Tropic Air ® External Blower Assembly, Removed from it's mount. New blower motor...
This externally mounted Tropic-Air ® blower assembly needs the new motor shown on the right.  It's a 2.0 Hp, 230 Volt model.  (To purchase this motor, click here .)
Removing the top of the blower assembly Top Removed...
In order to disassemble this kind of blower, the screws that are holding on the top, (located underneath the edge), must be removed.  These are usually phillips head or 5/16" hex screws.  Note the rust that has accumulated around the old motor housing (right).
At this point, we have to remove the foam insulation surrounding the motor itself.  The foam usually serves two purposes... 1, to reduce the noise emanating from the blower housing, and 2, to prevent bugs and other debris from being sucked into the blower air impeller. 

Normally it will work fine without this insulation, but if you can, try to preserve and re-install it.

CAREFULLY remove the foam insulation!
removing the housing retaining screws and carefully prying apart the mid section
With the foam removed, now it's time to remove the motor and retaining mount from the main housing.  This requires a 5/16" nut driver as shown on the left.  Usually there will be 4 screws on the bottom of the blower holding it in.   To finish separating the blower motor frame from the housing, I use a flat-headed screwdriver to pry the assembly apart.
pulling the assembly apart.  
Once a little bit of force is applied to the housing, it usually separates quite easily. 
Removing the grounding screw... (Save it!) ...now remove the motor ring retainer screws...
With the blower motor mounting frame detached from the rest of the housing, the first thing to do is to remove the green ground wire attached to the motor frame itself.  Then, remove the four screws holding the plastic motor mounting ring,  (right), using a 5/16" nut driver.
Maneuver the motor out of the mounting..  
Now we can remove the blower motor.  Because of size constraints, the brush assemblies must be hand maneuvered through the small hole.
