Don't bother. No offense to the earlier poster, but reducing the fan/housing gap does nothing, with the 2nd order exception of making the fan blades slightly longer. Any fan/housing gap packs in with snow almost instantly, so the actual fan/housing gap is generally zero or close to it at all times. Improving blower performance by minimizing of this gap is a popular myth.
You have to prep to run a blower. Clean up your driveway and throw the sticks and big stones out of the way BEFORE the snow flys - that's how you avoid breaking shear pins.
Your B2789 is a 540 PTO blower, so relative speed should be OK. Are you sure your BX is actually running at proper full-blast PTO speed? Even a little less RPMs makes a significant difference. Also, if you really pack up the blower, it will reduce the throw substantially. With all of the snow we've been having the last few weeks, it is possible that you are simply driving too fast to keep the blower clearing itself out. Try going a little slower and see if it makes a difference.
Fan blade gap is not a myth. The longer your blades are, the faster the tip speed is which equals more blowing power. As far as the housing packing with snow to fill the gap, that is exactly what you DO NOT WANT. That packed snow creates more friction which reduces blowing power. Packed snow has much more friction than smooth metal. Performance of a blower can be improved greatly by having the blower fan set up properly.
