I am interested in learning what it takes to rewire an OEM 6V Delco motor found in the Harrison fresh air heater. Is this going to be like opening up a can of worms? I simply want to replace old cloth wiring with some new cloth wiring w/o biting off more than I can chew. The motor runs fine; when opening up the housing I do not want to monkey anything up. Any insight is appreciated as always.

You MIGHT find that the wires are soldered to terminals in side the motor casing. Best case scenario, and you could just resolder your new wiring to those terminals. At some point the feed wires that you want to replace have to transition to the varnished wires. Full disclosure - I have not opened up a heater motor. Good luck. Let us know how it turns out.

I had one apart the wire is probably fine I put some shrink wrap around we’re it goes through the motor housing and when you take it apart there are the brushes just like the starter that you have to be carefull with as they if I remember correctly they have springs behind them .I also put a little more grease at the two ends were the bearings are .If it is running okay and not noisy the easiest and (no opening of the can of worms) would be to cut the end off and slide some shrink wrap down through the motor housing without opening it up then put a new terminal on the end .I think on Dave’s tec net site he he’s a heater motor that he took apart to use the housing to put a newer 12 volt unit inside using the old housing ,there may be some pictures that shows the motor apart that may help with your decision to open it up .

Here is a couple of pictures from Deves tec net site of the 6 volt heater motor .So when I had mine apart I never pulled it completely apart just enough to put a a tip with some grease at the end bearings and the wire inside looked good except for were it came out of the motor housing so I used the shrink tube . I think it would be into the can of worm area to pull it apart were the brushes come off of the armature and have to mess with the brushes and springs .

Do not want to open up a can of worms. Sourcing a good used motor is the route I am taking. Thanks for the advice.

If you the motor is still good you could do what I did ,the wire covering was worn were it goes through the motor housing .I opened it up to look at the brushes and was able to put a little grease on the bushings without pulling it to far were the brushes would fall out ,Other than that if you want the original look you could slide a piece of cloth loom over the wire.I don’t think you would have to take the motor apart to cover the wire maybe with a dab of silicone on the end to hold it from slipping up the wire.

I found the exact size and shaft I needed for my aftermarket heater at Grainger. I don’t know about your Harrison. Worth a try. If all is good and you are just concerned about bad insulation on a couple of wires and can’t use shrink tubing, use “liquid tape”. Carefully brush on your coating. Google it.
