REPLACING DRUM AND SPROCKET
WARWING!—Do not start engine without guide bar, chain, and bar clamp completely assembled. The clutch can come off without
the guide bar and chain completely assembled and serious injury could result.
1. Remove the cylinder cover and the high tension lead from
the spark plug to prevent accidental starting of the saw.
Figure 14.
2. Remove the bar clamp and the bar and chain. Figure 15.
3. Remove the clutch by using a hammer and punch. Position
the punch as shown in Figure 16 and tap lightly with the
hammer. The threads are LEFT HAND so a clockwise
rotation is necessary to remove.
Remove the clutch drum and sprocket and inspect for wear.
Replace if necessary. Inspect the clutch shoes and springs.
Replace any that are broken or worn. Figure 17. Replace
the clutch in a counterclockwise direction. Replace high
tension lead and cylinder cover.
Inspect the chain sprocket regularly for wear; a worn
sprocket will make the chain run erratically and will
shorten the life of the bar and chain. Figure 18.
