what is this? snap on

[compyello]

High rpm motor, scrub brake, any ideas?

It's a wheel spinner, you know for when Ferris Bueller needs to remove a few miles from the odometer.

Just a heads up!!!
It ends tragically when used

That is part of a on the car wheel balancer. Hunter made them and they worked great but it's been about 30 years since cars were made that you could use them on. Computer wheel balancers took over for them. They were great for balancing tires that had out of balance brake drums behind them.

I am just suprised at the rpm of this motor.

Yeah, they could spin a tire at the = of 70 MPH. Lot of HP there too.

I have seen this spinner work just once or twice. I was intrigued and asked what the mechanic was doing, and was told that this was called "Dynamic Balancing" as compared to static balancing, the type of balancing where you put the tire on the pyramid type machine.
It was interesting to see how it worked but at the same time kind of scary how fast the tire was spinning.

Thank you to those who helped me with figuring this out. Now, how does it work? From from what I am finding it is a guessing game on where to put weights and how much weight. Is there a method to using this?

Did you read the link I provided above? Straight from the horse's mouth.

 

[compyello]

so you spin it on the car, take it off and put it on the balancer, put it back on the car and spin it again?

 

[compyello]

Sorry zkling, I see it now. It states " helps you sell your wheel balancing service" so you can spin the tire and show a customer, then remove it to balance

 

[compyello]

My first though was on the car balancing

There's a unit that clamps into the wheel that has weights inside. There are four knobs in the center. Two of them add or subtract weight and the other two change the weight's position around the wheel.

To use it, you spin the wheel up and add some weight, then move it around the wheel until you find the spot with the least vibration. Then you add or subtract weight to find the weight with the least vibration. The amount of weight and location are displayed, and you place the weights on the wheel.

I know a guy that still uses one of these AFTER using a state of the art computer balancer. He might be fine trimming with a 1/4 ounce. He balances Bonneville car wheels.

Fellas in the truck frame and alignment shop had a biggen like that. That's a tool for zinging rocks around the shop, really not for shops with gravel driveways.

My dad's dealership had one of these when I was growing up in the 70's, there is a pickup you place under the car on the A arm that triggers a strobe light, spin it up and watch the wheel with the strobe. Strobe fires when the lightest part of the wheel assembly is at the top, use the valve stem for reference. Will balance the entire assembly, it doesn't get any smoother than this guys. We even used it on the newfangled front wheel drive cars, I just sat in the car and ran it up to about 70 while John watched the strobe. It was really good on the front wheel drives, balanced everything all the way to the transmission. We could get them as smooth as glass.

 

[Scimonetti]

How many rpm is it?

 

[compyello]

For sale in the classifieds. Scimonetti, I will check on the rpms but they were high

 

[royesses]

I used one in the 1960's. Jack up car, support under frame. Place magnetic pickup under lower control arm at ball joint. Place a chalk mark on the tire. Spin the wheel and watch balance meter for how much weight is needed and note where the chalk mark is positioned while illuminated by the strobe. Then stop spinning the wheel, turn wheel so chalk mark is where the strobe illuminated it. At 12 o'clock is the light point needing weight. If more than 2oz. split the weight into 2 and place one inside wheel and one outside wheel at the 12 o'clock position for dynamic balance. Sorry if this is a little terse, I'm getting old. You can also place the magnetic pickup against the brake backing plate to check dynamic balance. For rear wheels jack up and spin but keep the rpms down to no more than 45 mph on the speedo.

That wheel spinner is STILL up on sioux city clist, probably for good reason

 

[compyello]

you should buy it

 

[d430]

Maybe you could make an engine starter for your Moto GP bike?? LoL

My guess was it was a starter for 2-stroke race bikes. It would probably work great for it.

 

[Milton Shaw]

One caution on bike starter. If used from the rear the motor would be turning backwards. great for trick riders but would give most people a bad crick in the neck. One speed forward, 4,5,6 reverse speeds. LOL... Great for checking wheel bearings as they really roar at the speeds those turn a wheel.

 

[compyello]

sold

I use one regularly on modern cars, it's a fast easy way to check wheel-bearings or if you need to locate a rotational noise. Wish I'd seen this in time, $100 bucks was a steal!
