Thanks in advance for any info

Ha ha, cool stuff... old skool! - I remember having a go at re-winding armatures (a mate even tried re-comming them too!) I had the same problem with the solder melting - I reckon they use higher temp solder from the factory? Of cause as soon as you'd re-wind the arm - the balance would be off, I tried using my dad's prop balancer (for his R/C planes) but it was a bit in-consistant to say the least.... Ah.. those were the days!jwscab wrote:you can get them apart, but it's not easy. you need a strong jewelers screwdriver that has a blade as wide as that tab, jam it under, maybe tap with a hammer, and gently bend them back. Once you get them more or less opened, you can push the shaft to help things along. Being a kid with no money, I used to pull them apart, and drill them through somewhere for a 2-56 screw on each side, and make them rebuildable (can't remember if it was 90 degrees from those tabs or near the tabs), then rewind the armatures with pirated magnet wire from other old junk. worked great except when the solder would melt on the low turn winds.
All 540-size armatures should fit into our 540-size cans, they all have two magnets (N & S) & three sets of windings (hence three segments on your comm & arm etc) The only thing you'll have to watch is the spacing - you'll have to add different thickness of shims each end of the arm shaft to make sure the brushes run nicely on the comm - also that you have the right amount of end-float.floodx wrote:Off topic question - i don't know much on rebuilding these motors and this may be a dumb question - but what are the limitations on just buying new inards (i.e. armature) and slapping it in a can - I know different cans have different # of magnets. But assuming the # of magnets are the same as the one required by the armature...
The easiest way to get them apart is to slam it shaft side down on cement or other hard surface. This is how we used to get stock motors apart.floodx wrote:
Says from Reedy catalog 1991 - I was running on a TQ10 so I am guessing it came out about the time the TQ was being sold. Tried to rebuild it but doesn't appear the can comes off on mine or more than likely I don't have the right tool for the job.
