•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.

•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.
