Fan cage/sqirrel cage tragedy

[Dibbons]

It's another one step forward/two steps back today in Mopar Land. Pulled the plastic squirrel cage off the heater motor blower during my heater box rebuild. It was stuck a little, so used some WD-40. Well, it finally came off but tiny bits and pieces of the plastic center hub went flying. It seems the plastic hub was old/hard/brittle and could not withstand my noble efforts. The sad thing is the blades were just fine and I could have left it alone (to fail at a later date?).

A quick internet search found nothing with respect to the squirrel cage itself (measures 5 1/2 inches in diamater and either 2 7/8 or 2 15/16 inches tall). Did not find anything new or used that seemed to match a complete blower motor with squirrel cage either. What does everyone else do in a case like this (heater delete, HaHa)? Thank you.

This one is not correct or your year but may work?

Looks like the one on Ebay has the fins reversed and/or is mounted reverse from mine, which I believe means it has an opposite rotation motor compared to mine. Might just epoxy the shaft and squirrel cage together and hope for the best.

If I were you, I'd take it to an HVAC supply house like Graingers, United refrigeration, etc. it's just a hamster wheel, anything with a blower has one just like it.

Related, and my apologies to the OP, mine runs quiet and smooth at all speeds. When diverting to dash for defrost, there is a rhythmic thump like a rubber mallet being smacked on the dash pad. Flow changes, but thump is too loud to allow to continue. Advice?

Dibbons is yours A/C or non-a/c/? I might have one.

Mine was broken as well on my 74 RR non AC box. From what I could find the AC blower motor runs the opposite direction from a non AC motor. I came up with a universal metal wheel that was same dimensions as my old one. If you have a non AC heater box LMK and I can get you the part number for wheel.

This subject vehicle is 72 SSP non A/C.

I'll check but think I just have a/c ones.

The part number I used was a 35604 Four Seasons(Murray is same company). I'm 99% certain it will fit your box as well.
Hope this helps.

Wait a minute! Since when did Mopar go to plastic squirrel cages? I always have seen metal ones, something ain't right here?

My 1970 road runner had a plastic cage when I pulled it apart for the first time last year.
