Heater Motor Wiring Replacement

[40 FourDrDlx]

Need some help replacing the heater motor to switch wiring on my 40 Deluxe hot water heater with a 46-48 switch. Got the new harness & opened up the motor, I'd previously tested the motor & it ran fwd & reverse. The new wiring has to be soldered into the motor & the brush wires are easily accesable , but the field wires are in the bottom of the case & hidden. So, does the field assy. just pull out of the case to access the wires? It seems pretty tight & I didn't want to force it since I don't know what I'm doing.
The old original wires all seem to be similar shades of brown & not identifiable with the color codes of the new harness & wiring diagram. how do I ID the "short field wire, long field wire, fwd brush wire, & rev brush wire" with the proper terminals?
The inside of the motor is black & dirty with carbon from the brushes, can I spray this with brake/carb clean or ?.
Thanks, Bob

They make spray cleaners for electrical applications, I buy it at my automotive parts store. Carburetor cleaner is bad for rubber, it and brake cleaner will both attack paint and possibly the varnish type of motor insulation.

Sorry, I can't help with how to take your motor apart.

I hope someone can post a good simple diagram for this. I have a NOS heater in my 47 that I have never wired to the switch.

Post # 12 of this thread has a heater wiring diagram. When you bring it up go up to the tools symbol on the upper right of the tool bar and zoom it to 200% so you can read it. Good luck.

Thanks but I have the wiring diagram, what I need is a diagram of the motor showing color codes or terminal names to match up with the wiring diagram. Does that make sense?
Also, has anyone removed the field/coil asy from the case & how?

Correct, the wires are not identified by color and not sure 40 is the same as 46-8. Does anyone have a 46-8 diagram that shows switch terminals, location of wires and color code of wires?

Thanks Jim, maybe I confused things by mentioning I was using the later switch. The wiring is the same, the only difference is the type of terminals at the switch.

Come on, a few of you out there must have done this, what's the trick?
