[QUOTE=Scoutx;2010387]Note A.O. Smith has been bought out the new designation for this motor is the RAL1006.

Note this motor spins CCW from the end of the motor where the leads go into the case. I accidently mounted mine upside down since the extra of the case bolts stuck out the other side making it perfect for mounting to the base plate. So I would suggest that you either:
1) reverse the direction of the case bolts one at a time
2) remove the whole rotor assembly and flip it end for end and then do #1 during reassembly.

Since I had already cut the shaft lengths before I caught this option. #2 was my only choice.

You want the shaft that sticks up to spin CCW as you look down on the motor.

Replacing the lower fan blade wasn't a good option because it's an 11" six blade fan in mine and I can't find anyone that even makes an 11" fan blade anymore.

I'm in the process of repairing a '64 Overlander with a factory Bay Breeze A/C unit (Model TAC-10 serial #00037). The blower motor was the typical pile of rust.

Note both fans suck in at the bottom and blow out at the top.

I also decided to add a rain shield for the blower motor. The unit is a domed 7" disk of black plastic and simply press fits over the shaft and provides an 'umbrella' for the fan motor. As a side benefit it also assists in cooling the motor given the webs on the interior that act like a simple paddle fan helping to suck air through the motor.

I mounted the included bushing bracket to the bottom of the base plate which then allowed me put slide the OEM rubber seal over it so it can seal against the skin to prevent leaks. I also chalked the inside between the bracket and the motor to insure no water intrusion and to keep out pesky bugs.
