Heater Blower Motor, How to remove it for replacement Options

[sburns1967]

I have a 1973 914/4 2.0 which is is partially disassembled.

It came with two hot air blowers:

Single Port - Working Motor
Dual Port - Dead Motor

In 1973 there was apparently a switch between the dual outlet blower to a single outlet with a Y pipe.

I was thinking I would like to use the dual outlet one so I thought I would swap in the working motor.

Two questions:

1) Does the dual outlet unit provide better heat flow through the heat exchangers than the single outlet with a Y connector? Any pointers to pictures of each type mounted/hoses?

2) How to remove the motor:

Removed the 6 screws on the motor flange
Removed the nut/washer from the cage fan

After doing so I can get zero movement from the motor from the housing. Even prying between the flange and the housing nothing moves.

Does anyone know if there is some kind of adhesive between the motor flange and the housing? If so do I apply a little heat maybe?

Thanks in advance

If you have good heat exchangers, there will be enough heat coming into the cabin with the single outlet blower.

I added the Y pipe and hose to the passenger side, but rarely pulled the lever far enough to activate the blower. ( it only comes on at about 3/4 to full on the lever) didn't really like the looks and additional clutter of the hose going to the passenger side. So i removed it and capped that side. As it came originally.

I get plenty of heat as it is.
