Questions...questions...questions

Steve,  Specifications for the armatures you listed can be found in "J. L. Cowen's Postwar Lionel Trains O-Gauge Reference Manual I,  Steamers, Diesels & Electrics" by Robert A Hannon. CrowsNest Publishing, Clarksville, Maryland.   Earl G.

Does the replacement motor have a bearing on the motor plate, just below the field? Or does it have it's lower bearing on the plastic cover at the very bottom of the gearbox? As far as I know, the armatures are a bit different for those two motor trucks.  That is probably the difference in the part numbers.

If anyone can email me the armature spec I promise will ask for the J. L. Cowen's Postwar Lionel Trains O-Gauge Reference Manual for Father's day.

According to Greenberg you have 200 series power truck with part number 1055-118 as the armature. If you had an email listed I would send you the specs.

Thanks

Sent you specs

Actually as you and CW pointed out you could have one of two armatures. The 1055-118 on the gear end has a shaft length of 1.5/32. The gear end of the 600-125 armature has a shaft length of 7/32.  These lengths are from the end of the gear to the end of the shaft.

There is also armature 220-120 which is interchangeable with 1055-1118. 220-120 came out in the middle of 62.

Here's a picture. The black plastic cover says Lionel Switcher

I might have fixed it. Here are some pics. Found the split wire and spliced it. Did a ohms check and everything is balanced now.  I love my old Weller Solder station. I applied lacquer over the connections( Hence the protective paper on the shaft). Waiting to dry and try. I let you guys know how it went.

Thanks for all the help

Thanks again for all the Help!!!

The differences between the two armatures are:

Older one: has a longer tip at the bottom of the shaft. This tip rides in the bearing that is built into the dust cover at the bottom of the motor

Newer one: may or may not have the tip. It has a collar at the bottom of the armature head to act as a thrust bearing against the bearing that is mounted in the motor plate, which is right under the field.

Lionel sold a collar to slip over the older armature's shaft so it could be used with the newer motor truck. But sometimes the windings are too close to the armature's shaft to use it.

I understand that Flatcars1 fixed his motor. I wrote this for completeness.

The description of the 1055-118 armature by JustTrains states that it was also used in 600 switcher motor trucks. It appears someone substituted the motor truck from a switcher.

The switcher motor truck has a different coupler bracket / coupler. That is an Alco motor truck.
It is a bit hard for me to tell from the picture, but I think it is the later style, with the bearing on the plate between the field and the gearbox. 
This service manual sheet is for the older truck style, but it makes mention of the new truck style, and the collar I mentioned above.
And this page is for the newer truck style.

Thanks CW

The second reference is the Chassis I have, note the front light socket, All my Alco are based on that type of chassis, so I guess a 1066-118 would have worked. Good to know.

So much great Knowledge around here .....What a Great Forum attended by a a great bunch of people!!!

Thanks to all of you.

That's good work to fix an armature winding. Wonder how it got damaged - from a kid running it max speed ?  Or stray material got jammed in there?
