To access and service the oil cooler, remove the top
mounting screw and loosen the two side screws, then
lift off the No. 2 side cylinder shroud. If required,
remove the two screws holding the oil cooler to the
blower housing. Pull the cooler away from the blower
housing. Clean both sides of the cooler with a brush as
shown in Figures 17 and 18, or with compressed air.
After cleaning, reattach the oil cooler to the lower
blower housing with the two mounting screws.

Air Cleaners
These engines use a heavy-duty style air cleaner (see
Figure 19) or a flat air cleaner (see Figure 23). These
systems are CARB/EPA certified and the components
should not be altered or modified in any way.
NOTE: Lift or move this engine using the lifting
strap and lifting point shown in Figure 1.
DO NOT lift the engine by the air cleaner.
Heavy-Duty Air Cleaner
The heavy-duty air cleaner consists of a cylindrical
housing mounted to the carburetor and intake
manifold. The housing contains a paper element and
inner element, designed for longer service intervals.
