INSTALLATION

NOTE

Ensure blower to cylinder block bolts are loose before installing blower drive support.

Install blower drive support assembly to engine as follows:

Using gasket adhesive, affix new gasket (Figure 6, Item 13) to blower drive support assembly

(Figure 6, Item 11).

Place high speed governor weights (Figure 5, Item 29) in horizontal position to provide clearance.

Position operating shaft fork (Figure 6, Item 2) away from blower for additional clearance.

Insert blower drive assembly (Figure 6, Item 11) in flywheel housing (Figure 6, Item 1) until drive gear

(Figure 6, Item 17) enters housing. Turn drive assembly until serrated end of weight shaft

(Figure 6, Item 12) passes around operating fork (Figure 6, Item 2) and fork is between serrated end of

shaft and riser bearing (Figure 6, Item 30).

Push blower drive support assembly (Figure 6, Item 11) up against flywheel housing. Mesh serrated

end of weight shaft (Figure 6, Item 12) with governor drive plate, and mesh blower drive gear

(Figure 6, Item 17) with camshaft gear.

Install two new copper flat washers (Figure 6, Item 3) and two screws (Figure 6, Item 4) on small end of

blower drive support assembly (Figure 6, Item 11) into flywheel housing. Torque bolts to 20–24 lb-ft

(27–33 N·m).

Insert blower drive shaft (Figure 6, Item 10) into blower gear shaft (Figure 6, Item 18). If necessary, rotate

camshaft until serrations on blower drive shaft align with serrations in blower drive cam and blower drive

gear shaft.

Install retaining ring (Figure 6, Item 9) into blower drive gear shaft (Figure 6, Item 18).

Install new gasket (Figure 6, Item 8), cover (Figure 6, Item 7), four flat washers (Figure 6, Item 5), and four

screws (Figure 6, Item 6) on blower drive support assembly (Figure 6, Item 11). Torque screws

to 20–24 lb-ft (27–33 N·m).
