SECTION 7: COVERS AND SHROUDS
GENERAL
In the course of tearing down a complete engine for ser-
vice and repairs, the engine shrouds and covers may need to
be removed. The following section briefly describes the order
in which these items should be removed.
1. Remove air cleaner assembly and carburetor as described
in Section 2, “AIR CLEANERS AND CARBURETION.”
2. Remove the nine capscrews from the BLOWER HOUSING
ASSEMBLY (see Figure 7.1).
Carefully remove the blower cover, making sure not to
stretch the wires from the RUN/STOP switch and low oil indi-
cator (LOS). When the cover is far enough away from the
engine, these wires may be unplugged.
3. Remove the capscrew from the LOWER SHROUD (see
Figure 7.1).
4. Remove the remaining capscrew from the UPPER SHROUD
(see Figure 7.1).
NOTE: The blower cover is notched at the point where
the governor rod and anti-lash spring pass through it.
This allows the cover to be removed without discon-
necting the governor rod from the governor arm.
NOTE: It will be helpful to make note of the locations
of the screws that hold the covers in place.
INSTALLATION OF COVERS AND SHROUDS:
To reinstall the covers and shrouds, reverse the previous
steps. Make sure that the wires for the RUN/STOP switch and
low oil indicator (LOS) are not in the way of the covers during
reassembly.
