9-9. General.

a. There is little that can be done to repair a sprocket that has sustained damage.

However, if the hub is intact, there may be some things done that can make it

functional.

b. Usually, the sprocket must be replaced with a new or cannibalized item. The vehicle

cannot operate with either the inner or outer sprocket missing on a side, but it can

function with one or several non-consecutive teeth missing from the sprocket.

Operations should be limited to low-speed, gradual turns.
