REPLACING SLOTTED GEAR
•  If the axle, slotted gear and sprocket assembly is 

disassembled, mark down the positions of the parts 
as they are removed. The drive wheel and sprocket 
positions in relation to the slotted gear determine 
which direction the spreader plate will spin. Be sure to 
reassemble them in their original positions. (Refer to 
figure 4 on page 6.) Use shim washers (Ref. no. 21 on 
pages 14 and 15) as needed for minimum backlash.  
Add grease to gear and sprocket.

REPLACING AGITATOR
•  If the agitator hairpin becomes damaged or worn it 

can be replaced. See figure 19.

LOCKED UP SPREADER
•  Turn the spreader over so that the wheels are off the 

ground.

• 

Loosen all three nuts on the shaft support plate just 
enough so that the bolts can be turned easily with a 
wrench but cannot be turned by hand.

• 

Spin the drive wheel and note how freely it spins and 
how much noise the slotted gear makes.

• 

To free up the wheel and gear, tap gently on the front 
or rear edge of the shaft support plate to move it 
slightly forward or backward. You can also tap at the 
corners of the plate to angle it slightly.

• 

Spin the drive wheel after each adjustment to see if it 
spins more freely and if the gear noise is reduced.

• 

Continue making slight adjustments until you find the 
position where the drive wheel spins most freely and 
the gear makes the least noise.

•  Secure the shaft support plate in this position by 

retightening all three nuts that you loosened.
