STEEL HOPPER SPREADERS – GAS – ELECTRIC CLUTCH
REMOVING & INSTALLING ELECTRIC CLUTCH
Tools Needed:
• Three-jaw gear puller
• Torch for heating/cutting
Removing Clutch
1. Disconnect battery power from spreader.
2. Disconnect spark plug wire and isolate from
spark plug.
3. Disconnect the clutch power and ground wires.
4. Loosen the two set screws of the 16-tooth
sprocket that runs the spinner. Remove the
sprocket (puller may be required).
5. Remove the #40 chain from the engine
sprocket to the clutch sprocket by loosening
the four bolts that hold the engine base and
sliding it toward the clutch assembly.
6. Remove the three 5/16"-18 x 3/4" cap screws
and lock washers that hold the 52-tooth clutch
sprocket in place.
7. Remove the two 1/4" x 1-1/4" cap screws that
anchor the torque tab of the clutch.
8. Remove the rotor part of the clutch assembly, then
remove the armature (puller may be required).
Installing Electric Clutch
1. Before installing the clutch, inspect all parts
that are to be reused for wear and/or damage.
Replace worn or damaged parts as needed.
2. Make sure that the input shaft of the gear box is
free of any nicks, burrs, rust, and corrosion that
may prevent the clutch assembly from sliding
onto the shaft. Clean and/or
fi le as needed.
3. Install the key, making sure that it is in the
correct location and is not too high for the
bearing race. Some races are not the same
depth and may have a step.
4. Apply an anti-seize coating to the gear box
input shaft. Line up the keyway and slide the
armature assembly down the shaft until it is
fully seated on the step of the input shaft.
5. Reapply the anti-seize coating to the gear box
input shaft. Line up the keyway and slide the
stator down until the bearing inner race bottoms
out against the armature assembly. There will
be a slight air gap between the two parts.
6. Anchor the torque tab using two 1/4" x 1-1/4" cap
screws.
NOTE: Use bolts that have a shoulder that will
NOT allow you to fully tighten the bolts. Not
allowing the torque tab to
fl oat will cause the
fi eld bearing to fail.
7. Connect the power and ground wires to the clutch.
8. Install the 52-tooth clutch mounted sprocket
using three 5/16"-18 x 3/4" cap screws and lock
washers.
9. Adjust the 12-tooth engine mounted drive
sprocket up or down so that it is level with the
52-tooth sprocket.
