NuttyProfessor Posted June 29, 2014 Share Posted June 29, 2014 Only 2 reasons, crap motor or overheated the rotor. Did you check your temps as you went along? Quote Link to comment Share on other sites More sharing options...
Tug Posted June 30, 2014 Share Posted June 30, 2014 Yeah, that sounds de-bonded. Quote Link to comment Share on other sites More sharing options...

jea Posted June 30, 2014 Share Posted June 30, 2014 if the motor shaft has come away / de bonded with the magnets its had it .. some motors can be re built .. but must off the cheaper ones are throw away items . Quote Link to comment Share on other sites More sharing options...
nemo#1 Posted June 30, 2014 Author Share Posted June 30, 2014 ok thanks guys,its a tork engine on a savage hp,I haven't been keeping an eye on the temps,only had the truck a couple of weeks but bought it second hand and had this problem from the start Quote Link to comment Share on other sites More sharing options...
NuttyProfessor Posted June 30, 2014 Share Posted June 30, 2014 Invest in an IR temp gun and test your vehicle every few minutes on its first couple of runs, saves an expensive part going up to electronic heaven. Quote Link to comment Share on other sites More sharing options...
Vr5fx Posted June 30, 2014 Share Posted June 30, 2014 If the rotor has come off the shaft the sooner it is looked at the better, it will get worse. The other thing that I can think of is the brushes on the shaft are worn, or have been taken out. If the rotor has de-bonded you should see a performance decrease, (lack of acceleration or non at all) and high temps. I've repaired a castle rotor before, the repair worked for 2 months with no issues, but then it de-bonded again and pretty much went bang without any warning.

DeadMeatUK Posted July 1, 2014 Share Posted July 1, 2014 I accidentally pulled the shaft out by 10mm while removing a stubbon pinion, mine is a Castle 1515 so it's not limited to cheaper motors. What I did was strip the motor clean it up and added a drop of bearing retainer on the shaft and pushed it back into place, the shaft has a flat spot so the rotor can't slip while turning. This was 6months ago and it's still running, although it's had only 8-10 packs through it... So if you have experience rebuilding motors, it could be an easy fix?
