Heater Box Parts - Where to find???
 

Looking for the bushings inside the heater box.  The ones for the control arms and for the flaps.  Do they make them?  Also would be great to get new seals where the core tubes exit the box.

 

I can't even find a part # on realoem

 

Also, how do I remove the fan from the motor?  Is it just press fit on with the white plastic piece?

Thanks.

I think the control rod bushings and hose grommets are both still available--check with Blunt. 

 

As for removing the fan from the motor, it ain't easy, especially on the later fans that have a plastic hub.  Too much force will either shatter the plastic hub or separate it from the blades.  Both will ruin the fan.  If you're trying to salvage a good fan from a broken motor, the easiest way is to saw off the end of the armature where the fan is attached, the set the fan hub on an appropriately sized socket and carefully drive the armature stub out of the fan with an appropriately sized punch or drift.  But if both fan and motor are OK, don't try to separate them.  That's asking for trouble.

In the FAQ on Heater Box Rebuild, Chris mentions the sizes of grommets he used for what you mention.

Check out pn 64 11 1 353 352 for the grommets to surround the tubes.

 

If you replace the motor, they may not come with the little three legged "cover" which is NLA. You will need to reuse from the old motor.

Paul, i just removed my fan blade. I took 2 steel rulers and slide them between the fan blade and the motor and then using the steel rulers as support taped down on the motor shaft and was able to get the blade to move down the motor shaft.

Your local hardware store has some nice grommets, stainless and brass hardware for the heater box.  The heater box FAQ article is your friend.
