This week has been spent resurrecting a project that I was distracted from about a year ago. The operation began with the remotoring of a Lionel B6 from 1989. Here we see the subject with it's new can, a salvaged motor from an old copier. The first place I started was cobbling together a new tether and wiring harness to provide for the upgraded electronics to be installed. Rerouting of the wiring for the smoke unit and other engine accessories are roughed in. A new 8 pin connector was fashioned to pivot so that a straight through tether can flex some, although not much flex is needed with minimum 072 curves.
Concentrating now on the tender, I set to work modifying the trucks to open the webs cast into the arch bar frames. Another mod I attempted was adding brass bushings for the axles instead of the original Delrin types. It was an experiment that really didn't improve things much so I stopped at one truck. Here's the modified rear truck before painting with a scratch made coupler mount so that the claw doesn't hang 1" past the tender end.
Last, the front truck is modded to collect both common and center rail power. this is the truck with brass bushings. With the original tender being electrically isolated I felt that adding more power collection here would help keep the engine from balking on turnouts and such. Obvious new holes in the chassis were previously made during the pre-fitting stage to accommodate new ERR electronics. I'll be proceeding with buttoning up the tender tomorrow now that the big mods are done. Hope you enjoyed so far.

show us more! Love these upgrades! Where did you find the motor?

Thank for your interest, Jdaddy. I plan on continuing the upgrade documentation to completion. The motor is out of an HP inkjet I cannibalized. A bit too large to be hidden inside a backhead but way less space consuming than the original Pullmor.

So I am curious. How did you know this Motor would meet the right gear ratio and voltage requirements for this upgrade... I may have to consult your expertise on a Williams Brass PRR 0-6-0 I have retired in the park! Its the perfect candidate for an ERR upgrade.

This is an interesting project Bruce, way out of my comfort zone but very cool.

Very interesting and your modifications look great. Looking forwards to updates.

Terrific project, Bruce. Please update this as you work to complete this project.

For sure, the enthusiasm to see this project completed is high so I will continue work while updating here. There will also be more cosmetic improvements performed in the process. The 18000, AFAIK, has many non B6 features, like evenly spaced drivers. I will add some PRR specific details but he warned, this is not an attempt at a scale B6sb.
JDaddy, motor selection was simply scroungers luck. Anything in the 12-20 volt range could potentially be a candidate. An important motor characteristic is how freely it spins when turned between finger and thumb. When there's no resistance felt, a cogging effect, you usually have a winner. I will report on the running characteristics when I button things up but preliminary runs have been smooth, quiet and slooow.
That 30 year old William's B6 would greatly benefit simply from an ERR Cruise Commander installation of you operate CC.

Very cool use of a recycled motor. Watching to the end

Great project BRUCE!!! How did you cut out AC motor and what size is the fan motor. I have a TMCC 18064 Lionel Mohawk that I would like to experiment on changing the motor and upgrade the electronics. Keep us posted.

Hey laz57 The old Pullmor unscrews from the chassis and the brass gear was pressed off the armature shaft. The new can gets a common mounting ring ( the type with 2 attachment ears found in basic China drive diesels ) and new holes drilled and tapped in the chassis mounting face that line up with the ears on the ring. Because this motor rests directly on top of the chassis tail the wire tie here also serves to prevent vibrations. Otherwise, all gearing remains original.
I have only tackled one other Pullmor motored conversion, a late 90's C&O Yellowbelly. That's a whole 'nuther can of worms.

Thanks BRUCE. I am going to watch your progress and maybe rip mine apart in the fall. When done please post video.

Very ambitious project. I have never attempted anything like swapping different motors (although I suppose the new one doesn’t know it’s powering a model engine and not a paper feeder!)
Excellent effort and keep us posted. Would like to see how it runs with that motor.

Interesting resto-mod style project. I too am interested in how to worked out the gearing part. I

An update will be posted tomorrow. I ran the partially assembled current results and took note of how lady like she stepped. Speed step 1 gets a creep of roughly 1 driver revolution in 6-7 seconds. Again, that is accomplished with no gearing changes. Till then.
