wrench.
 Remove the clutch cover.
 Remove the bar and chain from the mounting

as shown.
 Position the chain so there is a loop at the back
of the bar.

the loop around the sprocket.
 Fit the bar flush against the mounting surface
so that the bar studs are in the long slot of the
bar.

adjusting pin in the clutch cover is in the bar
tensioning pin hole and that both bar studs are
in their respective holes in the clutch cover.
