If the air cleaner base requires removal, proceed as
follows:
1. Remove the mounting screws for the fuel pump
(if equipped), and the blower housing.
2. Raise or remove the blower housing for access to
the air cleaner base.
3. Remove the air cleaner components from the
base. See Figure 4-3.
4. Remove the two hex flange nuts securing the air
cleaner base onto the mounting studs.
5. Disconnect the breather hose from the air cleaner
base, then remove the base and gasket.
6. Reverse procedure to reassemble components.
Torque the two hex flange nuts to 6.2-7.3 N·m
(55-65 in. lb.). Torque the blower housing screws
to 4.0 N·m (35 in. lb.), and the two front HI-LO
screws to 2.8 N·m (25 in. lb.).
To ensure proper cooling, make sure the grass screen,
cooling fan fins, and other external surfaces of the
engine are kept clean at all times.
Annually or every 100 hours of operation (more often
under extremely dusty or dirty conditions), remove
the blower housing and other cooling shrouds. Clean
the cooling fins and external surfaces as necessary.
Make sure the cooling shrouds are reinstalled.
NOTE: Operating the engine with a blocked grass
screen, dirty or plugged cooling fins, and/or
cooling shrouds removed, will cause engine
damage due to overheating.
