Tips and tricks to get wiper motor outer housing off?

[Dana67Dart]

Picked up a wiper motor core.

67 Dart 2 speed???

It seems to be frozen. I'm trying to get the outer motor shell off.

I have tried light tapping around the shell where it mates to the gear box.

Tapping down where there is a lip I can tap on.

I put some light oil on the seam (can't find my penateating spray)

I have thought about a strap wrench to get it to twist a bit. The posts partrude so I can't turn it much.

I'm thinking about some localized heat.

Thoughts?

Successes?

Sure it's not a variable or three speed? Should be some numbers you can search.

My two speed...

It's a 66 67 not a 68 up that sticks out into the engine compartment.

It has 2822963 on the housing.

Only 3 wires coming from the bulkhead connector ( looks identical to my oem 2 spd )

Same park switch, same wires.

I'll look at my pn and see if it's the same

My 67 Dart 2 spd wiper motor. Same part number.

I never understood why they changed from the worm drive to the gear drive that sticks out into the engine compartment.

The worm drive huggs the firewall

I think it was a mfg change? Contract?

As you know, that pnn aka the 'white switch plate' motor supposedly used on '66 B bodies as well as 67 A bodies.
See if the parts book and FSMs show an exploded diagram.
Occassionally I've seen parts for sale.

Also look through posts from @moparmat2000, and maybe if he sees this he can give you some guidance.
Here's a one he took apart.

Once the bolts are out, I just use a rubber mallet if it doesn't just pop off.
