how to clean stator and flywheel

15 Mar 2021

Build a charger (simple). No since removing the flywheel if the stator is working OK. Voltmeter on dash does not climb with the rpm's. It's not as harsh as brake clean or carb clean. The place you choose should be free of paint and debris, and I recommend sanding it. now the only number that is not making sense is the 10vac off the stator. 2.to open the flywheel to see the condition of magnets , it should ΝΟΤ moved!!! How much time can you ride between rides? Drawing too much current from the stator could have been a result of a short within the regulator assy or possibly too great an amperage draw thru both the stator and regulator. Start by going from let's say, the battery wire you're using to the resistor. Expand the branch. Please forgive the sloppy diagram; I made in paint. 1 year ago, Can you take A 8 call magnesia and change it to IN call magnate or will it hurt the bike it's A150CC, Answer 2 years ago Be sure to get it nice and deep in the bore so that you have more thread to pull against. I just removed my flywheel, stator,cap, rotor, but not my breaker point assembly (can't find the anti-reverse spring). In a few weeks I will be consolidating this page and removing obsolete material. I like to take the flywheel and run it over the wire brush wheel on my grinder. Maybe you have already done this but take a hammer and pound on the top of the puller bolt. It functions like the magneto winding." Good luck and get the elbow grease out. Symptoms are often worsened as the engine warms up. Set the points gap to the correct value with the Flywheel in place. The voltage readout should be whatever you're using, but we're concerned about the sign here. Use a 3-M scotch brite pad to clean it up. For those of you who don't know WD stands for water deterrent, great rust prevention! So after I wired everything, I get power to the spark plug wire but no spark. The second and much less likely cause of a system failure is an issue with the contact breaker. On cars and motorcycles the metal parts of the engine are in electrical contact with each other,  which causes them to make up one large electric terminal. You can go to place where you can get your stator rebuild in about any town, or rebuild it yourself. If for some reason the system isn't working, it is almost guaranteed that there is a open or discontinuous circuit. Whether the rust is inhibiting a spark or not, it's always wise to maintain your parts. If it is still off do it again until the spark occurs at the correct place. Depending on your model this may be the left or right cover, and may also be holding back oil. You could find a way to wire the lights up to the battery but I won't be explaining that. 4. If this doesn't work, try slowly turning the engine over to ensure the contact breakers are in the closed position. Make sure all connections are free of moisture, tight and use a small amount of dielectric grease. The cost of a new stator can be hundreds of dollars. Once you have the clips on, you'll need to figure out which lead is positive and negative. You have to know. I am trying to remove the stator rotor to replace the stator assembly on an D1E41QMB engine. This may be overkill, but it won't hurt anything. on Introduction. Turn the voltmeter on and set it to AC volts. The process is then repeated until you find a branch that is an open circuit. Sheared those three bolt heads right off leaving my stator, and mag cup ruined. 2. Create a Battery-op Ignition System for Less Than $50: The cost of a new stator can be hundreds of dollars. There are several methods for charging the battery. attach a chain to the flywheel and attach the other end to a good truck. This solution completely bypasses the stator by using a 12 volt battery to power the ignition system. Congrats! Good luck and get the elbow grease out. Use kerosene or fuel oil if necessasary clean that off with nonflamibile brake cleaner. Alternatively, you can lock it this way: remove the spark plug and feed wire or rope down into the cylinder. (For electronics people, it's the positive terminal of the secondary coil. On this particular circuit, the resistance should be somewhere around 5 ohms. Won't eat the plastic parts in there. Space Saving Expandable Table for Tabletop and Board Games, Plug-in Round Wood Wall LED Lamp | Portable Circle Socket Plug Night Lamp. Purchase a charger designed for charging 12 volt batteries. Then check the timing. It's not as harsh as brake clean or carb clean. I found that the (older) canister type ignition coil designed for cars work for this application and don't get hot or blow up. Make sure you turn the switch off while not running or else the battery will drain. If you put the 2 ohm in the circuit you may not have a spark. Just make sure the ignition coil and the capacitor are near each other. F̶o̶r̶ ̶c̶h̶a̶r̶g̶i̶n̶g̶ ̶a̶t̶ ̶r̶o̶o̶m̶ ̶t̶e̶m̶p̶e̶r̶a̶t̶u̶r̶e̶,̶ ̶i̶t̶ ̶s̶h̶o̶u̶l̶d̶ ̶b̶e̶ ̶b̶e̶t̶w̶e̶e̶n̶ ̶1̶2̶.̶9̶ ̶a̶n̶d̶ ̶1̶4̶.̶1̶ ̶v̶o̶l̶t̶s̶ (The voltage of the power adapter is listed on itslabel). I would cut sections off a spool to the required length, then sand the insulation off the ends and attach alligator clips. If you clean all the chain lube gunk around it you will see the mount bolt holes better, perhaps, and see how the device lines up. I removed the whole stator just to have it out of the way and make things easier. If the reading's sign is positive, then the leads on the charger directly correspond to the meter's test leads that they are attached to. Before removing the flywheel I would check the output voltage from the stator. As mentioned before the guides for regular 12 volt batteries don't quite apply because the smaller ones are of a different construction that produce 13-14 volts, so I have no reference range for charger voltages. This means that the numbers in the paragraph below are incorrect for smaller lead acid batteries. This will prevent wiring from physically coming apart, as well as prevent it from losing electrical contact due to corrosion. Sometimes it is necessary to use the flywheel holding tool to get the puller nice and deep. With the flywheel off, we've finally gotten to the contact breaker points which is what we need. This wire should attach to something secure, like a cooling fin, head bolt, crankcase, etc. Tips: -Use hot glue to secure components and wiring where you want it. Share it with us! This wire has to be directly connected to the contact breaker inside the flywheel. The series order of the pieces doesn't matter, and can be done however is easiest for the space available on your particular machine. Once this is found, you know the problem lies in the most recent addition to the branch and can fix the connection issues. Soak in WD-40 a day or two, steel wool what won't come off with WD. Shippping worldwide and daily! Wire the battery to be charged to the car battery, positive to positive, negative to negative, as shown in the diagram. To make the coils bind together as a single mass thus preventing vibration that can rub off its electrical insulation and second, to prevent oxidation of the steel lamination. Once the cover is off, remove the fasteners you see in the picture above, clean with some Brake Clean or like solvent, clean the hole the screw goes in to. Using the voltmeter function of your multimeter in the proper voltage range, attach the leads of the meter to the alligator clips on your power source. Make sure you route it in a way that avoids moving parts. When the amperage drops significantly from the initial reading it's time to disconnect. the oem is 550$. 6 on the South face and 6 on the North side Next step is to clean … This is the easiest and fastest method, but expect to spend $30 minimum to buy a unit, and size wise they range from a shoebox to a suitcase. This is the lead acid type used for car batteries. I got mine for about $10 on Amazon. Mine had 2. I bought this no name one off Amazon for about $15. As evident from the diagram, further explanation is needed to explain how to wire the "engine" in series with everything else. For this method you will need the power transformer from an appliance you don't need anymore. @tarylfixesall I devised this system when the stator on my Honda XR-100 got so weak that it couldn't power the spark plug, preventing the engine from running. Subject: Re: Flywheel/Magnet /Stator problem Briggs 14.5 hp Sun Nov 20, 2011 11:12 am well dont u need all the mags and the stator to keep the battery charged and work the lights. Gets the whole outer flywheel surface shiney clean. If you put this wire in the wrong place on the contact breaker, it will directly contact the first wire and bypass the switching effect of the system. I used to use the old style b/c the updated ones are worth more until I had 2 on my personal machines fail within 2 weeks of each other. FYI: The stator coil generates the power for the spark plug and other accessories on small engines  Without a stator there would be no spark at all, meaning the engine won't run. The only reason the wiring passes through the engine is to reach the contact breaker system. Bad Stator Fix--Don't Buy a New Stator for Your Engine! That is just plain nasty! i know this is an old post but ive come across something i hadnt seen before with a villiers flywheel. Im trying this on a 1986 yamaha it200. or put the bike in gear, hold the rear brake, and loosen the flywheel … I've always wired the capacitor to the points, Question the rest is pretty intuitive. I used the one that was one that was part of the original ignition system on my dirt bike. There is a little bit of corrosion, the white crusty variety, and minimal surface rust. Pulled the stator cover to discover the mag cover only had 3 out of the 6 bolts in it. You could even use a hybrid approach to power the ignition with the battery and the lights with the stator, but once again you would have to figure it out on your own and rewire the stator after disconnecting it from the ignition. That's your master cylinder again. The stator goes back on engine with stator wires disconnected right? Flywheel-mounted trigger The ignition winding is separate from the other windings on the alternator stator. Reply With the flywheel off, you should see something like the first picture. In our club in Greece , we have about 10-15 FZ1 with broken flywheel , and in different locations other so much and models as R6 , R1 with the same damage!!! someone help. The third is the contact breaker attached to the engine. The most difficult piece to mount was the battery. I  previously tried using two universal coils  intended for small engines. Lastly, a  short circuit could cause the failure of the system. The flywheel on a John Deere mower serves as a timing device for the electrical spark flowing to the engine's cylinder. ***See the next page for an explanation of how to wire the system to the engine*** For those of you familiar with electronics, every component is arbitrarily wired in series without regard to polarity. With the meter hooked up to the whole system and giving a closed circuit reading, slowly turn the engine over. Question The contact breaker switch will open (turn off) at least once, sometimes twice per combustion cycle. While a stator is dying, it can produce a weak spark, causing the engine to miss or run poorly. Give battery full charge and she runs great for awhile. These are cheap and a good tool to have around the house. If you're worried about overcharging, you can unplug the charger after several hours. Before removing the flywheel I would check the output voltage from the stator. Any resistance value displayed means the circuit is continuous or "closed". I ordered the remover from a suggestion on another thread on how to remove the stator rotor. I bought a generic one off Amazon for about $18. A reading of 1 on the display indicates a broken, or "open" circuit. On my Honda I glued the components to the front of the frame. I am wondering if i should bring a power pack with me when i go on long rides. ... You may need to clean the connectors. The second picture is a contact breaker assembly removed from the engine. (This does not work for the capacitor which SHOULD register as an open circuit across its terminals)  If it registers as continuous, the problem lies elsewhere. Update 4/25/14: I've found that a charger producing 15 volts is enough to charge the battery in a reasonable amount of time. 1. In \"Taryl and Chuck Hill\", Taryl demonstrates how to repair the flywheel magnets on a Kohler Engine (or Krohler as Taryl refers to it). I recommend fastening all the components to the machine first, then wiring them together after in the most convenient way. Is this most likely the stator or the voltage regulator? This is where the spark plug wire will connect. The tool actually screws into the hole in the center of the flywheel. on Introduction. Be sure to check your starter seal, and stator grommet seal. I usually use an oil based solvent like wd40 or diesel fuel. To test for this, you will need to use the resistance setting on your ohmmeter/multimeter, in the 200 ohm or lowest range setting. Assuming you're like me and don't want to run the car just to charge a battery, you could even tuck the battery somewhere under the hood, cables hooked up, and just leave it there as you drive about your normal business. My dirt bike had the hold down style so I bought a $5 toggle switch from home depot. I usually use an oil based solvent like wd40 or diesel fuel. The stator on a riding mower is located on top of the engine below the flywheel. I IMPLORE you to take the cleaning step! Sheared those three bolt heads right off leaving my stator, and mag cup ruined. -Rubbing alcohol/acetone can easily remove hardened hot glue if you make a mistake. 1 year ago, Can you change A 8 Coil O not magnesia and change it to A10 call magnesia on a 150 CC will it hurt it, 5 years ago If you are concerned about draining the car's battery too far while doing this, you can run the car during the process, in which case the alternator will be the power source of the charge. Prior to swapping the regulator, run a quick jumper wire from a non oxidized or non-painted section of the regulator case directly up to the battery (-) negative terminal. Ignition coil: This needs to be a fairly heavy duty coil. $0-100. Step 1. I prefer to wrap this wire around a bolt and then tighten it. This wire can be attached to any conductive part of the engine assembly. Electricity will always take the easiest path, so if given a chance to bypass elements through a better conductor, it will. You can lock it in place by using a special tool. I have a '72 Johnson 85hp. As far as washing stuff like that off, I usually use a paintbrush in my parts washer (diesel fuel as low-buck solvent, lol) and chase that with compressed air to dry everything and blow off the remainder. Make sure the meter is in the 10 Amp or similar range. I ordered a flywheel puller from partsforscooters, but cannot get it to work properly. There are two magnets in the flywheel. (The alligator clip attached to the red (positive) test lead is positive, and the clip attached to the black (negative) test lead is negative) If the reading is negative, then the charger leads are opposite from the test leads they are attached to. -Remove the flywheel. Also seal around wires and check small rubber plug at bottom where RZ neutral wire would be. If you use a higher voltage charger, the process may go faster, but you face the risk over damaging the battery because it will not stop upon completion. There is a little bit of corrosion, the white crusty variety, and minimal surface rust. The dremel was used again to rough up the glued side of the magnet i.e. Anyway, what should I use to clean the stator with. Without the switching effect of the contact breaker, the spark will never fire. give yourself some slack so you can get some speed up before the chain goes taught. If you plan on charging somewhere cold, maybe a garage, see this guide as the voltage of the charger will need to be different for safe and effective charging. I hot glued the battery to a piece of wood, then screwed the wood to the front fender up through the bottom.
