1986 325 Blower Motor

My blower motor quit on me the other day and I had to replace it. Fortunately I have a couple of extra parts cars for this situation. Unfortunately I was unable to get the replacement blower motor in without damaging one of the squirrel cages. It's really tight, being directly behind the head and intake, and I suppose the plastic is brittle after 23 years. I found the breaks before I reassembled, and coated the breaks with JB Weld, but even after curing overnight the fan still broke and makes all kind of noise on anything besides level 1.
Considering this, I have two questions.
1. How do I get the blower motor in without breaking one of the fans? Do I need to drop a motor mount or both, so I can lower the engine about 3 inches?
2. Does anyone know how to remove the fan from the motor? It kind of looks like a press fit to me, and with this old, old plastic, I'm not hopeful of bruting it off without breaking the good one on my old motor.

Thanks,
Chris

silversled can only hope to improve
I just did this on my 1988 325iC....the key is to remove the valve cover to provide more room to get the damn squirrel cage in/out without toasting the plastic vains...sucks...I feel your pain...truth is I had to do the very same repair on my wifes 1990 MB 300TE. I swear to God, every single German car I have ever owned in my life, and there have been many, have had a crapped out heater blower motor..............Behr sucks....I have replaced 2 of these pieces of shit in the last 4 months, one BMW and one Mercedes Benz. Collectively they would have cost me a grand but fortunately I have an excellent junk yard near so it was only around 50 beans for both, but nevertheless....Behr sucks....

Pull the valve cover, huh? I had not thought of that. I will give that a try. Thanks.
Now, anyone know anything about replacing the squirrel cage fans on these buggers?

Thanks,
Chris
