  • Hudy tire truer acting up

    My Hudy tire truer is acting up. The motor pulses and the digital readout on my power supply shows significant drops in voltage with each pulse. It's not the power supply. I hooked that up to my Tire Razor and a few slot car motors and the supply works just fine. I also removed the o-ring from the Hudy motor shaft and I still get the pulse, so I know it's nothing in the pulley system. The Hudy motor must be dying. Does anyone have any idea what might be wrong with the motor and if it is something that I can fix without any significant skills, or should I just replace the motor?

    You could try cleaning it with a motor cleaner, And if that doesn't work, You can replace it for about $33.00 for SSC.

      Tried that Robert. Thanks. I do have a replacement around here somewhere. Finding it is another story.

    take a look at the brushes if it's an R/C car type motor. i've gone through them before. they're usually shunted.

      I just checked my Hudy, the motor is the same dia as an RS-540, the RS-550 has a longer stack. If it was me I'd be looking at a 35T RC Rock Crawler motor.

    Here's a link to Hudy Tire Truer motors on Slotblog. http://slotblog.net/topic/53729-hudy...acement-motor/

    In post #5, Triggerman replaced his with a Duratrax Photon Speed 2 motor. I replaced mine with the same motor, less than $14 and works fine. Problem is they don't seem to be available any more. Might find one somewhere. If not contact Triggerman, he's the guy who does the knob jobs on the Hudy Tire Truer and knows more about them than anyone and ask if he knows where to get one or what other motor would work.

    If you have a local bricks and mortar hobby shop that does RC cars just drop in and see if they have any "take-off" stock motors in a parts bin somewhere. It's a 540 type, should be able to get one for about $10.

      It's a 550 not a 540, you don't want a screamer of a motor you're best going with a slower high torque jobbie, 35 turn at the most, maybe even a 45T

      Kevan,
      OK, the Hudy truer I recall seeing could have had the 550. It's been a while since I was in RC, I can't recall how the box stock Mabuchi 540 is wound - 35 turns sounds about right.

    If the voltage output of your power supply keeps dropping then the motor is using too much current. Possibly the commutator has gotten shorted because of motor brush dust in the slots. Sometimes a few shots of contact cleaner with the motor running will flush out the dust, otherwise you would have to take the motor apart and use some thin plastic to scrape out the slots. It also does not hurt to oil the bearings once in a while.

      I think it is the same motor that comes in a Barbie Jeep
