Interesting Motor

[ROH73]

An early no-stamp "Edinger" arrived today and this motor was in it. Kind of interesting; I've never seen one like it. It has ball bearings and a removable closed endbell. I'm curious about it, so does anyone have any info? Thanks in advance!

No info about it other than it is likely a "Big Jim" motor. Very cool though!!

Man, that baby is begging for restoration! Very cool. Can I see straight overhead shot of the endbell?

Here you go, thumb: a rear end shot just for you!

I love it! I’ll admit that I’m not at all familiar with these motors, but it looks like it comes apart pretty easily. I’d love to see the innards.

As for restoration, here’s what I would do. Someone may have a much better idea though. I’d take it apart and hand clean most parts. The bulk of the work will be the can and the label. I’d first clean the edges of the label meticulously with a needle or straight pin. I’m afraid any solvent at all, although helpful, would peel the edges of the sticker back.

After cleaning the edges of the label I’d back right against it with some masking tape. Then apply about 4-5 coats of liquid mask to the it. After removing the masking tape you can spray the can with an appropriate red paint and then peel the mask off without harming the label. The mask may even aid in cleaning the edges. Just my thoughts. Someone please chime in if you have a better idea or if you think the liquid mask would harm the label.

Cool item. What does the rest of the label look like (what is its condition?). Reason I ask, is that it looks like the label is in great shape but the rest of the can is a mess. Usually the label is the first thing to get messy, or at least they usually "decay" at the same rate. Just wonder if this is something, someone put on later and has little to do with the motor itself.

On a seperate note. When you pull the motor apart, the brushes should be mounted on spring like brass arms that will push them against the com for contact. Depending on the washers on the end of the armature they can hang up the brushes and bend the arms. So be very carefull pulling it apart. And when you put it back together, the "arms" that hold the brushes can be held back via the holes in the endbell, by putting little pins (toothpicks, whatever) through them from the outside. This will help avoid crushing the brushes with the commutator when the endbell is placed back on the motor. -Jeff

Thanks to both of you for the dis-assembly and restore tips. I think I will restore the motor; it's on my project to do list, and that's a long list, so it may be a white. I'll post pics when I do pull the endbell off.

Jay Dub: The motor label is in decent condition; the top mylar layer is staring to peel back at the edges, but otherwise it looks good. You make a valid point and it may have been added later. I wish I could get more info.

Regards,

Robert

I highly doubt this is a real Team Checkpoint motor, it also looks to me that the label was added on a 540 type stock motor.

would u open the endbell & show us what type of brushes are installed ?

Sure. I'll try to get to it this evening.

Is that a smiley face on the endbell? Looks like theres some text on the other side next to the red wire but its hard to tell.

Definitely an old school Igarashi mod motor, probably better suited to a 1/12th car, but not unheard of in an RC10 (or other car like a RR or Sand Scorcher) from BITD. Neat score! It would be nice to see if the arm is marked with regards to wind, probably in the neighborhood of 23 turns if it's really wild...

Back into hiding...

, how have you been in hiding?

[ROH73]

No smiley face; just a stylized IG logo. The text says Japan. So, Igarashi makes sense. Thanks, temple! Another member PM'd me and said it was an early 1/12th motor.

I pulled the armature and endbell out. I didn't pull the endbell off the armature, as the endbell bearing is quite tight on the shaft and I didn't want to damage anything while forcing it apart at 12:10 AM . Please see the pics; they're the best I could do at the moment. No markings on the arm or inside the can.

Very neat brush arrangement with hoods, springs, etc. It's almost like an inside out open endbell style.

yes, this is for sure the early made Checkpoint ! It has small form of brushes, which are same as the early 80's Trinity.
