Other than the obvious puff of smoke or near nuclear meltdown... How can you tell if your brushed Titan 550 is going bad?
Last weekend after running the Maxx I was going some cleaning and maintenance. I didn't do anything out of the ordinary. But this time when I sprayed a little CRC in the motor to clean and lube it (as I've done many times before) the motor (can't remember which one) gave up a tiny puff of smoke and a burnt smell. It all seemed ok, I wrote it off as excess CRC getting ignited.
Today I was out running and the ambient temps was higher than its been all year, Id say it was in the high 80's at noon time. After about 5 minutes of running I could smell a strong electrical burning smell. I didn't think it was my truck at first because it was 30-40 feet away from me. I thought no way could that strong smell be coming from my truck. But yep, it was.
I let it sit for a while to let it cool down. Everything was hot, not ridiculously hot but hot. I finished up running my two packs. I could still smell the electrical burning smell some, not as bad as in the beginning of this running but still you can smell that hot electric smell.
Performance didn't drop any, batteries aren't overly hot and overly discharged.
The only other check I've done since I've been back home is to remove the spur gears just to make sure that both motors were turning and they are.
I guess it may be time for a motor upgrade before I get that new body.
I'm leaning towards the Dewalt for torque and replaceable brushes.
