Replace Rotary Broom Gearbox
Rotary Broom Drive Chain
The drive chain should be replaced if, when adjusted
properly, it can be pulled away from the front of the drive
sprocket more than 1/2 the height of a tooth on the
sprocket. Running the rotary broom with a worn chain
increases wear on the sprockets.
1. Remove the chain guard. Refer to LUBRICATION
of Rotary Broom Drive Chain in the Lubrication
Section.
2. Loosen the bearing flange mounting nuts and
bolts. Position the chain tension block so that the
chain has as much slack as possible. Tighten the
bearing flange mounting nuts and bolts slightly to
hold the bearing flange in this position.
