307 Drivers

My problem was the plastic separation from the outer rim. OIl was in the crease so it had to be thoroughly cleaned out. I started by stripping the engine.Then I pulled the wheels.



I used the Goo Gone for cleaning.


AFter some Super glue I pressed the section together. One was stubborn and I had to use a washer and Aluminum flashing. The washer raised the pressure over the inner hub while the flashin protected the front surface.


I had one rim come apart while pressing through the worm gear. SO I reglued that and letting it set the night.

It's like an educational slide show. I only recently learned that the white was plastic.

So getting ready for the wheels I noticed on axle has a taper or a larger side.anyway it was on the worm drive axle and it went into the chassis only one way.



The next trick was to line up the Worm gear. I used small washer cut open with a dremel to provide the spacing I needed.
Place the rods on for a roll check. OK


Nice brickwork!

Motor Test

In testing the motor I noticed play in the armature so I added a spacer. It helped a lot.



The shell was next. Stamped Mar of 1954. The engine running and together again.


Next step is the eunit on the tender to see what happened with forward.

It might be me looking at the pix, but it seems like your quartering is off?? Never mind, it's running, and it's right,lol...I've read somewhere that the armature plates should be at the same height as the field plates?

On the top right picture, the left wheel. The stud is at the bottom. Then the bottom wheel is forward. They are 90 degrees off but one may be off so slightly. It is harder, when you don't have a gear tooth to rely on as in the Lionel.

The height is on before it was bouncing like a kangaroo. You see I have never had this engine running.

Jim, it gave me the idea to reverse the coil wires. It needs attention I should pull it apart and rebuild. Maybe work on the connections. I have a front drive problem too. I need some spacers. Another step backwards.

Before you give up on it, try this. Cycle the e-unit until you get to a spot where the engine should be running,(not neutral).With a toothpick, push on the fingers to make sure they are making contact. I had the same problem with a 302 and it was driving me nuts.I asked Don Roder, owner of GarGraves Trackage, and whom I consider a friend,what I was doing wrong. He told me even though the fingers look like they're in contact with the drum, they might not be. Sure enough, that was the problem for me.

There is no doubt about a bad connection. I have tried the pressure point. I just need to use the meter and figure out the wire lineup when the drum turns.

Timboy, you are a celeb. I read some of the stuff at CTT.

I would like you to make a section and have a camera snap every 15 seconds or so then compile them together. You definitely have the system down. The vendor of Port Hobbies also knew your work too!

Bob, for spacers in a pinch, copper tubing, 3/8" outer, 1/4" inner. Works every time.
If you need a reverse unit, PM me!

Merry Christmas!

Beautiful work, Bob! Don't you just love working on something that old, that was built so well?

I actually have wheels spacers. I used them on the armature shaft. It wasn't until the engine drove off the rail on the corner thatr I remembered they were on the front axle. They fell off when I pulled the wheel.

The super glue is holding. The e unit is pulled amd now I am just trying to get it running. I had a a snag in both push rods and had to hammer them straight.

Just full of surprises. If I visit Port Line Hobbies I will tell then you said HI.

With the 307 tender I did learn that a weight is needed. I am not sure if I have one in the 300AC. Something to check out.

Those worm gears are a pain to press. I recall the same experience with my F-3. The Lionel 259e was a snap.

Bob, with the armature removed, do the wheels turn freely? If they do, have you tried using a washer(s) with the armature? My 300AC had that short type of problem and it turned out to be the lamp(not the fixture, but the lamp!)

Yeah I think I will disconnect it.
I may go round three on the wheels.
There has been some drag in the crossheads.
At least nothing is burning up.
I going to give a rest for now, maybe later on.
