SCC Automotive Training: Hunter GSP-9700 Wheel Balancer

[@320466]

i will never use this machine in my life yet this video was quite informative, Thanks for sharing. Greeting as well.

[@curtshumaker5768]

Relative to Smart Weight - it's fantastic for a shop owner and most of their customers. The rounding algorithm used works - saves the shop $ on correction weight and satisfies most customers. If you want the best balance, turn it off and adjust the "blind" to get the rounding to the lowest option possible. Then, use 3m weight that you cut to length. Add in a calibrated machine and a competent user and you will have a well balanced assembly.

Gracias hermano estoy seguro que si salistes un poco pedo gracias por compartir todo chingon y chido

[@SuperAsianDude1]

i wish all tire shops were as directive as this.

[@justintarvid]

Direct?

[@alexyon_etc]

Please confirm a better run out is my issue and many thx for this great video which made me better understand about the wheel vibrations (am an engineer but still) which I have been dealing with for more tha 10 years. For the last10 years I have used a chain-shop having Hunter Road FOrce but many times I still had vibration issues like now.

[@patswazent]

fwiw you can do "bare rim measurement" and apply last roadforce/tire data once back together. this will allow you to measure outer lip accurately and do roadforce the correct way.

[@SuperBorg1]

3 ounces of weights seems like a lot for my small tire. My 15 inch new tire also had 16 pounds of road force and vibrated at 70 mph. now they order me a new one since my steel rims were true.

[@curtshumaker5768]

I am glad to see you address the issue of centering. You can balance an egg, but it will not roll smoothly down the road. If the wheel is not centered, you will never obtain a true, accurate, balance.

[@mvalentine5174]

I sometimes use a cone on the back side and front side to ensure my centering is true offset each other

[@richardwrynn824]

Old school says that all that rust should be wire brushed away, and leaving all those rocks in the tread doesn't help matters.

[@steadyeddie7453]

Good eyes Richard. I noticed the same thing. A hi-tech machine that can do super accurate work and he left rocks in the tread and rust/corrosion exactly where the centering cone sits. Gotta start with the basics.

[@zipzap4706]

I noticed that as well.

[@aviography]

Same here, and I am not even in the business, just a “car guy” working in aerospace business, landing gears specifically.

[@alexyon_etc]

I wanted to know what a normal value is for the road force...I just got 4 new wiunter tires installed by a Nokian dealer using Hunter Road Force and values I was told they had were 7,7,8 and 9. These numbers seem OK I mean low enough but I still have some vibrations in my car above 120km/h (front and rear). Does it mean the balancing is off for some of them causing the vibrations or does they need FORCE MATCH? Other tires I had with up to 14LB road force values had to be rebalanced (or maybe they did FORCE MATCH but di not tell me) to get rid of any vibration.

[@ericboisselle1145]

If you balance a wheel and it comes out ok, take it off the mount and try it again should it be ok? my tire guys says it impossible to remount and see if it is still ok. Thank you for time you took to explain all this

[@pdeblois1880]

I’m surprised you left rocks in the tread.

[@Headsup9550]

Since the measurement for the outside of the wheel lip surface is essentially just a way for the machine to know the width of the wheel (the outside measurement function became available at the same point in time as we no longer had to measure the wheel width with the calipers) , is there a way to enter the width of the wheel if it happens to be stamped on the wheel somewhere?

[@LoveNoThotss]

Thanks

[@georgemack666]

what did he doulble tapp?

[@rickwichman8742]

I purchased a new tire balance machine and I balanced a new tire and aluminum wheel and set it in the rack and when the truck came for installation I put it back on the balance machine to show the owner it was balanced, to my surprise it was asking for 3.75 more weight for to be balanced ? is that normal ? should it not have still been balanced, thanks

[@jardavomacka7182]

the front is fastened over the cone so that it is not scratched

[@ehsannemer1900]

Thank you very match

[@billyeminov5549]

from where can i buy it Hunter machines?

[@fromisheon4867]

There are ture shops that put the cone from the outside. Is that a method?

[@talhahussain3985]

I got this done at my dealership and they said my tires can't balance because the tires are 6/32. Is that right? You can't balance tires with thread life at 6/32?

[@marcustangent]

Hi! I gotta ask. I bought a new machine its a bright cb66 and i tried spinning a balanced reserve tire thats never been used but somehow i got a reading of 5 & 10 and the next spin was 10 & 20. Its my first time using a wheel balancer. Where do you think i got it wrong???

[@mvalentine5174]

Consult with the manufacturer of your machine and get on phone with Tech support and let them help you, all machines are not the same

[@UuganJasper]

Probably it's the centering issue..

[@Isaacpsalms]

I have question for you Our hunter balancing machine have error When you apply loadforce After spinning the time its says Too much speed And stops

[@trampanaguiton1448]

After vulcanize the tire, you' ll need to balance again the wheel??

[@mvalentine5174]

You should spin it anyway to check the balance after a repair, sometimes you may have to rebalance, especially if you had to pull outside weight off

[@dakotawhite84]

Could u tell me why the top laser that runs across the tire to showe u Wher to put the weights don’t work on mine? Bottom one works fine just the top one and i can’t find anything on it

[@mvalentine5174]

Ur laser could be burned out, contact authorized service center, u need that laser

[@Isaacpsalms]

What may be the issues

[@foulematouibrahim964]

Hello I hope you are well I do tire balancing parallelism I would like to work with you one day

[@huzaifaadamyusuf1972]

✊

[@emmcee476]

Is there a way to do a static balance with this machine?

[@mvalentine5174]

Yes

[@mvalentine5174]

That's usually more so for high flotation tires (31, 33s, 35. Etc) and aftermarket wheel assemblies and anything above Passenger metric tires

[@moitan434]

I just want to understand, because every I boughttire alway charge the wheel balancing

[@soitruong8878]

Chỉ bánh xe hơi mới cân bằng động thôi. Xe ga xe số mấy khi hoj làm đâu.

[@leisurehobby9980]

Any such advance system which can measure out of balance of the spinning wheel of under 10 grams from say a big 15+kg wheel + tire and that road-force black roller measuring differences of tire wall response, is only as good as...... how accurate the initial calibration and the proper scheduled calibration of all the sensors. Wheel bearing play in the main spindle itself can wreck havoc. Sometimes I wonder what self check feature an owner/shop of this Hunter 9700 must do at least per week or per XXX amount of wheel balancing work. Then come Hunter's HQ certified tech coming for another scheduled major calibration. No such equipment like this can do well all the time without proper calibration. Owning a few high sensitivity sensors in my work, without proper scheduled calibration is a big NO. How do we as customer knows that a shop has done proper calibration on their 9700 ?

[@aviography]

Excellent point, I went to a new tire shop and got a set of new winter tires, noticed vibrations on highway speed a week later, went back to shop who said they had another customer experiencing similar issue, asked me to come back after Hunter technician recalibrated the machine, the tires are rebalanced as minor calibration issue was found, now my tires are 1 lb, 6 lb, 19lb and 26 lb, still experiencing a bit of vibration even though much better than first time, but tire manufacture rep now claims to tire shop 26 lb is acceptable, so now I have to contact tire manufacturer myself, not a happy customer at the moment.

[@leisurehobby9980]

@@aviography I just done 4 cars on Road Force. Indeed, its difficult to get all tires to 100% same good value say of amazing beauty of 1 Lb. It is just how manufacturing tolerances are on street tires. In fact I threw one new (3,000 mile/5,000KM) tire one out due to 100Nm ( 73 lbs ) value after troubleshooting transmission mount, drive shaft coupling and other potential vibration contributing values. Now the car rides much better. Bad roadforce variation vibration if you measure with accelerometer : is different from out of balanced condition which is more like left-right shake ( X axis ), while roadforce variation is up/down sensation ( Y axis ). I doubt you can claim a 26lbs variation. My other tires are average 20-40 NM ( 14-29 lbs )...sad I know. Michelin Pilot Sport 4. 255/40-18 rear and 245/40-18 front. 50nm or 36 lbs and above is indicated as RED ( bad ) in hunter 9700. If you are using off-road type tires, forget it, it is almost certain roadforce variation is high, that is the nature of the tire according to the tire tech where I done my roadforce balancing. Drive safe

[@leisurehobby9980]

I forgot to add, I also measure out of tolerance for the tires and rims/wheel, all good.

Dommage qu'il n'y a pas une traduction en français ❓

[@mseiler34]

How much is this machine?

[@mvalentine5174]

Generally 15-20k roadforce machine are top of the line hunter machines

[@davidvdheijden3970]

As a mechanic I say its way to complex to balance a wheel! We have a Schenk balance machine for about 35 years never had isuses with balance a wheel! The biggest problem from this kind of machines is the horizontal axle!! In industries the always work with vertical axles this machine hunter en all of others clones the are not good build, what do you think when the roll make presure on the vertical axle more difference you have and thats wat you don’t want when you balancing!

[@user-rr7je8iw3b]

This machine is way better than the Coats 1250. The Hunter GSP9700 is easier to operate and learn.

[@dilipmakwana4124]

Job for me I am wheel alignment and wheel balancing technician

[@Jersey4x4]

why would you use a strip of 1/4oz weights and spread them out over a large area and not use a heavier weight and place it where the machine is telling you. You are causing inaccurate readings

[@jonathannonan7211]

Wrong procedure...before you make balance with road force or standard balance the wheel. U need first to centering the wheel that's the first procedure.

[@4r1ffster70]

Customer need pay more to use it...

[@dabell12]

Customer need pay more? ... that it wont happens, customer shopping around because no body have the cash anymore, very expensive machine it wont produce you more income. is no money to being made change , selling tires , even repair shops having hard time staying in business.

[@matthewharhai4039]

Worth it. Excellent balance.

[@vuqarqasimov5866]

HoV much Machine

so complicated

[@hiimholdin2397]

To much

[@scottdiamond74]

Don't waste your money. This machine does not do what Hunter claims.

[@aviatorej79]

Oh really? If that was true then how come almost every OE requires it??

[@jojo-ck6dv]

very complicated machines, don't waste your money,

[@jonathanwilson6466]

Complicated? Our shop has the newest version of the Hunter and I taught myself how to use it in about 5 mins after watching this video. and I'm an ADVISOR. Im certainly not the sharpest knife in the drawer either. This thing is idiot proof

[@sjgerber]

@@jonathanwilson6466 and it works

[@mvalentine5174]

Have you used one of these machines?

[@fdkfskfkvmk441254741]

​@@jonathanwilson6466 Question is, have you see your investment back? Hunter are some expensive pieces of equipment.

Not to real shop owners. Sorry your cheap ass can't afford it.
