Great video, great editing. I don't feel like a second was wasted!
My brother restores old ACs. He tears them completely apart to paint, lubricate and check bearings. He buys new gaskets, seats, mufflers and puts in new wiring and gauges but I don't think he'll rebuild a mag. Thanks for this, great job!
Great video. I am new to the A-C Universe and look forward to more helpful, step-by-step instruction. Thank you!
I am about to tackle my first magneto rebuild. After watching your video, I am confident I will be able to do this successfully. Very good presentation and it's nice to see a young lady involved in keeping these old tractors in the fields! Keeo up the great work!
How could you not love this Woman. Terrific instructional video.
Nice! her hands show she is really a mechanic and truly works on stuff. Awesome! Sending this to my daughter.
So cool to see you back at it! Great video and thank you for helping keep these old tractors alive.
Nice video. Great lighting and camera work.
SO glad to see you back! Another great video!
I'm getting ready to rebuild one of these on an old chalmers I've never had a chance to tear into one but I feel much more confident after watching your video thanks excellent job 🤟🚜
Nice job Rachel! Looks like a professional production....
This is a great video. You make it look and sound easy to rebuild a magneto. Keep up the good work!
Lovely to see a knowledgeable young lady well done. It's easy to see you know your job and also enjoy it. 👍👍
Excellent job of pointing out the parts and reassembly. The only step that was missed, was when installing the Mag back on the tractor, is to make sure that the rotor is pointed at the pickup inside the rotor cap for which ever cylinder is at TDC of the Flywheel, other than that it was a great video and I haven't seen any videos this good on rebuilding from beginning to end. 👍 😊
What a great presentation, very professional. Thank you!
Thanks for a great tutorial on the WD. You explain the details clearly. I could do this repair. Wish I would have seen this two years ago when old orange would not start.
Good job Rachel.
It was obvious to me , she has excellant mechanical abilities! I learned a lot .
Great video! I would suggest that when the armature is out, if you are not super-sure that the magnets are strong, get them recharged. Never a better time. Weak magnets were the main problem I had with my recently-repaired FMJ on my B.
Thank you for the new video. Great job.
Très belle démonstration , toujours avec le sourire .
Thank you for the videos! definitely enjoy watching and being able to easley understand. Young lady you are the real MVP
Well done
Excellent job.
Increadibly smart video! My tractor magneto works just fine now. Thank you! Good work!!
Great video, for a teenager she sure knows her stuff.
Well i'm glad i found this. thanx Rachel !
Great video for the FM rebuild. Make note, the F mark showing, does not tell you if the number one cylinder is on the compression stroke or the exhaust stroke and the F mark is not for static timing( use the C or TDC mark for static timing), but for using a light, while the engine is running.
Maybe you cover this in another video for actual timing of the magneto?
Very good and informative video. However, I would seriously recommend that Rachel wear eye protection when working on parts containing circlips, snap rings and springs. We only get one set of eyes. Thanks for sharing.
Thank you so much for your videos! They have been very helpful.
Enjoyed your video
Blessings To All Worthy Of Being Blessed
Great job, Rachel! I've been re-watching some of your older videos, and it's been interesting to see how you've matured, and how your experience is growing. Very thorough and well explained! I was wondering, also, if you are still doing auctioneering? Keep up the good work!
Nice video .
On an F163 and 162 you time the engine and mag to #4 cylinder. You did not mention timing the mag. I have a 2 cylinder Wisconsin on a 1947 Lincoln welder I lost my fire on it and the mag is similar with the gear on the cap. Thanks for the video.
Ad a Old Mechanic and I had work for many years on Alli Charmer farm tractors she us Excellent
Thanks for the video. Working on a ‘54 harley and couldn’t find any information on how the seal assembly works on the bottom of the magneto (Morris / Joe Hunt). Found it quickly in your video. Thanks!
Sharp looking tractor
I've never tore apart a mag before. You totally blew my mind away at how you ripped it down and put it together like a pro In record time. You totally have my respect and admiration. I think there are women out there that make better techs than men. The only problem I have is that you're so damn cute that I find it hard to pay attention to the tutorial lol. Thanks for sharing 😁
Super helpful thanks
Nice job. Next time could you show the press work, i.e.: armature and bearing removal/re-install. Thanks
is there any repair work that may overwhelm you? It appears to me that you would tackle just about anything. You are an inspiration to anyone that watches your series of videos, but I hope it does so for the younger generation such as yourself. You give me hope that all will be well when I take my leave.
Nice!Be carefull not to hurt the coil with prying against it with the screwdriver to remove the plate.
Magnificent.
Good job, from Hillsdale Co.
You are incredible. Do you happen to work on old wesconsin 4 cylinders.
I can't get over how well spoken you are .
Hey
Thank You
great job ! and very talented and cute host ;)
top video
david trollope : not a teenager.
Nice pro video
One way of testing a mag is put a finger on the coil and give it a spin with the other hand, you'll know if it works or not. My grandfather got me with that trick when I was young.
I have a 48 Allis C the mag has written on it that it was a hot rebuild. I'm not seen that before on what it means.
I have the same tractor that came with the property I bought, runs great for about 10 minuets until the carb ices up solid, my "M" doesn't do that, any thoughts?
That's a great looking tractor !!! Are you and your dad or ur husband in the tractor parts sales ? I love them old tractors where in Michigan you from up or lower I am from Wisconsin near Green Bay love your show!!!
Good stuff!
Everytime I take something apart then I replace the bearings if possible.
Hi Rachel,
Where does the larger black wire running opposite the condenser connect to? I have a FMX Magneto on a Ford 2N tractor and it does not have that wire. Also, even when my points are open there is continuity between them. Should the smaller coil wire, condenser wire and point spring all be connected on the insulating post? (I have new points, condenser and coil installed.)
Is the installation of the impulse spring the same on a Wico xh? Having a heck of a time, and I'm running out of curse words.
How do you figure out which way your magneto turns clockwise or counterclockwise?
Need more women like you! Good video.
I just bought a 1953 I think the weight or spring messed up some times it makes the clicking sound and some times it doesn't when I turn it by hand I already dismantle it 3 times and I noticed that when I don't hear the clicking sound there is no spark
Great video... Should you (Just as a good general rule of thumb) put the tractor at TDC before starting this job to be sure you don't mis- time the tractor when reassembling?
Probably a good idea to put the engine crank aligned with the timing mark before disassembly. I use a business card or the card from a cigarette package to set the points. Check thickness with a micrometer first. Card will not scratch the point surface and often feeler gauges may have a thin film of oil. Note: women were often used for fine work on engines in WW II. Queen Elizabeth as a teenage princess qualified as a "Driver/Mechanic" In the British Army.
I put one on a C, the timing mark is easily seen through a port on the rear of the engine. It is really easy to find the mark and you can also check to see if the impulse springs work so it isn't really critical to set the engine at TDC you can turn it until it is and then set the mag to where the points are just opening. The tractor I put the mag on had been messed with a bunch before I got to it. I am sure there is someone on here showing how to do it.
I have 2 issues. My Magneto is counter clockwise could you help discuss that way of timing it and also there is no fire mark on my Why will. So how do I go about timing it.. Thank you!
I didn't see the horseshoe magnet. I have an allis B with mag. on it. Is it, most people
don't worry about recharging the magnet .
anyone know is there a aftermarket upgrade to a distributor for these possibly ?
Another great video. But I think I will let a pro rebuild my mag!
How do I know what parts I will need?
Very Impressive. Most times i see a mag and i just say forgit about it, Lol
Hallo, Rachel, where is the engine number at the Allis Chalmers AM 2990-5 Danke und Gruss aus der Schweiz.
Soy de Coahuila Arteaga México como puedo obtener piezas ?
Envían a México ?
Какая милая девочка и как непривычно видеть девушку с отверткой в руках, да еще и с руками в масле.
Такое сейчас не увидеть уже, редкость несусветная.
Смотрю уже второй раз и каждый раз радуюсь Усп! и второму который не напишу чтобы не позорится незнанием языка. :)
Магнето весьма похоже на русские М-124, не полностью конечно, но характерная схожесть в решениях просматривается, любопытно было бы взять два разные и сравнить насколько они схожие.
Интересно еще русские здесь были ? отмечаемся если да.
Spoke of remove small gear did not show
😀😀😀👏👏
Hi
shes so adorable, id let her hand me wrenches
Hell I'd let HER do the job so I can hand her the wrenches.
I stumbled upon this video by accident and I have so many thoughts about this video... 1) I have worked on this type of stuff all my life and I have never come across a female of any age that has your level of interest in mechanical things and repair... awesome, 2) Are you married? 2a) If not are you interested? 2b) If so he is a lucky guy!
Great job!
I can’t get my rubber on can you do it for me?
Grow up!
nicholasyoder Why would you need a rubber when playing with yourself? Wouldn’t the rubber get in the way?
@@sgtcrab1 what are you talking about? I didn’t realize it was directional. Dang!
@@alvaroakatico9188 what do you mean?
I love a woman who gets her hands dirty
Are you Randy’s daughter
Little lady, you are making me tired.
