Wanted Heater Fan Motor or alternative (updated with a fix).

[Bobkat]

I have the interior all apart for refinishing and am taking advantage of the extra space to do some other repairs and fixes. The heater fan was noisy so took it out and looks like the sleeve bearing is well worn. Anybody have a fan for sale or an alternative motor to use?

 

[Dr.Jeff]

I recall a thread about replacing the bearings with better ones. Anyone have a link to that?

Is your car an AC car?

The AC cars shared its blower motor with the 320i of the same period. (As I recall)

The standard blower motor should be easily sourced.

It is a non ac car.

Did a little fix for the fan motor. I cut out the centre of a 6mm 1/4 spherical rod end bearing ( might have been a 1/4”) that I had kicking around and replace the well worn sleeve. Almost identical size. Ready for another 40 years.

Can an admin move this from the FS to a more appropriate thread?

A 6mm what?

A 6mm what?

sorry missed that part in the post. A 6mm rod end bearing. Now that I looked the shaft was .249 inches so it must have been a 1/4 spherical heim rod end.

Is the spherical end a bearing material? Meaning will it offer lubrication and not gall the motor shaft?

I would have thought a oilite/bronze bearing material would have been the correct solution for this?

The original looks like a soft graphited plastic material.

Perhaps one of these? http://www.spboilles.com/product/Electric-Motor-Spherical-Bronze-Oil-Sintered-Bushing.html

I would hate to see you have to take the whole mess apart again as a result of having the motor shaft seize on the bearing.

This isn’t something I know much about so your greater knowledge likely supersedes mine.

The original that came out is steel so is the replacement I put in. There is a felt pad under the c-clip type retainer that I greased. Since the last one lasted 40 years and still worked even with it that oval-ed just a bit noisy I am sure this will last whatever life is left in the car. It literally is a 10 min job to take it out so no biggy to replace it if it fails again and will give me time to source a replacement.

 

[Dr.Jeff]

I'm curious, how hard was it to remove the bearing/bushing from its mount? Looking at your pictures I can't quite tell what was involved (I've not tried it, but honestly don't think mine needs it).

Well... if you're interested in a new one, I think I have one for a late model X (non-A/C). I posted it on its own thread here in FS&W.
