BLADE REMOVAL AND INSTALLATION FOR THE FOLLOWING  BLADES

EB16 blade (260-069)

 requires a 

G 5/8

 bushing and a 3/16” X 1 3/8” key.

BLADE REMOVAL PROCEDURES

1.

Remove the eight bolts holding the front gr place and remove the grill (Figure 4.1). 

2.

Remove the three bolts from blade. Remove the two bolts  from the bushing and hub. Put the
two bolts in the  threaded part of the bushing and turn evenly until bushing  separates from
hub. 

BLADE INSTALLATION PROCEDURES FOR DD16

1.

 Make sure that the shaft and key-way are clean and smooth before installing

the blade. 

2. Insert the cap screws through the clearance holes in the bushing and place
loosely into the hub of the blade.  Do not press the bushing in.  Hand start  

3.  Insert the cap screws, turning them just enough to  engage the threads in the
tapped holes on the hub.  The bushing should be loose in the hub.  Insert the 
key into the key-way (

Figure 4.9

).  Tighten two  bolts drawing the bushing and

hub together. 

4. Slide the blade onto the bushing/hub assembly and insert the three screws
through the blade and  turn evenly but do not tighten.  Make sure blade is  in
line with hub then tighten screws 

(Fig. 4.10)

.    Locate the blade and bushing so

that the blade tips  do not hit the rear grill eyelets. On some models  the blade
and bushing may be in beyond or out  away from the end of the shaft up to ¼”
but no  further.  This is necessary for proper blade  clearance. 

5.  Tighten the cap screws progressively with a  wrench. Tighten each cap screw partial turns  successively until
both are tight. Final tightening  should be done with torque wrench with the  torque set at 7.5 ft./lbs. for each
screw.  Over tightening will cause the cap screws to break or  crack the blade. (

Figure 4.10

)

Carefully turn the blade and check for clearance  between the blade and
shroud.  Confirm that the  blade is free to rotate without hitting other parts. 

Reinstall the front grill and test the blower. 

If you have any trouble removing or installing the  blade on your blower,
contact the factory for  assistance at 412-824-6944.
