Quiz of the day, I am taking apart a spare heater motor from a TR6 (I think they are basically the same TR4-6) and a spring comes out of the casing, it is a compression spring (no hooks on either end), slightly less than 1/2" (0.46" on my caliper) in length and about 0.19" in diameter. It cam out when I took the motor apart, could not tell from where, event when I took it all apart, all the parts that seemed to be needed to make it run and hold things in their proper places were there without the spring, so I put it back together without the spring and it works fine, but don't want anything to blow up or wear out prematurely. Don't think there is an exploded drawing of the motor in the parts books, so no help there. Maybe more precisely than what am I? Where do I go and what purpose do I serve, some kind of spacer with a little flex maybe?
 
Perhaps a brush spring that was replaced but left in loose after a prior repair or rebuild?
 
When I first saw it come out I thought it was a brush spring but it has way too much tension and is much heavier guage wire than the brush springs.
 
Yeah, as I recalĂł he sentido the motor Soutwest forma rebuild, But good stuff on taking Ethernet box apartado, etc.
 
Those springs (should be 2) go over the two bolts that hold the halves of the motor together. Look at the 11th picture from the top of the page Bob Danielson posted. Not sure _why_ there are there, maybe for vibration dampening.
 
Whoa, somehow my smartphone decided it was Spanish, and when I posted from the not so smart smartphone it did funny things with my words, I made my flippant answer from memory of my review of the site, but there you are, I see the springs, so now I need to figure out where the other one went, know I didn't stick it where it goes, and I only have one outside the motor, unless the other one went flying???
 
thanks a lot for the input, probably good to have the commutator brush holder stabilized, never did find the other spring, and I don't think the motor had been apart before, but I did make sure it wasn't inside, stuck to a magnet, and I found a spare that matched up very well once cut to fit.

As I make all the heater parts for the SMITHS heater motors I have all the SMITHS tools to make all the heater motor from the 1950 to 1990
and I do make the TR4 TR5 TR6 heater motors

I am all buttoned up and good to go, but always good to know about where you can go to get things done right. Thanks, Greg
