Removing the stator cover tip

[Anonymous]

talk to scotty, he might loan out that big A@$ battery to smak the stator cover off :lol:

last year when i was putting on the polished cases i thought that a wire was catching in the cover. i asked my brother for help and by keeping the thing straight and adding some woden spacers, I finally got it to the point where i could get a good grip on it.
:?: A Magnetic field in the jumper wires. we couldnt get one unless there was a load in series with the cable. I think. Oher wise it would be a dead short. i wonder if using one of the cables(after it is coiled and wraped around the stator cover) in series with a lit lamp cord would produce a low frequency flipping magnetic field and have some effect on removing the cover.. COME ON HAP INPUT PLEASE
WOULD A DC LOAD DO IT BETTER???Maybe by changing the polarity of the DC load to see if it has an effect in one way or the other??

Well, I am a physics and electrical engineering major. So i guess I'll take a crack at this.


First of all you have to understand the theory of electromagnetics. The B field (magnetic) opposes the electric field AND the direction of propagation by 90 degrees. If you take your right hand and point your fingers like you did as a kid when pretending to shoot a gun, and then hold your middle finger perpendicular to that, you have what we physicists call "The Right Hand Rule". Your middle finger is the direction the fields are moving through space, your thumb is the electric field, and the index finger is the magnetic field.

Maxwell's equations unite the properites of static and time-varying waves into just 4 equations. The one we are interested in is the one that says "Magnetic field density is equal to the current in a wire time the number of turns in the coil". The magnetic field then would be going through the center of the coil according to the right hand rule. In other words, if you wrapped the cable around the stator cover a few times in the clockwise direction and hooked the end of it up to the negative terminal (so the current flows clockwise) the magnetic field would be going in to the stator. (it actually loops all around the wire, but the net sum is a straight line going in to the stator)

Now here is the problem with using this to pop the cover off the stator. In order to create a large enough magnetic field that would compare with the alternator magnet, you would need to either have many, many turns around the cover with very fine wire and/or have a very large current. You are limited on that since a large current implies using large gauge wire, and the larger the wire the less turns you can have around it.

Give it a test at home - take your motorcycle battery out and get a nail, wrap some wire around it and see how much it can pick up. get a bigger nail, bigger wire.. you will see that the magetic force decreases. Increase your current, you will see it get stronger. Wrap more turns around the nail in the same length, it will also improve.

From what it seems at first assesment, one or two turns definatly will not be sufficient to oppose the magnetic field of the alternator magnet. The current from the battery isn't going to be enough either. Sure, peak amps might be around 230A, but you can't make a magnetic field with somethign so short-lived.

Be careful when shorting leads together and such - remember these wet-cell batterys can explode and alse DO put out large enough current to do harm to you.

i think a little poket screwdriver and a hammer to get the cover opened up a bit then use a couple of large screwdrivers to get the thing off, sounds like the safest way to me

i use a 2x4 and a hammer... position the 2x4 on the cover near the starter (there is a spacer towards the front of the bike) and give it some taps. Always shakes it loose for me after a few tugs.

Careful not to mash the mating surfaces, as they are aluminum. It's very easy to do. :?

I dance around the bike during a full moon naked, give offerings to the valve stem gods, then lightly tap the cover all the way around and pry it of with leverage at the tab located at the bottom of the cover. Once it is off, I let out a war yell and skip down the road in front of my house.

you guys are all losers, other than the physics guy who is not a loser but none the less did not understand me. connect one lead, both sides of the red jumper cable the the terminals of the battery. one red goes to positive and the other red goes to negative, yes this creates a short but jumper cables are high enuff gauge that they will not weld for a while. a couple turns off the jumper cable does work. the battery might not generate enuff current to demagnitize a fresh stator but if u leave it off the battery over night the electrons will eb just into the surrounding air thus lowering the magnetic field of the stator, i too am a physics major. just try it guys

 

[redliner1973]

well maybe were not the 'Losers' here after all. As you can see from all the posts' here, No one could figure out you illustrious directions so be wise on who you call a loser.. :evil:

you ar still way off base. and if it worked for you without exploding the battery it was dumb luck. that wasnt a tip it was a sabotege. any one with the slightest knowledge of electricity would never do an uncontrolled thing like that. You explanation was as poor as your idea and you suposed joke "MAN"

try this and maybe it will work

Bigdadd63 (6:09:59 PM): Just put the bike on your jack so you can turn rear wheel in 4th gear and when magnets get in between rotor it will come right off
Bigdadd63 (6:10:37 PM): between stator!

 

[Anonymous]

yea that might work but my method works 1 because it worked and 2 because i got a from a trust worthy smart source. as if im really trying to kill all of u, why would u put it in 4th?

 

[Anonymous]

in the higher gear you get the same effect when pushing the wheel as you wold when the engine is trying to push the bike when in first
. I know he said fourth instead of fifth because he and i were bred on bikes with 4 speed transmissions.

I'm not worried about welding the cable to itself...I am worried about welding the cable to the battery terminals and blowing up a battery. Also, a stator is not magnetized...a magnetic field from the rotating magnets on the rotor/flywheel causes current to flow in the stator until it becomes flux field saturated. A stator just out of the box has no magnetic properties.

The physics major made some good points but while Maxwell's equations are applicable here you also need to include Gauss's law to fully explain the process. They both involve vector forces using three (five, really, when you jump into the deep study of this stuff) partial differential equations involving gradient, divergence, and curl (no joke) that are both confusing and complex. I doubt seriously that you have studied this area enough to fully understand it. I spent a good portion of my engineering degree studying this stuff and still get very confused by it at times. A good reference guide is "Fields and Waves in Communication Electronics" by Ramo, Whinnery, and Van Duzer and published by John Wiley & Sons Press.

If it worked for you then I am glad...I would like to see it demonstrated in person before I attempted it on my bike.

Oh yeah, a bunch of guys used to call me a loser in high school because I was a geek...they work for me now.

i have a great respect for anyone how knows what they're talking about and hap you definitley do. this is my second year of physics and we're in the process of learning about thermo dynamics, conductivety, heats, linear expansion, we haven't gotten to this stuff yet. but this tip was given to me by my physics teacher and he definitley knows what he's talking about.

I tried to express that in the 5th response to this post. For the record I wouldn't short a battery out like that either. I've only had to remove the stator cover once in seventeen years and it wasn't that tough once the seal is broken.

Do you know how to ride your bike ice109? :?:

Here are some tips, first you you rev it up to 12.500 rpm with no gear in, for a couple of ours, after that it becomes 120% more power. :evil:

After that excercice you could speak to your grandma and ask here for some more tips. :evil:

 

[earlfor]

AS my tag line sometimes reads, in theory, theory and practice are the same, in practice.....................
If I accept that the idea will work, my next consideration is, is it safe to do so? In practice, I do not think it is a good idea to short a battery with a heavy guage jumper cable because the risk of an explosion is too great.
I am wondering if your teacher owns a motorcycle and practices this method.
