Disassembling an old Associated 05 motor
Posted: Wed Aug 31, 2016 4:42 pm
This came with a RC10i that I picked up not too long ago. The motor has seen plenty of use, and sounded absolutely horrible (screaming like a banshee), so I decided to pop it open and see what's up in there.
I'm sure some of you have done this before, but since it's a tabbed can - not supposed to opened and serviced - I'm guessing some haven't seen the innards of one.
It's pretty much the same as you see in rebuildable motors, with a couple exceptions, the most obvious being the permanent brush setup. Also, I didn't know the bell bushing was actually round, and can spin a full 360 degrees in the bell. In pic #5, you can see I have the bushing turned 90 degrees from its normal position.
In pic #4, on the far left of the armature is the front bushing, with grooves that fit into the end of the can, if you look at that in pic #3.
I didn't see anything right off the bat that would have caused the noise...until I stuck a finger in there to see if the magnets were moving or something like that. They were fine, but as you can see in pic #6, it was FILTHY in there.
So, my plan was to clean everything up and put it back together, and see how it acted. I was even thinking of truing the comm, but I can't find my lathe
so I guess that won't happen.
