Model 36 heater motor

[47Jim]

I’m sure the fan blade is pressed on the shaft but how does the motor release from the core? Does it just pull out after the the nuts on the two studs are removed or is something riveted to that center plate in the core?

 I don’t want to bugger something up, thanks

It is most likely rusted in place, but there is a set screw that holds the fan on the shaft. The two screws/bolts hold the motor to the housing.

 

I rebuilt my Model 31 in this thread : 

It might have some information that is helpful.

Thanks!! Came right out, I’ve got a great “old man “ type electric shop downtown that’ll rebuild it 

 

Question: those wires look huge, maybe 10 gauge or 8? What did you use?

[47Jim]

Well my old man shop can’t help on the motor going so far to say it’d be much easier to replace than to find someone to rebuild it soooo, I’m looking for a replacement 

Lostviking, you never posted a part number with that NAPA motor, you mentioned it was sourced for a 56 Chevy, that’d be 12volt also  
Anyone have a source for a 6 volt heater motor?

[Dodgeb4ya]

Have you tried to power up that motor?

Looks to me like a good one to clean up...check the bushings and brushes for wear if it does spin up.

Easy fix on the wires.

The old man probably is picking better easy jobs as being old.

When I was doing mine, I goosed it a couple times with 12 v.  Then gave the bushings, bearings a couple shots of 50 50 acetone atf mix and then another goose with 12 v, a little more 50 50 and let it sit for a day the ran it with the 6v through the switch it has an intermittent squeak in medium but is silent at least to my ears in low and high.

I'd have to look through my old gmail folders. Just do a web search for 6V heater blower motor. Then check the dimensions. I paid about $37 for mine if I recall correctly.

Some of those old motors had small ports for oiling the bearings .

Darn this thing, you have to drill out the end rivets to pull coils out just to get to the wires, it turns fine and looks pretty good, I’m going to try to tape up the wires and give it some juice

i would try shrink tubing before i would tape.

Have mine apart as well.  Once I get organized with how much of which gauges, colors, and lengths of wire I need for the whole wiring project, and get that ordered, I will rewire it, and cover the internal wires with heat resistant sheathing.  (Allied Electronics has it, as well as a lot of other places.  I have also saved some from household can lights my electrician bro-in-law threw out.)

What goes in this hole? This is the switch that was in the truck, I have no idea if it’s original to the heater, optional, newer or what.

This hole?

 

That is the resistor for variable speeds, gets hot under load if it is still intact.

I don't see any broken edges or anything on the ceramic part, I guess that's all there is to it, all the ballast resistors I've seen were solid, that's why I thought something went in this one to touch the coil somehow, like a fuse or something.

Got the motor up and running, if this switch looks complete, I'll clean it up best I can and see what it does with the motor. Thanks.

[lostviking]

The ceramic is just an insulator. The wire is the resistor.
