remover to remove
any remaining traces.
Typical Reassembly Sequence
The following sequence is suggested for complete
engine reassembly. This procedure assumes that all
components are new or have been reconditioned, and
all component subassembly work has been completed.
The sequence may vary to accommodate options or
special equipment. Detailed procedures can be found
in subsequent subsections.
1. Install flywheel end oil seal and camshaft seal.
2. Install crankshaft.
3. Install connecting rods with pistons and rings.
4. Install governor cross shaft.
5. Install camshaft.
6. Install oil seal in oil pan.
7. Install oil pan assembly.
8. Install cylinder studs.
9. Install hydraulic lifters.
10. Install cylinder heads and set valve lash.
11. Install breather cover.
12. Install oil fill/dipstick tube and lower blower
housing.
13. Install intake manifold and coolant by-pass
hose with wiring harness.
14. Install water pump, drive belt and transfer tube.
15. Install stator and rectifier-regulator.
16. Install radiators, cooling system and hoses.
17. Install electric starter.
18. Install ignition modules and flywheel.
19. Install spark plugs.
20. Install overflow reservoir.
21. Install blocking plates and fan.
22. Install valve covers.
23. Install carburetor.
24. Install external governor controls.

27. Install air cleaner base.
28. Install muffler.
29. Install oil filter.
30. Fill with oil.
31. Fill cooling system.
32. Reconnect battery and spark plug leads.
Install Flywheel End Oil Seal and
Camshaft Seal
1. Check to make sure that there are no nicks or
burrs in the crankshaft and camshaft seal bores
of the crankcase.
2. Apply a light coat of engine oil to the outside
diameter of the oil seal.
3. Install the oil seals into the crankcase using
a seal driver. Make sure the oil seals are installed
straight and true in their respective bores.
The crankshaft seal should be installed so that
the tool bottoms against the crankcase. See
Figure 11-1.
