Chrysler Royal, M6 transmission, fluid drive

Ok, now, I have a new question... it is semi-related to this subject..

All the wiring in the car is iffy... every strand. If you touch it or move it, the insulation cracks and falls off. I bought a generic wiring harness which will handle the 6V system. I looked around a bit and seems like it would be about $1000 to get a "concours" quality wiring harness, so that wasn't an option. Besides, there is a nice fuse block with relays and GM blade-type fuses to make life a little easier (maybe)... and all the wires are marked for the entire length of each run.. it's actually very nice for the money.

So, the question... the car is positive ground. I'm assuming the wiring harness I bought is negative ground.. but I don't know if the wiring harness will "care" which end is ground.. does it matter? there aren't any diodes that I have seen... Maybe this seems like a dumb question.... but I don't want to let any smoke out of any wires.. The only reason I ask is because I have a couple of older aftermarket electronic ignition boxes that say "negative ground only"..

Let's say I went ahead and switched over to 12V negative ground. The 'new' engine came with an AMC 12V alternator with the huge pulley to match the crankshaft. Would the governor, solenoid, and interruptor switch wiring on the transmission need to be changed? I'm thinking about it as I type and it doesn't seem like anything would need to be changed in the system except the large wires at the battery (negative to chassis and positive to starter)... would reversing the ground and positive like that cause any fuses in the system to be protecting the wrong end of the circuit? Am I talking out my rear-end? LOL

Sure, that would be appreciated!

OK, the O'Reilly part number for the oil is Line Code = OIL, part # = ND10

Take the line code and part # to your local O'Reilly's and they will get you the oil

The reason O'reilly's isn't on my 'first' list is because the prices are usually higher for the same parts and because of stuff like what happened yesterday. The guy didn't even want to look up anything.. didn't want to be bothered. I receive that attitude every time I go in there. He be dissin' my old-ass 'tranmission' too.. LOL.

The reason I ask is that I am a manager with O'Reilly and was curious about your experience. The part about the prices kinda surprises me since I have found the opposite to be true in my market. We do have a low-price guarantee so if someone has a lower price, we will match it. Sadly, the personenel varies from store to store, but believe me, the coprorate office puts a great deal of attention on superior customer service... sorry about your bad experience.

The NAPA, advance, o'reilly's, and autozone(which is the LAST one on the list) are all within about 3 blocks of each other anyway.. the people at the Advance seem to be the friendliest. Napa has the best filters.

I used a similar harness when I restored my kid's Jeep and they are quite good.

The wiring harness doesn't care, but you must be conscious of the positive ground while doing the wiring. Fuses should always be placed "before" the load to protect the circuit downstream.

All items that were designed to operate on 6VDC must be changed to accomodate the new 12VDC power source. There are however adapters that can be used to "step down" the voltage to all circuits except the charging and starting circuits. This would eliminate the need to change "everything" over to 12VDC.

Yes!

Am I talking

No!

Ok, you have convinced me to leave the car 6V positive ground for right now. I appreciate your input, definitely! My 90 year old grandfather is the driving force behind getting this car back on the road and the simplest route is the best at this point.... he will probably live forever, but i want the car to be back on the road sooooon just in case he doesnt live forever... lol

Maybe I missed it but what is the year and make of the vehicle?

Look at oil compressor oil I believe it is 10w

Intersting thought... I've some (synthetic) compressor oil in the shop, I'll see if it is marked with a viscosity. If so I'll post the part number (it is IR oil)

Believe me when I tell you that synj oil may very well be too slippery to use.

GM a couple of years ago was voiding warranties on some transmissions due to the use of Red Line Syn for that reason. ymmv

Interesting... I'd not heard about GM doing that, and I use Red Line Synthetic High Temp...

They did on the ZF box used on the Corvette.

Well Mike, I finally called the O'reilly's here in town again to find out about the 10W oil... gave them the information and the guy came back and said the Atlanta warehouse had a whopping 2 quarts on-hand. The manager wasn't at the store today, and the guy said that he was not allowed to order a 12-case for me until the manager is in. Glad I called first..

Another thing that's wonderful is for the past 20 years, my dad has been telling me "oh yeah, i replaced the kingpins"... so I replaced the wheel bearings without really investigating only to get them tight and discover the front wheel still moves out 1/4" at the bottom... kingpins!! wooohoo! Probably will have to find new stub axle carriers since these kingpins are freaking TRASHED.

Sometimes I wish I was a freaking idiot and didn't *want* to fix broken things. Life would be much simpler..

Why not just replace the king pins and bushings? It's not terribly hard. Your O'Reilly store has access to a company called "Rare Parts" and can get most any steering/suspension parts for the old 'gal.

Mike

If you have probs getting the oil, let me know.

Ok, thanks for the tip on the front-end parts! I'll go check it out! The only thing i'm scared of with the kingpins is A> the pin is mangled and won't come out and/or B> the pin comes out, but the knuckle is worn out from neglect.

I'll let you know how it turns out.

Who knows, you may turn me into an O'reilly's believer after all.. :D

Rule #1 - KIng pins NEVER come out easy... they're king pins... that's what they do!

and/or B> the pin comes out, but the knuckle is worn out from neglect.

Rule #2 - Replace the worn king pin bushings and the knuckle is unharmed and lives to fight another day

I'll let you know how it turns out.

That's the plan....

;^)

Mike

Please post pictures when done!

Don't know where you are located but there are numerous aged rusted cars in yards and fields along 27 in Ind. Gotta be a knuckle there if you can't rebush the one you have. If you can't find a new one you could always build it up then take it down to spec's.

I will post some pictures of what I have done thus far, if'n you're interested :D

Hopefully we won't have to do that :D

I am down in the deep south.. most stuff is hidden away around here. I haven't found any junkyards with really old cars.. guess i haven't talked to the proper old boy yet!
