So over the last couple months I've accumulated some motors amongst the various other stuff I've collected.

I'm currently getting 2 Optima mids back into operational status (one will be going tonight) and an Ultima II so
I'd like to figure out what I'm working with motor wise.

Here's a shot of the lot of them minus the Trinity Midnight. I already know what that is and installed it into one of
the Turbo Optima Mid SE last night.

The other Optima Mid has the stock LeMans 240ST.

So yeah back to the picture. Here's the collection I'm not certain about.


First off is the black can Peak Performance with a Yokomo endbell. A lack of leads has prevented
me from testing this one








Next up is this pretty generic silver can. My guess would be a tamiya something or other. Seems to run okay
but needs new capacitors.




Then we have an East Coast Racing Motors Pink Can. It has some scratched writing on it. Theres a 17 and a 2.
There's more writing but I can't make out what it is. This one runs nicely.








Next we have a Team Losi Revolution in a silver can. This ones pretty worn. Definitely needs new brushes
maybe more.






Then there is the Team Losi revolution in a black can that's missing the armature. It has bearings in it. Would
an Integy armature fit this motor? If so what would be a good turn for this?






So yeah that's a lot of pictures.

Any information would be appreciated.

Thanks.

The motors that have bushings and a crimped end bell (the Pink EastCoast, the Silver Motor with No Label, and the silver Losi Revolution) all look to be 27 turn stock motors..

The Peak Performance motor could be any wind, but the wind could be written/printed on the armature.. (I have one that a 22 Turn).. I can see a number 17 scribed into the end of the motor.. This could be its wind, or it could also be the size of the pinion gear the previous owner used to run on the motor..

The Black Losi Revolution can should accept most modified armatures with some minor shimming..

Thanks for the quick response Stumpy.

Guess I'll look into rebuilding a couple of these.

Is there any way to update the stock motors with bearings? Just a thought.

If you are careful (not to stab yourself) you can pry back the tab that holds the end bell on in the crimped motors.. From there you can open the motors and replace the bearings and re-true the commutator like you would if you were rebuilding a modified motor or a modern rebuildable stock motor..

If I was rebuilding them, I would be looking at getting the commutators trued on a motor lathe, and replacing the brushes as my #1.. This is where you will probably find your biggest performance gain..

If the bushings are not worn then you probably wouldn't see that great of a performance gain by changing them to bearings..
