Default Tire truer questions

I have a Hudy 12v manual truer, and have a few questions.

Firstly, there is a very feint vibration coming from it when I turn it on. It's not enough to be a problem, but not sure if it's normal.

I noticed that when I skimmed some wheels down for fitting new donuts, that there is still a minor bit of foam on one side of each of them. This points to either out-of-true rims (Jaco), or a bent truer shaft (which might explain the vibration).

The other thing, is do these have user-replaceable bearings/bushes?, as that was another thing I though may be causing the vibration.

Any help is much appreciated

Hi mate

When you say a bit of foam still on the rims was it all the way around the wheel and if so one end ? If this is the case could it be that if there is a option to cut camber into them, it may not be full square to the wheel therefore not taking it all off. Thats all i can think of really.I have the 3 racing auto one and if its anything like that it would take a massive force to bend the shaft on it.

More than likely the wheel is slightly out of true. Any time I'm taking old foam off a wheel to remount donuts, there's always some foam that has to be taken off chemically, or with a sanding drum on a dremel.

Short of a machined OD wheel, you're not going to find perfectly round wheels. As all the wheels out there are molded, you're going to find they're all out of true to a degree.

As for your vibration, I would start by making sure the arbor is seated fully on the motor shaft, and that the pinch bolt is properly tightened. Then I would remove the arbor nut and see if the vibration is still there.

Just about every arbor out there has a bit of play in the threads on the arbor nut, so the arbor nut doesn't always tighten up square, whether you have a wheel mounted or not. That's probably where any noticeable vibration would be starting.

Thanks guys. The left over is full width, but only 1/3 of the circumference, and it's only about 1mm deep, which points to the wheel being the problem. I'll check the arbor, but as mentioned, it may just be a bit of slop.
The tires are still trued well, so that's the main thing!
