Hey Guys My magneto coils have a very flaky, crusty covering on them. I want to know what to do about it. Should I replace the whole assembly or can they run without the coating. I dont like the amount of debris it deposits in the motor so I want to know if I can clean them off or replace?

The covering is flaking off the coils. If it has not shorted, it will. I would replace it and recharge the magnets.

Looks like it's out of the car. If it were mine I'd split the trans from the engine and send the coil ring to Wally. He keeps some made up, so, the turnaround is quick, and the price is very reasonable. Look for cracked magnets and, check the magnet strength and recharge them if necessary while its split. I don't know what you have or haven't done to it, or why its out of the car, or your experience level, but, while it's out is the time to check out all you can. Sticking to your original question--IMHO I'd replace it with a rebuilt one for peace of mind and to avoid future catastrophic failure.

Mike is correct.

I need more info on this Wally character. The motors out because I had a terrible gear noise after a full rebuild of the rear axle. Since it was down and I need new bands anyway, I took the hogs head off to look around and found a cracked low speed drum. Long list of parts on the docket now. I am replacing pretty much anything I cant touch. The motor is very strong, Ill compression test it but thats all for now. Ive been working on it for a year now and Im looking to close the book on big repair for a bit. Mike, Ted, take a look at my other threads "clicking and Popping under my feet" and "Overhaul in Progress/ Gear Noise". See what you think, they are towards the top in the last few day on the forum.

You can also send your coil to RV Anderson 716-267-3526. He may do more field coils than any one in the business.

Brandon,
You cannot go wrong with Wally's work. Many here on the forum have used his rebuilt magneto coils and love them...myself included. You won't be sorry, unless you don't have it rebuilt:

Thanks Guys. Since so many have used him, any Idea on cost? I like hearing he has a fast turnaround. This damn project started with"I think I need new bands" then, "I need to rebuild the rear axle" to "Rebuild driveline", " Lets check out the triple gears by removing the hogs head" to Wow, a cracked drum." " I have to pull the motor" and now "Well I need to re-do the flywheel". Gotta Love It !

Im trying to break the flywheel off the trans. Does the trans and flywheel come off from the 4 bolts on the engine side of the crank? Also, does the shaft separate from the crank? I would think so. Thanks for the help guys.

P.S. I have a decent puller, as im sure there is pulling required somewhere.

Brandon,
I don't remember the exact cost, but he is competitive with the others.
He is very easy to talk with on the phone; give him a call.

Heres the outcome of the flywheel pulling. Take a look and tell me what you see.

With all the insulation coming off, and it out on the bench, I'd order a large pizza for supper today. When it's all gone, wipe out the box and put your coil ring into it and tape it up good. Call Wally or RV and send it off. I've found, with the flywheel still attached, the trans fits nicely into a 5 gal bucket. I then pressure wash the magnets/flywheel and inspect very closely for any cracked magnets. If you're this far along, I assume you have the MTFCA books. That will tell you how (with an extra coil ring, or, when you get yours back) to determine polarity of the magnets and ring and recharge the magnets. Holding your flywheel up on end, you want each magnet to hold a T piston (about 2 lbs) Good luck.

In addition to what Mike says, buy new brass screws and replace them at this time and also if the ring gear is wore out replace it. If you have a magnet charger the better way is to remove them and recharge them individually. There is another method to check for cracks that will show failure that you won't pick up with your eye. This makes it worthwhile if you or someone near you can recharge them individually.

I bought one from Wally's friend, Joe Bell, at Hershey last year for $200 exchange, if I recall correctly.

He has the earlier styles too, but the double coil models cost more.

Get a new coil ring, sandblast and check the magnets to make sure there not broken, recharge if necessary, make sure you have a copy of MTFCA's engine and transmission books and Ford service manual. Your going to have to "re-level" the magnet plates with a gauge or on a surface plate if possible and you'll have to know how to set the clearance between the magnet plates and the coil ring. While the transmission is apart check the clutch plate to make sure there not toast and check the drums for cracks or breaks. Get some telescoping gages and check the clearance on all the bushings, shafts, triple gears and triple gear pins to make sure they meet specified diameters and clearances. And to be honest with you I'd pull the oil pan (crankcase) and make sure to get it on a fixture and straighten it and check the fourth main diameters and clearances. New gaskets, and know that the hogshead is a kind of a trick to get on without having it leak later. While your at it machine out the pedal shaft holes for oil seals or O-rings. Or if your really ambitious machine them out and bush them. Don't forget to check the clutch spring tension. I think it's suppose to be something like 90 lbs when compressed to 2 inches. It's interesting to look at the coil ring and see where someone must of pulled pretty hard to get the starter out with out removing the bendix. The insulation is peeled off the coil by the starter cutout. I'd flip that motor over and check clearances on the rod caps and mains too while you've got it out. And as long as you've got the gasket set, pull the front cam cover off and replace the timing gears and the front motor seal. Now's also the time to pull the felt seal out from behind the flapper in the commutator and put in a neoprene seal. Also take a look at the front crankshaft pulley and if it's sloppy pull it off and put one of the new style on. I guess all I've really told you is what Mike Black was suggesting and there's probably more you could do. I mean what the heck pull the head and flush the engine and take the radiator and have it flushed and tested for any slow leaks. Take the fan and check the angle and inspect for cracks on the blades. Ok I'm done. Good luck and have fun. Oh and find a Model T buddy that lives close by and bribe him to help you. A couple good breakfasts at a restaurant on your tab can go a long way to get some work done. :-)

Mike, you should check out "Clicking and Popping under my feet" near the top of the list. Ive done quite a bit of what you mentioned. The trans is broken down completely(still gotta do drums). I have new trips going in, drums to replace, driveshaft tube bushing to put in. Im also painting everything I touch. The pans and hogs head are already painted. Between this thread and the other once all the work is done this baby will be mint. The frame, driveline,rear axle, tire rings,running gear and etc have already been painted as well. The parts list is assembled and this friday I begin ordering. Thanks Guys

Brandon, if you don't have a magnet re-charger, then contact Ron Patterson. He does a jam-up job of charging magnets. He has done 4 sets for me this summer and not a dud in the bunch. If you are not familiar with Ron, then put a shout out on this forum.

I might want to brag a bit on Wally's mag ring rebuilds. He is good!

Brandon,
I notice that somebody did not put safety wire on head of of bolts that secures the magnets together make sure that you do put safety otherwise they might came lose.

Brandon I think the field coil is 175 from Wally plus exchange, he and his wife do a great job on them, I've bought 4 or 5 and all have been great. You might want to order some shims for the field coil just in case when setting the gap. Look at the book but I think the range is .025 to .041 closer is better and the shims may come in handy helping you achieve the gap. Please do check your crank end play you don't want to go back together and have that become a problem.

Thanks! Im in a pile of parts right now. My garage smells like 1925 gear oil and grease. But, Im gonna need to get one. Ill for sure re-wire the bolts. Thanks for all the feedback boys, this forum is golden. I sure would like to know how they did this in the thirties without this huge safety net.

Brandon they still had 10 of thousands of Ts on the road and mechanics that were very familiar with the model T plus the ford dealerships. I think I read somewhere that they were still producing replacement engines as late as the late thirties. You are correct though about the wonderful people on the forum with hundreds of years of experience combined. A resource that will diminish if we don't get younger folks engaged and involved. While I don't post much I do lurk a lot and read the threads that continue to at least increase my knowledge however that knowledge has not equally increased my mechanical ability because of aptitude. As you will find some of these guys just have a greater aptitude in these areas and are our experts and resource. What a great group of guys and gals.

Well T's dont have radios, power controls, blue tooth, ipod jack or usb port and alarms, so Its hard to corner the young folks. If I wasnt in my present situation I cant honestly say I would have ever known anything about them or showed interest. It took me years to realize what great gramps had in the garage. It looked cool, but it was slow and I wasnt aloud to drive it. But now I am T crazy and I will try to inspire as many young people to remember that part of history as possible. Im 26 and have a very large group of friends back home in Texas who are a little peeved I waited to move across the country to work on Lizzie. I have to say the car does pop up in group conversation more than I thought it would. Those guys love it and I think one will end up with a truck and the other wants a Fordor.
