Lionel AC Pullmor Motor Conversion to DC Can Motor with TMCC Wiring ?

Did you look at the CCM instructions?  The Cruise M J3 connector is AC input 2 wires and Motor lead 2 wires.  SO the other wire goes to ground.

The AC motor needed both brush wires and also field wires (usually one went to ground) hence the 3 wire set up yel, green, blue. G

I’m confused. Since going to DC motor NONE of the original command control electronics can be re-used. Are you trying to use the Cruise commander “M” with the original AC  electronics? It’s designed only to work with Lionel original system already utilizing a DC motor. 

Ron, that's not really true.  If he has modular electronics, replacing the AC motor with DC would than just involve pulling the ACDR and replacing it with the CC-M.  The R2LC that was there currently would still be usable.

How about an overall picture of the electronics you're still using in this engine?  The exact model number would be useful here.

The Lionel number is 6-18879. I’ll send an overall pic around 6pm EST. Thanks. 

Here's a couple of pictures of all the TMCC components including the Pullmor motor still attached.

Newt, something I did a couple of years ago when I was contemplating converting 40+ conventional locos to TMCC was to download all the Lionel shop manuals and study them whether they were conventional, TMCC with pullmor motor or DC motor.  I printed out and enlarged schematics of something with an LCRU2  another with a DC-LCRU and DCDR single and dual motors and modular boards with R2LC radio motherboards for motor and sound.  My HP printer software will allow me to enlarge the schematics on 2 or more sheets of paper it really makes things easier when the schematics are larger. I used colored marker pens Red for wires coming from the center rail, black for common / ground wire and whatever else looks tricky. Attached is a SD40 schematic that is printed on four sheets of typing paper.  It really does helps.   Also a link to a site with most of the Lionel manuals.  Easier to access them here than on the Lionel site.          j

Folks, here is a perfect example of why, if at all possible, post your photos in a horizontal format.  These are the same size photos but look how much larger the horizontal photo opens than the vertical when you click on it.  Click on each of these and look at the difference.      j

My advice still stands for the 4 pin connector in center of the CCM.  AC Power and Motor Leads.  That does look like an early RS set up, so will be interesting to see how it works with CCM.  G

I think we're giving the same advice George.   He already has the 4-pin connector with the CC-M, all he has to do is wire it properly to the motor and track, job done!

Maybe you and I are, but others chef's in the kitchen too?   The original question is very simple, and answered by me on my first post.  G

I wonder if it's running now?

Thanks for everyone's help so far. Here's a pic of the Can motor installed. I attached the Green (Ground wire) to the center of the chassis. The blue and yellow wires to the motor and the red wire to the center rail pickup. The random black wire that was attached to the old Pullmor motor is "tied-off" (not attached to anything). If this looks correct to everyone, I'll give it a try tomorrow. Let me know what you think.

Looks OK to me if that's the connector that came with the CC-M, the colors appear correct.

Trace the random black wire.  If that went to the coupler as ground on the AC motor, it needs to go back to ground on the chassis for the coupler to work.   Same on rear if it was done that way.  G

Hmm, I put her on the track, did the programming (code 5) and she won't move an inch. Everything else works, diesel rev, horn, bell, strobe light, front and rear couples, crew talk, lights and direction. I am going to connect the  random black wire to the chassis with the green wire. I referenced the website of schematics provided by JohnAction and it looks like this wire should be grounded. I let you know how this works out tomorrow. Thanks guys.

Where is your red wire out of the 4 pin connector on the CCM going? 

George, according to his first post, he connected it to track hot (center rail), which should be correct.

The red wire from the CCM actually travels to the motherboard first, from the  motherboard it is then connected to the center rail pickup. 

That's how track power was wired originally, that's fine.

Gentlemen...SUCCESS!!!

Connecting the black wire to the chassis did the trick. She runs very smooth, slow and quite. I did encounter one problem which I didn't anticipate. The new can motor is significantly taller than the old Pullmor motor and the top of the motor touches the cab light when I install the shell. I am in the process of relocating the cab light to a more forward position. This is actually a good thing because the cab light also doubles for the headlight and the headlight was never as bright as it should have been. Thank you all for sticking with me and offering all your ideas, suggestions and knowledge. I have definitely learned a lot from this project. I love this forum. THANKS GUYS!

Sounds like you did not have a good ground without that wire attached.  Glad you got it.  G

Success stories are always good.
