Hey guys, looking for a little help as I am no Charger expert but helping a friend rebuilding a motor.
I’m OK on the functionality but would like to get a few things cleared up on details.

Many motors I’ve seen restored have a flat tip pan screws in the 5 locations that cover the gears, the motor I was given has Phillips head screws as do many I see unrestored for sale in EBay. Guessing this is a year thing but ??

Doing a search I found some old images from Jules (so my confidence is high) that show what’s painted or not.
-Are the 2 screws in the winding barrel really not painted black with the barrel?
-Why are the wires colors varying? And shouldn’t they have what looks like a heat shrink or rubber tube over the wires? (ref the yellow, red, and green wires).
-The wire clamp that holds the connection, is that supposed to be painted or left as bright zinc?
-The manual turn knob, painted or Zinc Phosphate?
-And finally, the motor cover plate (side of manual knob) is that bright zinc or bare?

Based on the one I was given it’s difficult to make out what finishes were on any of it (was pretty bad to start, but certainly appeared unmolested). It’s got the smaller manual turn knob as well

Here are some images form our friend Jules and a final pic of one done by Stephan (Jules successor)

Thanks for the help.

This link is to an NOS motor that will give you a good idea of how they were made:Link

Certainly some differences over the years.

That one may be NOS but appears it way have been made in 1978, and certainly adds to so many questions I have.

I certainly don’t know enough about the Charger platform but I know MOPAR well enough to know that NOS and factory installed original can vary more than a bit

Appreciate the link, still good to see and a great ref

I have an NOS motor on my 70 Charger R/T. I will see if I can get a few photos of it.

Had mine restored by Bill Meerholz but I’ve got one still on the header frame of a 70 Charger at the shop. I can look in a few minutes.

Here are a few pics of my 70 NOS motor. Installed it about 4 years ago. If you need other specifics let me know and i will see if I can get additional photos.

First let me say I really appreciate the effort of supplying photos.

When you said it was an NOS motor was it the original motor to the car or a parts counter motor?

Here’s what appears pretty solid based on the pics you supplied and some of Jules/Stephans work.
Best I can tell your motor appears to have a 1970 date code (if I’m seeing it correctly) very early 1970
- The 3 attached bolts are zinc phosphate
- The 5 gear cover screws are flat tip pan heads or more importantly, electrodeposited bright zinc and not painted
- The motor barrel is painted a low sheen black
- The two wires from within the motor DON’T have a protective rubber cover shielding them

What I’m unable to confirm:
- The two CSK screws in the barrel are they flat tip or Phillips?
- The two CSK screws in the barrel are they painted black or left plated bright zinc?
- The drive side of the motor, cast cover, appears to be painted black (similar to the 2nd image of the Jules motor above). I notice the header it’s mounted to is blacked, is this possibly over sprayed on the cover?
- No images of the manual hand wheel but suspect black (all redone images above are consistently painted)
- The pigtail wire clamp I can’t make out, guessing black or it would shine in your 3rd pic)
- The barrel cover plate opposite the drive side appears unpainted, is the cover bright zinc or a bare steel cap?

Thanks again

Here’s mine restored by Bill Merholz. It’s my original one. I’ll look at my unrestored one at the shop.

Here’s the one on my extra grill brace and one I have labeled from a 70 Fury. The one on the brace has a 73 date code They are all three different part numbers. The one on my car is dated correctly so I assume it is the original for my car.

So, in looking at mine. None of them are “painted “. Looks like plating was all they got, then assembled. Bill is very precise about his work so I would say his is correct by looking at my unrestored pieces.

Well first and foremost. . .
Merry Christmas !!
I hope all are able to enjoy the day with loved ones

Well we all know Bill does great work, certainly not a guy known to slide on details.

Your installed (Bill redone) motor shows closer to details I found on the one I have, with cross tip barrel CSK screws (not painted), pigtail wire hold (not painted), and a protective cover over the motor wires. It also appears to have the gear side casting with a finish other than bare. The motor I have it appeared to be painted black but was pretty blotchy/worn and unsure if that’s the result of a thin application or overspray during blackout of the mounting header.

On Bills restored motor it appears he did the same finish on the manual turn wheel as is on the barrel. Best guess is some sort of zinc phosphate with an oil (traditional for zinc after plating but usually not detectable the way I see this one) maybe a thicker oil or a light cosmoline. Digging around on old unrestored photos on motors with the small manual turn knob, the knob is noticeably more rusty than the barrel, leading me to believe it had little to nothing applied to the surface. (Similar to your Fury motor of the same period and the way the unit I have appeared)

Finding it difficult to get a solid read on these with the variations. Ideally all examples would be unrestored but almost all examples I’ve seen are in pretty poor shape.

You sure that Fury motor isn’t painted?!?! Sure looks like a light application of black that’s been weathered and worn.

I feel like I’m running backwards . . .

So I look in the 1970 parts catalog and it states:
1970 Charger or Charger RT is PN 3431 438
1970 Fury is PN 3431 437

Meaning there is no mention of the 3431 211

Was the 3431 211 replaced by the 438?

I have no clue. I’m guessing mine is the original one on my car new. It was parked in 79 with only 65,000 miles and never left the garage until I bought it. It has lots of its assembly line parts still on it. It was built April of 70.

No, on the black paint on the Fury motor. It’s got a plating on it of some sort only.

OK, I’ll play around with a couple finishes and see if anything mimics an unrestored motor.

I also went back to look at the NOS motor link posted up by 70gtx440dana. I recognize it’s not a 1970 built/installed assembly line motor but suspect the finishes MAY be similar. Just another ref point.

Back in the old days this sort of question on this A12 forum would have had a ton of folks jump in with more info on dates, finishes, PN’s and variations seen. Unsure if all got tired of looking and arguing, moved to other forums, or have died off, but it’s a little depressing. With time true history will be lost

Sincere thanks to those who have been trying to help me on this topic

From my research the 3431211 motor is correct for 1970 Charger. Two photos attached.... the "70 only" parts book showing 211 motor and 70-71 parts book showing 437 motor. I tend to believe the 70 parts book as I have looked at many 70 Chargers and mostly see the 211 motor.

The case/barrel screws are bright finish and Phillips head.
The barrel is not painted...it is a black plated finish. Very thin layer of coating. All the restorers paint them and it is not correct to OEM. This is why I hunted an NOS motor. Mine was NOS stock in box and never mounted.
I will check on the details for your other questions. PM me your phone # so I can text additional photos. Joe

Note: the 211 motor has two different knob styles. Large knob is considered early. Small knob considered later in 1970 MY. I do not know a breakpoint. Mark's pic showing 0400 date code has small knob. My motor is dated 0260 and has small knob too. So, I am thinking large knob was changed to small prior to January 1970.

Took a couple more pictures with better lighting. See below.

Drive/motor housing seems to be plated the same black as barrel. Knob is natural/clear finish.

Great, that helps, I have a 70-71 parts book printed Jan 1972, so 211 PN it is, though 437 would functionally work.

And thanks for the additional pics, yes, much better lighting.

I think I’m somewhat decided on what’s needed, just need to get to work on executing.

Thanks again for the help

Good information, Joe. Never thought about a difference because of the date of issue on the parts books but it makes sense. From my viewpoint, it looks like Bill nailed my motor restoration. He’s not cheap but neither is the plating accuracy. As far as the participation in a thread nowadays, it seem that we are loosing members with knowledge or time to help. I try my best to help out in areas that I have some knowledge. I can usually learn at the same time. I occasionally search a question and find an old thread where Bill Overcash and I had a conversation about carbs. Who knows but I hope someone in ten years runs across this thread and it helps them.
