Hello, I have a BL2660 snow blower and my main stage auger is not centered / is causing the chain to bind. Does anyone have an exploded view of the blower, unfortunately I do not have a service manual for this attachment. There is a collar with 2 set screws on the far left side of the main stage, even when I removed the set screws, I could not get the main auger to move over and re-align the gear with the chain.

Any pictures or suggestions would help. I do not want to continue to run the unit since it puts a lot of stress on chain.
